nadar Posted October 25, 2013 Report Share Posted October 25, 2013 I'm producing oriented blocks from digital SLR camera combined to a GPS + IMU mems sensor. The aim is to measure trees size (crown diameter and height) for biomass estimation. Image resolution is about 15cm. The blocks are quite small (3-10 images in a single row, with 70% overlap) For one project, it's nearly impossible to obtain accurate GCPs (high density tropical forest), and satellite images are not very good (clouds / haze): I have to rely on GPS / IMU only ("direct georeferencing") The resulting oriented photos (and orthophotos) are quite good and coherent, but are misplaced for 30-50 m. Is there a solution to interactively shift the entire oriented block to better match a reference satellite image, using only one reference point ? I can of course shift the resulting orthos, but then I lose the possibility of 3D analysis. I'm using ERDAS 2013 and ArcGIS 10, with all extensions. Thanks for your suggestions Quote Link to comment Share on other sites More sharing options...
