Grid Creation

Data can often be collected in varying densities and spatial patterns.  It can then be used as a point database, a TIN, or converted to a grid.  The following mechanisms can be used for the creation of the grid:

In some cases with a rectangle, there can be two ways to draw the contours, as in the case on the left.  On the left, a ridge connects the two points with elevation of 80, and on the right, a valley connects the two points with elevation 70.  The number of such boxes will generally be small, and with a large DEM, the effect will also be very small.

 

Additional algorithms not used in MICRODEM for grid creation.
