ASL Remote Sensing

Forestry and Land Management

At ASL Borstad we have undertaken a wide diversity of land management projects, including forest health, land use mapping, crop health, and watershed management.  Our multispectral imagery has been used as the prime data source in many land assessments, such as the Lake Victoria Environmental Management Project (Kenya), and the Coffee Wilt Project (Uganda).



Some of our forestry projects have included logging monitoring, acquisition of research data over deciduous forests affected by acid rain (Quebec), and studies of coniferous forests affected by root rot (British Columbia), among others.

CASI data have been used to delineate insect infestations, such as in the Napa valley of California where vineyards had been affected by Phylloxera sp., and to detect subtle discolouration in vegetation due to nutrient deficiency or disease.

Watershed management

The long time series now available for sensors such as Landsat and AVHRR permit change detection and trend analysis.  Climate-related changes can be separated from those due to fire, disease, logging or urbanization.

Land use

High resolution satellite imagery provides excellent base layers for urban planning GIS.
