Overview of creating a new map
A map is the fundamental component you work with in ArcPad. The ArcPad map file (.apm) stores a list of the map layers and their properties in your ArcPad session. A map lists all your layers together with the geographic extent and projection of the map. When you begin an ArcPad session, you must first open an existing map or create a new map by adding layers of data or information.
Once shapefiles, ArcPad AXF files, images, graphics layers, photo layers, StreetMap layers, or Internet data are added to your ArcPad map, you determine whether or not they are displayed, edited, updated, moved. Each file appears in ArcPad as a layer in the map.
