After seeing all of the great photos from the PMBA party at Tom's, and having people repeatedly ask "Where was that?", I thought the following video might be interesting.  It shows how you can take your photos in Picasa (a free photo manager from Google) and "tag" them with the location where they were shot using Google Earth.   If you upload them to Picasa Web Albums (another freebie - it's how the Trail Maintenance albums are published to the web) the location of the picture is shown on a Google Map on the album page.  You can also create a .KMZ file containing the pictures and locations, which you can email or post to a website.  The .KMZ file will allow viewers to see the pictures on a Google Earth image in the locations were they were taken.  Pretty neat...

That is cool Jon. I was recently e-mailed a .KMZ file and was the first time I had seen that in which Google Earth opened upon execution of the file and the picture was linked to the location. We should try this to see how it looks.

You can try it with a file from here: http://www.pearcefamily.org/Wiss%20VG%20quadrant%20tour.kmz  I took some shots from Wiss and geocoded them into a KMZ file.  I just looked at it and some of the pictures aren't showing up, but some of them are OK and you can see how it works.

Jon,

I want to do something very similar to that but take a GPS map from a ride around the wiss and get a map overlay, then import that in to flash and create an interactive map of as many points on the route as possible.  It wouldn't be terribly difficult, a little time consuming but it would be really neat when it was done.  This is sort of what I was talking about, but its not quite as complete as it is missing the trail route and the pics look like their just hovering in the woods (although if you zoom enough you can see a light outline of the trail from the cameras that took the satellite imagery).

http://www.mtbguru.com/  Is pretty cool for those with a garmin 305/205/etc....

I see you have a few postings Jon.  Cool.   I have a Garmin, but normally don't take ride pictures, so I haven't posted anything yet.

We can add the trail track to a GE picture file so the lines from the pictures end up on the trail, not at spots in the park as they do on my example.  Those tracks came from my older GPS (Garmin 201), which often lost the satellites in the woods as evidenced by the straight lines that would show up on the tracks.  The new one (Delorme PN20) is more sensitive and I've programmed it to record track points every 10 feet or so.  Having ridden over previously-recorded tracks, I can see that it's pretty consistent. 

Anyway - I'll try to get out with a camera and the PN20 when it gets warmer and take some good shots that can be geotagged and placed onto a track.  I already have pretty good maps (I recently added the Lincoln Drive trail), but the pictures will be an interesting addition.

Jon, can you give me a heads up on the Lincoln Drive trail?  Where is it?  Is it on the other side of Lincoln?  Where does it start and end?  Thanks

I've only ridden it twice - once in the dark - so I may be off a little with directions.  It's across Lincoln Drive from the rest of the park, but generally parallels Lincoln Drive.  Starting from Ridge Ave on the Wiss side, ride east until you pass under the overpass - then turn left and head into the woods.  The trail is pretty easy to follow, although there are some variations that others took, but I didn't get lost.  You'll hit a steep downhill behind the 92nd District police station - continue across the street and keep going in that direction.  You'll wind up near Wissahickon Ave where it interects Lincoln.

to get to the other end, from the end of Forbidden Drive, at Lincoln Drive, you ride along the paved path like you are about to ride the other side. Instead of going up the hill to the left you go right and along this side of LD following a thin pavement. It ends at a cross point say 100yds up and you cross LD there. Head up that road a bit and the path in is on your right.

Along the trial you have to cross another road and the hill to carry on the trail is extremely steep. You might think it's not the right way but it is.

It's an unkempt and little used trail which means its both exciting and unpredictable.

I've drawn a path for it HERE from the end of Forbidden Drive. Be sure to click on the Aerial View and zoom in and move around to check it out.

Nice job Kelly.  I appreciate.  I think we met a while back at the Fairmont Classic bike race at Belmont Plateau.  I broke down and could not finish.  Does anyone know what happened to that race?

Great map layout Kelly, couldn't have explained it in words better than that map. There are not too many trails out there that you have to cross a sketchy section of Lincoln drive. My favorite way to enter is that  second trial entrance or the right side, after you cross Lincoln drive. It starts with that steep climb that hovers next to the edge thats like a canyon. Its fun to ride from North to South.

I actually rode it that weekend starting from the parking lot at the movie theater in main street in Manayunk heading towards Saylor Park.  It's a great little technical trail.  Thanks for the heads up.  As I made it to the the police station, I had a nice over the bars incident due to traffic on that public road that you cross.  So if any rides it for the first time, BEWARE, flying past the police station might get you run over.
