Reconstruction constraints for water - Override the 3D construction

Thanks for that. I wish I could use that but since the body of water splits the project and has multiple crossings I was hoping that I could add an image. I see that you can add a basemap during the reconstruction. I think that might work better. Has anyone tried that? I may just have to revert to editing an obj and remove the creek and then bring in a separate area.

KML for Region of Interest should work in base ContextCapture.

Thanks Ron, but as you can see in my previous post I do not have Context Capture Center. Adding a reconstruction constraint is only available in Context Capture Center.

Hi Sean,

According to the ContextCapture help, you can define the region of interest for reconstruction with a KML file.

Context Capture Help:
If the reconstruction is georeferenced, an extruded polygon can be used to define the area more precisely from a KML file. Click on the button Import from KML to specify the region of interest from a KML file. The KML file only defines a 2D polygon: top and bottom height can be defined from the interface.

If you define the KML to avoid the water area it would leave that area out of the reconstruction. You could then create a seperate surface to fill the water area void and apply an appropriate material to it so it looks like water.

Regards,
Ron

Hi Sean,

This video is showing how to add a constraint : https://www.youtube.com/watch?v=SkG7RmVpvxc.

For the third party software I would recommend you to use MicroStation or ContextCapture Editor to create the .obj file.

HTH,

Mathieu

What is the best source to use for this? Would a polygon clip from a geo-reference image work?

Ok. I do not have Context Capture Center so I cannot use a kml from Google Earth. Can I use a polygon from a geo-referenced image? I am just not real sure of the workflow.

Hi Sean,

I think leo means to create a polygon for the water area and add that polygon as Terrain constraints to ContextCapture.

What do you mean by digitize? I guess I am asking digitize from where?

Digitize and add the water area as Terrain constrains before reconstruct mesh..!!
