Are you sure he is not altering the coordinate system? I have not experienced this misalignment issue.

Subject: Efficient way to download and use large quantities of MassGIS LiDAR data

 

NEARC-L,

 

One of the people in my lab is wanting to use the newly updated MassGIS LiDAR data as a more precise DEM than the SRTM DEMs. The MassGIS DEMs are available as tiles, however the project my coworker is working on would involve regions of a few dozen tiles or more. While the tiles can be bulk downloaded in OLIVER, he says they aren't aligned with each other when he goes to use them, and it's frustrating to individually load that many tiles.

 

Does anyone know of a smoother way to access a large region of the DEM data? Even better would be if there is a way to access data using a script rather than through the OLIVER GUI.

 

Thanks for your help,

Tracy
