Constructor Detail

GdalMapLayer

public GdalMapLayer(com.nutiteq.projections.Projection projection,
            int minZoom,
            int maxZoom,
            int id,
            String gdalSource,
            com.nutiteq.MapView mapView,
            boolean reproject)
             throws IOException

Read raster data source using GDAL library. Tested with: indexed color: NOAA BSB RGB bands in GeoTIFF file (tested with Natural Earth geotiff as described in http://mapbox.com/tilemill/docs/guides/reprojecting-geotiff/) Data must be EPSG:3857, could be with VRT but then slower. Overviews suggested also

Parameters:

projection - map layer projection. Currently only EPSG3857 is supported

minZoom - minimum Zoom

maxZoom - maximum Zoom

id - caching ID, make it unique

gdalSource - file to be read, full path

mapView -

Throws:

IOException
