Siuslaw to Umpqua Rivers
Layers of the map can be disabled but changes don't take effect until the next move or zoom. (Konstantin Gortinsky made me add this feature).
Please wait while I look up data for this map...
The older kayak icon appears wherever there is no route data and there is room to display one.
These generally appear above and to the left of the actual location,
so when you zoom in close enough they stay out of the way of the routes and images.
On a recent trip to Baja I noticed that my GPS was in a 'tracking' mode that laid down a few waypoints every so often while it was on.
This mode is supposed to be used to measure actual distance traveled but you have to leave it on all day for that to work.
I suspect this is a conspiracy with the Energizer Bunny to sell more batteries.
A fresh set of batteries only lasts 12 hours so I turn it on only occasionally.
It occurred to me that even these occasional track-points could be uploaded and assembled into an accurate record of my trip.
But how much memory does the GPS have before it has to start deleting the old points?
I used it sparingly but then when I arrived home I discovered over 3000 track-points in the GPS going back almost a year into several previous trips!
Now I turn the GPS on once an hour to let it lay down a few track-points for the map.
Where I have data like this, I convert it into routes in my database.
These are drawn as red lines on the maps.
Google does not notify me when you click on a line,
so I put small red knots at the 'corners' of the lines which can be clicked to get a link to the corresponding journal entry.
To switch over the map from using the kayaker icons to these new routes, I entered approximate track-points for many other long trips.
The images in my database are only located approximately. I entered positions
for images that were close enough to make them appear on the right proof page
by location. This typically put dozens of pictures all in one location in the
middle of each map. This should get you close to the correct location but you
will have to scroll around. Even the locations that look accurate may have been
created by clicking on a likely location on a map. I am currently working on
correcting all the image locations to more accurate positions but this will
take a while since there are over 8000 photographs.
I spent hundreds of hours building a static tree of maps for this WEB site.
In the early days there were no tools for building these and I coded the HTML by hand.
As the site grew it become a chore to maintain the links
between images, journal entries and maps.
I was searching for an automated way to do this when I discovered the map API
from Google. This works poorly on dial-up connections, but it allows me to build
automated maps for any location on the planet. I'll probably keep supporting the old
static map tree for a while, start using Google maps for new places I don't have maps
for, and eventually abandon all the work I did on the old maps.
