Android Question OpenStreetMap using .PBF?

[adrianstanescu85]

Hello,

I'd like to ask if there's a solution to use the maps from OpenStreetMap project using directly the .PBF files (offline) that are freely available for download.

For instance, http://download.geofabrik.de/europe.html has every country in Europe being updated daily in that vector format so using such a file would give an immense advantage over the OsmDroid tiles approach, which may be downloaded or generated but take up a huge amount of space and time.

I would also like to ask if using the alternative SHP or OSM formats is possible in a similar way, if PBF is not (which I would expect).

Any info over this please?

Thank you!
Adrian

Do you want MapsForgeTileSource for OSMDroid version 3.0.8 or the newer 4.1?

For version 3.0.8 you want to download: http://b4a.martinpearman.co.uk/osmdroid/MapsForgeTileSource 20140308.zip

And for version 4.1 download: http://b4a.martinpearman.co.uk/osmdroid/OSMDroid_4_1_MapsForgeTileSource-20140520.zip

You can browse that folder on my server to see exactly what is available: http://b4a.martinpearman.co.uk/osmdroid/

 

[Carlo2015]

I downloaded both.

I also downloaded the example 4.1

I really appreciate it sir. Thanks!

HI, GREETINGS, MARTIN
I CHECK YOUR MAPSFORGE EXAMPLE :
WHAT IS THE IDEA TO SavedMapStateFileName (map_state.dat)
IF NECESSARY TO 100 PERCENT, I SAY YOU BECAUSE NOT PUT THIS AND THE EXAMPLE STILL WORKS WELL

THANKS

Hi.

It's just a way to save and restore the map state when the device orientation changes.
It's not required - it's just an optional extra.

Martin.

Greetings martin
i wanted to know if you could get an idea of where is this part (of white on my apk). I've reviewed several parts... where is the part of the code to change the area color white or color area white...

...
the idea is display little transitions change when zooming in-out .
As i could do to see my apk zoom in-out transitions like a google maps
tks

Looks like you've already experimented with changing the map background color in the render theme xml file?
The very first line of the render theme xml looks like this:

<rendertheme xsi:schemaLocation="http://mapsforge.org/renderTheme ../renderTheme.xsd" version="1" map-background="#f8f8f8">

Can you change that map-background value to 'sea blue'?

 

[PABLO2013]

GREETINGS MARTIN
I WANTED TO KNOW
WHY THE LINES AND Markers remain static IN A PATHOVERLAY while the rest RESPONDS TO MAP ZOOM LEVEL ... THIS IS NORMAL AS OR could BE correct ... CURRENTLY I USE THE LIBRARY OSMdroid 3_0_8(VER 3.6)

THANKS

@PABLO2013

I'm not sure what the problem is.
Are the markers and path behaving properly but the tile data is 'drifting' - ie the tiles are not being drawn with enough accuracy.
Or is it as you think - the marker and path are not being drawn with enough accuracy so appear to drift?

Can you display the same markers and path using a different tile source and see if the problem lies with the markers and path or with the tile imagery?

MapsForgeTileSource updated to version 1.10
Completely incomapatible with code written using the previous version but much more configurable:

OSMDroid_3_0_8_MapsForgeTileSource
Comment: MapsForgeTileSource enables you to render a MapsForge map database file as a TileSource on an OSMDroid MapView.
Version: 1.10

• MapDatabase
  Methods:
  • IsInitialized As Boolean
  Properties:
  • MapFileInfo As MapFileInfo [read only]
• MapFileInfo
  Methods:
  • IsInitialized As Boolean
  Properties:
  • BoundingBox As BoundingBoxE6Wrapper [read only]
    Get the bounding box of the area covered by the map database file.
  • Comment As String [read only]
    Get the comment field of the map database.
    The comment field can be set when the map database is created.
    It may not have been set, in which case this method will return an empty String "".
  • CreatedBy As String [read only]
    Get the created by field of the map database.
    The created by field can be set when the map database is created.
    It may not have been set, in which case this method will return an empty String "".

    Get the size of the map database, measured in bytes.
  • FileVersion As Int [read only]
    Get the file version of the map database.
  • LanguagePreference As String [read only]
    Get the preferred language for names as defined in ISO 3166-1.
    The preferred language for names can be set when the map database is created.
    It may not have been set, in which case this method will return an empty String "".
  • MapDate As Long [read only]
    Get the date of the map database in milliseconds since January 1, 1970.
  • PoiTags() As Tag [read only]
    Get the POI Tags from the map database.
  • StartPosition As GeoPointWrapper [read only]
    Get the map database start position.

  • StartZoomLevel As Int [read only]
    Get the map start zoom level
    The start zoom can be set when the map database is created.

Hi Martin,
Do you have a demonstration project with version 4.01 of OSMdroid?
Thanks

 

[warwound]

Do you have a demonstration project with version 4.01 of OSMdroid?

To be honest i'm not sure!
If you look at the directory listing here: http://b4a.martinpearman.co.uk/osmdroid/
You'll see some v4.1 examples but i'm not sure if they include a MapsForge example.
The MapsForge example in the listing is, i think, for the previous version 3.08.

If you try to get MapsForge working and have problems then start a new thread and upload your non-working code and i'll take a look.

cheers Martin,
wanted to know is possible at runtime choose different render files ..... i see every time zooms it make a new reading to the render file.... if i'm wrong
I do not know .. . there are new features for this library , tks

......tileRendererLayer.setXmlRenderTheme(new ExternalRenderTheme(File))

 

[PABLO2013]

tks
i solve it , but wanted to know if this works from a button or a menu and if this library has available.


Dim InputStream1 As InputStream
InputStream1 = File.OpenInput( File.DirAssets, "osmarender.xml")
MapsForgeTileSource1.GetMapsForgeTileSourceOptions.SetRenderTheme(InputStream1)

tks

I've attached the OSMDroid MapsForge library for OSMDroid version 4.1.

Your code should work regardless of how it is called.
