Output of georeferenced data

Hello there,

I am trying to achieve a workflow for the correct export of georeferenced data (pointcloud, surface model, orthophoto).

So far I have not managed to output anything I could work with, so I want to ask for some help here:

In a simple sample project, I have aerial images with standard GPS coordinates, Ground control points in UTM33N > converted to GPS.

So what I did is setup the project & output coordinate systems according to the system used in the images and ground control points. After export I have the following problems:

xyz cloud:

The coordinates don’t make sense to me. It looks like a local system but somewhat weird:

0.217106 0.894019 117.158782
0.217108 0.894019 117.158653
0.217107 0.894020 117.183854
0.217107 0.894023 116.707789
0.217105 0.894025 117.031059

Only the height (Z) is correct.

digital surface model & orthophoto:

On the first try, my GIS application QGIS 2.18 immediately crashed upon trying to import the TIFs. So I calculated a new component from scratch.
On the second attempt, I get a weird repetition of the selected region. Again, only the altitudes seem to be correct.

I have made a couple of screenshots which I can hopefully attach below.

Any help would be greatly appreciated. I need to get this right if I want to use RC for commercial projects later on.

Best regards,
Bodo

Hi Bodo S.

Its possible to get the data used here or even better to take a remote access session ? its probably just a setting issue…

Problem solved by exporting in proper COORDINATE SYSTEM ( Not WGS84 )

Good mornig, i from peru and i speak english a Little. I have the same problema in the last versión. Here there isn´t “Coordinate System” ….can you help me???

Do you mean by here, in Peru?  If so, here is a list of coordinate systems used in Peru:

1.- I start programa with Coordinate Systems 5387 Peru96/UTM Zone 18S in:  Project Coordinate System and Output Coordinate System  (3.jpg)

 

2.- Pictures have Lat/long

3.- When proceded Ortophoto coordinate system is epsg:4326 - GPS (WGS 84)  (not coordinate Project system)  (1.jpg)

4.- Digital Surface Model export in epsg:4326 - GPS (WGS 84) (2.jpg y 4.jpg)

this pictures are a fast example

the ouput coordinate are latitud and longitud and not UTM…i need UTM

Hi Achoque,

I think you can fix it by expanding the “Info” box in the “Ortho Projection Tool” panel. Right at the top of the expanded list it will say  “Coordinate system”. Could you check those settings if they match up with your desired coordinate system?
