Orthophotos (Orthomosaics)

Nira supports uploading and viewing orthophotos - also known as orthomosaics.

Current limitations (follow article to receive an update when these limitations are addressed):

• Can only View measurements and callouts/annotations that were created within the 3D viewer, can not Create or Edit
• Can not group measurements and callouts/annotations within the Layer list window
• No support for single-band orthophoto files (e.g. elevation maps). Currently, for basic visualization of elevation you may convert your elevation maps to RGBA before uploading to Nira.
• Automatic creations of asset thumbnails from within the orthophoto viewer
• Ortho facades (currently, only top-down orthophotos are supported)
• Can not view cameras or access photos within the orthophoto viewer

To upload an orthophoto:

1. Export an orthophoto from the application of choice, and select .tif or .tiff (GeoTIFF) as the output format. Currently, Nira only supports GeoTIFF formatted orthophotos. You should also configure your application to export the orthophoto with an alpha channel, which will prevent it from having black or white borders around it.

2. To upload, drag your .tif file into Nira (Learn more). You can also include geometry, texture, and camera  files if you'd like your orthophoto to be accompanied by 3D data. Follow our export guide for your application to learn how to export 3D data files. To add an orthophoto to an existing asset, follow our guide How can I upload additional files to an existing asset?

To access an orthophoto, just click on the asset once the processing of your upload is complete. Please be aware that if your asset includes 3D data files, you'll need to click on the '2D' button located in the lower right corner of the interface in order to activate the orthophoto viewer.

To adjust the visibility or opacity of orthophotos:

Your orthophotos are displayed at the top of the layer list window. Use the visibility toggle icon and opacity sliders to the right of each ortohphoto to adjust these settings.
