is there any posibility to show only Germany Country Borders and inner Data with Mapbox ?
I dont want the rest of the world displayed.
Thankx,
Markus
Yes. Use the Germany GeoJSON from http://code.highcharts.com/mapdata/. Upload it as a dataset, export it to tilesets, and then to a map as a layer. Delete all other layers.

I am using Django, leaflet and openstreetmap.org to display the map in osm and topo formats. How to display just the map of a country. For example just display the map of Algeria? Thank you so much.
This trick can achieve what you need.
You can add a geojson file with the geometry of the country you want then customize the polygon to show just the country.
In the next link you will see a code example.

I made my own google map with historical information (of houses and people in the 50-s in Princenhage, The Netherlands):

Now I would like to add an aerial photograph of 1950 as an extra layer on this map so that my map looks as 'google earth in 1950'.
Is this possible and how to do this?
It is possible but you need to make a baseMap of your aerial photo. If you managed that you can use this example to add the basemap to your viewer:

I have a complete set of waypoints (beginning, end, every intersection) and I'd like to display this on a map. I don't want to use a routing service and it should be offline.
How can I draw polylines on a map so that they follow the curves of the road?
I'm using leaflet.
Could the data be extracted from a relational database(PostgreSQL) and then convert it into GeoJSON and display on the map by leaflet?
I can't use any paid services either.
Leaflet has a polyline object. MapBox has a nice example how to use it.
I think scai has given you a good example to practice.By the way you can also store the data in JSON format in PostgreSQL.Refer this documentation for more details.JSON Types
I'm using Leaflet and MapBox. I need to develop an api which will show certain city points with labels, and accordingly draw routes between them. I have BlueMarble tiles till certain zoom, and then MapBox Streets. What is the best way to realize that idea? Are circles and paths the best option? Thank you.
I am not sure that you need to create an API for what you want to do.
http://leaflet.cloudmade.com/examples/geojson.html
In the Leaflet tutorials it shows you how to create LineStrings and Points from GeoJson data. So with latitude and longitude coordinates for the Cities you can create Points and use LineStrings to create the routes and add a them as a GeoJson Layer to the map.
I want to display map like geo chart api in google Geo chart
and highlight particular country. How to Achieve This in offline..
Any Suggestions please..
Thanks in advance.
I would look at something like the data from Natural Earth and put it in a either a sqlite3 or spatialite database. Then create a georeferenced view that will translate points on the screen to lat/lon coordinates and vice versa. Finally you can look up the lat/lon coordinates in the database to draw the country outlines and highlight the countries while you draw the screen.
If you are thinking of zooming the map, you probably want to look at getting multiple resolutions for the data as drawing a high resolution map can be slow.
