Evaluation of Satellite-Based Impervious Surface Data for the Mid-Atlantic Region Using an Independently Collected, High-Resolution Validation Database
Satellite-based estimates of impervious surfaces are being produced for the entire United States as part of the U.S. Geological Survey's (USGS) Landsat-based National Land Cover Database...
Past and Future of Construction Equipment�Part IV
The development of construction equipment has followed the major changes in global transportation. In 1420, Giovanni Fontana was dreaming of and diagramming dredging machines. Development...
Surveying and Mapping: History, Current Status, and Future Projections
Since the founding of ASCE in 1852, remarkable changes have occurred in all areas of civil engineering practice, including surveying and mapping. Instruments employed in surveying and...
A Better Image
As new sources of satellite and aerial data emerge, and as imagery processing software becomes cheaper and easier to use, engineers are tapping remote sensing data's potential...
NAVSTAR Global Positioning System Surveying
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 28. This manual provides technical specifications and...
Beachscape Abstract
The Surfrider Foundation is currently developing a volunteer-based mapping program to document the physical characteristics, land use patterns, pollution sources, public access, erosion,...
Flight Path Precision
Air traffic delays at the four airports operated by the Port Authority of New York and New Jersey are among the most severe and costly in the nation. A study by the Port Authority proposes...
The SPRP Project: An Overview
The National Science Foundation's Office of Polar Programs (OPP), the lead agency for the U.S. Antarctic Program, has begun construction of a replacement station for the Amundsen-Scott...
Long-Term Streamflow Forecasting
(No paper) Technology is creating major impacts on water management decisions dynamics. Today emerging technologies, such as satellite rely of hydrological and meteorological data, improvement...
Tracking the Temblor
The earthquake that occurred in Izmit, Turkey, in August 1999�along a fault line that is similar to the San Andreas Fault in Southern California�has provided useful data to researchers...
Fran-Spotting
When Hurricane Fran slammed into the North Carolina coast last September, it ravaged a fragile barrier island system already torn up by Hurricane Bertha two months before. The result was...
Mapping with a Differential
A southern New Jersey landfill is using Differential Global Positioning System topographic surveying to cut costs and turnaround time on annual mapping and volume certification. Modern...
The 1995 Flood in Southeastern Norway?Operational Forecasting, Warning, and Monitoring of a 200-Year Flood
The southeastern part of Norway experienced during the 1995 spring the highest flood recorded since the devastating flood in July 1789. The snow storage was at the end of April 30 to 50...
Karst Water Inventories Using Thermography
An airborne thermal camera was used to locate springs, swallets, and caves in a karst watershed. The detector was an imaging infrared camera with a temperature sensitivity of approximately...
Real-Time Construction Staking
Surveying has changed from a profession in which one learned skills on the job and could even become licensed without a degree. Now firms are turning to high tech equipment using geographic...
Rapid Slope Monitoring
Use of inexpensive coaxial cable rather than inclinometers has cut the cost of monitoring slope movement at seven potential landslide sites in California. The method involved is called...
Navigation of an Autonomous Robot Vehicle
The U.S. Air Force has developed an autonomous excavator capable of performing a variety of tasks at various Department of Defense facilities. Common to all the tasks is the need for autonomous...
GPS-Based Control for Space Vehicle Rendezvous
The recent advent of Differential Carrier Phase Global Position System (GPS) sensing has made it possible to determine relative positions of GPS receiver-equipped systems to less than...
Using a Small Satellite Bus As a Dedicated Platform for On-Orbit CSI Experiments
Control-Structure Integration (CSI) technology will be needed for the success of many future space missions, however, this technology will not be seriously considered for use by program...
A Conceptual Study of A Solar Power Satellite Using Centrifugal Force
We studied the self deployable Solar Power Satellite (SPS) using centrifugal force in order to explore ways in reducing construction costs. We designed a 340 kW SPS, and studied the unfolding...
