Vegetation mapping and modelling
GIS and RS are being increasingly used in environmental
and landscape studies and in vegetation mapping and modelling.
- Integrating information from
remote sensing, aerial photographs and field surveys within a GIS allows
digital vegetation and land use maps to be produced for wide areas.
- GIS is particularly useful
for modelling ecosystem pattern since the characteristics of ecosystems
are determined by vegetation.
- GIS also provides the capability to map vegetation
pattern at different scales, thus enabling the hierarchical nature of
ecosystems to be investigated.
