| Lineage | The dataset was derived in ArcMap 10.0 using a Wave tool version 2008 developed by USGS found on Environment Systems system, available from http://www.umesc.usgs.gov/management/dss/wind_fetch_wave_models.html. A shapefile of the world obtained from www.gadm.org v1.0 was clipped to a fairly large extent around the island (~8 degrees East-West and ~24 degrees North-South). The shapefile was rasterised to 0.01 degrees i.e. roughly 1000metres. The fetch tool was run in SPM mode i.e. 9 x 3 degree rotation radials x 16 significant wind directions (from 0 to 360 degrees, step 22.5deg). The images show the patterns of distance (degrees) travelled by waves according to the shape of landmasses. For distances originating from the margins of images, increasing negative values are present until a landmass is encountered. Absolute value images for each fetch image for each wind direction were created to eliminate negative travel values. The final result is a weighed sum image of each fetch image for each of the 16 directions was performed (weights according to the annual mean wind distribution chart http://www.windfinder.com/windstatistics/mount_pleasant_falkland). |
