| 10:34.56 | cr2 | kiozen: excellent program :) i've referenced a picture with 75 GCPs yesterday. just for fun. |
| 10:35.39 | kiozen | cr2: well say thank you to gdal. GT is just a humble frontend |
| 10:35.53 | kiozen | you ever tried a really distorted map |
| 10:35.58 | kiozen | ? |
| 10:36.19 | cr2 | it was not distorted |
| 10:37.02 | cr2 | i've "auto"created the GCPs with names and coordinates. with awk |
| 10:37.07 | *** part/#htc-linux swc-666 (n=no@24.143.67.18) |
| 10:37.15 | kiozen | maybe I try this weekend with a paper map scanned without closed and weighted lid |
| 10:37.23 | cr2 | and then just moved then into the right places. |
| 10:38.32 | kiozen | but good to know that gdal digests such an amount of gcps :) |
| 10:38.59 | cr2 | the biggest problem was to push the GCPs into the picture bounding box |
| 10:39.15 | cr2 | 75 is not much. |
| 10:39.47 | cr2 | it's 6x6 or 9x9 linear system after all |
| 10:40.15 | cr2 | TPS will need much more resources. |
| 10:40.48 | cr2 | another nice to have feature is "delete all gcps" |
| 10:41.15 | cr2 | does the incremental gcp loading work ? |
| 10:43.29 | kiozen | should work |
| 10:43.33 | cr2 | i've also thought about the direct ozi .map loader |
| 10:43.35 | cr2 | ok |
| 10:43.57 | kiozen | yes I have to implement strg+a and del |
| 10:44.53 | kiozen | with ozi I would prefer the same as with mph/mpr -> an external converte |
| 10:44.55 | cr2 | the addRef should not be void, but return refpoint * |
| 10:45.42 | cr2 | kiozen: ok. but then it's probably easier to add the gcps to .tiff directly. |
| 10:45.43 | kiozen | what for? |
| 10:46.13 | cr2 | btw, you may check if the gcps are already present in the .tiff, and draw them. |
| 10:46.31 | cr2 | in the .ozf2 -> .tiff converter. |
| 10:46.48 | kiozen | yes that's somewhere on the TODO stack |
| 10:47.00 | cr2 | ok. |
| 10:47.44 | kiozen | but for what would you need refpoint * addRef() ? |
| 10:47.54 | cr2 | if i'll understand ozi datum -> epsg conversion, then the gcps will be easy to do. |
| 10:48.10 | cr2 | it will simplify the code |
| 10:48.24 | cr2 | <PROTECTED> |
| 10:50.20 | cr2 | the gcp loader ignores negative pixel coordinates, but will happily accept those outside the bounding box. |
| 10:51.28 | cr2 | it's ok in general, but not very useful in other cases. |
| 10:52.16 | kiozen | bad regex at line 219 :) |
| 10:53.22 | cr2 | when you "autogenerate" the gcps, both cases may be interesting. |
| 10:53.44 | kiozen | svn up (untested) |
| 10:53.55 | cr2 | the transform itself does not care where are the gcps. |
| 10:54.02 | cr2 | ok. |
| 10:54.22 | cr2 | but with the names gcps you may want to position then inside the bbox :) |
| 10:54.29 | cr2 | s/names/named/ |
| 10:54.55 | cr2 | to match what you see in the bbox. |
| 10:56.05 | cr2 | 'Del' the highlighted gcp is also good. |
| 10:57.00 | cr2 | filename.*Latin1() should be probably filename.*Local8Bit() |
| 10:57.25 | cr2 | just a braindump from yesterday' night. |
| 10:58.12 | cr2 | yeah, the program is certainly the on its way to world domination (tm) :) |

| 21:20.14 | cr2 | i've one more idea. mark some gcps as 'corner markers', so they are just defining the rectangular bbox, and not used as gcps. |
| 21:20.56 | cr2 | it's trivial to cut the outside margins with just an gdal_translate parameter. |
| 21:21.33 | kiozen | well we could do extra cut marks |

| 21:22.35 | cr2 | yes, if there is only junk in the margins. |
| 21:23.06 | cr2 | but if you have the coordinate grid, you lose all the numbers, and need to keep a gimp window opened at a side |

| 21:37.05 | kiozen | not really |
| 21:37.46 | cr2 | well, these are minor differences. 1mm :) |

| 21:38.47 | kiozen | it's impossible to scan two sheets exactly on the pixel |
| 21:39.09 | kiozen | thus you have to cut a few pixel. leading to whit estripes |
| 21:39.24 | cr2 | don't they overlap ? |
| 21:40.05 | cr2 | ah. you cut the big map. |
| 21:40.05 | kiozen | they can't if you cut 1 map |
| 21:40.12 | cr2 | ok :) |
| 21:40.57 | kiozen | I think I will spare the 2nd map for a better scanner |
| 21:41.00 | cr2 | get an A3 300dpi scanner, like i've done. |
| 21:41.14 | kiozen | a2 or a1 would be better |
| 21:41.24 | cr2 | too much €€€ |
| 21:41.52 | kiozen | not to buy, better to do this with a scan service |
| 21:42.01 | kiozen | the problem is just to find one |
| 21:42.14 | cr2 | kiozen: btw, filename.*Utf8() will probably break on mac/win |
| 21:42.39 | cr2 | ok. i've never heard of such service, actually. |
| 21:42.53 | cr2 | A4 and A3 is never a problem. |
| 21:43.26 | cr2 | kiozen: qgis uses filename.*Local8Bit() |
| 21:44.12 | kiozen | ok |
| 21:56.23 | BabelO | lol, i just understand why last day pH5 says : installed scratchbox (urgh) |
| 21:59.27 | cr2 | BabelO: too simple for you ? |
| 22:00.18 | BabelO | cr2: yes a bit crazy even with the automatics install script |

| 23:18.10 | BabelO | cr2: any quick idea about cp parameters to keep symlink and others strange file ? |
| 23:24.17 | cr2 | BabelO: cp -a ? |
| 23:26.18 | BabelO | cr2: i just try with cp -R -p |
| 23:26.34 | BabelO | ok your is better ;) |
