Python and Java API / Re: ExportDEM as an XYZ file

« on: December 12, 2017, 09:15:16 PM »

Sorted Alexey,

My/our mistake. When we upgraded to 1.3.4 it was linking to the old install or 1.3.1 and I never checked the version I was running was ACTUALLY 1.3.4.

As you said in 1.3.4 the xyz export performs as expected.

Thank you for your help

Kind Regards

Dave

Good Morning Alexey,

I've tried specifying just the path as

Code: [Select]

DEMFile = "%s/DEM.xyz" %resultsFolder
chunk.exportDEM(path = DEMFile)
but I then get:

RuntimeError: Unsupported extension: .xyz

Any thoughts or workarounds?

Thankyou in advance

Dave

Quick update.

Our IT support have just updated me to 1.3.4 but I'm still experiencing the same behaviour

Hi Alexey,

Firstly a correction on my behalf I'm using V 1.3.1 (Build 4030). I can't easily upgrade to 1.3.4 as I run photoscan pro on a remote system without root access.

A more detailed example of the code I'm running is:

if forceGeoRef: PhotoScan.app.document.chunk.transform.matrix = PhotoScan.app.document.chunk.transform.matrix

DEMFile = "%s/DEM.xyz" %resultsFolder
if exportDEM:
   DEMregion = (math.floor(chunk.elevation.left),math.floor(chunk.elevation.bottom),math.ceil(chunk.elevation.right),math.ceil(chunk.elevation.top))
   DEMres = math.ceil(100*chunk.elevation.resolution)/100.0
   chunk.exportDem(path=DEMFile, format=PhotoScan.RasterFormat.RasterFormatXYZ, projection = chunk.crs, region = DEMregion, dx = DEMres, dy = DEMres)

With various inputs I get the following errors:

RuntimeError: Unsupported raster transform
RuntimeError: Unsupported extension: .xyz
RuntimeError: Unsupported datum transformation

See consol dump below for more details...

I haven't checked rigorously but it doesn't seem to matter whther I've generated the DEM planer or geographic.

Any thoughts would be much appreciated...

Kind Regards

Dave

Python and Java API / ExportDEM as an XYZ file

« on: December 11, 2017, 05:35:35 PM »

Quick questoin that's been driving me crazy all weekend. From the GUI (V1.3.0) it's possible to export an elevation model as an *.xyz file that defines the surface on a grid as a series of readable points. In local coordinates a typical file output would look like this:

-4.5657   3.0712   -21.344
-4.1664   3.0712   -21.330
-4.1093   3.0712   -21.330
-4.0523   3.0712   -21.330
-3.5389   3.0712   -21.373
-3.4818   3.0712   -21.373 etc etc

However I can't work out how (if it's supported) to setup the exportDEM() function to achieve the same result.

The closest I get is:

2017-12-11 13:28:19 Traceback (most recent call last):
2017-12-11 13:28:19   File "/panfs/panasas01/ifac/jf13928/JOBS/171130_162506/settings/getDem_002.py", line 56, in <module>
2017-12-11 13:28:19     chunk.exportDem(path=DEMFile, format=PhotoScan.RasterFormat.RasterFormatXYZ, projection = chunk.crs, region = DEMregion, dx = DEMres, dy = DEMres)
2017-12-11 13:28:19 RuntimeError: Unsupported raster transform

From this code:

chunk.exportDem(path=DEMFile, format=PhotoScan.RasterFormat.RasterFormatTiles, projection = chunk.crs, region = DEMregion, dx = DEMres, dy = DEMres)

I've tried countless combinations of settings in chunk.exportDem(...)

Is this even possible or am i missing a trick?

Kind Regards

Dave
