The use of GPS is now widely used by various parties, especially in determining the position of object location. GPS can be used to measure the land areas, on both wide and flat areas. It can also be used both at night and day, and even it can be used in bad weather conditions. This paper discusses the evaluation of the measurement result of land area using GPS technology compare to the information containing on the land certificate document. The generated GPS coordinates will be converted into units of meter so that length of each side can be known. Heron formula is used to calculate the area of a land plotted on the Google Map. From the series of measurement, GPS measurement fall above the land area expressed in the certificate and bellow the meter tape measurement. This measurement still need to study further to get a stable measurement. But it can be used by public community to show the land location to facilitate the land trading. The limitation that must be considered in using GPS is that GPS signal should not be hindered by any barriers such as leafy trees or tall buildings.
