2012 Map3D Surface Generation

247 Views, 2 Replies

If anyone can help,

 

I have created a point cloud and surface from LiDAR data.  The point cloud data was relatively large from what I am familiar with (approximately 30 GB all told), and ESRI ASC surface file (approximately 8 GB) was generated after a laborious wait.  However, when I attempt to add the ASC file as a raster to view the surface, MAP 3D crashes and loses connection with my PC (ie window freezes, and I have to force MAP 3D to shutdown).  My computer is fairly updated with quad core processor, 3 GB RAM, etc.  Is this not enough power to process such a large image file, or have I errored?

 

Any help would be greatly appreciated.

 

Sincerely,

 

Kevin

3 gigs might not be enough

what does the task manager say as far as memory usage for map when you are doing this?

The task manager window almost instantaneously shows Map as not responding, and memory usage is typically 400,000k+.  It had no issue actually generating the surface, albeit slow, it still was capable of generating.  Just the adding to map phase is a no go.
