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.A 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').Gilchrist Beachorthoantc1206_f50, f51, f52, f53Fairchild Beachorthoantc1209_f209, f210, f212Skua Beach/Stephenson Moraineorthoantc1209_f217, f218, f221, f223, f226Scarlet Hillorthoantc1202_f32, f34, f36Skua/Stephenson Moraineorthoantc_f226Spit north and Spit southorthoantc_f230, f232, f233, f240, f242orthocasc9495_f15Paddick Valleyorthoantc_f251, f252orthocasc9495_f17Winston Lagoon/Capsize Beachorthoantc1209_f260, f261, f263orthoantc1206_f247South Barrier/Lambeth Blufforthoantc1209_f263, f264, f266, f267, f268, f269, f271Lavett Blufforthoantc1209_f282orthoantc1207_f030, f032, f033Long Beachorthoantc1209_f285, f287, f289, f291, f293, f295orthoantc1207_f20-f29 (mosaic)Cape Arkona/Cape Pillarorthoantc1209_f303-f315 (mosaic)orthoantc1208_f046, f047Henderson Blufforthoantc1209_f320Walsh Blufforthoantc1209_f327-f328 (mosaic)orthoantc1208_f11-f17 (mosaic)Cape Gazertorthocasc9495_f63Laurens Peninsula/Atlas Covephoto_mosaic_laurens_or (mosaic of nine casc9495 frames coveringLaurens Peninsula and Atlas Cove area).
