I’ve tried out a little mobile phone application called “Phone 2 Google Earth” The program communicates with a bluetooth GPS and records your position at regular intervals for as long as required. You can also record placemarks. The data is saved as a KML file, which can be transferred from the phone to a PC. Here is an example google earth file .

The llamas featured as a placemark can be seen on my moblog.

The colour and opacity of the track can be modified once it has been imported to Google Earth via the advanced tab. It would be nice if there was an option to output the data as a GPX file which would preserve other aspects of the GPS log, such as speed and altitude, giving you the choice as to whether to use Google Earth or GPS Visualizer to view the data. As a basic tracking program however, Phone2GEarth works very well, and I’ll use it for fieldwork.

Having acquired my new phone (Nokia 6630) and a cheap Bluetooth GPS from EBay. I’ve finally been able to test 3dtracking.net
It all works just as advertised on the web site. Simply install a small application on your mobile, turn on a Bluetooth GPS and walk around. Your location is transmitted by the mobile to the 3dtracking server which draws your track live on a Google Map or in Google Earth.

A practical fieldwork application still eludes me, but I’m working on it!

This excellent little script is working again. Go to FlickrFly site.

Simply add a tiny snippet of code to a description of a geotagged photo in Flickr, and on clicking the newly created link, you fly to that location in Google Earth.

Here is an example of a photograph tagged with Flickr Fly Click “Fly to this location” to see the effect. You need Google Earth installed obviously!

I’m rapidly talking myself into getting a smartphone. Not just for the live GPS tracking (see previous post), but because of concepts like Semapedia. In essence, Semapedia is about tagging real world locations with internet-based information, via a mobile phone. This could be a great (and highly subversive) fieldwork activity. Ogle Earth has posted an interesting article about Semapedia, together with a link to a Google Earth file for viewing some of the recently tagged locations.

I’ve printed out my first Semapedia tags – can you guess where they are going?

update 29/1/06 – I’ve just addded my first Semipedia tagged image to Flickr. The image is also tagged with the Flickr Fly script – see this page for more details

Sand dune transect using Magnalox

I spent part of today on Braunton Burrows investigating whether a hand-held GPS can take the place of compass, clinometer ranging poles, tape measure and general fieldwork tedium.

I have concluded that the wonderful Magnalox does indeed offer a challenge to the traditional fieldwork method for dune transecting.

There is an option to view the dune transect on a Google Map or in Google Earth. The thumbail is a screenshot of the Magnalox web page.

Thanks to Tom for helping with the fieldwork!

Magnalox is a web-based application that brings a GPS track to life. Simply download and save your track from a GPS and upload it to Magnalox (“magnificent GPS logs and interactive reports”) The application will transform your track into an animated map that reproduces your journey. Elevation data is displayed as an accompanying graph, and the “killer feature” is the option to add notes and pictures from the journey into the finished log. This is a fantastic way to record field trips. I have produced a short magnalog of my local block with photographs. You can also view the magnalog on Google Earth or on a Google Map.
