Friday, March 24th, 2006

I have written a tutorial with step by step instructions about how I embedded my MG2 (v0.5.1) gallery into WordPress (v2.0.1).

GPX Viewer Update

Tuesday, March 21st, 2006

The GPX Viewer script now works in Firefox/Mozilla. With some minor changes to the data format and the script code I have been able to get the equivalent functionality working in Mozilla. Version 3 of the script is now available http://notions.okuda.ca/geotagging/projects-im-working-on/gpx-viewer/.

It also allows for the <html> tag to be with an <extensions> tag which is a more appropriate way to modify the format.

A special thanks goes to Alice Boit for the helpful comments about how I might be able to make it work in Firefox. I didn’t follow your advice exactly, but it got me off my ass to do something about it.

I bashed my head against the wall for a while trying to get the DOM code just right to allow it to work in IE and Firefox until I found this incredibly helpful page… http://www.quirksmode.org/dom/importxml.html.

The next step will be to define a real schema for my extensions.

Update to the MG2 Exif Parser

Monday, March 20th, 2006

Based on the comment by Catherine I decided to run some more tests on the Canon ISO data that I was extracting from the EXIF Makernotes. I confirmed that the script worked correctly for my S400 (and I assume other similar models).

Unfortunately, I discovered that it did not work correctly for files from my Rebel XT. The Rebel XT writes the ISO data to the “standard” location in the EXIF header.

I have updated the scripts to use the “ISOSpeedRatings” field if it is set and fallback on the makernotes if not. This seems to work correctly for photos from both of my cameras (here and here). This has not been tested with any other cameras.

Here is the zip with the changes

Google Maps GPX Viewer

Friday, March 10th, 2006

I have been working on this script for a while, and it isn’t really complete, but I have finally posted it publicly. This is a set of Javascript functions that can parse a GPX file (XML GPS data format) and view it using Google Maps. It shows track logs as a red line, waypoints as indicators with detailed information, and if a waypoint has an <html> tag, it will embed the html within the popup.

Take a look at the GPX Viewer Page

I will be posting the code with more details soon.

GeoTagging Photos

Friday, March 10th, 2006

I have just completed some pages describing GeoTagging of photos. I’ve given a basic description of what it means, why I do it, and where I think it is going to go. There are some projects that I have done and plan to do to help me visualize my photos using the GPS data and also help me tag them a bit differently to suite my needs.

GeoTagging Photos
What I Want from GeoTagging
How I use my GPS for GeoTagging Photos
GeoTagging Projects I’m Working On
Existing GeoTagging Technology
Selecting a GPS for GeoTagging

Let me know what you think or if there are other related projects you have seen, you are working on, or you think I should do.
