This guide covers how to export an elevation map as a GeoTIFF and import into ArcGIS to render the correct digital surface model.
Exporting GeoTIFF data
You can also use this guide to correctly display the GeoTIFF files for Orthomosaic and Plant Health maps. Please review how to export these data from DroneDeploy here.
The Elevation toolbox is available to all customers subscribed to Business or Enterprise plans. This set of tools equips users with elevation data that can be exported and displayed in GIS software for further analysis.
- Select the Map you wish to import from the DroneDeploy dashboard.
- Choose Elevation as your map type, and then Export the map:
- Enter an email address to receive the exported map. Select Raw Elevation Data as the Data Type, then specify the Resolution and Map Projection. Next, select GeoTIFF for the file type and finish by clicking Export to submit your request.
- This specific example is based on the Web Mercator Projection (EPSG:3857), but you can use the Map Projection that better suits your needs.
- We recommend starting with a lower resolution file (50 cm or 20 inches/pixel) and working your way down to the highest resolution that your computer can manage.
- You can export the Elevation Map using Raw Elevation Values as the Data Type, or you can choose to export it using the RGB Image option.
Upon receipt of your exported files in your emaIl inbox, click the download link to get a zipped file containing your data. When prompted, save the file to your computer.
Locate the downloaded files on your computer. Using the file extraction method of your choice, extract the elevation data from the zipped file.
- Open ArcCatalog.
- In the Catalog Tree, open the TIFF file you received with your download.
- Select the TIFF file, right click, and click on Properties.
- Within the Raster Dataset Properties, navigate to NoData Value under Raster Information and select the Edit function.
- Next, delete all the 0 values from each Band such that the NoData Value column is left blank. To finish, select OK.
When prompted, select Apply on the Raster Dataset Properties return screen.
- Select the TIFF file again, right click, and select Build Pyramids. Review that the Input Raster Dataset file path leads to the saved file. Then, select OK. It is important to leave the default settings as they are.
Review input raster dataset leads to the saved file.
Return to the Preview tab and confirm that your TIFF looks similar to the example below:
- You can now open ArcMap and start a new project.
- Next, click on the Add Data icon to import the Elevation Map. Simply select the file path to the TIFF file and select OK.
- Under the Layers tab, right click on the newly imported layer, and select Properties.
- Navigate your cursor to the last tab labeled Symbology and show RGB Composite. Then, check the box to enable Display Background Value. Finally, select OK to complete.
- Congratulations! You have now displayed your elevation map in ArcGIS.
