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...
The Use of Thematic Mapper Data for the Identification and Analysis of Small Island Land Covers: The Case of Block Island
This paper describes the classification (unsupervised) of a portion of the Landsat Thematic Mapper (TM) scene covering Block Island, Rhode Island and surrounding waters. The Landsat system...
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...
Community Succession Modeling for Resource Management
The U. S. Fish and Wildlife Service is implementing community succession models to forecast the impacts of altered hydrological regimes on forested floodplains and coastal marshes. A pilot...
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...
Modern and Historic Mapping of Tidal Marshlands of San Francisco Bay, California
In this work, studies were made of two marshland sites shown on the old maps that presently remain subject to tidal action. For each site, historic maps dating from the 1850's were accurately...
Litigating the Invisible Boundaries of Tidelands and Wetlands
The author urges uniformity in standards for establishing the two invisible lines that are dominant in coastal law, i. e. , the main high water line and the wetlands line. A high degree...
Application of Geographic Information System for Hydrologic Investigation
The Illinois Department of Energy and Natural Resources is developing a geographic information system (GIS) under the federally funded Lands Unsuitable for Mining Program (LUMP). This...
Computer Techniques for Acquisition and Reduction of Cross-Section Data
DuPage County, Illinois, has initiated a county-wide stormwater management program for planning and flood mitigation purposes. Field data with horizontal and vertical control are obtained...
Data Base in Your City's Future?
The city of Bellevue, Wash. computerized its public works maps in 1979 because Bellevue was using the county's maps, and their updating wasn't keeping up with suburban growth. Now this...
Accounting for Every Pipe
The Norfolk Sanitary Sewer Inventory and Appraisal System contains individual records for each of the 20,000 pipe segments in the Norfolk sewer system. The data, assembled from construction...
Predicting Sinkhole Collapse
Sinkholes erupt when a cavern or opening in the limestone rock below opens up to the surface. Florida's sinkholes have received most U.S. attention recently, but sinkhole geology is found...
REMOTS Sediment Profiling at the Field Verification Program
Disposal of uncapped highly polluted Black Rock Harbor muds took place in April-May 1983 at a buoy located within the Central Long Island Sound Disposal Area in 62-66 feet of water. Baseline...
Computer Links Facilities Management, Mapping
Computerizing of map drafting alone was not cost effective, so electric and gas utilities are using their systems to aid in managing their facilities. This article is a case history of...
Map Uses, Scales and Accuracies for Engineering and Associated Purposes
This publication is designed to aid engineers and others in obtaining maps suitable for use in engineering and associated work. Such maps must have the proper contour interval, map scale,...
Journal of Surveying Engineering
The Journal of Surveying Engineering covers the broad spectrum of surveying and mapping activities encountered in modern practice. It includes traditional areas such as construction surveys, control surveys,...
Surveying and Photogrammetry Research Needs
An ASCE-National Science Foundation committee listed and prioritized research needs in surveying and photogrammetry. Among them are the Department of Defense's Global Positioning...
Sanitary Sewer Design
Good sanitary sewer design practice requires evaluation of alternative locations, slopes and pipe sizes. However, cost considerations generally keep alternative evaluations to a minimum....
From Field to Map�Untouched by Human Hands
After a few years of experience with computerized surveying systems, surveyors are finding that increased efficiency and accuracy are justifying capital expenditures. Several users of...
