What metadata is needed to use measurement tools in Oriented Imagery Viewer?
Hi all,
I've been trying to figure what metadata is needed to be able to use measurement tools in Oriented Imagery Viewer. I've created an Oriented Imagery catalog from aerial oblique imagery service (https://sampleserver6.arcgisonline.com/arcgis/rest/services/Oblique/WU_Oblique/ImageServer) . Looking at the resulting exposure points - they have CamOri field with detailed camera orientation. I've also used DEM service when I created this catalog. But I'm still unable to use measurement tools with this oriented imagery catalog:
This is the content of the oic:
{"type": "OIC", "version": "2.1", "properties": {"Name": "test8", "Description": "test", "Tags": "OrientedImagery", "ServiceURL": "https://services6.arcgis.com/YtqGNFEdrYd1pjuW/arcgis/rest/services/test8_ExposurePoints/FeatureServer/1", "OverviewURL": "https://tiles.arcgis.com/tiles/YtqGNFEdrYd1pjuW/arcgis/rest/services/test8_CoverageMap/VectorTileServer", "DefaultAttributes": {"CamHeading": "", "CamPitch": "", "CamRoll": "0", "HFOV": "", "VFOV": "", "AvgHtAG": "", "FarDist": "", "NearDist": "", "OIType": "T", "SortOrder": "", "CamOffset": "", "Accuracy": "", "ImgPyramids": "", "DepthImg": "", "ExternalViewer": "", "ImgRot": "", "ImageryType": "Aerial Oblique Camera"}, "About": "", "ImageField": "", "ImagePrefix": "", "VideoPrefix": "", "DepthImagePrefix": "", "SourceImagePrefix": "", "MaxDistance": "", "DEMPrefix": "I||https://elevation3d.arcgis.com/arcgis/rest/services/WorldElevation3D/Terrain3D/ImageServer", "Credentials": {"Username": "", "Password": ""}, "Variables": {}, "Filters": {}, "Copyright": {"text": "test", "url": ""}, "PointsSource": "D:\\Temp\\oblique\\oblique\\orient_test\\test8.gdb\\test8_ExposurePoints", "CoverageSource": "D:\\Temp\\oblique\\oblique\\orient_test\\test8.gdb\\test8_CoverageMap"}}
What data is needed for the measurement functions in OI Viewer to be available?
Thank you,

For distance and area tool to be activated, you need depth image defined in the feature service.
If you have a depth image, then you can define it in DepthImg field in the feature class.
See the documentation - oriented-imagery/OrientedImageryCatalog_Schema.pdf at master · Esri/oriented-imagery · GitHub
Snippet
If the depth image is same for all the images, then you can just define it in the properties and republish the OIC.
But if every image has its own depth (which i think is applicable in your case), then you can define in the attribute table. For every record, there will be a depth image. Here, you don't need to define it in the properties.
You need to republish the calalog, but you don't need to compute the feature coverage and coverage polygon again.
Hi,
I think you misunderstood what I was trying to convey here or maybe I was not clear enough.
You will require depth images to enable area and distance tool. I think you don't have depth images with you.
Depth image gives you the “depth” of the object or the “z” information of the object in real world.
Let's say you have 100 images in your dataset. So you will require 100 matching images where each pixel represent the distance (depth) of the object from the camera. LERC and MRF are the extensions of the file that we support. You will have to enter the URLs to the depth images in the DepthImg field.
Depth maps can be obtained using stereo camera, triangulation, point cloud, or Lidar data etc.
