These are simple xml files that define the location of the tiled map, and some other parameters which tell MOBAC how to process the map. MOBAC looks in this directory for custom map sources. Figure 1: MOBAC program folder with the mapsources sub-folder One of the folders in the MOBAC program folder is the ‘mapsources’ directory (see image below). Unfortunately, this is not very straightforward to do. To convert your tiled map, you need to make sure MOBAC can find it. The output is a set of folders, which contain the map tiles, and a doc.kml file.ģ) Convert the tiled map in the required formatĬonverting can be done in MOBAC, which creates atlases for several applications. Note that rendering the map may take some time, depending on the size of the map and the zoom levels to be created. Next you need to select the spatial reference system of your input layer. This is the projection expected by Mobile Atlas Creator, the program we are going to use later on. But make sure in the first step to select “Google Maps compatible (Spherical Mercator)”. The steps are kind of obvious just follow the steps of the MapTiler wizard. Next step is to create a tiled map using Maptiler. Most GIS programs will have the option to export your raster data in at least one of these formats. Maptiler, which we are going to use in the next step, supports many formats, including TIFF/GeoTIFF, MrSID, ECW, JPEG2000, Erdas HFA, NOAA BSB, and JPEG.
You’ll need your favorite GIS application (e.g., GRASS or QGIS), Maptiler, and Mobile Atlas Creator ( MOBAC).Įdit: If your app can read MBtiles, there is an easier way, especially if you want to create a map made up of different data layers: read more…ġ) Create georeferenced image of your mapįirst step is to create a georeferenced image of the map you want to use.
MAPTILER CHANGING ZOOM LEVEL ANDROID
But what if you want to use your own maps? If you are using an Android smartphone and one of the map viewers available on android market, this is fairly easy. Outdoor sport or field work, a GPS has become indispensable.
