The GOES-R satellite has two imaging instruments used for landmarking: the Advanced Baseline Imager (ABI) and the Geostationary Lightning Mapper (GLM). These instruments provide enhanced imagery with better spatial, spectral, and temporal resolution compared to previous GOES imaging instruments. The benefits of the improved imagery are lost without the correct geo-location of the data. Landmarking is used to validate the geo-location process. To more accurately measure the landmarks, the Shuttle Radar Topography Mission (SRTM) Water Body Data (SWBD) was chosen as a more up-to-date and accurate set of shoreline points than the set currently used for GOES-NOP. All the shoreline points for a 1° x 1° portion of the earth are maintained as a set of polygons in an ESRI shape file. A typical landmark requires the shoreline points within a 50 km square area. Based on the corner points of the landmark area, the corresponding shape file(s) are read to extract the data. This presentation illustrates the use of several Java libraries within the Playback and Display component of the Product Monitor software for the GOES-R series to provide an analyst with the ability to interactively generate a landmark from an image.
