Landcover Mapping

Satellite imagery offers the potential to be able to characterize landcover over very large areas efficiently and very cost effectively. At Applied Analysis Inc., we produce landcover maps from satellite imagery based on the spectral properties of each pixel within a scene. By grouping pixels into classes with similar spectral properties and associating these classes with particular landcover types, it is possible to produce maps which delineate land cover and land use.

Landcover mapping is an excellent way to gain a synoptic view of a watershed or ecosystem. It can provide a clear picture of what is occurring in the terrestrial environment in order to effectively understand and correlate the relationship between the water quality issues and terrestrial land-use.

Some applications of landcover mapping using satellite imagery are:
· Environmental modeling
· Impervious surface mapping
· Environmental impact studies
· Non-point source pollution studies
· Land use studies
· Ecosystem analysis

At AAI we use both traditional whole-pixel terrain categorization and subpixel land classification depending on the application requirements. Following image georectification, the resulting landcover classification becomes a detailed map of land characteristics at every point throughout the study area.
