By expanding the application of the Global Positioning System (GPS), this method became increasingly inexpensive, light and easy. The accuracy of the GPS was improved, and apparently, the constant control of the morphological changes on the surface of the earth altered slowly and modestly. The purpose of the study is to measure morphology of ditches in a pond near Loyd in the Shankxi province using GPS. there are three main types of ditches within the area of study: the side ditches, valley ditches, hill slope ditches. This research focuses mainly on ditches of the hill slopes. The ditches of the slope in the research area are largely discontinuous and develop rapidly. In the area of research, the density of the ditch is very large. The regress rate of the slopes of the hill is 0.16-2.0m per year. The relationship between the drainage area with high slope (A) and the main slope (S) of the ditches of hill slopes is S = 0.1839 A. The 2AS values in the main cuttings of the hill slope ditches are in a range of 41 to 814 square meters and most of them range from 100 to 300 square meters. Both of these relationships are considered as indicators of the position of the ditch’s main cutting.

“Geography is the science of places”, “Geography is the science of connections”, “Geography is the science of human ecology”, “Geography is the science of dispersion”, and “Geography is the science of mutual relations”... are all the beautiful definitions of geography that have been expressed by the great scientists of this science, such as Vidal de La Blache, Griffith Taylor, etc. Each of the above definitions, while in the simplest form of expression, has certain complexities, which, after stating causes of various factors, has established the foundations of geography, and has been interpreted by geographic associations all over the world, and has been the founder of many thoughts and ideas that made a significant contribution to the advancement of geography in the world, so that in addition to the advancement of this beautiful human knowledge, it caused certain followers each explain the old ways and try to contribute to the progress of thoughts through critique and evaluation. However, from another perspective, the abovementioned scholars were not only the founders of a new tradition, but also helped their followers in their respective countries and in other countries to benefit from it and promote their thoughts, especially in their country, and this fact has been developing the science of geography in these countries and providing the ground for scientific advancement and other aspects of domination over the world both scientifically and colonially. In this paper, we try to recognize our share in geography and to know what geographic dominant ideas exist in our country? Or, with what point of view, a better and more appropriate thought can be chosen for the geography of Iran. With a brief look at geography in Iran, we will find that this science, along with the progress of other sciences in the world of Islam, was properly cultivated during this period, and the scholars of the Balkh and Iraqi schools, each with their own interpretations, made significant contributions to the flourishing of this era, even by writing the geography through pilgrimage literature.
