    Default Limitation on number of datapoints?

    Is there a limitation on the number of datapoints you can open in global mapper? I have 1.9 million + datapoints.

    You are only limited by available memory. With the 32-bit version of Global Mapper you can usually get to 10-15 million points before hitting memory issues. With the 64-bit version of GM you can go much higher than that even.

    Let me know if I can be of further assistance.

    Thanks,

    Why is it not gridding the values to the west and a portion to the south see attachment. I've checked the master record in another GIS program and it is accurate to the number of data points that fill the extents of these polygons. I am using 32bit Global Mapper.

    How exactly are you generating the attached map? Are you creating an elevation grid from 3D point data or something like that? If so what settings are you using when creating them? If you select the points in the no-data areas do they have elevation values associated with them?

    Thanks,
