How to export your Agisoft Metashape project for Nira

First, a note on georeferencing:

To best utilize all of Nira's features, it is recommended that you export your files using georeferenced coordinates. If you plan to use georeferenced coordinates, you'll need to determine an appropriate coordinate system for your project. Here's how:

• Choose a UTM Zone if you're not sure which coordinate system to use:

Simply drag one of your project's photos into the UTM Zone Identification webpage and make note of the UTM Zone displayed. You'll use it in one of the steps below.

• If you already have a preferred coordinate system:

Be sure it's cartesian. To check this, look up the EPSG number here: https://epsg.io. Ensure that it includes "Coordinate System: Cartesian 2D CS". For example, the page for EPSG:28992 confirms that is cartesian, whereas EPSG:4326 is not. If your preferred coordinate system is not cartesian, you should use a UTM Zone instead -- see the first bullet point above to learn how.

To export your files:

File > Export > Export Model... > Save as type: Wavefront OBJ (*.obj)

Be sure to enable Export texture (choose PNG) and Include comment Generated with Agisoft Metashape.  Everything else can be disabled.

You can use Local Coordinates (m), but we strongly suggest using a cartesian based Coordinate System. If you're not sure what to choose, read the tips at the beginning of this page.

File > Export > Export Cameras... > Save as type: Blocks Exchange (*.xml)

Coordinate System setting needs to match the coordinate system you chose during the OBJ export:

Be sure to disable Tie points and Control points so the xml file can be smaller in size.

After uploading to Nira, you’ll have all of your photos and orthomosaics available within the Show Photo… button.  Be sure your photos do not have comma ( , ) characters in the filename.
