The blue line is our GPS track, the purple are the trails (provided by LocalMotion.com).

It was a bit damp and cloudy, but the trails weren’t too muddy the woods were beautiful. A fine time was had by all (especially Hudson, the pooch).

For those who are interested in the extent of the development, I’ve biked the new roads and recorded their positions via GPS:

Middle Road KML

To accomplish this task, I have written a new script, the KML Joiner that will combine any KML documents on the web together into a single (referenced) KML document. (try it out)

More Detail: for those interested in KML
The resulting document is a collection of network links, each of which points to one of the KML URLs specified. Doing this rather than combining their text together into a static KML document prevents style collisions as well as allows changes in the source data to propagate to the combined document.

Refresh intervals can optionally be specified for every source document allowing for a server-friendly combination of static data with rapidly changing data. By default, no refresh interval is specified, making the linked documents load only once when first accessed.

Example:

View the KML Joiner with fields filled in that generates the map below.

The map above is of the trip mentioned in a previous blog post, but this time the data sources (1. a static KML file with the path and house placemark, 2. a dynamic KML document generated with my Photo set to KML script) joined together with the KML Joiner script instead of manually put together with a text editor.

Usage:
You are welcome to use this script hosted on my site, or you can download it and run it on your own computer/webserver.

Please post any suggestions for fixes or changes. Thanks!

The map above was generated with a GPS track of our path (the blue line) and the photo output from my new photosetToKML.php script

To fill this niche, I present a small script I wrote to generate a KML file from the geotagged photos in a set:

Features:

• Generate a KML file from a Flickr photo set
• Directly open the KML file in Google Maps
• Choose what size image to include in the placemark description for each photo.
• Optionaly draw a path (line) from photo to photo ordered in one of several ways: by date taken, by date uploaded, by set order. Useful for making a quick and dirty map of a trip.

Examples:

• KML / GoogleMaps – Some photos from Cape Cod.

• KML / GoogleMaps – A set of photos from a trip I took around Turkey, with lines drawn chronologically. Since this is a large set that causes GoogleMaps to time-out, I’ve downloaded the KML file and then re-uploaded it to my website. This is the method I recommend for large photo sets.

You are welcome to use this script hosted on my site, or you can download it and run it on your own computer/webserver. If you would like to run it yourself, please be aware of the following…

System Requirements:

• PHP 5.2 or greater.
• The PEAR Flickr API

This script is available under the GNU General Public License (GPL) version 3 or later. (Source Code)

Updates::

• 2011-10-06
  • Moved the source-code to Github
• 2007-08-27
  • Now uses htmlspecialchars() to clean titles instead of htmlentities(), the latter of which was causing excessive translation of German characters. Thanks Stefan Geens, for pointing this out.
  • Form now generates valid XHTML 1.0 strict.
  • Now can use image thumbnails instead of camera icons. Thanks for the idea Nicolas Hoizey.
• 2007-08-24
  • Now escapes ampersands in titles and descriptions. Thanks Jesse for pointing this out.

  Future Improvement Ideas::

  • Add an option for icon size.
  • Add options for custom icon/path styles. I’m not sure whether to give several options, or just provide a field for a block of arbitrary KML style-markup.

  This weekend I started a project of mapping hiking and biking trails around Vermont and building a Google Earth data set of the trails, their heads, and destinations.

  View the trails in Google Maps.

  To view the trails in Google Earth:
  

  1. Download and install Google Earth
  2. Click on this link to open the Vermont Hiking 'Network Link' in Google Earth
  3. The 'Network Link' will automatically refresh with new data once a day.

  If you are hiking/biking with a GPS unit and would like to contribute to this project, please send any trail submissions that you have mapped to:
  Adam Franco
  afrancoATmiddleburyDOTedu

  In your submission, please include:
  – Markers at:
  — trailheads
  — parking
  — trail-junctions
  — overlooks/destinations
  – A path of the trail (GPS tracklog perferred overguess

  Note: While estimates based on looking for points in Google Earth (rather than marked via GPS) are welcome, please add “(unverified)” to such waypoint/path titles.
