There are some void spots in my generated matrix, can this be fixed ?
There are two causes for voids in the matrix data.
The first one has something to do with the color ranges. When certain points are outside the range of the color table, they are just not drawn. Select "Matrix Colors..." from the "Options" menu to adjust the color ranges.
This also happens when the distance between surveyed lines is more then 20 meters. In this case the software thinks the distance is to great to calculate reliable results. The best is to use 10 meter as maximum spacing between survey lines.
