Hello,
I'm developing an Android application and I'm trying to add a RasterLayer to may map containing a tif image. The map has web mercator 102100 as spatial reference and the spatial reference of the image is different (ED50 / UTM 30N). I have the .pfj, .tif and .tfw files in the same folder. This is my code to add the RasterLayer to my MapView:
String rasterPath = "<path to tif image>";
FileRasterSource rasterSource = null;
try {
rasterSource = new FileRasterSource(rasterPath);
rasterSource.project(mMapView.getSpatialReference());
RasterLayer rasterLayer = new RasterLayer(rasterSource);
rasterLayer.setOpacity(0.5f);
mMapView.addLayer(rasterLayer);
} catch (IllegalArgumentException ie) {
Log.d("IAE", "null or empty path");
} catch (FileNotFoundException fe) {
Log.d("FNFE", "raster file doesn't exist");
} catch (RuntimeException re) {
Log.d("RE", "raster file can't be opened");
}
When I run the application, the image is shown in a bad location. I think the problem is the API is not making the reprojection of the image. How does the API know the spatial reference of the image? Do I need to add any other file?
Thanks in advance
