Pairing True Ortho with DSM
Nearmap’s True Ortho (high-resolution at 15cm GSD) is a perfect pairing with Nearmap’s DSM. The perfect alignment will enable users to view, edit and analyse features from the DSM using the True Ortho product as a visual guide.
Use the DSM geocoded .tif file that corresponds to the True Ortho file you are using.
- Add the DSM layer to the project in the same way you added the True Ortho layer:
- Select Layer → Add Layer → Add Raster Layer from the top menu.
- Browse and select the geocoded .tif file.
- Double click the DSM layer in the Layers Panel to access its Layer Properties, then select the Transparency option:
- Change the Global Transparency to a percentage that allows you to see the True Ortho layer under the DSM layer. Click Apply, then OK:
