摘 要:
栅格数据结构简单、直观,非常利于计算机操作和处理,是GIS常用的空间基础数据格式。基于栅格数据的空间分析是GIS空间分析的基础,也是ArcGIS空间分析模(SpatialAnalyst)的核心内容。ArcGIS 空间分析模块(Spatial Analyst)提供了一个范围广阔且功能强大的空间分析和建模工具集,它允许用户从GIS数据中快速获取所需信息,并以多种方式进行分析操作,包括距离制图、密度制图、表面生成、表面分析、统计分析、重分类、栅格计算,等等。合理的学校空间位置布局,有利于学生的上课与生活。学校的选址问题需要考虑地理位置、学生娱乐场所配套、与现有学校的距离间隔等因素,从总体上把握这些因素能够确定出适宜性比较好的学校选址区。

The application of GIS in school location
Abstract:
Raster data structure is simple, intuitive,and very easy to computer operation and
treatment, it is the commonly used in GIS space based on data format. The space
analysis based on the grid data is the fundamental of GIS spatial analysis,also is
core content to ArcGIS space analysis module (Spatial Analyst). ArcGIS space
analysis module (Spatial Analyst) provides a wide range and powerful Spatial
analysis and modeling tool set,which allows users get the information quickly from
GIS data, and to provides various analysis operations, including distance drawing,
density drawing, surface formation, surface analysis, statistical
analysis,reclassification, and raster calcunation, and so on. Reasonable school
space position is good for the students of study and life. School issues consider
the site selection of the geographical position, places of entertainment facilities,
