Is What You See, What You Get? GeospatialVisualizations Address Scale and UsabilityAashishChaudhary and Jeff BaumesUnlimited geospatial information now is at everyone’s fingertips with the proliferation of GPS-embedded mobile devices and large online geospatial databases. To fully understand these data and make wise decisions, more people are turning to informatics and geospatial visualization, which are used to solve many real-world problems.To effec tively gather information from data, it’s critical to address scalability and intuitive user interactions and visualizations. New geospatial analysis and visualization techniques are being used in fields such as video analysis for national defense, urban planning and hydrology.Why Having Data Isn’t Good Enough AnymorePeople are realizing that data are only useful if they can find the relevant pieces of data to make better decisions. This has broad applicability, from finding a movie to watch to elected officials deciding how much funding to allocate for an aging bridge. Information can easily be obtained, but how can it be sorted, organized, made sense of and acted on? The field of informatics solves this challenge by taking large amounts of data and processing them into meaningful, truthful insights.In informatics, two main challenges arise when computers try to condense information down to meaningful concepts: disorganization and size. Some information is available in neat, organized tables, ready for users to pull out the needed pieces, but most is scattered across and hidden in news articles, blog posts and poorly organized lists.Researchers are feverishly working on new ways to retrieve key ideas and facts from these types of messy data sources. For example, services such as Google News use computers that constantly "read" news articles and posts worldwide, and then automatically rank them by popularity, group them by topic, or organize them based on what the computer thinks is important to viewers. Researchers at places such as the University of California, Irvine, and Sandia National Laboratories are investigating the next approaches to sort through large amounts of documents using powerful supercomputers.The other obstacle is the sheer vo lume of data. It’s difficult to use informatics techniques that only work on data of limited size. Facebook, Google and Twitter have data centers that constantly process huge quantities of information to deliver timely and relevant information and advertisements to each person currently logged on..Figure 1. A collection of videos are displayed without overlap (top). The outline color represents how close each video matches a query. An alternate view (bottom) places thevideos on top of each other in a stack, showing only the strongest match result.Informatics is a key tool, but it’s not enough to simply find these insights that explain the data. Geospatial visualization bridges the gap from computer number-crunching to human understanding. If informatics is compared to finding the paths in a forest, visualization is like creating a visual map of those paths so a person can navigate through the forest with ease.Most people today are familiar with basic geospatial visualizations such as weather maps and Web sites for driving directions. The news media are starting to test more-complex geospatial visualizations such as online interactive maps to help navigate politicians’ stances on issues, exit polls and precinct reports during election times. People are just beginning to see the impact that well-designed geospatial visualizations have on their understanding of the world..Geospatial Visualization in the Real WorldPeople have been looking at data for decades, but the relevant information that accompanies the data has changed in recent years. In late 1999, Esri released a new software suite, ArcGIS, that could use data from various sources. ArcGIS provides an easy-to-use interface for visualizing 2-D and 3-D data in a geospatial context. In 2005, Google Earth launched and made geospatial visualization available to the general public.Geospatial visualization is becoming more significant and will continue to grow as it allows people to look at the totality of the data, not just one aspect. This enables better understanding and comprehension, because it puts the data in context with their surroundings. The following three cases demonstrate geospatial visualization use in real-world scenarios:1. Urban PlanningPlanners use geomodeling and geovisualization tools to explore possible scenarios and communicate their design decisions to team members or the general public. For example, urban planners may look at the presence of underground water and the terrain’s surrounding topology before deciding to build a new suburb. This is relevant for areas around Phoenix, for example, where underground water presence and proximity to a knoll or hill can determine the suitability of a location for construction.Figure 2. Videos from the same location are partially visible, resembling a stack of cards. Each video is outlined by the color representing the degree to which it matches the query.Looking at a 3-D model of a house with its surroundings gives a completely different perspective than just looking at the model of a house by itself. This also can help provide clear solutions to problems, such as changing the elevation of a building’s base to make it stand better.Urban planning is one of the emerging applications of computer-generated simulation. Cities’ rapid growth places a strain on natural resources that sustain growth. Water management, in particular, becomes a critical issue.The East Valley Water Forum is a regional cooperative of water providers east of Phoenix, and it’s designing a water-management plan for the next 100 years. Water resources in this region come from the Colorado River, the Salt River Project, groundwater, and other local and regional water resources. These resources are affected directly and indirectly by local and global factors such as population, weather, topography, etc.To best understand the relationship among water resources and various factors, the Arizona Department of Water Resources analyzes hydrologic data in the region using U.S. Geological Survey MODFLOW software, which simulates the status of underground water resources in the region. For better decision making and effective water management, a comprehensive scientific understanding of the inputs, outputs and uncertainties is needed. These uncertainties include local factors such as drought and urban growth.Looking at numbers or 2-D graphs to understand the complex relationship between input, output and other factors is insufficient in most cases. Integrating geospatial visualizations with MODFLOW simulations, for example, creates visuals that accurately represent the model inputs and outputs in ways that haven’t been previously presented.For such visualizations, two water surfaces are positioned side-by-side—coming from two different simulations—with contour lines drawn on top. In this early prototype, a simple solution—providing a geospatial plane that can be moved vertically—brings the dataset into a geospatial context. This plane includes a multi-resolution map with transparency. Because these water layers are drawn in geospatial coordinates, it matches exactly with the geospatial plane. This enables researchers to quickly see the water supplies of various locations.2. Image and Video AnalysisDefense Advanced Research Projects Agency launched a program, Video and Image Retrieval nd Analysis Tool (VIRAT), for understanding large video collections. The project’s core requirement is to add video-analysis capabilities that perform the following:• Filter and prioritize massive amounts of archived and strea ming video based on events.• Present high-value intelligence content clearly and intuitively to video analysts.• Reduce analyst workload while increasing quality and accuracy of intelligence yield.Visualization is an integral component of the VIRAT system, which uses geospatial metadata and video descriptors to display results retrieved from a database.Analysts may want to look at retrieval result sets from a specific location or during a specific time range. The results are short clips containing the object of interest and its recent trajectory. By embedding these results in a larger spatiotemporal context, analysts can determine whether a retrieved result is important.3. Scientific VisualizationU.S. Army Corps of Engineers’ research organ ization, the Engineer Research and Development Center, is working to extend the functionality of the Computational Model Builder (CMB) environment in the area of simulation models for coastal systems, with an emphasis on the Chesapeake and Delaware bays.The CMB environment consists of a suite of applications that provide the capabilities necessary to define a model (consisting of geometry and attribute information) that’s suitable for hydrological simulation. Their simulations are used to determine the impact that environmental conditions, such as human activities, have on bodies of water.Figure 3. Google Earth was used to display Chesapeake Bay’s relative salt (top) and oxygen (bottom) content (higher concentrations in red).One goal is to visualize simulation data post-processed by CMB tools. Spatiotemporal information, for example, is included in oxygen content and salinity data. Drawing data in geospatial context lets users or analysts see which locations are near certain features, giving the data orientation and scale that can easily be understood. Figure 3 shows the oxygen and salt content of Chesapeake Bay, where red shows higher concentrations and blue shows lower concentrations.Moving ForwardVisualizations that can be understood at all levels will be key in politics, economics, national security, urban planning and countless other fields. As information becomes increasingly complex, it will be harder for computers to extract and display those insights in ways people can understand.More research must be done in new geospatial analysis and visualization capabilities before we drown in our own data. And it’s even more important to educate people in how to use and interpret the wealth of analysis tools already available, extending beyond the basic road map.High schools, colleges and the media should push the envelope with new types of visuals and animations that show data in richer ways. The price of explaining these new views will be repaid when audiences gain deeper insights into the real issues otherwise hidden by simple summaries. Progress isn’t limited by the volume of available information, but by the ability to consume it.翻译:你所看到的,你得到了什么?地理空间可视化的处理规模和可用性作者:AashishChaudhary和包密斯·杰夫无限的空间信息现在就在每个人的指尖,其与扩散的嵌入式GPS移动设备和大型网上地理空间数据库。

Lesson 22 data analysis IIIntegrated Analytical Functions in a GISMost GIS's provide the capability to build complex models by combining primitive analytical functions. Systems vary as to the complexity provided for spatial modelling, and the specific functions that are available. However, most systems provide a standard set of primitive analytical functions that are accessible to the user in some logical manner. Aronoff identifies four categories of GIS analysis functions. These are :Retrieval, Reclassification, and Generalization;Overlay Techniques;Neighbourhood Operations; andConnectivity Functions.The range of analysis techniques in these categories is very large. Accordingly, this section of the book focuses on providing an overview of the fundamental primitive functions that are most often utilized in spatial analyses.Retrieval, Reclassification and GeneralizationPerhaps the initial GIS analysis that any user undertakes is the retrieval and/or reclassification of data. Retrieval operations occur on both spatial and attribute data. Often data is selected by an attribute subset and viewed graphically. Retrieval involves the selective search, manipulation, and output of data without the requirement to modify the geographic location of the features involved.Reclassification involves the selection and presentation of a selected layer of data based on the classes or values of a specific attribute, e.g. cover group. It involves looking at an attribute, or a series of attributes, for a single data layer and classifying the data layer based on the range of values of the attribute.Accordingly, features adjacent to one another that have a common value, e.g. cover group, but differ in other characteristics, e.g. tree height, species, will be treated and appear as one class. In raster based GIS software, numerical values are often used to indicate classes. Reclassification is an attribute generalization technique. Typically this function makes use of polygon patterning techniques such as crosshatching and/or color shading for graphic representation.In a vector based GIS, boundaries between polygons of common reclassed values should be dissolved to create a cleaner map of homogeneous continuity. Raster reclassification intrinsically involves boundary dissolving. The dissolving of map boundaries based on a specific attribute value often results in a new data layer being created. This is often done for visual clarity in the creation of derived maps. Almost all GIS software provides the capability to easily dissolve boundaries based on the results of a reclassification. Some systems allow the user to create a new data layer for the reclassification while others simply dissolve the boundaries during data output.One can see how the querying capability of the DBMS is a necessity in thereclassification process. The ability and process for displaying the results of reclassification, a map or report, will vary depending on the GIS. In some systems the querying process is independent from data display functions, while in others they are integrated and querying is done in a graphics mode. The exact process for undertaking a reclassification varies greatly from GIS to GIS. Some will store results of the query in query sets independent from the DBMS, while others store the results in a newly created attribute column in the DBMS. The approach varies drastically depending on the architecture of the GIS software.Topological OverlayThe capability to overlay multiple data layers in a vertical fashion is the most required and common technique in geographic data processing. In fact, the use of a topological data structure can be traced back to the need for overlaying vector data layers. With the advent of the concepts of mathematical topology polygon overlay has become the most popular geoprocessing tool, and the basis of any functional GIS software package.Topological overlay is predominantly concerned with overlaying polygon data with polygon data, e.g. soils and forest cover. However, there are requirements for overlaying point, linear, and polygon data in selected combinations, e.g. point in polygon, line in polygon, and polygon on polygon are the most common. Vector and raster based software differ considerably in their approach to topological overlay.Raster based software is oriented towards arithmetic overlay operations, e.g. the addition, subtraction, division, multiplication of data layers. The nature of the one attribute map approach, typical of the raster data model, usually provides a more flexible and efficient overlay capability. The raster data model affords a strong numerically modelling (quantitative analysis) modelling capability. Most sophisticated spatial modelling is undertaken within the raster domain.In vector based systems topological overlay is achieved by the creation of a new topological network from two or more existing networks. This requires the rebuilding of topological tables, e.g. arc, node, polygon, and therefore can be time consuming and CPU intensive. The result of a topological overlay in the vector domain is a new topological network that will contain attributes of the original input data layers. In this way selected queries can then be undertaken of the original layer, e.g. soils and forest cover, to determine where specific situations occur, e.g. deciduous forest cover where drainage is poor.Most GIS software makes use of a consistent logic for the overlay of multiple data layers. The rules of Boolean logic are used to operate on the attributes and spatial properties of geographic features. Boolean algebra uses the operators AND, OR, XOR, NOT to see whether a particular condition is true or false. Boolean logic represents all possible combinations of spatial interaction between different features. The implementation of Boolean operators is often transparent to the user.Generally, GIS software implements the overlay of different vector data layers by combining the spatial and attribute data files of the layers to create a new data layer. Again, different GIS software utilize varying approaches for the display andreporting of overlay results. Some systems require that topological overlay occur on only two data layers at a time, creating a third layer. This pairwise approach requires the nesting of multiple overlays to generate a final overlay product, if more than two data layers are involved. This can result in numerous intermediate or temporary data layers. Some systems create a complete topological structure at the data verification stage, and the user merely submits a query string for the combined topological data. Other systems allow the user to overlay multiple data layers at one time. Each approach has its drawbacks depending on the application and the nature of the implementation. Determining the most appropriate method is based on the type of application, practical considerations such as data volumes and CPU power, and other considerations such personnel and time requirements. Overall, the flexibility provided to the operator and the level of performance varies widely among GIS software offerings.The following diagram in Fingure 1 illustrates a typical overlay requirements where several different layers are spatially joined to created a new topological layer.By combining multiple layers in a topological fashion complex queries can be answered concerning attributes of any layer.Neighbourhood OperationsNeighbourhood operations evaluate the characteristics of an area surrounding a specific location. Virtually all GIS software provides some form of neighbourhood analysis. A range of different neighbourhood functions exist. The analysis of topographic features, e.g. the relief of the landscape, is normally categorized as being a neighbourhood operation. This involves a variety of point interpolation techniques including slope and aspect calculations, contour generation, and Thiessen polygons. Interpolation is defined as the method of predicting unknown values using known values of neighbouring locations.36 Interpolation is utilized most often with point based elevation data.Figure 2 illustrates a continuous surface that has been created by interpolating sample data points.Elevation data usually takes the form of irregular or regular spaced points. Irregularly space points are stored in a Triangular Irregular Network (TIN). A TIN is a vector topological network of triangular facets generated by joining the irregular points with straight line segments. The TIN structure is utilized when irregular data is available, predominantly in vector based systems. TIN is a vector data model for 3-D data.An alternative in storing elevation data is the regular point Digital Elevation Model (DEM). The term DEM usually refers to a grid of regularly space elevation points. These points are usually stored with a raster data model. Most GIS software offerings provide three dimensional analysis capabilities in a separate module of the software. Again, they vary considerably with respect to their functionality and the level of integration between the 3-D module and the other more typical analysis functions.Without doubt the most common neighbourhood function is buffering. Buffering involves the ability to create distance buffers around selected features, be it points,lines, or areas. Buffers are created as polygons because they represent an area around a feature. Buffering is also referred to as corridor or zone generation with the raster data model. Usually, the results of a buffering process are utilized in a topological overlay with another data layer. For example, to determine the volume of timber within a selected distance of a cutline, the user would first buffer the cutline data layer. They would then overlay the resultant buffer data layer, a buffer polygon, with the forest cover data layer in a clipping fashion. This would result in a new data layer that only contained the forest cover within the buffer zone. Since all attributes are maintained in the topological overlay and buffering processes, a map or report could then be generated.Buffering is typically used with point or linear features. The generation of buffers for selected features is frequently based on a distance from that feature, or on a specific attribute of that feature. For example, some features may have a greater zone of influence due to specific characteristics, e.g. a primary highway would generally have a greater influence than a gravel road. Accordingly, different size buffers can be generated for features within a data layer based on selected attribute values or feature types.Connectivity AnalysisThe distinguishing feature of connectivity operations is that they use functions that accumulate values over an area being traversed.37 Most often these include the analysis of surfaces and networks. Connectivity functions include proximity analysis, network analysis, spread functions, and three dimensional surface analysis such as visibility and perspective viewing. This category of analysis techniques is the least developed in commercial GIS software. Consequently, there is often a great difference in the functionality offered between GIS software offerings. Raster based systems often provide the more sophisticated surface analysis capabilities while vector based systems tend to focus on linear network analysis capabilities. However, this appears to be changing as GIS software becomes more sophisticated, and multi-disciplinary applications require a more comprehensive and integrated functionality. Some GIS offerings provide both vector and raster analysis capabilities. Only in these systems will one fund a full range of connectivity analysis techniques.Proximity analysis techniques are primarily concerned with the proximity of one feature to another. Usually proximity is defined as the ability to identify any feature that is near any other feature based on location, attribute value, or a specific distance. A simple example is identifying all the forest stands that are within 100 metres of a gravel road, but not necessarily adjacent to it. It is important to note that neighbourhood buffering is often categorized as being a proximity analysis capability. Depending on the particular GIS software package, the data model employed, and the operational architecture of the software it may be difficult to distinguish proximity analysis and buffering.The identification of adjacency is another proximity analysis function. Adjacency is defined as the ability to identify any feature having certain attributes that exhibit adjacency with other selected features having certain attributes. A typical example isthe ability to identify all forest stands of a specific type, e.g. specie, adjacent to a gravel road.Network analysis is a widely used analysis technique. Network analysis techniques can be characterized by their use of feature networks. Feature networks are almost entirely comprised of linear features. Hydrographic hierarchies and transportation networks are prime examples. Two example network analysis techniques are the allocation of values to selected features within the network to determine capacity zones, and the determination of shortest path between connected points or nodes within the network based on attribute values. This is often referred to as route optimization. Attribute values may be as simple as minimal distance, or more complex involving a model using several attributes defining rate of flow, impedance, and cost.Three dimensional analysis involves a range of different capabilities. The most utilized is the generation of perspective surfaces. Perspective surfaces are usually represented by a wire frame diagram reflecting profiles of the landscape, e.g. every 100 metres. These profiles viewed together, with the removal of hidden lines, provide a three dimensional view. As previously identified, most GIS software packages offer 3-D capabilities in a separate module. Several other functions are normally available. These include the following functions :user definable vertical exaggeration, viewing azimuth, and elevation angle;identification of viewsheds,e.g. seen versus unseen areas;the draping of features, e.g. point, lines, and shaded polygons onto the perspective surface;generation of shaded relief models simulating illumination;generation of cross section profiles;presentation of symbology on the 3-D surface; andline of sight perspective views from user defined viewpoints.While the primitive analytical functions have been presented the reader should be aware that a wide range of more specific and detailed capabilities do exist.。
