The groundwater pollution risk map is obtained by overlaying the DRASTIC vulnerability map with land use.

"Although the backdrop is a pattern," Ms. Colker said, "it's also meant to suggest antique navigators' maps, with lands and routes that may or may not exist.
For both soils, three areas under different land uses were identified within 'homogeneous' soil mapping units corresponding with land use classes generally available for regional hydrological model applications: grassland, crops and forest.
The major geomorphological units of a subregion of the Lena River Delta were mapped with a land form classification using a data-fusion approach of optical satellite imagery and digital elevation data to upscale SOC storage.
A comparison of this map with the land-use map (Fig. 5b) shows that SW and NW parts of the study area are mainly agricultural fields.
EEZs use knowledge of the land (e.g., soil fertility, slope, available natural resources), of existing economic uses, and of population centers, market demand, transport infrastructure, PAs, and so forth to produce landscape-scale maps with recommended land-use patterns.
Here, we investigate whether the outputs from these settlement mapping approaches can be integrated with land cover and census data to improve mapping accuracies over existing population distribution products.
The white areas within the map correspond to those with land uses other than agriculture in the Guapi-Macacu watershed.
The simulated maps were compared with land-use and land-cover maps, obtained from digital classification of remote sensing images, using the multiple resolution fitting procedure and a set of landscape structure measures, including fractal dimension, contagion index, and the number of patches for each type of land-use and land-cover class.
