Dear List,<br>I am new user for Grass GIS. I have some questions regarding Jpg or tiff import. When I use r.in.gdal which created 3 separate files as rgb. Then I use r.patch to combine rgb. After that i.point and i.rectify. From this i have to digitize river, stream, road, etc. So my question is as follow:<br>
Can i remove unrectified former 3 seperate rgb files?<br>Is there any module to import without creating rgb because this increase the memory usage? I have to import more than hundreds of scanned Jpg, tiff.<br>Can i crop the imported image without using other image software such as gimp or photoshop, etc?<br>
Thanks for any hint<br clear="all"><br>-- <br>-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-<br>U Kyaw Moe Aung, Staff Officer<br>Planning & Statistics Division, Forest Department, Director General's Office<br>Nay Pyi Taw, Ph:095-67-405016, Fax: 095-67-405016<br>
