National Wetlands Inventory Mapping for San Francisco Bay/Delta Area, California
The U. S. Fish and Wildlife Service's National Wetlands Inventory Project (NWI) completed wetland mapping in 1982-83 for the San Francisco Bay/Delta area of California using mid-1970's...

REMOTS©: Reconnaissance of Benthic Environments
REMOTS(REGISTERED TRADEMARK) technology, a combination of sediment-profile photography and computer image analysis, was developed to address shortcomings in traditional benthic sampling...

The U.S. Geological Survey's National Real-Time Hydrologic Information System Using Goes Satellite Technology
The U. S. Geological Survey maintains the basic hydrologic data collection system for the United States. The Survey is upgrading the collection system with electronic communications technologies...

Satellites Monitor Eutrophication of Estuaries
In a study on eutrophication of estuaries, NOAA/AVHRR satellite data have been analyzed for the Changjiang River plume and the adjacent coastal areas. The different regimes identified...

Accuracy of Computed Water Surface Profiles
Stream cross-sectional geometry obtained from aerial surveys (aerial spot elevations and topographic maps) that conform to mapping industry standards are more accurate than is often recognized....

Satellite Remote Sensing for Regional Crop Inventories
LANDSAT 4 and 5 Satellite spectral images of the Columbia Basin were obtained during the 1984, 1985 and 1986 growing seasons by Cropix, Inc. of Hermiston, Oregon. A field classification...

Photogrammetric Analysis Using a Personal Computer
In many cases, photographs of the accident scene taken soon after the event contain visible evidence of road marks and/or debris. By the time the case reaches the accident investigator/reconstructionist,...

Terrain Analysis From Space Shuttle Photographs of Tibet
Several Space Shuttle missions obtained false color and large format, high resolution, black and white stereo photography at an approximate scale of 1:800,000. In addition to available...

Analysis of Alluvial Fan Flooding
Alluvial fans are estimated to cover approximately one third of the land area in the southwestern United States. Because of their relatively gentle slopes and well draining characteristics,...

Orthophotoquad Mapping Program for Alaska
The U. S. Geological Survey (USGS) is the lead civilian mapping agency in the United States and is responsible for creating and maintaining numerous map series. In Alaska the standard...

Hydraulic Profile Computation Using CADD
The data preparation can also be performed by directly recording onto a computer tape the aerial survey cross section ground points and the field survey work. A computer program can then...

Development of a Computerized Wetlands Mapping Data Base for Use in Section 404 Jurisdictional Determinatins in San Francisco Bay
Development and habitat alteration in the San Francisco Bay-Delta system have placed the remaining wetlands in jeopardy. The Bay-Delta wetlands will be mapped in a joint project of the...

Remote Sensing of Mangrove Areas on the Brazilian Coast
Remote sensing techniques are compared when applied on the survey of mangrove areas. The use of LANDSAT MSS scenes from channels 5 and 7, processed by interactive analyzer, allowed the...

Picture Index for Field Verification of Crop Coefficients
A picture index has been developed for eight irrigation crops to obtain reliable, rapid, and low-cost field determinations of crop growth stages and corresponding crop coefficient (Kc)...

Calendar: A 1985 Calendar of Bridge Photographs
Featured bridges are: Golden Gate Bridge (CA); Richmond . San Rafael Bridge (CA); Market Street Bridge (PA); Alsea Bay Bridge (OR); Longview Bridge (WA); Tyrone Bridge (KY); Newport Bridge...

Channel Migration on the Kansas River

As-Built Locations Through Precision Photography
