Unit1 What is Geomatics? 3页Data plotting (presentation) is handled through the use of mapping and other illustrative computer programs; the presentations are displayed on computer screens (where interactive editing can occur) and are output on paper from digital plotting devices. 数据绘图（描述，表达）是通过使用绘图和其他示范的计算机程序；这种表达显示在电脑屏幕（可以进行交互式编辑）和通过数字绘图设备输出到纸上。
Once the positions and attributes of geographic entities have been digitized and stored in computer memory, they are available for use by a wide variety of users. Through the use of modem information technology (IT), geomatics brings together professionals in the following disciplines: surveying, mapping, remote sensing, land registration, civil and marine engineering, forestry, agriculture, planning and development, geology, geographical sciences, infrastructure management, navigation, environmental and natural resources monitoring, and computer science.Other Definitions of Geomatics.一旦地理实体的位置和属性已被数字化并存储在计算机的内存中，它们即可以被各种各样的用户使用。
测绘专业英语作文（中英文实用版）{z}Title: Surveying and Mapping Profession - An Overview in English Surveying and Mapping is a specialized field that plays a crucial role in various industries such as construction, engineering, urban planning, and geospatial technology.It involves the process of collecting data and making detailed measurements of the Earth"s surface to create accurate representations of the physical features.This essay aims to provide an overview of the surveying and mapping profession, highlighting its importance and key aspects of the field.Firstly, the surveying and mapping profession is vital in the construction industry.It provides the necessary data and information required for planning, designing, and executing construction projects.surveyors and mappers determine the boundaries of properties, identify suitable locations for structures, and create detailed plans that serve as the foundation for construction activities.Secondly, the engineering field heavily relies on surveying and mapping.Engineers use surveying data to design and construct infrastructure projects such as roads, bridges, canals, and dams.accurate measurements and mapping ensure the safety, functionality, and efficiency of these projects, making surveying and mapping an integral part of the engineering process.Furthermore, the urban planning sector benefits significantly from the surveying and mapping profession.surveyors and mappers provide essential data for creating urban development plans, zoning regulations, and land-use policies.their work helps in managing and preserving natural resources, minimizing environmental impact, and enhancing the overall quality of life in urban areas.In addition, the geospatial technology industry leverages the surveying and mapping profession to gather and analyze spatial data.This data is used in various applications such as GPS navigation, remote sensing, and geographic information systems (GIS).The advancements in technology have revolutionized the surveying and mapping field, enabling the use of drones, satellite imagery, and digital mapping tools for more accurate and efficient data collection.Moreover, the surveying and mapping profession encompasses various specialized areas such as topographic mapping, hydrographic surveying, and geodetic surveying.Topographic mapping involves creating detailed maps that depict the natural and man-made features of a specific area.Hydrographic surveying focuses on mapping bodies of water, including oceans, lakes, and rivers.Geodetic surveying deals with the measurement and mapping of large-scale geographic areas, ensuring the accuracy of coordinates and measurements across different regions.In conclusion, the surveying and mapping profession is of paramountimportance in various industries.It provides the necessary data and information for construction, engineering, urban planning, and geospatial technology projects.The advancements in technology have revolutionized the field, enabling more accurate and efficient data collection and analysis.As the world continues to evolve, the surveying and mapping profession will play a crucial role in shaping our built environment and utilizing geospatial data for sustainable development.。
Uuit1 What is Geomatics? （什么是测绘学）Geomatics Defined（测绘学定义）Where does the word Geomatics come from?（Geomatics－测绘或地球空间信息学，这个名词是怎么来的呢？）GEODESY+GEOINFORMATICS=GEOMATICS or GEO- for earth and –MATICS for mathematical or GEO- forGeoscience and -MATICS for informatics. （大地测量学＋地理信息学＝GEOMATICS 测绘学或者geo 代表地球，matics 代表数学，或者geo 代表地球科学，matics 代表信息学）It has been said that geomatics is many things to many people.（据说测绘学这个词对不同的人有不同的理解）The term geomatics emerged first in Canada and as an academic discipline; it has been introducedworldwide in a number of institutes of higher education during the past few years, mostly by renamingwhat was previously called “geodesy” or “surveying”, and by adding a number of computer scienceand/or GIS-oriented courses.（这个术语【term 术语】作为一个学科【academic discipline 学科】第一次形成【emerge】于加拿大；在过去的几年里被全世界的许多高等教育研究机构所熟知，通常是以前的“大地测量学”或“测量学”在引入了许多计算机科学和GIS 方向【或“基于GIS”】的课程后重新命名的。
Geomatics is a relatively new scientific term created by Pollock and Wright in 1969, with the intention of combining the terms geodesy and geoinformatics.It includes the tools and techniques used in Surveying and Mapping, Remote Sensing (RS), Cartography, Geographic Information Systems (GIS), Global Navigation Satellite Systems (GNSS, i.e.,GPS, Glonass, Galileo, Compass),Photogrammetry, Geography, Geosciences, Computer Sciences, Information Science and various spatial observation technologies, land development and environmental sciences, etc.测绘学是一种相对较新的科学术语由波洛克和赖特在1969年提出，目的是将大地测量学与地理信息学结合起来。
它包括的工具和技术应用于测绘、遥感(RS)、地图学、地理信息系统(GIS)、全球导航卫星系统(GNSS,即。
、GPS、Glonass、伽利略、北斗),摄影测量、地理学、地球科学、电脑科学、信息科学和各种空间观测技术、土地开发、环境科学等。
Surveying may be defined as the tech nology and science of the study of earth’s shape and size, as well as making measurements of the relative positions of natural and man-made features on, above or below the earth’s surface, and representing these information in analog forms as contoured maps or sections, paper plan or chart, or as figures in report tables, or in digital form as a three dimensional mathematical model stored in the computer.测量的技术和科学可以定义为研究地球的形状和大小,以及测量位于地球外表上或者低于或者高于地球外表的自然的或人造的物体的相对位置,并将这些信息以模拟形式的波状外形的地图、剖面图、论文计划、图表、数据报告表中呈现或以数字形式存储在电脑三维数学模型中。
