+rogbarn Posted March 2, 2005 Share Posted March 2, 2005 holograph has started a neat new website called Extreme Benchmark Hunting. He also started a thread called Extreme Benchmarking in the regular Benchmark Hunting forum to talk about it. His method of listing the extremes by various catagories in each state is one of the main methods that I have of identifying possible errors in the NGS database. This is why several people have started waving their hands to identify problems in his list. Most of the time, the problems are in the database. Use the opportunity to research the problems and then send it in to the NGS, making sure you include the PID, the designation and a careful description of the problem, including any research that you did and possible explanations that might help them find the problem. For example, I found a group of 5 stations that had obviously incorrect elevations. I estimated their elevation from topozone. Playing with the numbers a bit, it became obvious that the elevations were recorded in feet but entered in meters. Problem and solution in one package. I've started this thread to allow specific problems to be listed so we don't step on each others toes. Although the research isn't necessary, having the PID and a brief description of the problem will help all of us know what problems have been identified. Plus, I'll be able to add it to my list of errors identified by geocaching and reported to the NGS. Quote Link to comment
2oldfarts (the rockhounders) Posted March 2, 2005 Share Posted March 2, 2005 Rog, here's one for you. JM0276 It is listed as being in San Juan County, Utah, but the description says it is over 2 miles east of the state line (that would be in Colorado). I did not submit it. John Quote Link to comment
reidster Posted March 3, 2005 Share Posted March 3, 2005 Here's another: PID SG0166 It's height is listed as one meter, but it's a stone monument on the shore of Lake Superior?!? I also did not submit it. reid. Quote Link to comment
Z15 Posted March 3, 2005 Share Posted March 3, 2005 (edited) Did you find SG0166? I was in the area and its all private land. Heavily wooded area as well as much shore erosion. Mean Lake Superior water level is 602 ft Edited March 3, 2005 by elcamino Quote Link to comment
reidster Posted March 3, 2005 Share Posted March 3, 2005 (edited) Did you find SG0166? Nope, spent too much time hanging out at the Gay Bar. Thanks for asking, reid (troll from brighton) Edited March 3, 2005 by reidster Quote Link to comment
+BuckBrooke Posted March 6, 2005 Share Posted March 6, 2005 Looking at Arizona, it's oldest and oldest least recovered PID is DA0048, K 319. The PID's monumentation date is in error, because the stamping on the mark is listed as 1952, in the datasheet. Also, the monumenting description sounds modern, not mid 1800s. I've reported this to Cheryl. Quote Link to comment
MarkDuster Posted March 16, 2005 Share Posted March 16, 2005 NY0942 Listed as the northern most in California is actualy in Klamath County Oregon about 4 1/2 miles north of the CA-OR state line. Quote Link to comment
mapjunkie Posted July 4, 2005 Share Posted July 4, 2005 NO0268, reported on the datasheet as 12203 FT. The highest point in the state, reported by Netstate, is 5474 FT. The metric height is consistent with the elevation in feet 3 miles away at the Hyannis airport. I'll take this one to NGS. - Matt Quote Link to comment
