![]() ![]() IrfanView is the first Windows® graphics viewer. A powerful graphics viewer, designed from scratch to be simple for beginners and powerful for professionals. Arcview can orthorectify photos with a DEM and RPCs,but I'm not sure offhand how you'd go about generating a set of RPCs for an arbitrary digital camera. Download IrfanView a fast, compact, small and free image viewer and converter that will work on almost all Microsoft® Windows® versions (including XP, Vista,7,8 and latest version 10). ![]() GRASS GIS would be the place to start on that sort of project. The release comes with new features, including a new image comparison option. I've not used it myself, but once you get the coordinates and filename into a CSV you can do some simple geoprocessing inside Arcview to create your point feature class.įor the latter, you need to calibrate the camera / lens system, use a DEM to correct for terrain displacement, and have a highly accurate IMU for good georeferencing (a few degrees of pitch and roll can make a big difference in the photo footprint, depending on your optics). 17 IrfanView 4.60 is the first release of the image viewer in 2022. ![]() 2) Options -> Multipage images -> Create Multipage PDF -> Add images (1 pdf of 3Mo and 16 pages) Its works I obtain 1 pdf with 16 pages and 1,25Mo. There are two ways to do that : 1) File -> Save as -> Type -> PDF - Portable Document Format. I'd do it as a shell script with exif and OGR doing the heavy lifting, but that's not exactly userfriendly if you aren't familiar with command-line software. I followed Mij advice and do a manual and single convert PDF to PDF. extract the GPS coordinates of the photo series, add the heading as an attribute (extrapolating from the other positions in the series if the GPS heading isn't in the EXIF), and export to a shapefile. I would like to also point you to some advice. Realistically though, if you edit a JPEG file just once, and re-save as JPEG with 100 quality, then to your eyes, you will almost surely never perceive any quality loss. The former is relatively straightforward. If you want to save it without losing any quality, then the only way to do it is to save using a lossless image file format. Do you just want to extract the GPS coordinates as a point feature? Or do you want to try to georeference the jpegs for viewing directly in ArcView? ![]()
