Google Earth Discoveries

Today was hard to keep track of things, internal GPS went haywire thanks to Google Earth and the slew of data it is helping to generate. First there was the discovery of Ogle Earth, a blog dedicated to GE by Stefan Geens that shares tons of great material.

From there I jumped to TrackerGE and NMEA2KML, tools still in beta that generates .kml files from GPS signals that can be displayed by Google Earth as a moving map. These are some among other efforts along the same lines.

Also rediscovered the redesigned website of GPSVisualizer by Adam Shneider which now can help generate .kml files used by Google Earth plus a web interface to GpsBabel tools.

Then after running into a version of Opera Mini for the i870 Motorola phone I got distracted trying to get it to work on the i415 which kept failing for lack of memory.

Navizon & GeoTags

Finally I was able to get back to my original track and talk about the latest version of Navizon which brings location-based comments as we've seen with HereCast. Version 1.3 adds a new tag to the PocketPC app through which comments can be made to create a tag associated to a geographic location or GeoTag.

You will need to uninstall the previous version before installing the new one which will also include SQLCE 2.0. You can create tags at the location (after obtaining a GPS fix or location information from WiFi) or at your own account page at Navizon's website. But I couldn't see tags from other people last I tried. You can control the radius around which tags alerts should popup and how often a search for new tags should be made.

The issue I see here, which is the same brought up by GISUser on his blog is that we need to start talking about Open Data. Shared structured data with a common interface for use by different client & server apps. Navizon can be a client, as PlaceLab and A2B. already carries the best wireless database available, GeoUrl 2.0 comes back and is picking up speed fast with location data. "WikiTags" or similar effort to keep a single (replicable database) of comments, stories, reviews, notes about particular geographic locations plus photos. A common travel diary shared among all of us.

[Update] But the folks from Navizon seen to be on top of their game about this too.

This should answer your concerns about open data:
