Feature Requests / Export Model in .LAS
« on: May 20, 2021, 08:53:09 PM »
Would be nice to be able to export Model in colored .LAS format (without face).

Python and Java API / importshape and export in dxf
« on: April 18, 2021, 11:51:36 AM »

I'm beginner in python.
I'm looking for a script that can :
1) import all shape files in .shp located in the selected chunk in the location : C:\ImportShape\
2) export all shape in .dxf files of the selected chunk there: C:\ExportDXF\

Could someone help ?

Feature Requests / Re: Shapes on pictures
« on: March 06, 2021, 10:12:49 AM »
In fact, this features are already available!

But 2 others features would be good:
- to be able to export picture with shape on it
- to be able to "drap" shape (without Z value) into the MNS, given a z value to shapes and markers.


Feature Requests / Filter selection Tie Point
« on: March 05, 2021, 12:09:23 AM »
It would be nice a feature that able user to filter by selection the Tie Point. The aim of this feature is to help user to delete some points without deleting goods points.. it is very hard to do this manually, for example for moving trees in aerial photogrammetry.
-Firstly user can filter the selected area around the area where there are false points.
-then user can delete bad points without risking to delete points that are filtered.
- finally, user car reset filter, and the result is: bad points are removed, the rest is still there.

Feature Requests / Shapes on pictures

At the moment, only markers appears on picture.
It would be a nice feature if shapes also appears into pictures !
Drawing directly on pictures would also be great!

Do you think this feature is possible?

Feature Requests / Re: Measurement in VIEWER
« on: February 16, 2021, 10:57:48 AM »
Hi Alexey,
thanks for keeping update ! features of measuring / displaying is very important for us.
We need: profile , slopes, distance 2D 3D for our customers.
Another point we would need is a "basic" way to digitilize / export (using the same SCR)  some layers of vectors drawing using Viewers.
The point is: our customer need solution to use (without knowledge) quickly DEM/Orthophoto/3D/LAS.

Please continue to keep us informed about any feature you add (and you plan to add) for displaying/measuring with Desktop Viewer and Cloud Viewer.
At the moment, the features we need are still not implanted.

Bug Reports / Re: Vertical Datum out of range 1.7.1

Maybe the problem come from another source: I've changed both my Marker and project that was in the old custom GEOID by the new one. Maybe I should only change the project coordinate system without changing the marker and then create DEM?

Thanks Paulo for the help,

When I change my marker + my project coordinate system for the new one, yes I'm able to create DEM & to export it  but I also lost 10cm accuracy into my checkpoint/gcps unfortunatly

It seems I will have to create DEM using another soft and them import it again to perform the orthophoto :-(

Hey Alexey,
thanks for this answer.

If I understand well, I can either create a DEM without using Point Cloud (which is not possible in my case, since I need to filtering many things before like water), or expand the geoid file?
I think I have to expend the Geoid file.
About expending the geoid file, can you explain how can I do that? Can I use Agisoft for this task? the only field where I see  "No data value" is when I've already built a DEM (in another Coordinate system) and I try to export it then I can see this value: -32767, can I change something there?

Edit: I can also see this field when I import GEOID and the same data is fill: -32768

Hi Paulo,
This approach is good if you only fly in NADIR?
I use to fly a false Nadir (80-85) in order to get more detail.
What should I use to do?

Do the same trick you did 2 times in order to get a calibration parametter reusable for next flights. Then, separate each flight in 2 camera calibration group (one for 85 and the other for 80) and then apply the matching camera calibration parametter?
And every time I change the pitch angle I should previoulsy have determinated the calibration parametter for this angle?

Thanks for following my case.

I've did some tries:
-export .LAS with this GEOID works
-export mesh in .PLY with this GEOID works
-building DEM from Tie point with this GEOID : works
-building DEM from Point Cloud with this GEOID: doesn't work
-exporting DEM (built in another GEOID) in this GEOID: doesn't work

I've send you a wetransfer with datas you've asked.
Let me know

Hi guys,
Thanks for help.
Thanks Paul, I've spent a lot of time trying many solutions.. The problem appears for me when Building DEM with this coordinate system or when trying to export a DEM with this coordinate system.
I get some negativ Z value into my .LAS.
Alexey, I've tried to convert my pictures into this coordinate system.
Everything has the same now (picture/project/marker) no one is out of range, and it still doesn't work.

an option to select point by altitude (range) could be usefull to fix this issue or be able to set Z minimum when building DEM.
