I'm working to expand the maps that I originally put together for the 46th District Democrats from the datafiles that Roger Crew has on the 41st District website. They use Google Maps and some modified shapefile data. All of King County's maps are available on 46dems.com and have been combined with the Election History records made available by Fred Morris. Rob Dolin has put up merged pages on kcdems.org. It's amazing what kinds of information is out there in the public domain, and all it takes is a plan to put things together into a useable format.
On April 2nd, Jason Copeland was able to get the shapefiles for the Snohomish County precincts, and Roger did his conversion to his Javascript data format. Getting these maps posted with a common interface is my next goal, and with Progressive Majority being willing to continue to fund the website hosting of Democracy for Washington, I finally have a home for them. I'll be working on these maps over the next few weeks.
I'm also having a lot of fun working with Google Earth. I found a converter that can take any shapefile opened in MapWindow GIS and save it as a .kml file for use in Google Earth and Google Maps. The first one that I put together is a map of where the Sound Transit Link Light Rail system will be going.
I'm running into some problems, mostly because I'm just starting with GIS, and a lot of the data that I'm finding is designed to work alone instead of playing nice with other datasets. For example, the Oregon Secretary of State has shapefiles for that state's House and Senate districts, but while the longitude points are accurate it's odd seeing Oregon show up just north of the Equator in the Pacific Ocean. I'm not sure how to fix that yet. I also found that the Census.gov shapefiles for the Washington State Congressional Districts from the 108th Congress show up as a tiny little map just below the equator. The 110th Congress datafiles are much better.
This page will provide links to the maps that I have put together, and I'll like to invite other GIS experts to comment. I need all the help I can get, and I really want to get the data, both maps and election history, from all of the other counties around the state.
