Extract Layer Data

The two Extract Layers tools make it possible for you extract layer data from a particular area on the map. First you select the layers you want to include, and then you define an area of the map from which to extract the data. During the extract process, you can also define the format of the data you want to use. The data is then extracted from the map and zipped into a file. If you use the Extract and Email tool, you can also then email the data.

To extract map layer data:

1. On the Maps & Data Sources tab of the toolbar, click Extract Layers.

   

   The Extract Data wizard opens in the information panel.

   • If you selected the polygon, drag across the map to start a polygon.

     To change direction, click and then drag in a new direction. Shading appears to indicate that the polygon is filling in the space of the area. Double-click to end the polygon. You do not have to complete the shape, as long as the shading covers the area, you can double-click and the application completes the shape for you.

   • If you selected the rectangle, click the map where you want one corner of the area to begin, and then drag a rectangle to cover the area. Lift your finger off the mouse button to complete the rectangle.

     When you have completed the shape, a Geometry Captured! message appears.
