Hello, there will be an OpenStreetMap Hackweekend in Berlin at September 15./16. The organizing is taking place at the OSM-Wiki [1], where you can also put your name in a list if you want to join. It helps to organize the event if you do. If you like you can also follow the Meetup event [2] The day before, Friday 14th, there will be the monthly Stammtisch [3].

[OSM-dev] OpenStreetMap Hack Weekend Berlin 2018
Hello, I'm happy to annouce that there will be hack weekends hosted in Berlin in 2018. The first one is scheduled in April, a second one probably in August. We also found a new location, some OSM hacker might already know. It will hosted at the mindbox from Deutsche Bahn. The OSM Wiki [1] was updated with latest infos. A formal announcement will follow approximately 4-6 week in advance. Please also check if the hack weekend held in Karlsruhe [2] suits you better. It will take place in February. Best wishes, Lars [1] https://wiki.openstreetmap.org/wiki/Berlin_Hack_Weekend_April_2018 [2] https://wiki.openstreetmap.org/wiki/Karlsruhe_Hack_Weekend_February_2018 ___ dev mailing list dev@openstreetmap.org https://lists.openstreetmap.org/listinfo/dev
Re: [OSM-dev] cross-fade map sample code (ol3 or leaflet)

What I actually want is > dissolving layers transparently like in http://sautter.com/map I see, I wasn't sure about the transparency. I couldn't find an exact example. But have a look at [1]. My idea would be to modify one layer slider so that it is effecting the transparency of two layers. > > Sven > > P.S.: Looks like the correct word for "überblenden" is dissolve in this case > not fade. > Thanks, thats helpful. I ended up searching for the word "swipe" which isn't right either.

There are examples for OL3 [1] and for Leaflet [2] and [3]. Hope this helps.

Re: [OSM-dev] osm2pgsql bbox filter when applying diffs?

I think it only filters nodes, I haven't checked for a while but previously I had ways with no nodes in the database outside the area I was filtering... What would be the best way to keep an individual extent updated? Fetching the planet, extracting the extent of the area of interest and create my own diffs? I could also apply the planet wide diffs and remove everything outside of the extent afterwards. But I don't like this idea. Is there a way to process the diff files in a way that the diff only contains changes in my area of interest? Thanks for any hints.

Re: [OSM-dev] Mirroring OpenStreetMap
Ian Monroe schrieb: I'm going to talk tomorrow with the director of WiderNet, which has an eGranary Digital Library project that mirrors websites on to hard disks and sends them to schools and hospitals in the developing world (mainly Africa) which have slow or no Internet. So currently the eGranary is 2 terabytes containing Wikipedia, opencourseware, books etc. My thought was that OpenStreetMap would be a great addition to it. And OSM really has more to offer Africa then anywhere else due to lack of commercial maps on the web. I volunteered to perhaps implement this because I have the technical skills in general to be able to set it up, but not because I know much about OSM technology in particular. :) I'm finding the resources on rendering a bit hard to get into. Right now the important question is the feasibility. How big is a fully rendered OpenStreetMap? Or would it make more sense to render on-the-fly? For offline usage of OSM I created an live cd environment. It uses extracts from the planet file and covers only some parts for Europe for now. It uses PostgreSQL, MapServer to query and render the data and MapFish as client to interact with the map. Depending on the bounding box I could create a cd image for africa. You don't need the whole planet on a disc, don't you? That wouldn't be possible. You can grab a copy from http://www.lingner.eu/discosm/download/ Its a prototype to prove that you can have a live OSM rendering on a disc. First thing you (and others) might struggle with: It is build only for x86_64 architecture. As a minimum of RAM you'll need 1 GB. With more than that, you can load everything into RAM and then its pretty fast. If it fits your needs or at least some of them, let me know. In the last weeks I had no time for new features but the OSM data is from around 20th January 2010 Putting the tiles on CD/DVD could be more complicated as you will need a lot of those discs (sorry no current number available) depending on the extent you need to cover. I'm sure other users have some more ideas so you can compare different solutions. Lars ___ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev
