01:08:44 amalon: darkblue_B: no i haven't really worked with tiff in programming before
01:09:22 amalon: TylerM: thanks for the tip, I'll look into GDAL. is there documentation for it available online, i can't see any links to it in trac?
01:21:09 yjacolin: amalon: the doc is on gdal.org
01:26:35 amalon: yjacolin: oh right, it looks from here like the site is down
01:27:27 amalon: thanks, i'll try again later
01:29:24 yjacolin: yes gdal.orgt seems down
01:29:40 amalon: : ) google cache did the trick
01:29:56 yjacolin: amalon: do you speak french ? if so there is a french translation outsite gdal.org :p
01:31:53 amalon: yjacolin: heh, a bit not well enough
01:32:25 yjacolin: bad luck, so you need to wait ; )

04:59:53 gpotts: hello all, I was wondering if anyone knew where one could download the latest BigTiff
05:00:01 gpotts: I can't get to the cvs tree for some reason
05:00:19 gpotts: and was wondering if there was a tarball for the latest src cvs
05:04:41 jmckenna: gpotts: http://www.asmail.be/msg0054797451.html
05:04:43 sigq: Title: LibTiff Mailing List Archive, "Libtiff CVS Tree Moved", by Frank Warmerdam ( at www.asmail.be )
05:04:59 gpotts: ah
05:05:01 gpotts: shott
05:05:04 gpotts: shoot
05:05:12 gpotts: thanx a million
06:04:30 darkblue_B: ajturner: kml printing?
06:07:38 crschmidt: darkblue_B: I wonder sometimes if someone gave you a book of my IRC pet peeves as an instruction guide or something : )
06:08:14 crschmidt: I guess you only really hit 2 of the 4 on http://trac.openlayers.org/wiki/IRCPoliteness , so it must have been an incomplete book : )
06:08:15 sigq: Title: IRCPoliteness - OpenLayers - Trac ( at trac.openlayers.org )
06:15:01 darkblue_B: yesterday ajturner asked about kml printing, so I cobbled up a demo using libkml and pdflib, in python, as a proof of concept. neat, eh?
06:16:05 crschmidt: cool; is the code somewhere that other people can check out?
06:16:51 darkblue_B: not yet.. but it certainly has the makings of something pretty useful
06:16:59 darkblue_B: the *idea* does
06:17:22 : * crschmidt loks forward to seeing the code
06:17:51 crschmidt: Could use it for a proof of concept for something myself
06:18:54 darkblue_B: I thought of OL right away actually... some of the guts in a complete solution has to do some similar things
06:19:41 crschmidt: Well, getting a PDF out of something like OpenLayers is exceptionally difficult, but the code in OL is typically a well-maintained and generally easy to read example of how to read geodata and interact with it in pixelspace
06:19:49 crschmidt: which can be useful for taking geodata and putting it into a PDF as well
06:20:03 crschmidt: My proof of concept would be unrelated to OL though : )
06:20:25 crschmidt: I've got a longstanding low priority request to do more interesting things with getting MetaCarta search results onto paper
06:20:34 darkblue_B: y, parallel worlds of course.. but the code decomposition might be instructive
06:20:53 darkblue_B: results -> paper.. exactly
06:21:01 crschmidt: Since we have KML APIs with styling information, KML->PDF would be one interesting possibility
06:21:23 crschmidt: If you want an svn repo to toss it in, i've got one handy i can give you write access to *shrug*
06:21:40 darkblue_B: the philosophy is, to me, KML is like the PowerPoint of Geo
06:22:05 crschmidt: Yeah; I've said HTML of Geo, bu Powerpoint is probably a better analogy
06:22:31 crschmidt: almost no information delivered, where it's all about the presentation : )
06:22:49 darkblue_B: I have a lot of work on the day job.. the ogr bindings topic, and this would be third
06:23:05 crschmidt: ogr bindings topic?
06:23:32 crschmidt: I haven't seen any evidence that using libkml within OGR's kml parser is worthwhile
06:23:43 darkblue_B: but since ajturner is so much in the spotlight right now, I thought there might be another angle for this print hack to mature
06:23:57 crschmidt: well, I'd gladly take and run with it with code
06:24:08 crschmidt: but if you're not able to share, such is life, I suppose
06:24:33 darkblue_B: ogr - I've said before, there are substantial benefits, and an opportunity right now, but, lack of resources...
06:24:55 crschmidt: Well, you've said there are substantial benefits
06:25:13 crschmidt: but I offered a rebuttal to that, and didn't see a response
06:25:16 darkblue_B: share - thats a taunt ... of course its shareable, its only a few hours old and not nearly clear enough
06:26:21 ajturner: hey darkblue_B
06:26:23 ajturner: yeah, checking it out
06:26:28 darkblue_B: rebuttal - there was a huge electric car announcement yesterday here, and a minor emergency on my recycling network regarding the coming carbon markets
06:26:49 darkblue_B: .. so I am getting whiplash
06:27:01 crschmidt: well, my comment was about 6 weeks ago : )
06:27:07 crschmidt: so maybe there was something more recent on the mailing list I missed
06:27:21 crschmidt: E_TOOMUCHTRAVEL
06:27:24 darkblue_B: I have not been keeping up with the mailing list
06:27:35 crschmidt: Oh. I'm cnfused then, sorry
06:27:35 darkblue_B: ?
06:28:11 darkblue_B: well ajturner is here now.. maybe we can talk about the print hack
06:28:32 darkblue_B: it is a good thing.. it would be great to have in the community
06:29:00 darkblue_B: .. its just potentially a lot of features to hammer out, to do it well
06:29:37 ajturner: of course, TerraGo would *love* you to support KML -> GeoPDF : )
06:29:50 darkblue_B: I wrote postscript professionally for many years
06:30:06 crschmidt: ajturner: Heh, we had that conversation with them at one piont
06:30:13 ajturner: yeah, me too
06:30:16 crschmidt: we gave up when they started talking about charging us to do geopdf
06:30:21 ajturner: they need a coupla tix for the cluetrain
06:30:37 crschmidt: "Wait. You want to sell your technology by charging content producers?"
06:30:38 ajturner: for us they just said "yeah, we only do custom solutions, an engine'd be great"
06:30:46 ajturner: and "here's the OGC spec" - which is pretty empty
06:31:43 ajturner: for print - can also pull up AStraup's or my PocketMap code ( PHP and Ruby resp. )
06:32:18 darkblue_B: AStraup ?
06:32:19 ajturner: ah, darkblue_B the large difficulty here with KML is the styling information - right now just rendering point geometries
06:32:25 ajturner: Aaron Straup Cope of Flickr
06:32:27 darkblue_B: yeah!
06:32:44 darkblue_B: proof of concept ;- )
06:32:49 darkblue_B: needs a lot
06:34:10 ajturner: Kml lib is nice - does it handle figuring out feature-level styling?
06:34:16 ajturner: the semi-cascading ?
06:34:57 darkblue_B: I havent tested the read results much, its very new itself
06:35:03 darkblue_B: they had been changing it
06:35:21 darkblue_B: just a few weeks agao they said dont bother looking at theparse resutls too much because they will change
06:35:34 darkblue_B: I'm using a trunk build
06:36:17 ajturner: hrm
06:36:30 darkblue_B: I know how to write out colors and icons and such to postscript/pdf
06:36:41 darkblue_B: but inevitably it will be a lot of work
06:37:13 ajturner: yep
06:37:20 ajturner: it's the KML cascading that becomes a little more difficult
06:37:26 ajturner: and also things like icons & hotspots
06:37:39 darkblue_B: cascading? maybe I dont follow
06:37:47 crschmidt: darkblue_B: styles can inherit fro meach other
06:37:58 crschmidt: and features can have styles explicitly and inherit from other style definitions
06:38:02 darkblue_B: yes.. but I assume libkml will deal with that
06:38:11 ajturner: and you can override Document-level styling with Placemark level stying
06:38:11 crschmidt: Well, I think that's what ajturner's question was
06:38:17 darkblue_B: the parse result will be static
06:50:24 darkblue_B: I just searched the headers, it appears that they dont have a getExtent( ) on the KML .. thats not too good
14:04:12 : * tomkralidis is excited to hear about a C code sprint in his backyard
