In fact I have create two folder nlocation and nmapset in the hiberarchy of (nlocation/nmapset),then I start the grass with the gui ,I got the error messgae that I am mot clear?....
1) I want to know the relation of the grassrc file and the contere location or mapset ? Which should be created frist? 2) If I do my process in the gui ,then should I do the g.region process? 3) Some data which can be displayed in the grass gui can not exported perfectly,most of them contains only black blank after exproted.....
