1. Locate your site in Promap. See Choosing how to locate your site for details.
2.Click the Export Data toolbar.
3. Before you export the mapping data you need to define the area you would like to export. There are three methods that can be used to define the export area: by shape, custom or export area frame. Some of the export options such as Aerial Photos and DSM/DTM Data will only be available as rectangles.
Please note, that there are size restrictions in place on some of the map layers, this is to ensure that the export frame you define can be seen. If you set an export frame that is too large for the map layer you are currently viewing Promap will either recommend you switch to an alternative map layer or in the case of exports larger than 200KM2 it will ask you to complete a Large area data quote form see Large Scale Exports:
