Resumo	(*)(?)	This paper aims to evaluate the geometric quality of Quickbird and RapidEye images using accuracy 0,02m ground control point (GCP). The study area is located between the municipalities Belterra and Santarém in state Pará including a small area UC Flona Tapajós. This review was performed to RapidEye and Quickbird images with 0.60m and 5.0m resolutions respectively. The methodological approach followed the steps: Implementation and measurement of the GCPs coordinates; the processing of the observed data; analysis and evaluation of Cartographic Standard of Accuracy (CAS). The methodology that defines a statistical analysis of the planimetric accuracy is composed by the trend and the accuracy analysis. The trend analysis was accomplished using the Student''s-t test with the objective of discover the presence of systematic error in both Cartesian directions. The accuracy analysis was performed using the chi-square statistical test, where sample variances were compared the standard values pre-established by the Brazilian Cartographic Accuracy Standards law. The field data were collected through two surveying realized in August and November of 2013, using static relative positioning, kinematic and stop and go. The surveying resulted samples for geometric image correction and further evaluation needed to study. After application of the methodology, it was observed that the Quickbird and evaluated according to the CAS, in Class B to cartographic document, scale of 1:5000 and smaller and RapidEye was evaluated in Class A cartographic products from 1:25000.
