We used aerial photography combined with field observations to develop a detailed aquatic vegetation
map for Netley-Libau Marsh in south-central Manitoba. This report describes the creation of a new
geographically accurate map (georeferenced for use in a Geographic Information System - GIS), based
on aerial photos taken in 2001, and construction of a detailed vegetation map for evaluating the changing
state of Netley-Libau Marsh. This provides a basis for comparison with a 1979 vegetation map enabling
a quantitative assessment of changes in the marsh over a 22-year period.
