Geographic bounding box of a data file

This example prints the bounding box of a GeoTIFF image. The pixel values are not read, only the GeoTIFF file header is read. If the file contains many images, the bounding box of each image is printed.

Direct dependencies

Maven coordinates	Module info	Remarks
`org.apache.sis.storage:sis-geotiff`	`org.apache.sis.storage.geotiff`

The EPSG dependency may or may not be needed, depending how the Coordinate Reference System (CRS) is encoded in the GeoTIFF file.

Code example

The file name in following code need to be updated for yours data.

import java.io.File;
import org.apache.sis.storage.Aggregate;
import org.apache.sis.storage.DataStore;
import org.apache.sis.storage.DataStores;
import org.apache.sis.storage.DataStoreException;
import org.apache.sis.metadata.iso.extent.Extents;
import org.apache.sis.storage.Resource;

public class GetBBOX {
    /**
     * Demo entry point.
     *
     * @param  args  ignored.
     * @throws DataStoreException if an error occurred while reading the data file.
     */
    public static void main(String[] args) throws DataStoreException {
        try (DataStore store = DataStores.open(new File("Airport.tiff"))) {
            System.out.println("For the whole file");
            System.out.println(Extents.getGeographicBoundingBox(store.getMetadata()));
            if (store instanceof Aggregate agg) {
                for (Resource component : agg.components()) {
                    System.out.println("For component " + component.getIdentifier());
                    System.out.println(Extents.getGeographicBoundingBox(component.getMetadata()));
                }
            }
        }
    }
}

Output

The output depends on the data and the locale. Below is an example:

For the whole file

  ├─East bound longitude…… 2°34′15.75923342244″E
  ├─South bound latitude…… 48°59′20.7793385101″N
  ├─North bound latitude…… 49°01′07.5236778991″N
  └─Extent type code……………… True
