Image to map rectification
Image rectification is a transformation process used to project images onto a common image plane. This process has several degrees of freedom and there are many strategies for transforming images to the common plane.

Witryna20 kwi 2016 · Landsat TM image for eastern Sierra Leone to correct a geometrically distorted image of the same area. Methods Part 1: Image-to-map rectification In the first part of this lab we worked with the Chicago area. We had a raster image that we needed to geometrically correct and a reference image which was a topographic map. WitrynaStep 1: Open an image containing the reference scale. Step 2: Drag the corner markers to the corners of the reference scale. Step 3: Press 'Rectify'. The image will be transformed such that the area within your markers is mapped to the shape of the reference scale, as indicated by the dashed yellow lines. If necessary, reposition the …
