The Interpolation option in the Build DEM window only has the Enabled (default) option when Mesh is selected as the Source data.

For the mesh I wanted to use to create the DEM I had used the Dense cloud option for the Source data, Disabled for the Interpolation option, and Ground for the Point classes. This left holes in the mesh. I ran Smooth Mesh on the result and wanted to test the DEM creation with the smoothed mesh. Since Build DEM only has Enabled for the Interpolation option, the holes in the mesh were filled in the resulting DEM.

When right clicking Orthomosaic in Workspace and selecting Export Orthophotos selected photos become unselected.

It works as expected when selecting  from Tools>Export>Export Orthophotos... pulldown.

Can the color representation of the DEM be exported as an image for use in a GIS?

Hi, I'm hoping you can help me with the vertical datums feature, which will be a huge help.  I have a project referenced in WGS84 Lat/Lng and meters HAE, and would like to export it ideally in a state plane with NAVD88 feet.

I see that when I use the 'Convert' button in the reference pane, and pick the WGS84 + EGM96 geoid height, the z values all change to reasonable geoid heights in meters.  The value of "chunk.crs.wkt" changes to be a COMPD_CS with VERT_CS/VERT_DATUM components that make sense.  However, I can't seem to build my own PhotoScan.CoordinateSystem object with a vertical datum component.  Even trying to create a new CoordinateSystem with the WKT that was chosen automatically fails (with a non-pythonish error in the binding):
Code: [Select]
>>> PhotoScan.CoordinateSystem(PhotoScan.app.document.chunk.crs.wkt)
Traceback (most recent call last):
  File "<console>", line 1, in <module>
SystemError: NULL result without error in PyObject_Call

What I would ideally like to do is build a CoordinateSystem with something like the following, to get state plane data in US Survey Foot units in all three axes, and use it with chunk.exportDem.

Code: [Select]
COMPD_CS["California zone 4 NAVD88 ftUS",
  PROJCS["NAD83(NSRS2007) / California zone 4 (ftUS)",
    GEOGCS["NAD83(NSRS2007)",
        DATUM["NAD83_National_Spatial_Reference_System_2007",
            SPHEROID["GRS 1980",6378137,298.257222101,
                AUTHORITY["EPSG","7019"]],
            TOWGS84[0,0,0,0,0,0,0],
            AUTHORITY["EPSG","6759"]],
        PRIMEM["Greenwich",0,
            AUTHORITY["EPSG","8901"]],
        UNIT["degree",0.01745329251994328,
            AUTHORITY["EPSG","9122"]],
        AUTHORITY["EPSG","4759"]],
    UNIT["US survey foot",0.3048006096012192,
        AUTHORITY["EPSG","9003"]],
    PROJECTION["Lambert_Conformal_Conic_2SP"],
    PARAMETER["standard_parallel_1",37.25],
    PARAMETER["standard_parallel_2",36],
    PARAMETER["latitude_of_origin",35.33333333333334],
    PARAMETER["central_meridian",-119],
    PARAMETER["false_easting",6561666.667],
    PARAMETER["false_northing",1640416.667],
    AUTHORITY["EPSG","3496"],
    AXIS["X",EAST],
    AXIS["Y",NORTH]],
  VERT_CS["EGM96 geoid height",
    VERT_DATUM["EGM96 geoid",2005,
      AUTHORITY["EPSG","5171"]],
    UNIT["US survey foot",0.3048006096012192,
        AUTHORITY["EPSG","9003"]],

]

Hello,
did you change the way the sparse cloud (align photos) is computed.
I achieved better results (less misaligned photos) with 1.1.6 than in 1.2.
Regards,
Mathias

What is difference between DEM from Dense Cloud or Mesh???

It's only saved time?

is there a possibility to toggle between selection mode (rectangle, ellipse, freehand) and navigation mode (arrow). This would made editing much easier. (similar to pressing space bar in Photoshop always toggle to pan mode -very convenient)
Hello nadar,

Have you tried using Space? It should switch between the navigation mode and the last selected selection instrument.

Thanks. Works fine. Will save me loads of time and stress !

Hello bisenberger,

We'll check the hole filling issue regarding the DEM genration from mesh.

As for the orthophotos export from the selected cameras, are you sure that selection isn't discarded when you right-click in the Workspace pane?

Yes, that is when it happens.

Hello Alexey,
I tested the last Photoscan release and I experienced some lag (the display freeze during one second every two seconds approximatively)  in model and photos display.
This appends only after having opened a mesh model, before doing this all was ok.
This is a little bit annoying in big project when you have to navigate between photos or to do selection in cloud model.
May be you can do something to fix it.
Thanks.
Pascal

I notice that while i merge chunks, the Shaded mode disappeared!, and the number of faces is gone!!!!
Is i do some thing wrong?
Thanks

Hello Diego,

Have you checked it after updating to the build 2145? Probably you'll also need to rebuild mesh.
