I am doing a project for a client in which they want me to take structure locations spread over about 5 miles, add 3D models to each location point and export it to KMZ so they can use it for a Google Earth tour and flythrough for a presentation.
Here is my workflow so far:
Took KMZ (structure location) points from client, imported into Arcmap as a feature class.
Exported feature to DXF
Imported DXF into sketchup (points come in as Cpoints)
Find location in sketchup, and get maps and terrain for the entire project to ensure proper elevation and placement of structures.
Drop cpoints to terrain and grow my structure components from cpoints using Raytracer extension. So, at this point, all structures should theoretically be in their correct place (at least on the x,y plane, the terrain is another story). Verified that structures are in correct place when compared to KMZ from client in Google Earth.
Export 3D model to KMZ.
After opening KMZ in Google Earth, the structures start out in line with where they should be, but by the end of the line, they are at least 50 feet off of where they should be in Google Earth. This is obviously a big problem because the client needs these structures accurately placed. What is going on here?
This image shows where Sketchup says my model is placed (top view parallel projection)
This image shows where the model actually ends up when exported to KMZ. The point labeled 15e is the KMZ point from the client, and the little red dot is the test model (50 feet north of where Sketchup said it would be).
Any ideas on what is happening here? Thanks.
