Any possible way to see past versions of OGF? over 1 year ago

Yes, but it is most likely not an easy way. You can take the complete Dataset, strip it of current data (with special tools), set up a something to render your map.

Nominatim over 2 years ago

I'm the one who's providing the Nominatim-Server so the Admins aren't the ones to bother with this problem :P

The update process is supposed to run in the Background, that's why i didn't see that problem so far. According to the logs this problem is caused by an error with a specific cache. I'll try to solve the problem tomorrow, just got home and need some sleep.

When i'm done with problem solving i'll change the HTML to include the default OGF-Tiles.

Kind Regards

Verisimilitude on a global level: on the ever-growing number of small States over 2 years ago

We'll cross that bridge when we come to it :)

As you already pointed out there are quite a few reasons why stuff gets refined/reuploaded on OSM, after all we don't have to deal with constant construction sites, new satelite imagery, detours, shops closing and opening, our world is much more stationary in these regards... I personally think that this way there is a whole load more attic data in OSM than OGF, Relations also get changed a whole freaking lot, i also found some nodes with version numbers high as 81 in OSM, unfortunately i can't run the same query on the OGF-Overpass because these features are only implemented in the development-overpass (which runs way smoother than i expected at first).

I'd love to run an attic comparison, maybe with something that is comparable pbf-file-sized if i knew how exactly...

Something Different: The History of a Square in Ostrina, Antharia over 2 years ago

I was wondering if there is an OSM to Sketchup, that way one wouldn't have to do everything in sketchup again, as in importing OSM/OGF-Data into sketchup so that the buildings and their features (roofs, wall colours, levels, height...) are generated automatically based on the 3D-Building-Data, meaning less work when you want to have it in 3D (only refining, adding windows and stuff).

Something Different: The History of a Square in Ostrina, Antharia over 2 years ago

huh, i wonder if there is an import function for OSM-structured data into sketchup, that way something like the f4maps would be possible...

Anyway, your work looks really interesting, although i don't like your roof-mapping from a data-point of view. It looks awesome, but there's 3D-Buildings for this purpose, which enables consistent rendering for many data users, but unfortunately we have no renderer for that so i understand your decision to go for something that is rendered.

While researching for this comment i also found this 2.5D-Mapnik renderer, maybe we could implement something similar which just generates roof outlines.

Crowded Server? over 2 years ago

If your country should be really that crowded you can always start indoor mapping, OSM is just getting started with this and the results are looking really nice, see here for an example, look at the buttons on the right side of the page to select the different levels.

Also there is no lag in OGF, the only thing that could happen are conflicting edits if you are working in a blue country and someone else is faster with uploading than you.

Verisimilitude on a global level: on the ever-growing number of small States over 2 years ago

I doubt that server space is much of a problem, so far we are at node 94.703.613 while OSM is at 5.170.868.239.

I personally like the OSM Data-structure as it allows you to render and search the (Attic Data).

What every user can do to save a bit of space is to "recycle" nodes when deleting stuff, that way there isn't a new node created but just another version appended to an already existing one.

Also the PBF-Data-Structure is optimized to use as little Hard Drive Space as possible, the whole OGF-World, including all attic-data is about 350MB, i think that expands to about 3 GB but i am not really sure because i never deal with raw data.

Kind regards

Labels over 2 years ago

Kinda related: The outer ways still contain some attributes, this isn't necessary since they are no closed ways.

Verisimilitude on a global level: on the ever-growing number of small States over 2 years ago

Oh, i totally forgot to mention my idea for neighborhoodial, borderbased collaboration:

How about every neighbor can edit in another users country 5km from the borders to connect roads, railways, ferries and other line-based features. In conjuction with that i would want to allow proposing such features up to 20 km land-inward. Obviously the "land-owner" still has full rights in the corresponding country and is free to delete such features, but all in all this would lead to more organic, ad-hoc collaboration.

Verisimilitude on a global level: on the ever-growing number of small States over 2 years ago

My recap of previous entrys sums up to the following, correct me if i'm wrong:

We need a more intuitive platform to share ideas and more collaboration tools

  1. I could set up a forum on my server, maybe even with oAuth so there are no further credentials needed.
  2. I will set up an uMap server for easier sketching, it can be used in conjuction with overpass queries to "render" stuff that is not visible on the default map (e.g. proposed features), see here for more info.
  3. For comments on the bare map we could use the feature that was integrated into OSM for error correction -> http://opengeofiction.net/note/new
  4. Is a Mailing-list a possible solution?

(New) contributors need more guidance

  1. I think some pool of volutary experts on a specific topic would help here, maybe in conjuction with a forum
  2. Maybe embedding an FAQ-Link in the new diary entry page e.g. "If you have questions in regards of mapping, look [here](opengeofiction.net/faq)

The admin team needs more people and a better way of communication

  1. I would happily help out wherever i can
  2. As mentioned before, would setting up a forum help here?

Filling a large country is difficult

  1. I can totally agree to that
  2. As bhj867 mentioned having teams working together on countries would help here, also the "expert-pool" proposed before could help the teams

On other things

Regarding the cultural and linguistic "mess" that OGF can be sometimes: We could make an overlay map regarding Linguistic areas and tag all stuff in it with name:en=*, that way someone willing to translate in the countries language could easily run an overpass Query and translate the features found. In the light of recent events i wouldn't want some third party service for communication (disqus, discord and so on), only self-hosting is an option for me. Speaking of that i could offer an mumble-server for voicechats.

Kind regards

Working with Maperitive over 2 years ago

If this is still about your meter vs. regular-tram-diary-entry from last time: You need to tag the corresponding trams with gauge=* where *= the gauge in milimeters. After that you can set up an ruleset in maperative and import the data you want to render.

OSRM Direction finder over 2 years ago

Stuff should work again now, the server restarted for unknown reasons and i got no mail from my hoster so far why exactly.

Nominatim was down too, Stuff should work again now.

Weekly Word; Hot Challenge over 2 years ago

Hey,

my entry for this week is the Feuerwehrtrainingszentrum Allerswarte, it is a training and education facility for firefighters from the whole country. It was recently completely rebuild due to the fact that the old facilities where not adequate for the number of people and all the tasks firefighters have to be trained for.

Hope that counts as hot enough to participate. If you look at the raw data you'll notice that i mapped it fully OSM-compliant and it could be used to generate a 3D map like the F4Maps for OSM. Also i added building-reference-numbers to all buildings and building-parts.

Kind Regards

Tagging dual tram networks over 2 years ago

Well, you could make a coloured overpass-query, but thats not really rendering. Another option would be a full blown geoinformation suite like grassgis or qgis. A smaller solution would be Maperitive.

Anyway, in all three cases you have to put a little bit of work in it, the easiest would be an overpass query IMHO.

Kind Regards

Have some relation problems with St. Richards over 2 years ago

Easy fix, just tested: Load stuff into JOSM, select inner and outer and press Ctrl + Shift + B to update the multipolygon, it will move the tags from the outer to the multipolygon itself.

Kind regards

Ocean Mills over 2 years ago

And that airport is quite unnecessary, it's only about 20km to the next big one...

Ocean Mills over 2 years ago

I'd go for more names regarding surrounding natural features, also you have quite a lot of streets with sharp angles (α< 90°), it makes placing useful houses near them quite difficult because one is wasting a lot of space.

What's wrong with my JOSM? over 2 years ago

The mentioning Discord is our own godwins law :)

Regarding JOSM: Img if your JOSM looks like this it is completely normal, you just have to embed the image layer if you want

OSRM Routing service Update over 2 years ago

Thanks for your feedback :)

It may depend on multiple factors, for example left turns and traffic signals are penalized a little bit, maybe you didn't set any maxspeeds, see here for information on which highway-type is assumed with which default speed or maybe your roads don't share nodes. Thilo was so kind and used his javascript-skills to create this for further routing-graph-information on the exact speeds and times used.

Maybe you could provide an example route and i can try to find an explaination.

Kind regards

What could be the best and most worked on location in OGF? over 2 years ago

That all is dependent on how you define best and most worked... Most people just tag "for the renderer" and not really care about the underlying data, so even if something looks great on the map it might not be good data-wise lile something that is not as well mapped.

As someone who wants to create more i really care about all the Data and even map Stuff like opening hours, highway lanes, a bunch of reference numbers and some other things. It might not be rendered but I think it's important anyway.

Kind regards

Martin
