[OSM-dev] Playback of Camera Movement in OSM2World Question
Hi, My name is Wilson Cao, I currently attend the University of British Columbia, and I am interested in the 3D modeling of the OSM2World. I am planning to apply as a GSOC student, and I have a couple of questions regarding the issue of playback of camera movements in the OSM2World. (1). Just to confirm,is the purpose of the suggested project is to capture movements of objects, cars and planes, with a camera and render the object into the OSM2World. If so, will it be objects updated in real time? Also, where can I find the XML files for the OSM2World data? Thanks!

It's certainly possible; I've got something very like that sat on a VM on a desktop PC about five feet away :) Depending on how much technical expertise I require for this, I plan to develop these tile sets in response to demand from the UK community in response the the change of colours recently. The British tile set will have the old colours before the changeover to the red-yellow scheme, and it initially cover Great Britain and the Republic of Ireland only. The Greek tile set will have green for motorways, two shades of blue for national roads, red for provincial roads and yellow for other connecting roads to villages, and it will initially cover Greece. This stylesheet reflects the road signs on motorways and national roads, with the rest being based on the old stylesheet. Other than the change of colour, I plan to make the custom tile set stylesheet a dependency of the main stylesheet, to minimise the need to update them often. I desire that the tiles update about five minutes after an edit, like the main map, so it does not turn out to be a half-baked alternative. First, start with https://switch2osm.org/serving-tiles/manually-building-a-tile-server-14-04/ . That'll talk you through the basics of setting up a tile server. I'd start with something small (an English county, perhaps) so that when you need to reload because something has gone wrong, you can do so quickly. Initially I'd stick as close as possible to the instructions as written, so that if something goes wrong you can be reasonably sure that it was something that you misread, not something different you tried to do. I'd also initially use a virtual machine of some sort, perhaps running on a desktop or laptop you have - that way it's possible to revert to a previously working setup easily if something goes wrong. For small areas a couple of Gb of memory and around 20Gb disk should be enough - though when you start wanting to render UK and Greece you'll need more (at a guess, 8Gb memory might be enough - but someone else would need to confirm). I ran through the instructions a couple of months to go "soup to nuts" and they worked; the only issue I'm aware of since then is that the "Installing osm2pgsql" bit needs to be changed slightly due to some recent commits there. Details are on https://github.com/openstreetmap/osm2pgsql , but if you have problems with that just get a couple-of-months-old version of osm2pgsql from git and run with that. After that you should have a tile server and should be able to browse to your equivalent of http://b.tile.openstreetmap.org/0/0/0.png . Do be aware that creating low zoom tiles on a small server can take a while (minutes) - so don't expect pretty pictures immediately. The switch2osm instructions describing looking at logs to watch requests for tiles to be rendered. You'll want a basic map viewer - I'd use Leaflet for that. See https://switch2osm.org/using-tiles/getting-started-with-leaflet/ (which actually contains rather more details than you need - just look at the links to the Leaflet site) and there are lots of examples, tutorials etc. on http://leafletjs.com/ . As an alternative, if you want to cheat you can have your tiles behind osm.org - see http://wiki.openstreetmap.org/wiki/User:SomeoneElse/Your_tiles_from_osm.org for that. By this stage you've got a database and some "OSM Bright" tiles. You'll want to add a new tile layer initially consisting of OSM's "standard layer" ones. The "standard style" is over at https://github.com/gravitystorm/openstreetmap-carto , and there's a link to the installation document from the readme there. In order to add more tile layers to your "renderd.conf" file (which you will have created during the "manually-building-a-tile-server-14-04" process), have a look at these questions: https://help.openstreetmap.org/questions/45011/serving-multiple-layers-on-single-tile-server http://gis.stackexchange.com/questions/79077/serving-multiple-styles-from-tile-server OSM's standard style installation instructions "just worked" for me when I last tried them, which was last year just before OSM moved to "orange roads". Next, you'll want to add your new tile layer to your Leaflet site - that's pretty straightforward and many or most of the Leaflet examples I mentioned above use multiple tile layers. After that, it's on to changing road colours. At the top of https://github.com/gravitystorm/openstreetmap-carto/blob/master/roads.mss there are a bunch of colours. Initially, I'd try changing those to different values in your copy of the file, rerunning the "carto" command line (which you'll have previously run with the styles you've setup alr

Re: [OSM-dev] Playback of Camera Movement in OSM2World Question
Hi Peter, I am intrigued. I plan to install OSM2World and follow it. I work on the problematics from another side. I work on using real flights to capture data for 3D mapping and make it readily available for all mappers. It is possible to publish 3D aerial images both into a Wikipedia article and a respective Wikipedia category. There's an OSM tag also for a category. Here are the aerial images of Collège Madame de Staël in Geneva which I made with the DJI Phatom 3 this week: https://fr.m.wikipedia.org/wiki/Coll%C3%A8ge_Madame_de_Sta%C3%ABl# https://commons.m.wikimedia.org/wiki/User:Alexey_M./gallery An advantage of Wikipedia is that it keeps the original images resolution, so building:levels are well visible. Google Maps automatically reduces resolution. DJI Phantom 3 has got the range of 2.2 km, and the new Phantom 4 has got the range of 4.5 km (3 miles). But the range is also limited by the constant visual contact required by law. So actually it is about 1 km (and the maximum allowed altitude 150 meters in this case). Still it is enough to cover quite a large area. Phantom 4 has got increased reliability due to doubled systems, but in any case it's recommended to perform hundreds of training flights before even considering a takeoff in a city. DJI Phantom writes coordinates and altitude into JPGs Exif automatically, so an automation is possible.
