Abstract Global Coastline v1 is a global map at 1 arc-second of resolution (approximately 30 meters at the equator) defining which areas of the earth are land and which are ocean or sea. Global Coastline v1 was created by ISCIENCES, L.L.C., Ann Arbor, Michigan. The dataset was produced using USGS SRTM Water Body Data, with corrections; and NOAA World Vector Shoreline data for areas above 60 degrees north, outside of the SRTM coverage area. Global Coastline v1 provides a greater degree of accuracy within the SRTM coverage area. Future updates are planned to improve accuracy in non-SRTM covered areas. Global Coastline v1 dataset contains the same coastline definition as both a map mask (polygons) and as a map outline (line-based vector data layer). The image above shows the global vector at 30 arc-sec. (Click on the thumbnail to view a 1 arc-sec image: Global Coastline v1 one arc-sec vector data is shown in yellow, VMAP0 in cyan, and World Vector Shoreline in red, over an image from NaturalVue (MDA Federal) of a tiny island west of Sumatra.)
Supplemental Information The free downloadable zip file (8.1 MB) contains a 1km (30 arc second) map. Commercial and research licenses are available for the 90 meter map (3 arc second) and 30 meter map (1 arc second). Contact info@isciences.com or call 734.214.9810. The zip file contains the same data coverage as both a map mask of ESRI shapefile closed polygons, and as a map outline of non-closed line segments (line-based vector data layer). For more information about this map see below: Distribution Info>Data for Download>Map Guide and Distribution Info>OnLine Resource>Data Project Narrative.
Purpose ISciences developed this dataset to provide a global land/sea mask that closely matches modern high-resolution raster datasets. ISciences Coastline Data has the advantage of high resolution, excellent co-registration, and is complete, without gaps due to data voids.
