Resource analysis applications in Michigan

During the past two years, available NASA imagery has been applied to a broad spectrum of problems of concern to Michigan-based agencies. These demonstrations include the testing of remote sensing for the purposes of (1) highway corridor planning and impact assessments, (2) game management-area information bases, (3) multi-agency river basin planning, (4) timber resource management information systems, (5) agricultural land reservation policies, and (6) shoreline flooding damage assessment. In addition, cost accounting procedures have been developed for evaluating the relative costs of utilizing remote sensing in land cover and land use analysis data collection procedures.

Resource inventory for multi-agency watershed planning

A demonstration study showed that NASA high-altitude color infrared (RB-57) imagery is useful for providing timely, relatively inexpensive, and accurate land-use information. The inventory encompassed 18 land-use categories for a 2590-square-kilometer Michigan watershed. The RB-57 photography was compared to alternative data collection methods (including ERTS and Skylab) and was found to have superior cost effectiveness for providing the desired information.

The use of color infrared photography for wetlands assessment

A study was undertaken of Pointe Mouillee Marsh, located on Lake Erie, to assess shoreline erosion and to inventory and evaluate adjacent land as potential replacement for areas lost to erosion, and to provide better data sources for management decisions. The results of the study were: (1) Evaluation of low altitude oblique photography was useful in determining specifications of operational mission requirements; (2) Accurate base map revisions, reflecting shoreline erosion, were made using aerial photography and a Zoom Transfer Scope; (3) An aerial land cover inventory provided data necessary for the selection of adjacent lands suitable for marshland development; (4) A detailed inventory of vegetative communities (mapped from CIR), was made for management decisions; and (5) A carefully selected and well laid-out transect was a key asset to photo interpretation and analysis of vegetation.
