11:10 #navit: < alex____> hi there
11:12 #navit: < CarPCMan> hi
11:18 #navit: < alex____> today is a map day, will continue soon with mapdiffs.
11:18 #navit: < alex____> btw, i have an issue with map display, will leave it here
11:25 #navit: < alex____> http://imgur.com/a/J3441 land and water color the same, but not always. am i wrong with settings (using mostly defaults one) ?

12:34 #navit: < jandegr> hi kazer
12:35 #navit: < jandegr> in case you don't know where the mountains are

13:13 #navit: < KaZeR> jandegr: wow really nice
13:13 #navit: < KaZeR> that's especially useful when biking
13:14 #navit: < KaZeR> this is worth a tweet or post or something
13:15 #navit: < jandegr> I will try to resolve a remaining bug in the heightprofile view in gui_internal
13:17 #navit: < KaZeR> sweet. really nice jandegr
13:17 #navit: < KaZeR> i'll look into the details of the job you linked to build a worldwide map. Then I'll look into a new mapserver to host it
13:21 #navit: < jandegr> circle did only the last step, download data and convert to OSM with Srtm2Osm was done locally
13:21 #navit: < KaZeR> yeah i was looking at it. i see the download from your dropbox for example
13:22 #navit: < KaZeR> you did the Srtm2Osm locally on only a subset of the map right?
13:22 #navit: < jandegr> yes
13:23 #navit: < jandegr> took quite a few attempts to get it right :)
13:24 #navit: < KaZeR> ah. would you mind sharing more details? i can look into processing the world map
13:24 #navit: < jandegr> to produce CA-incomplete as in the link to circle ..
13:25 #navit: < jandegr> provide data beforehand, or join Nasa for on the fly download
13:25 #navit: < jandegr> and then
13:26 #navit: < jandegr> srtm2osm -bounds1 37 -123 39 -118 -cat 400 100 -large -firstnodeid 54000000000 -firstwayid 54000000000 -maxwaynodes 1999
13:27 #navit: < jandegr> then have coffe while it converts part of CA from Srtm to OSM
13:28 #navit: < KaZeR> eh, link from the announcement is dead : http://srtm.usgs.gov/index.html
13:29 #navit: < jandegr> 4. Srtm2osm downloads the needed *.hgt DEM information automatically from Nasa to subfolder srtm/srtmcache if not specified differently. Nasa data is however not very good in mountaineous regions. On viewfinderpanoramas.org you can get much better DEM data. Head over there and download all availble 3" DEM for the region you need (you know the coordinaties from step 2). Place them into subfolder srtm/srtmcache of you srtm2osm installati

13:30 #navit: < KaZeR> thanks
13:30 #navit: < jandegr> http://www.viewfinderpanoramas.org/Coverage%20map%20viewfinderpanoramas_org3.htm
13:30 #navit: < jandegr> is where I got mine :)
13:31 #navit: < jandegr> but I did have a working link to Nasa as well,
13:32 #navit: < KaZeR> thanks that's already a good start

13:34 #navit: < KaZeR> alex____: http://imgur.com/a/J3441 looks like a known issue regarding map data conversion. Where did you get your map from?
13:35 #navit: < jandegr> not tested, page takes ages to load, but who knows you can get the entire planet with a script from there
13:35 #navit: < alex____> KaZeR it was generated by maptool from osm data
13:35 #navit: < jandegr> (is still about Nasa :)

13:37 #navit: < robertp> salut!
13:37 #navit: < alex____> hi
13:42 #navit: < KaZeR> salut robertp !
13:42 #navit: < KaZeR> alex____: you did the processing yourself?
13:44 #navit: < KaZeR> if so, that explains it. You probably had an open contour in the map you processed, so the water front "flooded" the inside of your map. To avoid that you need to use a smaller map (to avoid the open waterfront) or you need to use a much bigger source map (to ensure that the contour is closed)
13:44 #navit: < jandegr> or he has 2 built@home maps loaded
13:44 #navit: < jandegr> flooding each other
13:45 #navit: < alex____> but that's a problem
13:46 #navit: < KaZeR> it is indeed
13:46 #navit: < jandegr> no, that is a "known issue" :)
13:46 #navit: < KaZeR> well, that's a tricky one to solve
13:47 #navit: < jandegr> alex____ have you tweaked maptool or the data in some way ?
13:47 #navit: < jandegr> if not, downloading from the mapserver is the best option,
13:48 #navit: < jandegr> and then multiple maps don't flood each other
13:49 #navit: < alex____> i've used osm maps from geofabrik, and it was maptool without any patches
13:49 #navit: < jandegr> kazer do we need depthlines as well for those flooded maps ?
13:50 #navit: < jandegr> alex then why build@home ?
13:50 #navit: < KaZeR> jandegr: i think that depthlines everywhere would be nice. And if it's flooded maybe it'll help us fund a dry spot up high on the mountains :o)
13:51 #navit: < alex____> jandegr it was an expiriment to test how mapserver approach works with queues
13:51 #navit: < jandegr> ah ok
13:51 #navit: < KaZeR> jandegr: well i understand that people could want to build maps by themselves
13:51 #navit: < jandegr> oh really ?
13:51 #navit: < jandegr> :)
13:51 #navit: < KaZeR> some time ago someone came on the channel asking about building maps from non public datas (private roads inside a factory)
13:53 #navit: < alex____> anyway, mapserver should build the maps from osm data, and geofabrik is a good source to get it, they have a nice catalog to be used as a base for maps regions
13:54 #navit: < alex____> i.e. usually u need to download few states, not a boxed region
13:55 #navit: < jandegr> then you have to work like zanavi does
13:56 #navit: < alex____> what do u mean ?
14:02 #navit: < jandegr> zanavi does provide downloading states instead of boced regions
14:03 #navit: < jandegr> however I still prefer the way tryagain proposed a few days ago
14:03 #navit: < alex____> ah, zanavi ... android app, but maybe try to fix "known issue" ? jandegr yes and this is a proper way to provide a maps
14:04 #navit: < jandegr> but zanavi (zoff) builds planet in one go as well
14:04 #navit: < alex____> what the tryagain way ?
14:05 #navit: < jandegr> he posted a link to wiki a wile ago, kazer probably still has the link
14:06 #navit: < alex____> or maybe take a look for zanavi source ... btw, this is a bug in maptool or in map display stuff ?
14:08 #navit: < jandegr> AFAIK it is not a bug
14:09 #navit: < jandegr> if you build a country, then all the rest is ocean, unless you omitted oceans in the build
14:12 #navit: < jandegr> build 2 countries and get 2 slightly different oceans
14:13 #navit: < jandegr> + with maps from geofabrik risk of rivers flooding as well
14:14 #navit: < alex____> hm, might be from some other point of view this is a feature. but actually boxed maps not usable, and yes, in my regions there are a lot of lakes, rivers ...
14:16 #navit: < alex____> and i got the same with one boxed map ...
14:16 #navit: < jandegr> then you got some river or lake flooding
14:18 #navit: < alex____> i don't think there are a lot of navit users in a deserts :)
14:23 #navit: < alex____> but, what to do with that ?
14:24 #navit: < alex____> and, from my point of view this is a bug, because u cannot view regions with rivers and lakes with this flooding effect.
14:54 #navit: < robertp> Hi guys, i have a question: At vehicle.c (or audio.c or service.c) there is a type check of the object defined in navit.xml. When does this type check fail, if the plugin has the same name like the object in navit.xml?
14:54 #navit: < Basilic_> hi robertp
14:54 #navit: < robertp> \o/
15:02 #navit: < alex____> well, using one country is fine, this bug appear using more than one

17:20 #navit: < KaZeR> hey Basilic_
17:21 #navit: < KaZeR> alex____: this is indeed a bug, caused by the way we currently build the maps. This would be in maptool
17:21 #navit: < KaZeR> Tryagain is really familiar with maptool
17:23 #navit: < KaZeR> alex____: here's tryagain's thoughts on the map download service : http://wiki.navit-project.org/index.php/User:Tryagain/Map_replication#Suggested_solutions
18:02 #navit: < alex____> yep
18:03 #navit: < alex____> KaZeR but this is again about tiles, i.e. "boxed" regions.
18:06 #navit: < alex____> my propose is similar, but instead of some tiles i suggest to use common regions i.e. countries, states, administrative areas - from geobaric
18:06 #navit: < alex____> geofabric
18:06 #navit: < alex____> also i didn't see any reason to use https
18:07 #navit: < KaZeR> you will have the same issue with regions. we tested it when we tried to use circle ci to build maps from geofabrik
18:08 #navit: < alex____> all u need is ed25519 sign/verify stuff and shared public key - http/ftp is enough. some code on server is required anyways.
18:09 #navit: < alex____> KaZeR well, this issue with "flooding" should be fixed i guess
18:09 #navit: < KaZeR> alex____: i definitely agree :)
18:10 #navit: < KaZeR> tryagain is less present on irc lately, so maybe we should open a new ticket on trac to focus the effort on this. He knows maptool really well, and he also knows about this issue, this could be an asset
18:14 #navit: < alex____> yes, agreed
18:14 #navit: < alex____> but if you will read my approach it will be very similar - i'm about mapdiff
18:15 #navit: < KaZeR> i am not sure that mapdiff would help with the flooded map issue, as it is a problem in the map generation, not map extraction. I might be mistaken :)
18:19 #navit: < alex____> mapdiff will not help with flooding
18:19 #navit: < alex____> it will help to update map in efficient way i.e. avoid to download a whole region
18:20 #navit: < KaZeR> so i'm lost :) weren't we talking about the flood issue?
18:20 #navit: < alex____> ah ok :)
18:21 #navit: < alex____> flooding issue is just a "new" problem :)
18:22 #navit: < alex____> to run mapserver i have one problem left - mapdiff and a few little tasks
18:23 #navit: < alex____> i'm already tested queues of mapserver, it works well, downloading osm data, checking for changes, run maptool and generates bin file situable to be used on navit.
18:25 #navit: < alex____> and, i'm using regions, not boxed ones, but countries, states, administrative lands from geofabrik - and flooding annoy me.
18:25 #navit: < alex____> that's why we're talking about flooding
18:26 #navit: < alex____> because flooding doesn't looks like a nice user expirience :)
18:26 #navit: < KaZeR> ah, makes sense now
18:26 #navit: < KaZeR> yeah, regions are much better than bounding boxes
18:26 #navit: < alex____> right

18:28 #navit: < alex____> because, just example, in my case i don't need a boxed map, Finland, Estonia, nw region of Russia (East Karelia), Poland and Germany that's all i need
18:29 #navit: < alex____> if i will make a box ........
18:30 #navit: < KaZeR> i definitely get it. Having regions also makes it easier to download, from a menu, from the app
18:31 #navit: < KaZeR> this is all part of why we want to improve map download :)
18:32 #navit: < alex____> yeah, right, u can see catalog of the regions, not boxes, and download or update it
18:35 #navit: < KaZeR> exactly
18:36 #navit: < alex____> and as i understood tryagain's solution is a workaround for flooding bug. also, boxes ... guess nobody will use navit if we will have boxes, especially on android, since zanavi already implement regions not boxes
18:37 #navit: < alex____> right, and navit really needs to fix flooding bug, not to make ugly workaround
18:45 #navit: < KaZeR> boxes are not a workaround for the flooding bug. Also, if we continue to process OSM datas as one map, then serve subsets of that map, then we don't have the flooding bug problem
