Offline vector maps (tile maps for 1-14 zoom levels)

Offline vector maps (tile maps for 1-14 zoom levels)

Absolutely offline maps. No need to have an Internet connection. All data included in the asset making it fast and works offline! Asset includes 8 zoom levels. Higher levels you can download by your own and asset will build them. See instruction file for full information.

This asset allows you to move around the map, approach a selected point, for example, a city that interests you. You can create entities and move them around the map. Also you can see longitude and latitude of entity on the map.

All data is stored as .pbf files (tiles) in local database (.mbtiles file). Local database included in this asset contains 8 levels of zoom. Each level of zoom contains (2^zoom) * (2^zoom) number of tiles (pbf files):
1 level - 4 tiles (pbf files);
2 level - 16 tiles (pbf files);
3 level - 64 tiles (pbf files);
4 level - 256 tiles (pbf files);
5 level - 1024 tiles (pbf files);
6 level - 4096 tiles (pbf files);
7 level - 16384 tiles (pbf files);
8 level - 65536 tiles (pbf files);
Total - 87380 tiles (pbf files) are stored in database.
You are able to add your own "mbtiles" files with higher zoom levels (see instruction file for full information) and this asset will build them. This asset can create buildings and streets. Works perfectly for 1-14 zoom levels.

There are three types of geometry that describe all geo data: linestring, polygon and point. The mechanism of constructing geographical data performs the following functions:
• function that gets pbf files from local database (sql);
• function of converting bytes to geographical data;
• function of creating meshes for country borders, region borders, rivers and different types of roads;
• function of triangulation of lists of points and creating meshes for polygons;
• function of creating points (text meshes) for text labels;
Also asset contains mechanisms that control map tiles construction, control movement and zoom, hide and show map tiles, control the creation of entities and calculation of their geo coordinates.

You can customize all map view:
- change color of water, ground, country borders, region borders;
- change size of names on the map;
- switch off or switch on the display of country names, city and state names, ocean, sea and lake names, country borders, region borders;
- change map style (dark and light);
- change language of names on the map (official, russian and english);

Works perfectly on Windows and Linux systems.
If you have Mac system, you need to store pbf files locally (not in Sql database). So, you can extract them from Sql database by your own or write to me and I'll send them to you. After that all will be working great for Mac too.

If you have any questions you can ask me any time. Have a good day!
