About Joseph

I live near Redmond, Washington, USA. In the past I have been a programmer for Boeing and also spent many years in the real estate field. A few years ago I was using off-the-shelf software to make jpg images that showed property boundaries on topographic maps. Then I realized I could write my own enhanced Google Map viewer and show property boundaries on detailed topographic maps. Then I modified a copy of my code so I could use it to share interactive maps in trip reports showing hikes/scrambles I did in the Washington State Cascades. That work has resulted in the Gmap4 you see today. Gmap4 uses the latest version 3 of the Google Maps API (Application Program Interface).

In addition to Gmap4, I am also developing software that will let you use a property legal description or good quality map to show the approximate property lines on Google maps. This will work anywhere in the world. In addition to giving you a map URL (just like Gmap4), this software will also let you download a GPX file with coordinates for the approximate property corners. The first version will be released in 2012.
