%X The CBERS Program, a partnership between Brazil and China, launched its latest satellite, CBERS-4, on December 7, 2014, being then a new satellite that needs assessments on their performance and on applica-tions for its images. In this study, the images of the MUX sensors, PAN 5 meters and PAN 10 meters belonging to CBERS-4, were evaluated according to PEC Cartographic Accuracy Standard for testing the class which they fit and, then, the users can define their requirements for the product generated. The study area is located in the state of Goias, the capital Goiânia. The images passed through a digital processing to be performed radiometric corrections (correct possible degradations caused by defective sensors calibration, data transmission errors and radiometric influences) and mosaics. For validation, we collected 30 control points, enough points for the sam-ples behavior tends to the normal distribution, using digital orthophoto of Goiânia, considered Class A, for scale 1:5000, as a reference. With the verification, it can be seen that the images of the three sensors are shown as Class B for certain ranges. In the verification, the calculation of the scales, it took into consideration the study that says that the value of EIFOV is aproximately 1.5 times the value of the Nominal Space Resolution of the images.
