Coastal Water and Coastline

Coastal WatersCoastal WatersOk, the problem with the gaps between the coastline and the coastal waters has been solved. Here is the shapefile which fits smoothly with the country template or the coastline file.

GEBCO – Bathymetry

GebcoGebco – General Bathymetric Chart of the Oceans – offers a finer resolution of the bathymetry as the Etopo2 at 1-minute. Here is the GRID-download.

Coastal Waters

ShelfDon’t know if this causes trouble for your calculations or if the calculation gets too inexact: Due to the pixel-based origin of the coastal waters data set, there are “empty cells” close to the coastline… Just so you are aware of it…

Global Change Master Directory Search

Data SearchThis site is a pretty good search engine for all kinds of data sets (Runoff, Precipitation, Agriculture, etc.). So in case you look for something, try this search too.

Atlas of the Biosphere

Atlas of the BiosphereThere are some interesting data sets on this site, not too actual in most cases, but nevertheless eventually useful, as for example: another data set on “Built-up land”, “Irrigated Lands”,?Ã?¬â?  some more soil data, “Suitability for Agriculture” and others.

Please let me know which data we should include.

Global Land Use Database

Wednesday, December 6th, 2006

Global Land Use DatabaseSAGE has been developing global databases of land use and land cover by combining satellite data and census data. This website provides access to our datasets of the distribution of the world’s natural vegetation, croplands, grazing lands, major crops, etc.

Of use for you (especially the croplands and grazing lands data)?

Coastline

ShorelineThe existing country template is a somewhat generalized version. Here is a higher-resolution coastline (with countries break-up for the moment). The snapshot above shows the difference between the two (the red one being the new data set). It’s a couple-of-kilometers-stretch at the western spanish coast.
