General / Floating Scene Problem: Can't change vert. datum-"Vertical Datum is Unavailable"

« on: September 11, 2018, 06:43:52 PM »

Hello Agisoft Community!

When I export my .slpk file and import it into ArcGIS Pro, it displays "hovering" above the basemap in the 3D scene layer. 
The Lat and Long axes are correct but the z axis needs adjusted. 

I cannot seem to do this "shift" along the z axis in Arc PRO, so that it will "sit" properly on top of the base map..
So I thought if I change the reference settings before I export, could this move the model along the z axis? 

I fly the DJI Phantom 4 Pro and when I load the photos into PS, I notice that "WGS 84" is the default Coordinate System.

I was able to successfully change the predetermined Geographic Coordinate System from "WGS 84" to "WGS 84 + EGM96 height" and when I did this, it shifted the model from hovering above the base map to sinking below the base map after I changed it.  (See attached Photo)

So I tried to experiment with using other Projected Coordinate Systems such as:
"NAD 83 / Pennsylvania North (ftUS) + NAVD88 (ftUS) (EPSG::8773) and others, but whenever I select these,

I get the following message:

"Selected vertical datum is unavailable.  Please configure datum transformation."

I researched this but I couldn't find how to configure the datum transformation? or how to make this projected coordinate system available so that I can try and fix this problem with the floating scene layer?

I am hung up on this process.  Does anyone have any thoughts about this?

Thank you!

General / Tiled Model Creation - Source option

« on: August 29, 2018, 08:55:45 PM »

 Hello,

Does anyone know what the difference is between creating a tiled model based off of the dense cloud vs. mesh would be? Advantages/Disadvantages?

I understand it would depend on the settings that you set when creating the dense cloud and mesh, but I have been experimenting with both and have not noticed a difference between the end products?  They both look good to me.

Thanks

General / .slpk Export Not Displaying Properly - Missing Pyramids?

« on: August 14, 2018, 05:52:09 PM »

Hello Agisoft Friends,
 
I have been testing the capabilities of Photoscan Pro using the trial license, and am considering buying multiple licenses for my company.  I am very happy with your product, and I find it far superior to all other comparable platforms, however there is one major setback that I hope someone here can help me work around. Then I know I can commit to purchasing licenses.

I work with esri products and I inquired to them about how their platforms read .slpk files. I found that ArcGIS Pro is reading from the contained .jpeg textures, while ArcGIS Online (AGO) is reading the compressed textures from the dds file.

I need the tiled model to be compatible with AGO and their I3s specifications that require compressed textures to contain pyramids.  As far as I can see, the main problem is that the .slpks' associated dds file has the dxt texture file, but is missing the pyramids for the texture, and once the slpk file is created there is no way to create the pyramids after that.
Am I correct?  Is there an option or setting that allows the .slpk export to include pyramids? 
(Please see google drive link to the .slpk file in question and screenshots of the problem below)

It is a situation when I try and add the .slpk file to "My Scene" in AGO .  (See Attachment)

I opened the same file in ArcGis Pro, and was able to view it and it displayed very nicely as a 3D map, however when I load it into AGO the resulting model is very strange looking, built with irregular shaped polygons, and the surface (texture) is a repeating image collage from a section of the model.  The location is correct, the "measure" tool is giving accurate measurements and the shape of features in the model are accurate ( for example the shape of the farm is clearly identifiable: See attachment) so it appears there is no problem with the geographic elements of the file.

Any thoughts?
Is there a foreseeable fix for this?

Thank you for any help and let me know if need more information.
