Hi @jsaayman and @Pointdump
Both the ECW image and the LAZ points were evaluated in Global Mapper. The projection used in Global Mapper was UTM84-35S, meters.
LAZ points:
The points are projected to Transverse Mercator, Hartebeesthoek 1994 datum with NORTH orientation, meters.
ECW imagery:
The image is projected to Transverse Mercator, Hartebeesthoek 1994 datum with SOUTH orientation, meters. The south orientation is the issue and needs to be changed. See image-1.
Image-1. Global Mapper has both North and South orientations of the Transverse Mercator.
When the ECW's projection is changed from south to north the ECW inserts correctly. See image-2.
Image-2. Note: World Imagery is shown in the background for reference.
The LAZ point cloud is projected correctly. It's using Transverse Mercator, Hartebeesthoek 1994 (north orientation), meters or EPSG 2052. No modifications to the projection are needed so it inserts correctly against GloMap's UTM84-35S coord assignment. Once the ECW's projection is corrected, it can be inserted along with the LAZ points. See image-3.
Image-3. Both the ECW image and LAZ point are inserted . the background is world Imagery.
Additional notes:
- Couldn't index the LAZ points in Recap, it hangs at 75%.
- Couldn't add the ECW imagery to C3D using a data connection.
- Couldn't add the ECW image to C3D using MAPIINSERT.
- The image has an irregular shape. I would suggest cropping it smaller and making it a rectangle. AutoCAD doesn't like irregular shapes.
- South Africa coordinate systems are whacky. Is it possible to get someone (or something) to re-project the points to another coordinate system. I would recomment a world coordinate system such as WGS84.PseudoMercator, meters (EPSG 3857)?
