Coastal Distance


Citation Information

Title: Coastal Distance

Source: Shuttle Radar Topography Mission (SRTM) Ocean Layer

Date: 2000

Description: Jet Propulsion Laboratory, NASA.



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.
