2017-03-27 Thread Bulent Arikan
Dear List, I have two separate questions for Grass 7.0, which has been running on Mac OS 10.10.5 Yosemite: 1) My project encompasses three UTM zones (35-36-37 in northern hemisphere). About 80% of the area falls within UTM 36, 15% in UTM 37, and 5% in UTM 35. I know that in principle, each GRA
