Since the question - What is GIS and what is not? - involves comparisons, we must look at the boundaries between the "ins" and the "outs", initially for the discipline and then for the technology. Inevitably these boundaries will be fuzzy, with lots of overlap. We will then attempt to...
所谓GIS就是 Geographic Information System的缩略形式，是能提供存储、显示、分析地理数据功能的软件。主要包括数据输入与编辑、数据管理、数据操作以及数据显示和输出等。从技术和应用的角度， GIS 是解决空间问题的工具、方法和技术；从学科的角度， GIS 是在地理学、 地图学 、 测量学 和计算机科学等学...
Geographical Information System (GIS) is a technical system, which is based on the Geospatial Database and adopts the method of geographic model analysis to provide various spatial and dynamic geographic information in time, and serves for geographic research and geographic decision-making. GIS has ...
GIS is a technology that is used to create, manage, analyze, and map all types of data. GIS connects data to a map, integrating location data (where things are) with all types of descriptive information (what things are like there). This provides a foundation for mapping and analysis that...
Data Management: Each definition of GIS mentions the storage and management of data. GIS is not just about displaying maps; it involves capturing, managing, and analyzing data in a spatial context. Integration of Data and Maps: These definitions stress location data and descriptive information. GIS...
•GIS is a tool to integratepeople. GIS functionalities cover a broad range of users, most of whom would not have such a well-defined framework if it were not for GIS itself. Consequently, there is better coordination among them.
Find the definition of GIS. Learn how this mapping and analysis technology is crucial for making sense of data. Learn from examples and find out why GIS is more important than ever.
GIS is used to display and analyze spatial data which are tied to databases. This connection is what gives GIS its power: maps can be drawn from the database and data can be referenced from the maps. When a database is updated, the associated map can be updated as well. GIS databases...
