Cesium 3D tiles - Coordinate Shift
« on: February 22, 2018, 08:33:45 PM »
I processed a drone flight, using a state plane coordinate system (US FT) and exported the tiled mesh to Cesium 3d Tiles. Upon loading the tiles into the cesium developer environment, I needed to perform an extreme shift to the tiles for them to line up with the orthoimagery. Did the shift occur due to the State Plane system not converting to ECEF well?

For reference: the data is to be in SW Indiana, but was showing up on the border of Arkansas and Missouri necessitating a coordinate array shift of [295340.9598075826, -4949134.996101385, 3998961.3828470935].

Hello Peter,

Can you please provide the PRJ file with the coordinate system definition that you are using and approximate area of the project (for example, the coordinates of one camera in the project or one of the markers used for georeferencing).
