How to Even Out Relief Data Array Using Spline Surfaces
Depicting territory relief while creating topographic maps and plans faces a problem how to even out the initial data of altitude marks received with the help of GPS measurements or the available DEM model of NASA. The above-mentioned data adaptation is a matter of necessity because initial information contains measurement errors that appreciably distort relief or even depict the real surface altitudes under research insuffi ciently on small scale. This task is accomplished in the article by using spline surfaces in Excel.
