I would like to map microfractures in a sample using ArcGIS.
Available Data: A micrograph of the sample under REM (BSE Mode) in a raster format (.jpeg). The contrast was set in a way that the fractures are easy to see. (Black lines over white grains). The raster is not projected, but the scale is known. How can I project the raster accordingly and set the scale?
Goal of the study: To calculate the number of fractures (approx.) and to construct a map of the space orientation of the fractures in order to get an indication of their source.
There seems to be no clear tutorials or literature discussing this method on the forums and discussion boards on the internet. So I hope I find my answer here. Could someone please guide me through the needed steps. I have basic knowledge of ArcGIS.
