ArcPad Tips & Tricks #2: Multiple layer definitions

Did you know that the AXF file format supports multiple layer definitions for a single feature class? This works in the same way as Layer files in ArcMap: the layer defines the symbology, which points to a feature class, which stores all of the data (both spatial and attributes). To set this up in ArcPad:
  1. Open the AXF in ArcPad studio
  2. Expand the Feature Tables node
  3. Right click on the table you wish to create the layer definition for, and select "Create New Layer". A new layer definition is added to the Feature Layers node
  4. You can rename the layer to whatever you like

And how is this useful I hear you ask. Well, a couple of ideas are:

  1. You could create different edit forms for different purposes. For example, you may have a layer for new features that are collected, and one for follow up inspections. You can specify different forms to ensure the correct fields are filled out in each inspection.
  2. You can combine the layer definitions with filters to create more complex symbology. For example, you may wish to categorise your roads layer into suburban roads, major roads and highways, and display them at different zoom scales.

ArcPad Tips & Tricks #1: Layer Icons

Did you know that you can set icons for your layers. These will appear in the Table of Contents and the Edit drop down menu, making it easier to differentiate between your layers.

For shapefiles, all you need to do is copy a .ico file, with the same base name as the shapefile, into the same directory. So, for example, if your shapefile is Roads.shp, name you .ico file Roads.ico.

The process is a bit more complicated with AXF files. You need to open up the axf in Application Builder, right click the layer and select "Set Layer Icon". You can clear the icon by selecting "Clear Layer Icon".

A good selection of sample icons can be found in C:\Program Files\ArcPad 7.1\Samples\Layer Icons. If you want to make your own, a good program is IcoFX. Your icons need to be 4bit 16x16 images.
