Land use map

Land use maps (Fig. 3) were provided by the CHE, for the years 1984, 1991 and 1995, at a 1 100,000 scale, and the land use cover of the year 1984 was selected as representative for the simulations referring to the control period (1961-1990). Table 1 shows the six major land use classes identified within the study area. Information on soil types provided by the Oficina de Planificacion Hidrologica (OPH) of CHE was used to assign the soil properties required by SWAT 2005. The original 136 lithological classes were first aggregated into 23 main classes, as...

Finally, data from studies in Seattle, Washington (.8) suggested a 10 to 20 fold increase in street dust emissions in heavy Industrial areas as compared to commercial, land use areas. Adjustments were made to each grid s emissions based on information from land use maps and detailed data on unpaved roads.

The name "tessera" (latin component of a mosaic configuration) can be correlated with the delimitations of the principal types of ecosystems (i.e. biogeocenosis or, better, ecocoenotopes) constituting a sort of geographic map, some times apparently similar to the "land use" maps of the human territory, but with an ecological sense.

The final stage of the algorithm involves data processing and data extraction from the maps which are compiled. In the course of this stage, the integrated base is created it contains all initial quantitative and qualitative information and also provides for the input of new data. For example, the overlay of the land use map on the map of physical landscapes allows one to obtain information about human-caused impacts on the land itself as well as ecological problems. 

Local governments allow building in urban land over high hazard areas because hazard maps are not taken into account in the land use maps (Fig. 43.2).
