Elevation was recorded as the z value. Simple Text was used because Surface III can read that format with out translation problems. It then asked for the number of rows and columns. It was important to choose floating point because the z-matrix of elevation consisted of decimal numbers. If fixed point was chosen the decimals would not have been able to be read in causing the program to not recognize the data.
Higher elevations have a brighter signature and lower elevations a darker signature.
To fix the problem, the grid size for the z-matrix and base map was reduced by half. Resized Base Map Average was used because the numbers in the base map were fixed point. The grid size was then recalculated. This time when it asked for the number of rows and columns, I put in the size of the resized base map. The soil coverage was made off of the base map using Map Factory.
