I know others (and myself) have discussed this topic before but I don't feel that there has been any real solution or explanation as to why it is necessary. What I am talking about is the no data value in DEM export. I have a way of removing the negative values of -32767 from the DEM post-photoscan, but I am interested in finding out if it is possible to get rid of this altogether without having to apply external workflows to the data. I have tried exchanging the -32767 value with other positive numbers, but when opening the raster file in GIS the negative value is always there. Have anyone given this any thought? Alexey, are you guys aware of this?
