<div>Hi<br> <br>I'm using GRASS GIS 6.4.0 (stable version) in Windows (because my Univ made a few addaptations and modules to be used in my final project) but I'm having some difficulties in using Georectify tool.<br>
<br>After I select 3 points, I press Recalculate RMS Error (and I get the image that I have attached to the email). THis is impossible to have 0,0 as error (in this case). and I got:<br>POINTS file <D:\data\Area\scale\group\ai\POINTS> saved <br>
But, then I press Georectify and It freezed all Interfaces and I got, in the top of each one, (Not Responding)... I waited 10 minutes (it sould take less than that). And still not responding...<br>In the Windows task manager i.rectify is running with 3,420 and Python 47,000<br>
And If I go to my mapset folder I see that the files were created.<br>Is this normal/expected? What might be happening? Because this happened more than once...as a matter of fact, all the times that I tried with these images.<br>
Maybe it has to do with Defined region. My define region must cover source (of course) and also target I suppose. Right? </div>
<div><br>My active mapset is the same as my source image (in order to save the images in the source mapset).<br> <br>Another question:<br>If my source (to be georreferenced) data has a resolution of 10 meters and my target (already georreferenced) as 30 meters resolution and my active mapset is 10 meters.. Georreferenced output will have which spatial resolution?<br>
<br>Thanks<br>Jenny</div>
