| Abstract | A novel algorithm to address the reprojection of MODIS level 1B imagery is proposed. The method is based on the simultaneous 2D search of latitude and longitude fields using local gradients. In the case
of MODIS, the gradient search is realized in two steps: inter-segment and intra-segment search, which helps to resolve the discontinuity of the latitude/longitude fields caused by overlap between consecutively scanned MODIS multi-detector image
segments. It can also be applied for reprojection of imagery obtained by single-detector scanning systems, like AVHRR, or pushbroom systems, like MERIS. The structure of the algorithm allows equal efficiency with either the nearest-neighbor or the
bilinear interpolation modes.
