Geodetic Benchmark F171

Besides waymarking and geocaches, there is another fun little GPS adventure known as benchmark hunting. These are actual metal (usually brass) disks that are permenantly embedded into buildings, cement posts, sidewalks and other structures.

These “geodetic” benchmark disks are cataloged and maintained by the National Geodetic Survey (NGS), a federal agency within the U.S. Department of Commerce. They are used by land surveyors, builders and engineers, map makers, and other professionals who need an accurate point of reference to where they are at that moment. These “benchmarks” can be found through out the United States.

This one here is labeled as F171 and was first embedded in 1934.

First Waymarking Test

Welcome to Cybernaut Explorer!

This is a first test for uploading a Geotagged photo and creating a WordPress entry all from the iPhone.

The goal of this particular blog is to post interesting photos with geotagged GPS data to allow people to visit the place in the photo using only said data in their own GPS units. Once you visit the location, log into this blog and post a comment that you have found the location (or in cases of a Geocache, post what object you found in the cache.)

Basically, it’s like a treasure hunt game using technology; hence the title of this blog, Cybernaut Explorer!
