Dear ER-MAPPERS: I have nearly 150 photos and I would like to
scanning, rectify, georefrence and glue (mosaic) them to make one rasterized image covering all the area. (These photos are very old and I haven't
information about the elevation and camera's properties), Meanwhile I have a
DEM covering all the area , Also I have ER-mapper
6.1. I have gotten serous confuse with this work. First there are tow questions: 1) Are there any logical relationship between the (dpi)
during scanning and the actual pixel size of scanned aerial photo? And how can I Understand
the actual size of scanned aerial photo? 2) What are
the minimum characteristics of aerial photo (camera's parameters) to use georef
orthogeoref? Please show me
if there was similar subject or other general information regards all the idea.
Thanks in advance
