Access
UNRESTRICTED
This data set is only available for a restricted user group, please contact us if you want to access these data.
RESTRICTED only accessable in CEN/MPI net or via CliSAP login What does that mean?
Data access via file system /data/icdc/land/modis-srtm_landwaterdistribution
or via email: ICDC
The map to the top right shows the distribution of the MODIS tiles. For each tile containing some land a data set is available. "h" and "v" allow the orientation on this map and are required to obtain the land-water-distribution of the region of interest; tile h18v03 covers the North Sea region, for example (see map to the bottom right).
Similar to topography and land information this data set is not visualized in the LAS.

Description
The data set contains a new, high resolution (250 m) data set of the land-water distribution. This data set is primarily based on results of the Space Shuttle Topographic Mission (SRTM) for the region 60°S to 60°N, on global 16-day composites of TERRA-MODIS and AQUA-MODIS data for 60°-90°N, and on the Mosaic of Antarctica (MOA). Gaps in the region covered by SRTM are filled with MODIS data also.
A brief description of this data set and the advance compared to earlier versions is given in the Users Guide.
Coverage, spatial and temporal resolution
Period and temporal resolution:
- none, 1 data set only

Data quality
Data quality was checked through comparison with in situ observations and independent, finer resolved air- and space-borne sensors (e.g. LandSAT and ASTER), see below and references in the Users Guide.
The data set includes information about where which main data source has been used and where original data might have been modified.
