Description

Distance (km) from coastline calculated using SRTM Ocean Layer in which distance is zero for any cell that is completely ocean. Native data is vector polygon format projected in Geographic Coordinate System WGS 1984.

Processing Procedure

1. In ArcMap 10.o, merge SRTM polygon tiles (GTOPO30 Water (1-6), SRTM Water (1-6)).

2. Convert native data into 30 arc second resolution grid.

3. Use ‘cost distance’ tool to calculate distance to coastline.

4. Use zonal statistics to calculate mean values within each GLU.
