EARTH-MONITORING SATELLITES: Will the U.S. Bring Down the Curtain on Landsat?
Science (New York, N.Y.)
|September 5, 2007
Summary
New Landsat 7 satellite images show improved quality. However, researchers are concerned about the future of earth-monitoring satellites after 2006, as government plans shift to private industry successors.
Area of Science:
- Earth observation science
- Satellite technology
Background:
- The Landsat program, initiated in 1972, has been a cornerstone of global environmental monitoring.
- Landsat 7, a recent addition, provides enhanced imagery crucial for scientific research.
Purpose of the Study:
- To highlight the advancements in image quality from the Landsat 7 satellite.
- To address concerns regarding the continuity of earth observation capabilities beyond Landsat 7's operational lifespan.
Main Methods:
- Analysis of image data from the Landsat 7 satellite.
- Review of governmental plans and timelines for future satellite missions.
Main Results:
- Landsat 7 is delivering significantly improved image resolution and data quality.
- There is uncertainty surrounding the development and deployment of a suitable successor satellite.
Conclusions:
- While Landsat 7 represents a technological leap, its potential lack of a successor poses a risk to long-term earth monitoring.
- The transition of satellite management to private industry requires careful consideration to ensure data continuity and scientific access.

01:29Topographic Surveying and Contours
Topographic surveying is critical for documenting the Earth's surface, focusing on capturing elevations, slopes, and natural and man-made features. It is essential in construction planning, water resource management, and land-use analysis. The primary outcome of such surveys is a topographic map, which uses contour lines to visually represent the shape and slope of the terrain, providing valuable insights into the landscape's characteristics.Contour lines are fundamental to understanding the...
01:30Introduction to Global Positioning System
The Global Positioning System (GPS) revolutionized positioning on Earth, providing precise location data through satellite ranging. The GPS system was developed in 1978 by the U.S. Department of Defense for military use, and it became available for civilian applications in 1983, transforming fields including navigation, fleet management, and time synchronization for telecommunications systems.GPS consists of satellites in medium Earth orbit, about 20,200 kilometers above the surface,...
01:28Geoid and Ellipsoid
The Earth's shape is best described as an ellipsoid, a slightly flattened sphere created by rotating an ellipse around its minor axis. This flattening results in the polar axis being about 21 kilometers shorter than the equatorial axis. In contrast, the geoid represents the Earth's gravitational shape and aligns with the mean sea level (MSL). The geoid is an irregular equipotential surface where gravity is perpendicular at every point. Variations in Earth's mass distribution cause geoid...
01:30Types of Global Positioning System Surveys
GPS surveying methods vary in application, accuracy, and data collection techniques, catering to diverse surveying and mapping needs. Static GPS, kinematic GPS, and real-time kinematic (RTK) surveying are widely used. Each technique offers distinct advantages.Static GPS involves placing one receiver at a known reference point and another at the target point. It collects exact positional data by observing multiple satellite ranges over an extended period, achieving centimeter-level accuracy for...
01:30Design Example: Identifying the Locations of Monuments in the Field Using Global Positioning System Device
Surveyors use Global Positioning System (GPS) technology to measure the precise location and elevation of points on Earth. In a recent survey, GPS receivers were used to determine the coordinates and elevations of two park monuments. The process involved careful mission planning, data collection, and correction to ensure accuracy. The survey began with mission planning to identify optimal satellite visibility and minimize Position Dilution of Precision (PDOP). A geodetic control point served as...
