Hello,

i would like to present my apps, which are OpenStreetMap based city maps that work completely offline.
Currently there are 3 apps available for free, which are the maps for Berlin, Düsseldorf and Graz:

Berlin Offline City Map, Düsseldorf Offline City Map, Graz Offline City Map

Main features are:
  • Browsing the map
  • Finding streets by name (with partial matching)
  • Finding points of interest by category and name

When you start the app, the first thing the app does is to extract the map data so that you can use the program without an internet connection from now on. It does not download any images or something, but installs a database which will then be used to produce the map images live and on demand. This database is filled with data from the OpenStreetMap project, which is why the maps are quite complete and up to date.

After that, the app presents the map of the city. You can move around here, view it on many different zoom levels, just how you wold expect it from any map software.

The following screenshots give an impression of the screens available within Berlin Offline City Map:




The categories of points of interest currently available are the following:
attractions, museums, theatres, cinemas, places of worship, hotels, hostels, guest houses, restaurants, fast-food, cafes, pubs, bars, beer gardens, nightclubs, shops for clothes, shoes, jewelry and also railway / bus / tram stops.

Once you hit the 'search' button, or via 'menu' -> 'search', you get a the list of categories to choose what you want to look for:


After selecting one of the items, you will get a search form to enter your query. The text-field will suggest completion of your input depending on the data available. Alternatively, you can also browse the whole dataset of each category page-wise. When you select an item you found, the app will zoom in to the location and place a red marker at the position of the item.

Here are also some screenshot for Düsseldorf Offline City Map:



and also for Graz Offline City Map:

Thanks! Fortunately the map display is handled by an android library from Mapsforge, which eliminates a lot of development issues. Even though, it took some time to develop an overall nice user interface and a satisfactory user experience concerning street and point of interest search.
