chen yanjin — Thu, 23 Dec 2021 05:07:12 GMT

Hi All,

I would really appreciate if someone can guild me along with the process of data sets from terrestrial scanner and Drone.

This is my workflow, however I have no luck in getting them to align perfectly.

In Same Block

1.Add some Tie Points to Aerial Photos(RTK) only

2.Add some Tie Points to DSLR Photos only

3.Add 3 ground control points(WGS84 COOR.) to Aerial Photos only

4.Aerotrangulation the block

-Adjustment constraints :Photo position

-Final rigid registration : Control Points

5.Import point cloud .e57(Georef. in svy21)

6.Summit construction

I also tried Aerotriangulation after importing point cloud,using but the errors was too big.

-Adjustment constraints :Photo position

-Final rigid registration : Point cloud

Could anybody help me in getting the right workflow

But the worker engine can run the master engine task,anyone knows whats the issues?

Master Engine

Worker engine

Both engine has same directory and worker engine is able to access the files from master computer.

Any help will be appreciated.

Hi,

I'm looking for SGEOID09 geoid model in. gtx format in order to custom add that height grid in CC.

Anyone know where to get the geoid model from? Or perhaps using ggf or gdf? or other methods which can do so.

Thanks.
