<div dir="ltr">Hi Users,<br><br>I'm having the problem of projecting a source map (landsat 8 image) into a target location (Ordnance Survey UK) in Grass 7. <br><br>I have tried the r.pack/unpack method but i get the following error:-<br><br>'WARNING: Projection information does not match. Proceeding...'<br><br>The resulting view shows both images but the landsat image is many kilometres to the north of where it should overlap. <br>Have also made 'PROJ2'(see below) with the same n,s,e,w as 'PROJ1'(see below) but still the same result as above. <br><br>As i understand it the underlying Landsat images are in the WGS84/lon-lat format. <br>I'm wondering should i use m.proj to first convert the co-ordinates to OrdSurvey? <br><br>I seem to recall just using 'r.proj' in the past with no problems at all but now i get error:-<br><br>'WARNING: pj_transform() failed: latitude or longitude exceeded limits'<br><br>I'm a little confused as to which module to use to get around this problem.<br><br>g.region -b <br>north latitude: 89:59:47.524206N<br>south latitude: 49:45:56.915978N<br>west longitude: 18:03:37.69897W<br>east longitude: 0:02:23.60354W<br>center longitude: 9:03:00.651255W<br>center latitude: 69:52:52.220092N<br><br>'PROJ1' - DEFAULT_WIND<br><br>proj: 99<br>zone: 0<br>north: 5848507.5<br>south: 5605492.5<br>east: 540907.5<br>west: 300892.5<br>cols: 540915<br>rows: 5848815<br>e-w resol: 1<br>n-s resol: 1<br>top: 1.000000000000000<br>bottom: 0.000000000000000<br>cols3: 1<br>rows3: 1<br>depths: 1<br>e-w resol3: 1<br>n-s resol3: 1<br>t-b resol: 1<br><br>'PROJ2' - DEFAULT_WIND<br><br>proj: 99<br>zone: 0<br>north: 1230000<br>south: -123<br>east: 660000<br>west: -66<br>cols: 108220<br>rows: 1169781<br>e-w resol: 5<br>n-s resol: 5<br>top: 1.000000000000000<br>bottom: 0.000000000000000<br>cols3: 10000<br>rows3: 10000<br>depths: 1<br>e-w resol3: 5<br>n-s resol3: 5<br>t-b resol: 1<br><br>Thanks,<br clear="all"><br>-- <br><div class="gmail_signature"><div dir="ltr"><b>Paul J.
