Abstract
Abstract: Environmental Monitoring of International and Domestic Operations
Using Remote Sensing
By
Texaco Inc., Houston, TX
Satellite and aircraft remote sensing is a
cost-effective technology for environmental
assessment and monitoring. Satellite and
airborne digital and photographic data are
used for this purpose. Aerial photographs
date back to the 1920s, and satellite images
to 1972. These data are used to document
environmental conditions that existed at a
moment in time (a "baseline"), typically
before the occurrence of some event (beginning
of oil field operations, urbanization, spills, etc.). This documentation serves
as a benchmark
against which future
changes can be compared and quantified.
Typically, land cover and land use, existing
environmental conditions, geologic
hazards, water quality, and archeological
sites are evaluated. Changes in the environment
are then monitored at regular intervals
throughout the operational cycle.
The application of remote sensing technology to environmental assessments and monitoring will be shown in examples of: 1) deforestation in South America, 2) hydrocarbon spill detection, 3) vegetation re-growth pattern in wetlands after seismic surveys, 4) land use and agricultural changes in developing countries, and 5) seismic survey designs in the central U.S.
