A map that’s used as a basis to draw the boundary unit of geomorphology is a topography map. Topographic maps depict clearly the different reliefs that appear on the surface of the earth.

A tentative geomorphological map is drawn up early because morphology is the the most easily seen and identified appearance. Morphological changes reflect differences in lithology, geological structure, exogenic process, and time.
Determining process of geomorphology unit boundary can be done with following step:
Determining process of geomorphology unit boundary can be done with following steps:
* Create a boundary line unit by taking into differences in density of contour lines (dense and loose)
* Create a boundary line unit by taking into differences in density of contour lines (dense and loose)
* Make a geomorphological section in certain direction to be certain of the limits of morphological unit
* Make a geomorphological section in certain direction to be certain of the limits of morphological unit
