| 12:53:53 | tbnorth: | hi all - I'm looking for a python way to calc distance between two lat/long pairs, preferably osgeo.osr, but if that's wrong whatever's right :- ) |
| 12:54:31 | tbnorth: | actually whatever has the smallest dependency footprint would be best |
| 12:57:10 | mloskot: | tbnorth: a few minutes and you can have your own |

| 12:58:11 | tbnorth: | mloskot: thanks - if I have to re-invent the wheel I'll use that link. |
| 12:58:32 | mloskot: | tbnorth: it's not reinventing, it's writing down well-known equations |
| 12:59:06 | mloskot: | if you buy a book like geometry algorithms do you expect to have CD with implementation of all of them in all popular languages? |
| 12:59:14 | tbnorth: | ok, I'll have a look, thanks. |
| 12:59:23 | mloskot: | no, you just write rewrite them in your favorite language |
| 12:59:57 | mloskot: | tbnorth: anyways, another option is to use projection.py module from Thuban |
| 12:59:59 | tbnorth: | no - but I figure this must be something people are doing all the time - maybe I don't understand the domain of osgeo.osr well enough, but I thought maybe it could do it. |
| 13:00:02 | mloskot: | it has no dependencies |
| 13:00:16 | mloskot: | It used to be available on hobu's website, which now is down |
| 13:00:18 | mloskot: | but you can find it here |

| 13:00:45 | mloskot: | hmm, my bad, sorry |
| 13:00:53 | tbnorth: | I think that failed to compile for me, unless I'm thinking of another one |
| 13:00:54 | mloskot: | I forgot there was no distance calculation AFAIK |

| 13:04:58 | mloskot: | tbnorth: depends on accuracy you need |
| 13:05:57 | wildintellect: | tbnorth, you might be able to re-use code from one of the qgis plugins |
| 13:06:16 | : | * TylerM can't remember if ossimplanet has a ruler |
| 13:07:12 | nhv: | yes |
| 13:08:09 | wildintellect: | tbnorth, ah distance in ftools relies on qgis core |
| 13:08:17 | TylerM: | i knew there was a reason i love it nhv : ) |
| 13:09:12 | nhv: | there is a Python implementation of vincenity's geod and inverse in python somewhere on the web |
| 13:09:17 | wildintellect: | you could also rpy2 into R and use the spDistN1 tool which handles projections etc for you |
| 13:09:27 | tbnorth: | wildintellect: ok, thanks for the idea though. mloskot: thanks too, I think I can find something now. I had already googled quite a bit. |
| 13:09:37 | nhv: | and there is pyproj |
| 13:09:56 | mloskot: | geodjango guys have something too, I'msure |
| 13:09:58 | TylerM: | epifanio: got an easy way to plot points from a list in ossimplanet yet? ;- ) |
| 13:10:28 | wildintellect: | I'm starting to wonder if shapely has stuff like this |
| 13:10:29 | tbnorth: | I guess it was pyproj that didn't compile for me, not http://hobu.biz/software/pyprojection |
| 13:10:50 | wildintellect: | hmm, you could do it all in spatialite with a python wrapper sending the sql |
| 13:10:55 | epifanio: | hi TylerM , you means plot placemark ? |
| 13:11:41 | tbnorth: | spatialite - as in spatial for sqlite? Didn't know there was such a thing, that would be perfect, seeing I'm already using sqlite. |

| 13:13:35 | TylerM: | epifanio: yes |
| 13:13:38 | TylerM: | just curious |
| 13:15:46 | epifanio: | not yet, i need to have a better knowledge about the ossimplanet xml api, ( there is a java example in the souce i need to study it ) |
| 13:15:54 | epifanio: | for now i'm working on the grass-side noe done a good progress to syncronize grass region and ossimplanet scene |
| 13:16:03 | wildintellect: | tbnorth, yup you can run sql SELECT DISTANCE( a,b ) |
| 13:16:50 | tbnorth: | wildintellect: yep - it's looking great for my project - I've used postgis a reasonable amount, but didn't want that big a dependency for this project - thanks a bunch for the pointer :- ) |
| 13:18:28 | epifanio: | in the last week the ossim-dev-team has added a nice enanchments, add "placemark" using the qt gui-menu |
| 13:18:51 | epifanio: | i'll llok in that direction |
| 13:19:08 | TylerM: | ah great! |
| 13:19:48 | TylerM: | tbnorth: I thought you could use Python GDAL libraries with GEOS support for doing it, but haven't done it myself. |
| 13:20:29 | wildintellect: | oh you probably can, since spatialite uses geos too |
| 13:20:38 | tbnorth: | TylerM: maybe, I was looking for geos in osr, but perhaps I'm looking in the wrong place |
| 13:20:47 | epifanio: | cooll spatialite, now qgis has it inside its core, so we can use "internal spatialite" |

| 13:38:43 | jasonbirch: | Anybody know if there's an EPSG code for the projection shown in the KML spec? I've always used 4326, but apparently that's not 100% correct. |
| 13:39:19 | wildintellect: | you have a link to the spec you're refering to |
| 13:39:43 | jasonbirch: | https://portal.opengeospatial.org/files/?artifact_id=27810 |
| 13:39:50 | sigq: | Title: OGC License Agreement ( at portal.opengeospatial.org ) |
| 13:39:54 | jasonbirch: | Warning, invalid SSL cert, and click-through |
| 13:41:06 | wildintellect: | jasonbirch, what page? |
| 13:41:17 | jasonbirch: | Right at the end I think. Just a sec... |
| 13:41:30 | jasonbirch: | 231-232 |
| 13:47:33 | wildintellect: | hmm for 2D data 4326 seems right |
| 13:47:49 | wildintellect: | for 3D data it's modified by 5773 for vertical |
| 13:49:07 | pramsey: | why don't you think it's 4326? |
| 13:49:23 | jasonbirch: | Because they defined a new projection in the Spec? |
| 13:49:24 | wildintellect: | jasonbirch, pages 14-23 attempt to explain what's going on |
| 13:49:38 | jasonbirch: | Yeah, and I attempted to understand : ) ( and failed ) |
| 13:49:58 | wildintellect: | it looks like they modified 4326, by saying that Z values are in 5773 |
| 13:50:16 | wildintellect: | but x,y is still 4326 |
| 13:50:42 | jasonbirch: | So, if my data has a Z, will only the Z be inaccurate? : ) |
| 13:54:43 | jasonbirch: | I don't know a lot about this stuff, but was worried about the vertical datum re-defining the centre of the earth, and wondering if this would cause shifts in the other dimensions. |
| 13:58:43 | wildintellect: | ya I'm a little lost too, but it looks like they're using ogc urn naming |
| 13:58:51 | wildintellect: | I just looked up wgs 84 would be urn:ogc:def:crs:OGC:1.3:CRS84 |
| 14:01:52 | wildintellect: | apparently there are revised versions of wgs 84, so 4978 cir 2006 or 4979 cir 2007 are also basically the same thing |
| 14:07:09 | jasonbirch: | Heh. Thanks for looking at it anyway. I'll just keep using the current projection until someone complains : ) |
| 14:07:14 | milovanderlinden: | jasonbirch: 5773 is a geoid. 4326 only defines a spheroid.. http://spatialreference.org/ref/epsg/5773/html/ |
| 14:07:16 | sigq: | Title: Projection 5773 -- Spatial Reference ( at spatialreference.org ) |
| 14:07:51 | jasonbirch: | milovanderlinden: does that affect horizontal coordinates? |
| 14:07:53 | milovanderlinden: | 5773 only tells height is gravity related and in meters positive |
| 14:08:15 | milovanderlinden: | are your coordinates retrieved with GPS? |
| 14:08:19 | milovanderlinden: | then it will not |
| 14:08:29 | jasonbirch: | Typically retrieved by survey |
| 14:09:08 | milovanderlinden: | survey by "waterpassing"( sorry; don't know the english word ) from known points? |

| 14:10:22 | milovanderlinden: | lol |
| 14:11:19 | milovanderlinden: | I believe gps assumes the world to be a perfect globe. All heights in gps coords are relative to the center of the reference globe |
| 14:11:27 | milovanderlinden: | but I may be wrong |
| 14:13:43 | milovanderlinden: | http://en.wikipedia.org/wiki/WGS84 states: |
| 14:13:44 | sigq: | Title: World Geodetic System - Wikipedia, the free encyclopedia ( at en.wikipedia.org ) |
| 14:13:45 | milovanderlinden: | Presently WGS 84 uses the 1996 Earth Gravitational Model ( EGM96 ) geoid, revised in 2004. This geoid defines the nominal "sea level" surface by means of a spherical harmonics series of degree 360 ( which provides about 100 km horizontal resolution ) |
| 14:14:07 | milovanderlinden: | so, nothing changes at all. |
