Hello! 

Big thanks to the developers of the project!

I have several questions:

1. Can TileSource work without an internet connection? To download my map to a local drive?

2. Can I extend TileSource what any other maps? Such as Ovi or Yahoo?

WinFormSamples very much, but unfortunately, almost everything works only with connection to the Internet.

I would be grateful for any help and support! Thank you!

  1. Yes it can. You may need to compile BruTile yourself to make it work, though.

    You can either use FileTileProvider, a provider that takes the tiles from a directory or the MbTilesProvider, a provider that takes the tiles from an SQLite database that adheres to the MBTiles specification. See the current latest code on brutile.codeplex.com.
  2. Sure you can, it is certainly appreciated. Please post patchfiles/source code to brutile.codeplex.com

One question: You say "tiles from a directory"... I don't have tiles GoogleMaps, OpenStreet and Bing :( 

Where can I get them? Sorry for the stupid questions.

You have several possibilities

  • You need to setup your TileLayer with a FileCache and (in an online session) browse your whole area of interest in every desired zoomlevel.
  • Use TileMill to genereate your tiles
  • Download mbtiles from MapBox
  • Create your tiles from some geotiff using MapTiler

Good afternoon, everybody. Someone's got to solve this problem? I want to use OSM maps offline?
It is even possible to simplify the problem by using local maps .osm or .PBF. Please help. I can not solve this problem for 2 months...

Yes absolutely,

Just follow the instruction there to generate your tiles, this solution does not provide a control to render your tiles, your gonna have to find the control that fits your needs.

This solution is for linux, but I have tested it on Windows, C#, VS2010 and it works.

I had such a problem. I think this is due to the fact that the field is 32 bits, respectively, I reach the upper limit of the index field. The database I can not find the table to change the type of the field to an unsigned. Give advice please

I don't see where osm_node_pkey is. Can you tell me where it is?

When I look at all the planet_osm_* tables created, I see
"
CREATE TABLE planet_osm_point
(
osm_id bigint,
"

If the (id) in the detail message is "osm_id", the limit should be fine:

Maybe your .bz2 file is the problem. Have you tried with the massachusset file given in the example above?
