This thesis describes the work of Global Positioning System, it's developed the android application using information retrieved from such a system allows each user an average quality measure land surface. In just start it is described type of ways and forms in which the GPS information found to be a very important source of information. Starting from ordinary measuring length, height and guidance to specialized machines while performing different types of activities (agriculture, construction, computing). In further embodiments, described is the principle of use the GPS sensor in the Android "smartphones", which means the GPS coordinates allow users to use GPS in everyday needs (navigation, discovery of important institutions, buildings, etc.). The principle of using the realized applications "PovrsinaGPS" is described in the fourth chapter describes the user guide as how to properly use the application. Below is an analysis of the application itself through measurements in different areas of measurement. Through the analysis it was found that the applications their future application can be found mostly in the area of largescale measurements of land (about 2400 m2 and above) with measurement error up to 10% as the agricultural and processing operations does not matter the size. When measuring small areas error occurs due to the inaccuracy of the basic forms of GPS which is not so exact, while the measurement of the populated area that is an area in the vicinity there are plenty of leafy trees or buildings there is a large error of 24%. Interference measurements for the environment can be best seen in the application window "Google Map", which graphically illustrates the measured area. The graphical representation of visible anomalies that do not follow the actual display satellite images of the area measurements. The application would provide better results if is in the device inside a DGPS (Differential GPS) that provides information to the centimeter accuracy with the help of base stations that are on the earth's surface with a much higher price of the device. But the price is still a condition that should not be neglected, and also the sense of making these applications ported because today's mobile devices, "smart phones" on the market with built-in basic GPS sensor.
