ACTUAL COST DEPENDS! ISSUES TO CONSIDER IN COST
Programmed or Archive Shared purchasing - common
areas of interest Negotiated contracts versus
list price - economies of scale, WALIS
SLICP Coverage - Regional Mosaics, single
image Information needs - Vegetation,infrastructur
e,change detection Spectral
bands Scale/Resolution really needed

Land Monitor Project
The Land Monitor Project is a joint project
between seven agencies. It provides access to
Landsat satellite image mosaics, salinity maps,
vegetation maps, digital elevation models and
other map datasets. The project covers the
south-west of Western Australia's agricultural
area. For more information please visit the
