Fieldwork Workflow: ArcMap to Mappt
Collecting data in the field is a multi-phased project, as we’ve outlined in previous blog posts. In this post we’ll walk you through a simple user story of the fieldwork process. The workflow will involve:
- Importing imagery from Esri’s ArcGIS Desktop 10.3 to Mappt
- Collecting vector data in the field
- Exporting the vector data back into ArcGIS Desktop 10.3
We’ll be using a natural colour ECW image of the South West of Western Australia, as shown below.
1. Create your project in Esri’s ArcMap. Load the imagery in.
2. Ensure that the WGS84 projection is used within your ArcMap Project. This is done by right-clicking ‘Layers’ in the Table of Contents sidebar and selecting ‘Properties’. Under the ‘Coordinate System’ tab, ensure that WGS84 is selected.
3. A section of the ECW can be clipped to create a smaller image file, which will make it load faster in Mappt. This can be done by using the Zoom Tool to zoom in on a smaller section of the ECW in Esri’s ArcMap.
4. Export the imagery from ArcMap by right-clicking the layer of imagery that you want to export, and selecting Data > Export Data. This will load the Export Data dialog box.
If you only want the extent shown on your display – i.e. clipping the image to the currently zoomed display – select ‘Data Frame (Current)’ under Spatial References.
Export the image as a JP2 file – as Mappt supports this format plus ECW.
5. Move the imagery onto the tablet you’re using by transferring it directly from the computer, or by using a third-party app such as Google Drive and Dropbox.
6. Load the imagery into Mappt by:
- Navigate to the imagery and select the file to be imported.
7. Your imagery will now appear in Mappt.
8. Use Mappt to collect your data. Below is an example of the data that can be collected in Mappt.
9. Export the shapefile from our mobile GIS back into Esri’s ArcMap (instructions for this can be found in this blog post). Your shapefile should now show in ArcMap.
We hope you found this blog post useful. If you encountered any problems, please let us know via the Mappt Forum.
