00:00:11 <artem> jburgess: I was thinking about providing stream based interface
00:01:00 <artem> would be one way to address this ( I meant)
00:02:55 <artem> something like : template <typename Stream> load_map( Stream & in, ...)
00:05:00 <jburgess> That would be a better solution but it looked more difficult to setup than xmlCtxtReadMemory()
00:06:04 <artem> jburgess: yes, I realised this.
00:06:10 <jburgess> I think that is enough for tonight.
00:06:26 <artem> yep, got to catch some sleep :)

01:43:51 <scruggs> I'm reading http://wiki.openstreetmap.org/wiki/Mapnik and from that it seems that mapnik can render from shapefiles without using postgis... is that correct?
01:43:51 <nikq> http://trac.mapnik.org/wiki/postgis
01:45:38 <scruggs> I'm guessing nikq is a bot, but the page it sent is not found :)
01:47:33 *** migurski (n=migurski@h-68-165-1-62.snvacaid.covad.net) has joined #mapnik
01:57:34 <Mrfos> scruggs, yes mapnik can render quite easily with postgis
01:57:34 <nikq> http://trac.mapnik.org/wiki/postgis
01:58:36 <scruggs> no, I'm looking to use mapnik *without* postgis
01:58:37 <nikq> http://trac.mapnik.org/wiki/postgis
01:59:01 <Mrfos> ah. yes that works as well. you simply provide the path to the shapefile
01:59:20 <scruggs> great!
01:59:37 <scruggs> is there any documentation to that effect?
01:59:58 <scruggs> everything I'm finding deals with postgis
01:59:58 <nikq> http://trac.mapnik.org/wiki/postgis
02:00:38 <Mrfos> http://trac.mapnik.org/wiki/XMLGettingStarted
02:01:01 * scruggs is taking a look
02:21:11 <scruggs> Mrfos: that helps a lot
02:21:34 <scruggs> is it possible to do the same thing in C rather than python?
02:25:15 <Mrfos> yes, mapnik comes with a fairly nice example showing a candian road render i think
02:25:24 <Mrfos> i dont have much experience dealing with the C++ side
02:26:29 <scruggs> so that's part of the svn sources?
02:26:54 <Mrfos> yep
02:28:41 <scruggs> cool. sounds like its time to checkout some source code :)
02:28:49 <scruggs> thx for the help!
02:28:56 <Mrfos> np
02:29:45 <Mrfos> a pure XML solution might be enough
02:30:34 <scruggs> can you do that without any python?
02:30:56 * scruggs should really investigate the sources...
02:30:56 <Mrfos> mapnik + tilecache + openlayers works well if you're using a common projection and and doing web mapping
02:31:30 <scruggs> I'm trying to target an embedded system so resources are at a premium
02:31:33 <Mrfos> yeah. basically theres a number of existing applications that will take a mapnik xml file and export into various image formats
02:32:31 <Mrfos> are you shooting for a slippy style map like google maps?
02:33:15 <scruggs> I have some self-written code currently that will read/render shapefiles with libgd but the labeling and prettiness of mapnik's rendering has caught my eye :)
02:33:41 <scruggs> yes, but in a GTK app rather than a browser
02:34:45 <Mrfos> and how about how the maps will be served? client/server on the same machine, or through the internet?
02:35:12 <scruggs> same machine ideally...
02:35:46 <scruggs> currently the device can serve the maps via a socket or send the data via stdout
02:36:11 <scruggs> so my app uses pipes to just call the map generation prog and get the data
02:36:26 <Mrfos> well rendering with mapnik can be pretty intensive
02:36:36 <scruggs> the idea is to have it be self-sufficient
02:36:59 <scruggs> how intensive?  :)
02:37:15 <scruggs> if you can put measure to it that is...
02:38:49 <Mrfos> largely depends on how complicated of a map it is. real time rendering could easily bring a quadcore box to a grind
02:39:12 <Mrfos> at least for something complicated like a reading openstreetmap
02:39:25 <Mrfos> *rendering openstreetmap
02:39:49 <scruggs> I see...
02:40:23 <Mrfos> someone here may have better experience using mapnik as a client
02:40:43 <Mrfos> but in most cases mapnik images are pre-rendered then servered to a client
02:40:50 <Mrfos> *served
02:41:19 <scruggs> that makes sense
02:41:46 <scruggs> for some background on my project...
02:42:13 <scruggs> my app is targeted to a 800x600 display and gets fix data from gpsd
02:42:58 <scruggs> it requests a map that is essentially 3x the display size, and just re-centers that larger map pixbuf into the display
02:44:01 <scruggs> once the fix gets within a certain threshold of the edge of the display it triggers a thread to render a new map, and when that map is needed it gets loaded, the pixbuf is re-centered, and the process moves forward
02:45:09 <Mrfos> hmmm
02:45:14 <scruggs> I'm working with contour line shapefiles, so there are lots of lines to go through, but in most cases there is enough time to get a new map rendered before it is needed
02:45:42 <scruggs> rendered maps are saved, so a map isn't rendered if its already there
02:45:44 <Mrfos> well i know GpsDrive is similar and can use mapnik
02:46:10 *** weizhuo (n=chatzill@nat/yahoo/x-dd2d70d2fff89c67) has joined #mapnik
02:46:14 <scruggs> the concept is similar to GpsDrive, just a bit more lightweight
02:46:20 <Mrfos> i see
02:46:55 <Mrfos> well i dont know how well mapnik would work on an embedded system. i pretty much deal with the exact opposite kind of system
02:47:18 <scruggs> in the past my biggest obstacle was rendering labels... lots of floating-point math to figure positions
02:47:29 <scruggs> :)
02:49:00 <scruggs> yeah, if I could have it my way the device would have GPRS or the like to fetch maps, but right now thats not an option
02:49:30 <scruggs> I might just give it a shot and see how the performance is
02:49:54 <scruggs> do you know if anyone has run mapnik on an ARM?
02:50:45 <Mrfos> hmm, dont recall seeing anyone who has
02:51:09 <Mrfos> mapserver might be better suited for an embedded machine
02:52:26 <Mrfos> you could always just install mapnik, and create a simple xml file, and render that to an image
02:52:37 <Mrfos> and see how it runs on embedded machien
02:53:05 <scruggs> thats my thought too... no hurt in trying
03:18:27 <Mrfos> anyone have experience dealing with overlapping line geometry? at a small scale everything is perfect, but as I zoom out everythin gets mashed together?
03:19:21 <Mrfos> short of creating a unique set of geometry for each scale i use

22:02:16 <cmarqu> How do I easiest create tiles from a cascadenik style? All this customize-mapnik-map stuff is pretty confusing.
22:45:50 *** migurski (n=migurski@h-68-165-1-62.snvacaid.covad.net) has joined #mapnik
23:01:57 <cmarqu> migurski: Hi! I just managed to render an OSM map using cascadenik. I'll add some instructions to http://wiki.openstreetmap.org/wiki/Cascadenik
23:02:15 <migurski> oh cool!
23:02:35 <migurski> thanks, that's great
23:03:41 <cmarqu> migurski: Eventually, I'm trying to produce something like http://opentiles.com/nop/?zoom=15&lat=50.96013&lon=14.10922&layers=B, just nicer.
23:05:12 <migurski> with the hills and everything?
23:05:45 <cmarqu> migurski: I hope so, yes. Possibly without the isolines
23:05:46 <migurski> Nop's map is pretty sweet
23:06:54 <cmarqu> It has lots of useful details, but the appearance could be improved.
23:07:17 <migurski> maybe add some hue to the gray background
23:08:15 <cmarqu> For instance. It's also too dark IMO
23:08:55 <cmarqu> The reference for that area would be something like http://boehmwanderkarten.de/kv/is_mssg.html
23:10:40 <cmarqu> migurski: You don't happen to have uncommitted changes to Cascadenik's openstreetmap style, do you?
23:11:03 <migurski> I think I have one ... why do you ask?
23:11:10 <migurski> I believe it has to do with cemetery and park pattern fills
23:12:09 <cmarqu> migurski: I'm going to use it as a basis for my style, and I wouldn't want to use an outdated one.
23:12:16 <migurski> oh I see, yeah
23:12:22 <migurski> well why don't I commit my final change
23:13:48 <migurski> all done: http://code.google.com/p/mapnik-utils/source/detail?r=487
23:14:15 <cmarqu> Based on your experience, should I first try to set up the hillshading and then go on with the style development, or does it work to do it on a "flat" map?
23:15:03 <migurski> I did them sort of separately
23:15:12 <migurski> I did style development first
23:15:25 <migurski> had a complete style all finished, "style.mml" in the repository
23:15:45 <migurski> then I did the hill shading, rendering it all out to its own tile set as just grayscale hills with no other data
23:16:13 <migurski> then I figured out how to split style.mml into figure.mml and ground.mml, and wrote some python post-processing code to sandwich them together
23:16:34 <migurski> I didn't have the best of luck with the RasterSymbolizer, possibly because I didn't understand how it works
23:16:34 <nikq> http://trac.mapnik.org/wiki/RasterSymbolizer
23:17:12 <migurski> also I was being a stickler about transfer modes: I wanted the hills to be overlaid on the ground with something like photoshop's Hard Light filter
23:17:12 <nikq> http://trac.mapnik.org/wiki/filter
23:17:54 <migurski> supposedly on the way for mapnik 0.6 though! http://trac.mapnik.org/ticket/157
23:18:17 <cmarqu> Aha!
23:18:42 <migurski> I know artem has taken some preliminary stabs at transfer modes
23:19:11 <migurski> just first steps from what I can tell, but they look good and he's chosen a wider range of modes than the five I thought would be worth doing
23:19:20 <cmarqu> So... say I'm starting with a flat map. Which mml file would I best take now?
23:19:58 <migurski> do you want to use RasterSymbolizer?
23:19:58 <nikq> http://trac.mapnik.org/wiki/RasterSymbolizer
23:20:01 <migurski> you do okay
23:20:06 <migurski> yeah start with style.mm
23:20:08 <migurski> *mml
23:20:22 <migurski> and slip the raster layer in there
23:20:30 <cmarqu> I don't know yet. I have just started with Mapnik today :)
23:20:39 <migurski> the figure and ground ones are intended to be rendered separately and later sandwiched
23:20:42 <migurski> ha, welcome
23:20:45 <cmarqu> Ah, I see.
23:21:58 <migurski> back soon, phone call
23:56:03 <cmarqu> migurski: Oh, you already introduced a "prominence" tag, or am I all mixed up?
