Berau is a district that has a wealth of natural resources that are abundant and spread across several subdistricts in it, but there is no clear administration boundary makes frequent occurrence of problems in determining the location and position of an object between sub-districts in Berau.In this research, the determination of the boundaries between the four districts in urban areas in Berau are done by using Kartometrik method with reference to Minister Regulation No. 76 Year 2012 on Guidelines Region Emphasis. Kartometrik method is a method to detemine the boundary line and pillar limits of the area using data from satellite imagery. The Satellite images that were used are WorldView-2 imagery and Ikonos and other supporting data such as RBI maps, RTRWK Maps and RDTR Berau Maps.This thesis resulted in the boundaries line on land and the river. The length of the land boundary obtained is 14 833 meters, which restricting the 3 sub-district boundaries, and the length of the boundary line in the river is 25 843 meters showed that restricting 4 sub-district boundary. There is a change for area wide length, the changes occurred in 4 districts on urban areas in Berau. The increasing area length, occurs in two sub-districts, Tanjung Redeb and Teluk Bayur, while the other sub-district as Gunung Tabur and Sambaliung experienced a reduction of area length. This is because the previous boundary line determination is not done by a professional.
