A sample GRF XML document
In your work you are not limited to StreetMap to create and maintain a geocoding and routing file. In fact, with minimal effort you can create your own GRF file.
The example below shows a fragment of a GRF document that contains two stops. As you examine the information below notice that both stops are enabled; therefore, they will be participating in the route generation. One of them has a collapsed callout box (property closed=“True”), and one has the comment field filled in.
<?xml version="1.0"?>
<GRFDOC version="1.1">

<STOPS>
<STOP enabled="true">
<LOCATION visible="true" closed="true">

You may want to create a custom tool that reads point features and saves the attributes automatically into the appropriate XML elements in the GRF file. A sample illustrating how you can create such a custom tool is available on the ArcScripts Web page (www.esri.com/arcscripts). To find the example, type “grf” in the keyword field. This sample has a tool that can be added to ArcMap, which will then allow you to create a GRF file based on a point layer in your map. The GRF file can then be added to ArcPad.
