What metadata is needed to use measurement tools in Oriented Imagery Viewer?

TadasBernotas — Thu, 02 Apr 2020 12:27:25 GMT

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,

Tadas

Do you get the solution about this?

Hi Tadas,

To activate measurement tool in the viewer, you will need to define the Accuracy field in the Exposure Points feature service.

You can get more detail about the accuracy parameter and how it can be defined from this documentation.

Documentation Link - oriented-imagery/OrientedImageryCatalog_Schema.pdf at master · Esri/oriented-imagery · GitHub

Also, here is the snippet

You can put dummy value for Accuracy field - 0.5,0.5,1,1,1,1,1,1 to quickly test the measurement capability.

You can also define the Accuracy in OIC (See below)

{"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": "0.5,0.5,1,1,1,1,1,1", "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"}}

Thank You.

Will I modify Accuracy using a property tool without recreate features

coverage, coverage map and publish?

Should I put values like this?

Yes. Enter the Accuracy field value here.

Re: What metadata is needed to use measurement tools in Oriented Imagery Viewer?

SoukainaMENJEL — Wed, 30 Sep 2020 08:14:59 GMT

After that, will I just re-publish the catalog or re-run Feature coverage

and coverage map?

Another question, I see that you make OIType: T, and when I see my

properties I found that it was a B Type.

What's the types of OIC? and is it necessary to make the type T?

For the accuracy value I put : 0.1,0.1,0.1,0.1,0.1,0.1,0.1

And it shows me that the widget is added. Location and height works but

distance and area cannot, as you see,doesn't be clicked.

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

Anonymous User — Wed, 30 Sep 2020 16:47:15 GMT

No. It depends on what type of image you have. It is defined in this document - oriented-imagery/OrientedImageryCatalog_Schema.pdf at master · Esri/oriented-imagery · GitHub

Re: What metadata is needed to use measurement tools in Oriented Imagery Viewer?

SoukainaMENJEL — Thu, 01 Oct 2020 08:59:00 GMT

As I understand it, should I add a column named depthImg in the CSV that I

add in 'add images to oriened imagery catalog' or just add it at the

attribute table ?

I have images with jpg extension, what is the definition that I can add to

the depthImg field? such that i tried with JPEG, JPG and PNG and it

doesn't work.

You can define it in CSV or just add to the attribute table also. Both approaches should work.

For depth images, the extensions we support are LERC and MRF.

Re: What metadata is needed to use measurement tools in Oriented Imagery Viewer?

SoukainaMENJEL — Thu, 01 Oct 2020 22:36:31 GMT

So add in attribute table a field named DepthImg and put MRF or LERC in all

cases? That's it? And add the same value in depthImg property?

Another question, if what i say is correct, i will re-publish the catalog

directly or will i re run the feature coverage and coverage map?

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.

SoukainaMENJEL — Fri, 02 Oct 2020 10:57:25 GMT

hi,

So what i did is:

1. I add column depth images in exposure points's attribute table. I put

LERC in all fields/cases, and also in depth Image field in OIC Properties.

doesn't work

2. I deleted just LERC from OIC Properties (Depth img field). doesn't work

3. I deleted the column from exposure points's table, and I put LERC in OIC

Properties. doesn't work

I do the same steps with MRF, and i get the same result like using LERC, no

widget was added in oriented imagery Viewer, and the widget of measurement

doesn't show.

So, I re-try again, and this time I re-run the accuracy, the widget of

measurement is shown.

but distance and area cannot be clicked.

How can I solve this?

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.

I don't have Z information, so what?

Can you send me an exemple of how to insert information of depth image?
