THE PROJECT WILL: 1) CREATE AN ARCHIVE OF TIME-TAGGED HIGH-RESOLUTION DIGITAL ELEVATION MODELS (DEMS) DERIVED USING THE AMES STEREO PIPELINE (ASP) APPLIED TO SWATHS OF SUB-METER ALONG TRACK SATELLITE IMAGERY COLLECTED BETWEEN 2009 TO 2016. THE SPATIAL EXTENT OF THE DATABASE WILL MATCH THE SPATIAL EXTENT OF ARCHIVED AERIAL PHOTOGRAPHY OVER THE AP [FIGURE 1]. 2) CO-REGISTER THE SATELLITE DERIVED DEMS TO ICESAT AND OIB AIRBORNE TOPOGRAPHIC MAPPER (ATM) AND LAND VEGETATION AND ICE SENSOR (LVIS) LASER ALTIMETRY USING TIE POINTS OVER PROMINENT BEDROCK FEATURES EFFECTIVELY USING SPACEBORNE AND OIB ELEVATION RETURNS AS GROUND CONTROL FOR WORLDVIEW DEMS. 3) ORTHORECTIFY SUB-METER SATELLITE IMAGERY TO THE HIGH-RESOLUTION DEMS. 4) DEVELOP DEEP-LEARNING ALGORITHMS AND NEURAL NETWORKS TO AUTOMATICALLY CO-REGISTER AERIAL PHOTOGRAPHY TO ORTHORECTIFIED SUB-METER WORLDVIEW IMAGERY AND DEMS PROVIDING GROUND CONTROL FOR THE AERIAL PHOTOGRAPHY. 5) USE A TWO PRONGED APPROACH USING STRUCTURE FROM MOTION (SFM) ALGORITHMS AND ASP STEREO-PHOTOGRAMMETRY ASSISTED WITH THE GROUND CONTROL TO PRODUCE DEMS FROM MID-CENTURY AERIAL PHOTOGRAPHY. 6) PRODUCE ICE HEIGHT CHANGE TIME-SERIES AT MANY HUNDREDS OF LOCATIONS AROUND THE ANTARCTICA PENINSULA AND EXAMINE THESE FOR SPATIAL AND TEMPORAL PATTERNS THAT ARE INDICATIVE OF COMMON FORCING FACTORS. 7) PRODUCE MID-CENTURY ICE HEIGHTS TRIMLINES AND ICE MARGIN POSITIONS THAT CAN BE ASSIMILATED INTO COUPLED ATMOSPHERIC/ICE-SHEET MODELS.
