Abstract

The presented dataset EU-MOHP v013.1.1 provides cross-scale information on the hydrologic position (MOHP) of a geographic point within its respective river network and catchment as gridded maps. More precisely, it comprises the three measures “divide to stream distance” (DSD) as sum of the distances to the nearest stream and catchment divide, “lateral position” (LP) as a relative measure of the position between the stream and the divide and “stream distance” (SD) as the distance to the nearest stream. These three measures are calculated for several hydrologic orders to reflect different spatial scales from local to continental. Its spatial extent covers major parts of the European Economic Area (EEA39) which also largely coincides with physiographical Europe. Although there are multiple potential use cases, this dataset serves predominantly as valuable static environmental descriptor or predictor variable for hydrogeological and hydrological modelling such as mapping or forecasting tasks using machine learning. The generation of this dataset uses free open source software only and therefore can be transferred to other regions or input datasets.

Details

The EU-MOHP v013.1.1 dataset was developed and generated as part of the MACRO project.

This repository hosts the dataset EU-MOHP v013.1.1 as single GeoTIFF files with .tif file extension, but compressed to .7z files for download. Further details are listed as follows:

• File format: GeoTIFF
• File extension: .tif
• Compressed file extension: .7z
• Grid/raster cell size: 30m
• Temporal characteristic: static
• Coordinate Reference System (PROJ string): +proj=laea +lat_0=52 +lon_0=10 +x_0=4321000 +y_0=3210000 +ellps=GRS80 +units=m +no_defs
• Coordinate Reference System (EPSG): 3035

For more background information, see the corresponding publication of the data descriptor.

Download Instructions

The data descriptor also explains the file naming scheme. You can use the search bar above to subset the total dataset. The two following examples help defining a search term to subset the dataset for your study area or the required EU-MOHP measures or specific hydrologic orders by combining the the terms in the column Value of the table further down.

• Example 1: If you are interested in all measures of all hydrologic orders for the island Sardinia, enter italy2 in the search bar.
• Example 2: If you are interested in the measure lateral position (LP) of all hydrologic orders for the island Sardinia, enter italy2_lp in the search bar.

Note, however, that not every region or spatial coverage applies to all hydrologic orders. If you want to check more in detail whether your study area is covered by this dataset and which files are relevant, please use this interactive map.
