STRUCTURE OF AEZ
The structure of AEZ includes the comprehensive framework for the
appraisal and planning of land resources (Figure 1). The nature of analysis,
which involves the combination of layers of spatial information to define zones,
lends itself to application of a GIS. The major requirements of computerized
GIS for an activity like agro-ecological zoning and zonal resource information
of mountain areas are topographic maps, land resource maps and contour maps.
These maps, containing physiographic, geographic, and bio-climatic
information form primary inputs. Various outputs are generated in both
tabular and map forms. Till date, good progress has been made in developing
GIS based tools for land resources planning, management and monitoring at
different scales.
