An automated methodology for the inventory of wetlands in Uruguay was designed, defining
a specific technical criteria for their determination. It was necessary to use a combination
of procedures and technological tools (Remote Sensing, Digital Photogrammetry,
GIS) to process the available information. The following data has been considered: very
low sloped terrains (out of a digital terrain model), soils with characteristical moisture behavior,
basins and areas with hydrophile vegetation (using satellite images classification).
All these variables have been combined in a categorization algorithm to produce specific
thematic cartography.
