Putting Cancer Alley on the Map
Report #1, June 22, 2002
As a demonstration of how SVG can be used for citizen
mapmaking, we invite you to join us midstream in a project --
putting Cancer Alley on the map of Louisiana.
If you have an
appropriately configured system (see the sidebar to the right), you can check the
map out
here.
"Cancer Alley" is a term coined in the 1980s by Louisiana
activists Darryl Malek-Wiley and Richard Miller to describe a
pollution-ridden industrial corridor that is home, by some
counts, to over 300 major industries. Louisiana development officials and industry
supporters dispute the cancer association, claiming the
area's cancer rates are typical of the rest of the country.
The Cato Institute, for example, has called Cancer Alley an
"environmental myth". For residents of the area, however,
physical ailments are anything but mythical. As Barbara
Koeppel noted in her piece in The Nation, "People living
nearest the factories and waste dumps are sick and dying.
Clusters of asthma, stillbirths, miscarriages, neurological
diseases and cancers have mushroomed". Undoubtedly,
scientifically reliable health analyses confirming the
existence of "Cancer Alley" would help residents to advance
their claims. According to Koeppel, such studies have been
hampered, in part, by deficient data classication and sloppy
record keeping at the state's Tumor Registry ( "Cancer Alley,
Louisiana", The Nation, November 8, 1999).
We clearly sympathize with the residents and advocates for
whom the term "Cancer Alley" has acquired popular legitimacy.
This project -- putting Cancer Alley on the map -- aims to
give voice to local complaints, visually associating health
experiences with specific geographic locations.
If you have downloaded and installed your SVG viewer from
Adobe's SVG download site (see right sidebar), you can see that we have already
built a map of the year 2000 Toxics Release Inventory reporters in Louisiana. Included are layers for Congressional
districts and State Senate districts along with contact
information. (We have produced a State House districts layer
but wish to reduce the large file size before including it).
In the southeastern portion of the state, the shape of Cancer
Alley stands out conspicuously, starting in the area south of
New Orleans along Lake Pontchartrain, running along or
parallel to the Mississippi in a northwesterly direction
toward Baton Rouge.
The next steps required in order to put Cancer Alley on the
map include:
associating information from already published
reports and studies with locations on the map.
conducting an
environmental justice analysis of the Cancer Alley area using
the methods recommended by the Environmental Protection
Agency. Census blocks within a one-mile radius of polluting
facilities whose population is over 50% minority or 50%
low-income can be designated as environmental justice cases.
We expect this designation to fit many of the predominantly
low-income, African-American communities in this area.
gathering and incorporating information on elected officials'
voting records and campaign contributions as they relate to
environmental health. Eventually, handheld Geostationary
Positioning Systems (GPS) could be used to identify the
latitude and longitude coordinates of problems identified
during door-to-door community health surveys.
In the coming reports, I will cover:
specifics of conducting
and mapping an environmental justice analysis of Cancer
Alley.
'how-to' information on building the Louisiana map
posted here. The political district map data came from the
U.S.
Census Boundary Files and the TRI data from RTK Net.
With some database programming skills (or utilities of the
sort we eventually hope to provide) and a few SVG tips, you
can master the data preparation part of it and reproduce such
maps for any state without much difficulty. If you are a code
detective of any sort, you can already figure out a lot by
saving the two files (LA_TRI2000.svg and Info.svg) used with
the Louisiana map as well as this JavaScript file (last
updated on 7/4/02).
ways that you may be able to help put
Cancer Alley on the map with information-gathering and
specific SVG development tasks.

SVG Viewer Required
In order to view the Louisiana TRI/Cancer Alley, you must install
the free Adobe SVG viewer. First, download the "SVGview.exe" file from the Adobe site.
Note the directory where you saved the file, find
the file and double-click on it to install. This makes your browser
SVG-ready.
Known issues:
It appears that this map can only be viewed on PCs using
Microsoft Internet Explorer 5.0 or higher. The JavaScript being
used apparently will not work with Netscape Navigator.
