Mytopo Gets Big Coverage Prior to NFC Championship Game

Mytopo.com is about to get the highest attention I’ve ever seen for a topo mapmaker. Their maps are to be used immediately prior to the NFC Championship game on Sunday between Philadelphia and Atlanta during CBS Coverage of the Subaru Primal Quest adventure race. You can download .pdf maps at the mytopo web site. They are the actual maps you buy. I have always said mytopo maps are the coolest of all mapping options given their waterproof quality and ability to combine quads to your specific needs. We have links to the Mytopo maps for highpoints on americasroof guide page. At topozone.com you always have the option to print mytopo maps.

Delaware First Adopter NAVD 88 For State Maps and Ebright Loses Foot!

The Colarado Springs Gazette reports that Delaware is the first state to adopt the use the new National Geodetic Vertical Datum of 1988 (NAVD 88) for its paper maps (as opposed to the 1929 Datum – NGVD 29 — used by virtually all maps).

Vertcon 2.1 To Convert NGVD 29 Heights to NAVD 88

In 1988 authorities discovered that gravity affected the measurements of heights (which had been based on 1929 principles). The results mean that big mountains such as the Rockies are as much as 6-7 feet higher (or more) and lower lying areas could actually be a foot or so shorter. The USGS has not fully adopted it because the cost would be billions to readjust all the maps. Plus the logarithm is complicated and does not fit into a traditional Excel style formula. The 1988 data is known as North American Vertical Datum of 1988. The 1929 data is known as the National Geodetic Vertical Datum of 1929.

VRML Cortonna Plug-In Browser (free)

There were high hopes for the Virtual Rendering Modeling Language (VRML) in the late 1990’s because it would permit web visitors to immerse themselves in a 3D World. However VRML never quite lived up to the billing as it is very high bandwidth (most of the world’s here are 500K or more) and the dispute between Microsoft and Sun over the Java technology effectively made the underlying technology difficult obtain or use.
