Earth Resources Observation Satellite Image Utility at State Level

摘要

The utility of the proposed Earth Resources Observation Satellite (EROS) Program as an information source for operational state agencies and academic institutions has been explored in a one year study within the State of Washington. Operational personnel from most natural resources and land use oriented state agencies participated in the project. Research personnel from the University of Washington and Washington State University carried out studies of the imagery. High altitude, small scale photographs, both singly and in mosaic form, were used to simulate ERTS imagery. Participants were asked to relate their data needs to the proposed ERTS imagery and the timeliness of satellite surveillance. Resulting evaluation lead to some of the following conclusions: significant data use of ERTS imagery can occur at the state level; potential user knowledge of the availability of aerial photography and how to use it is poor; ERTS imagery simulation process used in this study was poor; and satellite relay ground sensor data would be of significance to many users. Recommendations are made in response to all conclusions. (Author)
