Analysis Tools

In addition to creating digital map, GIS also facilitates users to apply the analysis tools to calculate, do statistics, and process with the digital map. Then, users are able to handle and analyze the geographic data to make the best policy. SuperGIS Desktop 10 provides "Chart", "Add XY Data", "Grid Maker", "Geoprocessing Tools", "Buffer", etc. "Chart" is introduced in "Creating Charts"; the other tools are introduced in this chapter.

First section Adding XY data is to introduce how to add the data from the database to SuperGIS Desktop 10 to easily create a point layer with X,Y coordinates. Buffering explains the meaning of buffering and the method to use Buffer. Geoprocessing Tools shows how to apply Geoprocessing Tools, such as dissolve, merge, clip, union, etc. Spatial Join will be introduced in Spatial Join, explaining how to utilize the spatial relationship between layers to combine the attributes. The last section, Grid Maker, shows how to create a grid layer with the tool.
