The Interactive Map Index

Click on the colored areas to get more detailed maps.

Clicking on colored areas of this map should lead you to more and more detailed maps until you can see kayak trails as red lines on the ocean. Clicking on these will bring up a kayak journal entry about each location along the coast.

I have been over some areas many times, with journal entries for each trip. In these places I have put in a pointer to my favorite story about the location, or the most recent journal entry. Usually the stories have links back to previous trips in the same location, so you can find out more about a spot if you are interested.

All these maps were built with client side maps, and may not work with older browsers.

A few of the maps came from the Xerox PARC Map Viewer. I stole several of the mid level maps from other sites. The most detailed maps (with a scale of 1:60,000) all came from the Tiger Mapping Service put on the WEB by the US Census Bureau. You may notice that the detail varies from map to map. Most of the inconsistencies are caused by bugs in the Tiger server software. I could not force this software to put highways and cities on the complete map of Mendocino County at first. (I sent them email about the problem and they fixed it for me)!

The Census Bureau has combined data from many different places to build these maps. The database of county borders is digitized at a much lower resolution than the shoreline. This results in maps that have sections of land painted ocean colors when the shoreline sticks out past the county "line" and sections of ocean painted county colors. I had to run along the shoreline in each map and correct these defects. Even the detail of the shoreline changes from place to place. For some reason the remote Mendocino Headlands is rendered in incredible detail while the cosmopolitan Angel Island is rendered as a mere dozen straight lines. As I corrected the shoreline problems I added more details from the USGS 7-1/2 degree topographic maps. This allowed me to put in all the major offshore rocks, and a smattering of pixels for fields of smaller rocks. I added labels for all the bays, coves, and points along the shore. And, of course, I added lines in the water indicating approximate paths of me and my kayak.

After all this work, I now consider the resulting bitmap-maps my own, although I am grateful for the Census Bureau for supplying the original data.
