Gdal layer

GDAL Map layer is included in AdvancedMap project as GdalMapLayer.java. Usage as baselayer:

  gdalLayer = new GdalMapLayer(proj, 0, 18, 9991, Environment.getExternalStorageDirectory().getPath()+"/NE2_HR_LC_SR_W.tif", mapView, true);
  mapView.getLayers().setBaseLayer(gdalLayer);

Usage notes:

• Raster data looks nice on narrow zoom range, downscaling is slow for big datasets and upscaling gives only huge pixels. You may need to adjust visible zoom range by modifying isSuitableZoom() method of the layer, this limits dataset to certain zoom levels close to raster native zoom.
• The layer caches data as map tiles, so next loading is much faster than initial data loading
• The layer supports on the fly reprojection (using GDAL VRT feature), but this is generally at least 2x slower than reading data from same projection as map layer
• Not all GDAL drivers are compiled in, the ones which require additional dependencies (e.g. online data like WMS, or online databases) are therefore not available. If you really need some of these, then we could take a look if this is fixable.
• We have tried out only small list of test files (GeoTIFF, NOAA KAP/BSB), other formats and raster encodings may or may not work. Please post to the nutiteq-dev list if your data did not work, and give us your data sample.
