DroneDeploy

3D Model:

1. Select a map from the available Projects, and then click Export
2. From the Export list, choose 3D Model
3. From the 3D Model Exports Panel, click Export
4. Wait for the model to be ready for download, which may take several minutes.  Once it is available, a download link will appear, providing access to the 3D Model (OBJ), Material Definition file (MTL), and Textures (JPG) in a zipped archive. Once you've downloaded the archive, unzip all the files into a folder and upload the extracted files to Nira.

Note: DroneDeploy will generate the 3D model using georeferenced coordinates based on the coordinate system you've set for your project. However, there are two important caveats to keep in mind:

1. As of the time this help article was written, DroneDeploy incorrectly labels the EPSG code of the 3D model as 3857. This is not accurate, the actual coordinate system will be whatever you set for project.
2. The OBJ file for the 3D model does not contain any embedded information about the coordinate system. Therefore, when uploading to Nira, Nira will need to reference either the orthomosaic or the point cloud, both of which include the georeferencing data Nira needs to identify the coordinate reference system.

Here’s an example of a georeferenced asset that was processed in DroneDeploy and uploaded to Nira. It includes a 3D textured mesh, a point cloud, and an orthomosaic, all georeferenced to the local coordinate system of the site:

Orthomosaic and Point Cloud downloads are georeferenced and supported in Nira.

Orthomosaic / GeoTIFF Map: 

1. Select a map from the available Projects, and then click Export
2. From the Export list, choose GeoTIFF Map
3. From the GeoTIFF Map Exports Panel, choose Single Image and then choose Max Available for the Resolution (Nira supports orthomosaic files of unlimited size), and then click Export
4. Wait for the map to be ready for download, which may take several minutes.  Once it is available, a download link will appear, providing access to the GeoTIFF Map. Once you've downloaded the archive, unzip all the files into a folder and upload the extracted files to Nira.

Point Cloud:

1. Select a map from the available Projects, and then click Export
2. From the Export list, choose Point Cloud
3. From the Point Cloud Exports Panel, specify the coordinate system (it's important that you choose the same coordinate system as you did with the Orthomosaic since they are both georeferenced), and then click Export
4. Wait for the Point Cloud to be ready for download, which may take several minutes.  Once it is available, a download link will appear, providing access. Once you've downloaded the archive, unzip all the files into a folder and upload the extracted files to Nira.

Limitations:

Drone Deploy does not permit the download of camera alignment data. As a result, your photos cannot be referenced relative to the 3D model in Nira, causing you to miss out on valuable inspection features.  A workaround is to process the model on your laptop or computer using photogrammetry desktop software, many of which are either free or offer free trial periods. For a comprehensive list of software that produces camera alignment data, please refer to the following help article: https://help.nira.app/hc/en-us/articles/26866140610459-What-photogrammetry-software-is-compatible-with-Nira

Another advantage of processing your own data is that, based on our experience, the resulting model is of much higher quality than what DroneDeploy can produce.

Uploading Textured Mesh and Point Clouds together:

For optimal alignment, it is required to use the same EPSG code for both the 3D Model, orthomosaic GeoTiff, and the point cloud LAS.  Since DroneDeploy does not allow for specifying the coordinate system of the 3D Model, it's important to export your orthomosaic GeoTiff and point cloud LAS using the same coordinate system as your project (do not export using EPSG 3857, see above).
