There are different methods for geometric correction of NOAA AVHRRdata

but these methods pay less attention to the accuracy

or are technical complex

almost unsuitable for most users.When combining AVHRR data with other highresolution satellite data

or with precise ancillary data

it is necessary to develop aaccurate geometric correction method

which should be easy to use for non- profes-sional users.After analyzing the pixel shape and size of AVHRR data along scan line andevaluating the quality of geographic data within NOAA AVHRR 1B data set

it isclear that the geographic data have a very high accuracy for identify the pixel sizeand shape.The proposed method has two steps.The first step is the correction of distortedpixel.The separate program performs the distortion correction

applying the geog-raphic data of AVHRR 1B data set to assign the value of each pixel of the desiredoutput geographical area with given pixel size

and doing logical judgment for un- assigned pixels.The second step is the conventional polynomial transformation.An application of this method is presented

in which AVHRR data are integra- ted over multi-temporal data and 1∶50

000 river map with half-pixel accuracy.
