GIS mapping software is a powerful tool that allows users to make spatial queries and modify features. The process is similar to that of a spreadsheet, where users can apply formatting rules to columns and rows or edit individual cells directly. They can also populate data with formulas. With GIS, the user can also change the geometry of points and polygons. These features can be useful for many purposes, including economic development, health, and real estate.
The software also offers tools to analyze data, share maps, and create presentations. In addition, the software is free. You can use it on Windows, Linux, and Mac platforms. Once you install it on your computer, you can begin analyzing and visualizing data. Once you’ve finished, you can share the results with others.
GIS mapping software is an invaluable tool for spatial analysis, but it’s not necessary to be a GIS expert to use it. You can learn the basics of spatial analysis with an open source application such as QGIS or OpenLayers. If you’d like to get more advanced capabilities, try using free GIS software such as gvSIG.
