Creating a Very Large Area DTM for Universal Access

Stability of a Geodesic Dome Under Symmetric Dynamic Loads

Keynote Address Third North American Conference on the Management of Water Resources

A GIS Foundation Example
A primary network of geodetic control monuments was developed with static GPS measurements. These monuments are tied to the existing Florida High Precision Network....

OTF Kinematic GPS Positioning for Vertical Reference Datum

3-D Coordinates - A Universal Rectangular Coordinate System for a GIS and Other Spatial Databases
Rules of solid geometry and 3-dimensional (3-D) rectangular coordinate systems are well known and used in many applications. Points on or near the earth's surface have long been described...

Hyper-Geodesic Structures: Excerpts from a Visual Catalog
A class of hyper-geodesic surface structures is presented. The surfaces of known polygons, polyhedra, plane and space tessellations, higher dimensional polytopes can be subdivided into...

Explorations in Geodesic Forms
Geodesic forms constitute an important family of structural systems. The objective of the paper is to show how the concepts of a mathematical tool called formex algebra and its programming...

Inertially Favorable Trajectories for Robot Motion in Space
Robot manipulators generally display non-linear coupled dynamic forces which increase with speed. Efficiencies can be achieved by finding trajectories which take advantage of those inertial...

Historical Atlas of Tidal Creeks, San Francisco Bay, California
Historic widths and depths of 69 major tidal creeks in San Francisco Bay were studied from maps dated from 1852 to the 1980's. Survey maps by the U.S. Coast Survey (and successors, U.S....

Challenges Associated with Metriciation of the Nautical Chart
Under the Metric conversion Act of 1975, Omnibus Trade and Competitiveness Act of 1988, and Executive Order 12770 of 1991 all federal agencies are required to convert to the international...

The Wetted Bound: The Missing Link between Surveying and Planning?
Aerial photographs of the coastline are useful tools for investigating historic shoreline changes, especially in locations where such photographs are available back to the late 1920's....

Measurement of Bridge Scour at the SR-32 Crossing of the Sacramento River at Hamilton City, California, 1987-92
A study of the State Route 32 crossing of the Sacramento River near Hamilton City, California, is being made to determine those channel and bridge factors that contribute to scour at the...

Establishing a Geographic Information System
The ultimate test of an advancement in civil engineering is the successful integration of aspects of the advance into the general engineering community. Success stories in this area include...

Keys to High-Accuracy Mapping of Shoreline Changes
For many years it has been difficult to overlay maps and aerial photographs with different scales and publication dates using conventional techniques. Large processing errors also made...

Aerial Videotape Mapping of Coastal Geomorphic Changes
An aerial geomorphic mapping system was developed to examine the spatial and temporal variability in the coastal geomorphology of Louisiana. Between 1984 and 1990 eleven sequential annual...

Surveying and Geodesy in the Exploration and Production of Oil and Gas

The Potential Realtime Application of GPS Phase Tracking in Construction Surveying
The potential use of precise Global Positioning System (GPS) phase tracking receivers in a realtime application is discussed in relation to the advancements to date in precise kinematic...
