2. Locating Data
Many of the databases you use in your work contain information on customers, prospects, businesses, facilities, and so on. One way you can use your data with TransCAD is to join the data to an existing map layer.
Another way to use your data with TransCAD is to locate your data on a map by creating a new geographic file that contains a point feature for every record in your database. This is sometimes known as pin mapping, because it is like hanging a paper map on the wall and marking the locations of interest with pushpins.
