  1. Tap the Table of Contents button. The layers you selected previously are listed, each with a check in the Visible check box and the Identify check box. The Edit check box is, by default, unchecked.

  2. You can change the order in which layers are drawn by tapping on the Move Up or Move Down arrow buttons. The layers at the bottom are drawn before the layers at the top. Move the Customers layer up so that it is drawn after and on top of the Road layer.
  3. Tap the Land Use layer to select it; the layer is highlighted in blue.

  4. Double-tap the Land Use layer or tap the Layer Properties button. The Layer Properties dialog box is displayed for the Land Use layer.

    The Information page is displayed first; you can see that the Title field has the name Land Use in it. This is also the title that is used to name the layers in the Table of Contents.
  5. Tap the right arrow and then tap the Symbology tab to view the layer symbology. You can change symbology directly in the field using ArcPad or via the ArcPad Data Manager tools for ArcGIS Desktop. For more information about symbolization, see section, Symbolizing your data

  6. Tap the Attributes tab to see the fields associated with the Land Use layer. The USE_CODE field is displayed in red to indicate which field is being used to render the attribute base symbology. Later, you will change the values of these fields after you have inspected a plot of land.

    The “I” checkbox column indicates whether the layer has an index. If the checkbox for Geometry is checked, the layer has a spatial index. If the checkbox for a field is checked, an attribute index exists for the corresponding field. To add an index, simply check the Index checkbox for that attribute field.
