Introduction To ArcGIS
Keywords: Tables, joining, relates, sorting, data analysis Category: Data Analysis Software: ArcGIS 8/9.x Problem: I have information in a table that I would like to join to a point, polygon or line layer. Description: Often times, the information you want to display or analyze within GIS is in two different places or formats. Often you will have a map of a standard area, like the counties in a state or the states of a country, and you will want to add external data to them so you can look at that external data in a spatial context. In this recipe we will look at how to join data to a shapefile. Scenario: Ever since the work of John Snow and his mapping of Cholera cases, mapping cases and frequencies of diseases can help to find sources and cures.

Mapping and Modeling Tutorials
Hands On articles build skills These tutorials demonstrate how GIS can help measure areas of coverage, response times, slope, and other factors. A model is a set of rules or procedures for representing a phenomenon or predicting an outcome. Mike Price has written a series of articles that show how to construct networking models using the ArcGIS Network Analyst and ArcGIS Spatial Analyst extensions.
