pbf | A low-level , lightweight protocol buffers implementation | Serialization library

Hi I am having trouble with some file handling in Xamarin forms. Each time I run my code I keep getting the systemIO FileNotfound exception. The code I am using is below. The stuff about routerDB is part of a pathfinding NuGet package I am using called Itinero. Before my code can even reach the create routerDb.LoadOsmData line it keeps getting stuck at line 4 and returning the error: System.IO.FileNotFoundException: 'Could not find file "/Date\wales-latest.osm.pbf"'

Here is the the absolute path of that file "wales-latest.osm.pbf" in Xamarin forms.

C:\USW Pathfinder\USW Pathfinder\USW Pathfinder\bin\Debug\Date

I was so frustrated this did not work that I created another program but this time a windows forms one and I entered the same code as below and it worked first time flawlessly and created me the file wales.router.db as I expected.

Here is the absolute path of that file "wales-latest.osm.pbf" in Windows forms.

C:\Users\MYNAME\Desktop\Pathfinder\Pathfinder\bin\Debug\Date

I have also tried simpler file handling code in Xamarin forms to see if I can reach any file as shown in the second code block and I am always met with file not found.

Please can anyone suggest why this would be?

I have an .osm.pbf file which I want to use to generate vector tiles with (.mbtiles).

Im currently on a windows machine utilising docker, I have tried to use the tool tilemaker (https://github.com/systemed/tilemaker) though I cannot get it to work on my files and get issues like so

" terminate called after throwing an instance of 'std::runtime_error' what(): Exception during zlib decompression: (-5) "

I was just wondering if anyone else was able to generate these tiles from said file type, if so could you provide a low level detailed guide on how you did so, as I am new to vector tiles and am getting confused within some circumstances.

For anyone interested I use this code to run the docker:

My goal is to validate an address in Austria. Without a house number, just street, postcode and city(village etc).
I have downloaded and imported austria-latest.osm.pbf from geofabrik.
My approach was to get all postcodes, then all locations for certain postcode and at the end all roads for location. I'm using st_intersects and geometries to connect.
But i'm stuck with "Gemeinden" and can't go deeper. As example "Gemeinde Längenfeld". Google Maps Wikipedia, german You don't find "Längenfeld" as location on the address, just "Oberlängenfeld, Unterlängenfeld" and so on, but they only exists as "places" and places are just points, so i cant connect roads to them.

Do you have any hints for me? Thanks you !
P.S. we have our instance of nominatim and use it as fallback

I am using Azure Maps, and want to display vector tiles that I have generated with tippecanoe.

I was initially getting an error in Azure Maps in the frontend javascript, which was basically complaining the generated pbf were not acceptable, because it was compressed. I fixed that.

Now, the frontend javascript does not throw any error, except when it cannot find a z/x/y pbf file.

When it does not throw any errors in the javascript console.log, it does not display any vector from the vector tile pbf.

What I think I am not getting right is the sourceLayer that goes into the javascript.

I have a pbf file, made with

This may be in the series of dumb questions, but when I look at https://deck.gl/docs/api-reference/geo-layers/mvt-layer, I do not understand how to make a MVTLayer that fetches self-hosted tiles without React pieces. Can someone help? This would feel to be even large interest now that buildless is also becoming a thing in web programming.

What I would like to achieve is a simple HTML (e.g. index.html) file that uses a script tag like and the example from the aforementioned Deck.gl that looks like (I changed the URL)

Our platform currently uses pbf tiles(on s3) to render vector layers on Mapbox on the frontend. The pbf tiles have separate layers within them and we use Mapbox layers' source-layer property to style them as separate layers. We are now moving to PostGIS and we want to avoid s3 and directly render the vector tiles as mvt on the frontend.

I am trying to get separate layers from the mvt but the only layer I see is a 'default' layer. I identified this using this vizualizer tool. I am currently getting the mvt using this query -

In our experience ExoPlayer does not use lower bitrate even there is latency in downloading big chunks and this causes freezing and buffering. However the bandwith is 6 Mbit, because of VBR sometimes the size of one 2 second chunk differs from 1.5 MegeByte to 15 MegaByte. In our experience when there is increase in bitrate the player still tries to download next chunk using same bitrate instead of lowering bitrate. What is causing this problem. Is there a way or configuration to fix this?

We are using default values of buffer sizes and track selection durations.

I want to extract some information from a .osm.pbf file. I looked through OpenStreetMapX.jl package but didn't find a function to read this data. I am wondering if anyone know a method to read this data. Alternatively is there a way to convert .osm.pbf to .osm file so that I found just use the get_map_data() method offered by OpenStreetMapX package
