I'm a new to GIS and I need some help.At the moment, I'm trying to develop an optimal path across an area by using GRASS 7 features. It is very similar to the task given here. The problem is that I don't have any data with elevation points and cost surface for this area. Tell me please, how can I create a raster with the cells showing low-high travel costs and how can I set an elevetion points?
Thank you for your time!
