<p>Jerry,</p>
<p>I just finished getting your CDTA data into Excel, extracting the segments, mileage, descriptions...etc...and was able to create 8 GeoRSS xml files (Bing import) and 8 kml files (Google Earth/Maps)...</p>
<p>In doing so, I noticed that waypoints in CO were named differently (no segments)...and no Altitude values were given at all for all states. I could be wrong...but any reasons for this?</p>
<p>Also, this is called the "official" CDTA route so I'm guessing you pulled most of your paper maps from them. How much face to face time did you need/get with the Forest Service/BLM to fill in any gaps when logging this data? Did you work for the CDTA or were you hired by anyone to do this?</p>
<p>Thank you,</p>
<p>Blister<br>

The purpose of the database is to provide a robust list of reference points<br>
for hikers. If you are hiking and find yourself off-course, navigating to<br>
one of these points will get you back on trail.<br>
<br>
The description of every point includes mileage. For example, New Mexico<br>
waypoint 31_183WT means Segment 31, Mile 18.3, Water. That refers to a<br>
specific place where we found water, stopped for a moment, recorded<br>
additional data, photographed it, then moved on. We collected data for<br>
streams, intersections, road crossings, etc.<br>
<br>
We carried three gps receivers that collected data continuously at one<br>
second intervals as we proceeded. There are many places along the trail<br>
where there are no natural features to describe. Whenever we went more than<br>
7/10ths of a mile with no feature a Mileage point was created from the<br>
kinematic data. The Waypoint 32_025M is a Mileage point. (Segment 32, Mile<br>
2.5, Mileage) Think of the Mileage Waypoints as virtual cairns. They are<br>
based upon real measurements, are on the trail, can be navigated to, and are<br>
very useful even though there is no physical feature present.<br>
<br>
You will love those points when crossing such areas as the Bootheel where<br>
the trail is defined by cairns and wooden posts which are routinely<br>
destroyed by cattle.<br>

Using gpsbabel you can convert this to a .csv file (or whatever):<br>
<br>
gpsbabel -i garmin_gpi -f CDT.gpi -o csv -F cdtpoi.csv<br>
<br>
Many of the POI's just say 'Mileage' with no mileage, which is useful for a<br>
waypoint, but not a POI.<br>
<br>
Removing those, you have 3,329 POI's out of the 7,111 POI's, which is still<br>
considerable. Most of the 'stream' and 'creek' POI's don't have names, but<br>
still you can't complain.<br>

>>>> Jerry states:<br>
I have just put a POI file for the entire trail on the bearcreek website<br>
which you can download free of charge. Follow the Waypoints link to get the<br>
file. It contains the entire CDT waypoint list (over 7,000 points) Thereis<br>
a pdf file zipped up with the POI file. Read that and it will explain how<br>
to put the file in your Garmin.<br>
