Hi, I have been used snap for a while, and I feel this is the best open source remote sensing tool. (another advanced tool is Orfeo ToolBox, which I don't know whether is relevant to SNAP, but seems not that many users and mainly a commandline tool)
In SNAP, I find most image processing related to specific sensors is sufficient , but the mapping and exporting good quality maps may still need some work. As some discussions here and here, and some pending issues already pointed out:
in GPT(or pconvert), it would be good to allow to import vector overlap in anexport map. (e.g., I need to include the lake boundary, with boundary lines but no fill color, to show the area of interest)
the legend and other map elements cannot export together within the map. currently it is difficult to make a useful map, since the exported map has no legend , scale bar, and north arrow, thus not easy to interpret.
ideally it would be the best to let user design a template, and every time just insert a new image and the GPT/pconvert can make a map based on the given template. (this is very useful to make sequence of maps that often needed in satellite image processing.)
thank you all for the effort to provide such a great tool, for free!
