<p>According to one embodiment, a computer -readable medium having computer- executable instructions, when executed by a computer is configured to request a National Imagery Transmission Format (NITF) file. The NITF file comprises a geo- spatially enabled image, associated metadata, and text annotations. A plurality of graphical overlays are retrieved from a metadata repository. The plurality of graphical overlays comprise additional metadata associated with the geo-spatially enabled image. Text annotations are extracted from the geo-spatially enabled image. A skeleton Keyhole Markup Language (KML) file is created. Metadata overlays for each type of metadata and text annotations are added to the skeleton KML file. Overlays for the text annotations are added to the skeleton KML file. An image overlay for the geo-spatially enabled image is added to the skeleton KML file. The skeleton KML file and all files associated with the metadata overlays and annotations are zipped into a zipped KML (KMZ) file. The KMZ file is uplaoded to a discoverable data store.</p> |
