| Popis: | International Telemetering Conference Proceedings / October 14-16, 1975 / Sheraton Inn, Silver Spring, Maryland LANDSAT data collection platforms have been interfaced with a variety of environmental and water quality sensors to test performance, reliability and versatility of the LANDSAT data collection system. Signal conditioning interfaces were required for sensors selected to measure: ground, soil and air temperatures; wind passage and speed; snow accumulation and ablation; pore water pressures; salinity; pH; dissolved oxygen; and water stage. System performance was found to be excellent; system reliability was high. Considering technical aspects only, exploitation of this satellite system for automated environmental and water quality data collection is hindered most by the relatively immature state of sensor and interface development. Notwithstanding, well prepared, two man field parties had no difficulty in deploying DCPs with their associated antennae and sensor subsystems in remote subarctic locations. Environmental data acquired at the various sites are being used in the assessment of the environmental impacts associated with the proposed construction of two hydropower dams on the Susitna River in interior Alaska, on the effects of impoundments over permafrost, and in assessing the effects associated with the construction and operation of the trans-Alaska pipeline. |
