Massachusetts Bay Map Wins at USGS GIS Conference
The fourth biennial USGS GIS Conference was held this year April 23rd-27th in Denver, CO.
The conference, titled "GIS 2001: A Geospatial Odyssey," was a big hit among the several USGS
disciplines. Hands-on workshops, presentations, discussions, a poster session and vendor
displays were plentiful. Several workshops given by software vendors presented new and
upcoming software products and upgrades. The presentations ranged from policy issues to
voice-recognition software demonstrations.
Laurie Serrett and Laura Hayes (WHFC) presented
a new map of Massachusetts Bay, based on recent multi-beam surveys, in the poster session.
The color scheme used to code the bathymetry allowed the depth to be viewed in 3-D using
ChromaDepth™ glasses. The map shows a new detailed view of the sea floor based on multi-beam
observations at 10-m resolution, in contrast to historical, widely spaced soundings.
GIS conference participant using 3-D glasses views the color-coded bathymetric map of
Massachusetts Bay based on new multi-beam data and historical soundings. The multi-beam
data were collected cooperatively with the National Oceanic and Atmospheric Administration
While socializing and observing posters, participants voted for a dozen or so posters in several
categories, both serious and comical. Categories included "best analytic," "most nauseating
color," "most socially relevant," "you make us proud to be geeks," "space hog," "wow, how do
I get on this project!" and "on the verge of losing their cartographic license."
The map of Massachusetts Bay became known as the Massachusetts Bay "3-D" map and was selected as
a winner in the "best use of color" category. After several months of trying different color
schemes to make the map both visually pleasing and appropriate for the 3-D glasses, it was
rewarding to find that the result was well received by Denver conference attendees!
