Heard Island: baseline data for monitoring longterm change. (c) Orthophotos used for vegetation mapping.

The vegetation mapping project used a set of 1987 and 1980 orthophotos and orthophoto mosaics for mapping and screen-digitising (see "Quality" section). Contact AADC for access to these. A shapefile of orthophoto coverage shows polygons for the areas where each orthophoto was used for mapping. This is an essential guide for use when matching the vegetation polygons to the correct orthophotos.\r\n\r\nA list of the orthophotos and orthophoto mosaics used for the vegetation mapping, with locations, is as follows: ('orthoantc' signifies 1987 series, 'orthocasc' signifies 1980 series. Run numbers are not included. Frame numbers are signified by 'f').\r\n\r\nGilchrist Beach\r\n\r\northoantc1206_f50, f51, f52, f53\r\n\r\nFairchild Beach\r\n\r\northoantc1209_f209, f210, f212\r\n\r\nSkua Beach/Stephenson Moraine\r\n\r\northoantc1209_f217, f218, f221, f223, f226\r\n\r\nScarlet Hill\r\n\r\northoantc1202_f32, f34, f36\r\n\r\nSkua/Stephenson Moraine\r\n\r\northoantc_f226\r\n\r\nSpit north and Spit south\r\n\r\northoantc_f230, f232, f233, f240, f242\r\n\r\northocasc9495_f15\r\n\r\nPaddick Valley\r\n\r\northoantc_f251, f252\r\n\r\northocasc9495_f17\r\n\r\nWinston Lagoon/Capsize Beach\r\n\r\northoantc1209_f260, f261, f263\r\n\r\northoantc1206_f247\r\n\r\nSouth Barrier/Lambeth Bluff\r\n\r\northoantc1209_f263, f264, f266, f267, f268, f269, f271\r\n\r\nLavett Bluff\r\n\r\northoantc1209_f282\r\n\r\northoantc1207_f030, f032, f033\r\n\r\nLong Beach\r\n\r\northoantc1209_f285, f287, f289, f291, f293, f295\r\n\r\northoantc1207_f20-f29 (mosaic)\r\n\r\nCape Arkona/Cape Pillar\r\n\r\northoantc1209_f303-f315 (mosaic)\r\n\r\northoantc1208_f046, f047\r\n\r\nHenderson Bluff\r\n\r\northoantc1209_f320\r\n\r\nWalsh Bluff\r\n\r\northoantc1209_f327-f328 (mosaic)\r\n\r\northoantc1208_f11-f17 (mosaic)\r\n\r\nCape Gazert\r\n\r\northocasc9495_f63\r\n\r\nLaurens Peninsula/Atlas Cove\r\n\r\nphoto_mosaic_laurens_or (mosaic of nine casc9495 frames covering\r\n\r\nLaurens Peninsula and Atlas Cove area).
