REMOTE SENSING OF ENVIRONMENTAL IMPACT OF LAND USE ACTIVITIES

Aircraft and spacecraft multispectral scanning sensors have increased substantially the capability to monitor land cover over that associated in the past with aerial film cameras and radar systems. A proposed Thematic Mapper with greater spectral and spatial resolutions for the fourth Landsat will usher in new environmental monitoring capability. In addition, continuing improvements in image classification by supervised and unsupervised computer techniques are being operationally verified for discriminating environmental impacts of human activities on the land. The benefits of employing remote sensing for this discrimination as opposed to more traditional ground sampling methodologies have been shown to far outweigh the incremental costs of converting to an aircraft-satellite multistage system. An example of land impact assessments are the Central Atlantic Regional Ecological Test Site (CARETS) by the U. S. Geological Survey. Other examples are included in the discussion.
