| 14:41:39 | jcarlsen: | I am completely new to arial photography, but is very curious about how to make it work |
| 14:42:02 | jcarlsen: | I've found out that I need to orthorectify the images I've taken |
| 14:42:17 | jcarlsen: | and so far it seems like GRASS is the program to use for it ( on Linux ) |
| 14:43:23 | jcarlsen: | the pictures I've taken is oblique ( I think its called ), is there any good guides on how to orthorectify such images? |
| 14:45:41 | jcarlsen: | the pictures I've taken look something like this: ( far from perfect ) |
| 14:45:45 | jcarlsen: | http://jrc.wenix.dk/jrc/IMG_6354.JPG |
| 14:49:55 | jcarlsen: | hmm, reading about it - I get the idea that this is not as simple as I thought it would be |
| 14:50:48 | jcarlsen: | I thought I could more or less just mark some reference point on the image, and I would mostly be done |
| 14:50:59 | jcarlsen: | points, that is |
| 15:09:27 | wildintellect: | with obliques you have to know the angle relative to NADIR ( straight down ) |
| 15:14:00 | wildintellect: | jcarlsen, http://books.google.com/books?id=BtR0Mxp0HBYC&pg=PA266&lpg=PA266&dq=GRASS+GIS+processing+oblique+air+photos&source=bl&ots=gbreKD0vlT&sig=2CGDJZ56yD6Od0PhqYVqAOrK2j4&hl=en&ei=QYMIS9mrGJPkswPEsJjBCQ&sa=X&oi=book_result&ct=result&resnum=2&ved=0CA4Q6AEwAQ#v=onepage&q=&f=false |

| 15:14:21 | wildintellect: | the problem is that section was removed from the new edition to make room for more common techniques |
| 15:26:32 | wildintellect: | its very similar to processing regular air photos with the added parameter at the beginning of the angle of the camera |
| 15:46:19 | jcarlsen: | wildintellect: thanks, I'll take a look |
