The field work using image data as the main composisition for making spatial data information. The image data be processed first so that the position of a point on the image appropriate to the actual position of the field. This processing takes a known reference point coordinates in the global reference system called Ground Control Point (GCP). To determine the coordinates of the GCP should be observed using Global Positioning System receivers (GPS). GCP observation on the field work used the radial method that conducted simultaneously in four villages (Sugeng Village, Jatijejer Village, Sukosari Village and Cembor Village) with a base in each villages which is Sugeng at SG 1, Jatijejer Village at SK 6, Sukosari Village SK 2 and Cembor Village CB 6, Trawas District. After the observation, data is processed to obtain the coordinates of GCP and then perform image rectification. Results from GPS measurements and rectification is a map with the distribution of GCP in Jatijejer village. During the process of obtaining the coordinates of GCP till the presentation of data required some supporting software. Supporting software include PC – CDU to download data from GPS receiver, Topcon Tools and GPS tools for data processing of GPS observations, ER Mapper for image rectification that is part of geometric correction and cropping image data, as well as Autodesk Land Desktop 2009 for the data presentation. From observation, we can conclude that there are mean RMS which is Valued 0.664 pixel and Mean Standard Deviation which is valued 0.002 m. Keywords : Ground Control Point (GCP), GPS, Rectification

using image data as the main composisition for making spatial data information. The image data be
processed first so that the position of a point on the image appropriate to the actual position of the
field. This processing takes a known reference point coordinates in the global reference system called
Ground Control Point (GCP). To determine the coordinates of the GCP should be observed using
Global Positioning System receivers (GPS). GCP observation on the field work used the radial
method that conducted simultaneously in four villages (Sugeng Village, Jatijejer Village, Sukosari
