Borstad Associates Ltd. - Land Management

We have undertaken many terrestrial projects, including forest health, land use mapping, crop health, hazardous waste disposal, and reclamation of mined areas. Forestry projects include logging monitoring, acquisition of research data over deciduous forests affected by acid rain (Quebec), and studies of coniferous forests affected by root-rot (BC) among others.

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). In some instances, thematic maps are produced to support ecological studies. In other cases, CASI data have been used to delineate infestations, such in the Napa valley of California where vineyards had been affected by Phylloxera sp., and to detect subtle discolouration in vegetation, leading to the discovery of buried hazardous waste.

Watershed Management

	An Assessment of the Potential Contribution of Satellite Earth Observation to Watershed Management Program This report, prepared for the Canadian Space Agency, provides the results of a survey of ongoing and planned watershed management operations across Canada, together with an analysis of "who does what".
	Canda's Stewardship Agenda: The Role of Satellite Imagery in Watershed Management The objective of this short paper is to provide a non-technical introduction to the use of satellite imagery in watershed management and conservation. It contains a discussion of watershed management information needs, and potential role of satellite data. An appendix to the report contains a brief review of the pros and cons of using satellite imagery, sources of satellite data and costs.
	The Use of Landsat Imagery in Support of Watershed Management - A Reality Check In 2003, the Canadian Space Agency (CSA) asked Borstad et al to interview watershed managers across Canada to establish their interest in using satellite imagery in support of their various responsibilities.

Mapping Wetland Vegetation

Classification of Fraser River Wetlands: South Arm Marshes and Ladner Marsh

This thematic map of fish and wildlife habitat in the Fraser River estuary was produced for the Department of Fisheries and Oceans using CASI multispectral aerial imagery. This area provides breeding and feeding habitat for one of the largest overwintering waterfowl populations in Canada, comprising some 40 species of ducks, geese and swans. As well, it provides prime habitat for large numbers of fish and wildlife species. Yet the marshes are located adjacent to one of the fastest growing urban centres in the country and are subject to intense pressure from urban and agricultural development.

Multispectral Classification of Wetland Vegetation in the Rose Lake-Cataldo Region of Idaho

Produced as part of studies of acid mine drainage in the Coeur d'Alene River for the United States Geological Survey, this 3D view of the area was created by draping a thematic map produced from CASI multipectral data over a Digital Terrain Model.

Mapping Riparian Ecosystems

Maps of River Depth from Airborne Digital Imagery

The Horsefly River, in central British Columbia, is an important
salmon spawning stream. This map of water depth was produced
from digital multispectral imagery obtained from a small aircraft.

Change Visualization

Visulaizing the Changing Landscape with Satellite Imaging

Today, the Earth and its natural resources are often viewed in
the context of ownership, management and sustainability.
Borstad Associates Ltd. offers satellite image-maps that
describe the present state of the landscape, its past,
changes over time, and even its future.
