How to export imagery from Mappt to ArcMap 10.3

Mappt has the ability to export ECW and JP2 imagery from Mappt to use in Esri‘s ArcMap 10.3. This allows you to edit your data in ways like changing the imagery bands and extent.

In this post you will learn how to export imagery from Mappt to ArcMap, using natural colour ECW imagery of Australia’s South West (see below).

1. Load your image in Mappt and ensure that you know where the file is located in your device’s filesystem.

2. Make sure that the projection selected for the Mappt Project is WGS84.

3. Once complete, tap the Save button to open the Load/Save Project dialog window and select ‘Save Project’.

4. Transfer the imagery to your computer directly, or by using third-party apps such as Google Drive or Dropbox.

5. Open Esri’s ArcMap and start a New Project.

6. Open the Catalog sidebar in ArcMap and connect to the folder where the ECW or JP2 imagery is saved. Right-click the image and select ‘Properties’.

7. Ensure that the projected co-ordinate system of ArcMap is the same as that of Mappt, which was in WGS84.

8. Input the imagery into your ArcMap Project by either:

  • Tapping on File > Add Data > Add Data and selecting the image; or
  • Dragging the file from the Catalog sidebar into the Table of Contents or the Map Screen in ArcMap.

9. Your imagery should now be rendered in Esri’s ArcMap. You may have to select the option ‘Zoom to Layer’ to view the full extent of the imagery.
