au’s Toshiba W54T is a cellphone with GPS, and a BREW application that can get location data and save to disk is preinstalled. I took this data to show the path on Google Maps.
Here is how:
Application name is “地図ビューアー”. Click on “簡易ハンディGPS” and location data will be displayed. Click on “アプリ設定” , then select “あしあと設定” then use menu “あしあと保存” to save GPS data taken up to that point. The data is like this:
本ファイルは、地図ビューアーにより出力されたGPS情報ファイルです。 出力日時:2008/02/28 11:49:51 +0900 +++GPSログ+++ 888234473,130.682362,33.660194 888234490,130.682271,33.659990 888234502,130.682474,33.659684 888234510,130.682458,33.659749 888234522,130.682501,33.659808 888234529,130.682389,33.659781 888234540,130.682265,33.659781 888234552,130.682120,33.659845 888234560,130.681890,33.660124 888234572,130.681890,33.660027 888234580,130.681745,33.660027 888234592,130.681804,33.659968
In order to display this as path on Google Maps, this data needs to be converted to KML. GPSBabel, which also has Mac binary, is said to be able to do this. But, it always failed to convert the above formatted file for unknown reasons. When the above file is opened from GPSBabel, it is recognized as “DeLorme XMap/SAHH 2006 Native .TXT” but GPSBabel tried to read the first item as latitude not timestamp. Websites mentioned that the above format is “NMEA 0183 sentences”, so I tried converting it to KML and conversion finished, but resulting file does not contain any coordinate. Finally I manually converted it to KML by putting the latitudes and longitudes in between as follows:
ff0000ff 5 #myStyle 130.682362,33.660194 130.682271,33.659990 130.682474,33.659684 130.682458,33.659749 130.682501,33.659808 130.682389,33.659781 130.682265,33.659781 130.682120,33.659845 130.681890,33.660124 130.681890,33.660027 130.681745,33.660027 130.681804,33.659968
This KML file can be opened from Google Earth for viewing, or put somewhere and feed the URL to Google Maps, e.g., as follows:
http://maps.google.co.jp/maps?q=http://bp.maltech.jp/gpstest/2008_0228_134831.kml

My usual working time at the office is about 8:30 to 20:30, and when desk work takes much of this time, and often I continued at home, my back hurts. Walking is the best cure, and here is my route back home to get the car (walking back home at night is too cold…) from GPS data taken by my cellular phone (au W54T):
