For all you GPSers and others who might be interested: I've added town latitude and longitude coordinates to the database, which made it possible to add a few new features to the website.
Here's a page which summarizes
the latitude/longitude coordinates of Katy Trail towns, generally centering on the trailheads.
And if you visit the individual town pages, you'll see a new option above each town map, to view the map in Google Map format. This is simply an embedded Google map, which allows you to zoom and recenter the map. As an example,
here's the Rocheport page. If you page down you can see the Google-style map, the latitude/longitude values, and the dropdown list allowing you to switch between map formats.
There are pros and cons to each map format. With the graphic format you can easily see the trail and trailhead, and with the Google format you can use the zooming and centering features.
