  1. Huh, I forgot I had started this thread! So, dev work on NGS-GPX v3 is no more - v2, while not perfect it does about everything that's needed. Instead, I've been focusing on a rewrite of Benchmap, to make the app more usable out in the field and add some features that the current version can't handle.
  2. Just happened upon NGS's site today, and saw this banner image: Other than the interest in the changes to the OPUS and all, the first thing that caught my eye was the map - thinking, "Okay, how many of those have I recovered in the past? I believe maybe three.." Sadly, the image is just for design and appearance, clicking on the link returns no info on the project highlighted there, darnit.
  3. Okay, yeah, I misread your comment to infer that YOU updated something, which really, really threw me for a loop. There have been some changes in years past in the Datasheet program on how it interprets log entries for stations, which likely helped these stations get an accurate monumented date. (I only know this because one such update that was made back about a year ago) caused a whole bunch of logs that had no status, no agency, and no date appear tacked onto the history list on the datasheet. Had to talk to them and point out some stations that were causing this.
  4. My favorite chiseled marks are: https://www.geocaching.com/mark/details.aspx?PID=EE0017 because of the location, history, and the fun way to get there, and https://www.geocaching.com/mark/details.aspx?PID=EE0061 Because it is so easy and plain to see, and old.
  5. Interesting - I personally love the chisled items - squares,circles, triangles. Heck - there's a really neat one up in Wyoming west of Cheyenne - at the Ames Monument. I did a quick search of this mark in @op's post in the NGS database from August, and it was not tied into the NGS database, so you won't be able to log it here on GC.com; and if it's not on Waymarking, you may need to create a new waypoint there.
  6. Ah, awesome. Some newer Android phone chipsets are starting to allow dual-band readings as well, though I am not sure about their accuracy. I am looking into it for some additional features to my Android app, but honestly? I'm a hardware guy, and love having the hardware at my disposal.
  7. Wait, did the receivers cost $250, or the parts FOR the receivers cost $250?
  8. You're getting into satellite positioning and other stuff - those satellites know exactly where they are, at all times. You want things stuck on the earth - but, the tectonic plates are shifting, moving. So even if everything was 'fixed' on earth here, they woldn't actually be 'fixed'. BTW, Dave - I thought you were retired! What the hell you doin', man? As far as static markers still being used - that's a huge positive there. I just had to flag for a survey crew along our tracks - 20 miles of ROW being surveyed for elevation and ditch grading. Readings every 30 feet. Every morning they would set up on a nearby NGS level mark, run to the railroad and back, verify the measurements, then take off heading down the tracks. I learned a lot getting to watch them do, what I call, the "other side" of benchmarking: Finding a station, using it for a baseline elevation, then reading offset readings every x feet.
  9. When you have a code that is one of the "Destroyed" codes (X, Y, or Z), you can go here: https://geodesy.noaa.gov/cgi-bin/ds_pid.prl Put in the PID, and select "Include Destroyed Marks". Then you will get the full datasheet as it was before it was marked destroyed.
  10. PG0585 is coming back as "Surface Mark Reported Destroyed", and the two entries listed in the datasheet show it's been gone for a while: PG0858 STATION DESCRIPTION PG0858 PG0858'DESCRIBED BY COAST AND GEODETIC SURVEY 1935 PG0858'IN BURLINGTON. PG0858'AT BURLINGTON, CHITTENDEN COUNTY, ON THE UNIVERSITY OF VERMONT CAMPUS, PG0858'ABOUT 62 YARDS SOUTHEAST OF THE SOUTHEAST CORNER OF THE FLEMING PG0858'MUSEUM, ABOUT 65 FEET NORTH OF THE CENTER LINE OF A CINDER ROAD PG0858'LEADING TO THE DORMITORIES, AND 38 FEET SOUTHEAST OF A POLE. A BLOCK PG0858'OF GRANITE PROJECTING ABOUT 6 INCHES ABOVE GROUND. PG0858 PG0858 STATION RECOVERY (1964) PG0858 PG0858'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1964 PG0858'SURFACE MARK REPORTED DESTROYED. Interesting statement on the Philo datasheet: PG1937'MOUNT PHILO IS A 1-INCH BOLT THAT PROJECTS ABOUT 4 INCHES PG1937'AND IS LOCATED DIRECTLY UNDER A SMALL WHITE BUILDING (CARETAKERS PG1937'TOOL SHED). Directly under? Really? :)
  11. Good luck! Let us know the outcome!
  12. This. Specifically, ngs.infocenter@... will be the people you need to talk to.
  13. As stated in other areas of this forum, n a very small percentage of USGS marks are in the NGS database. (GC here has a copy of the NGS database.) So, you can waymark it, or kist save your pictures for a cool find. :)
  14. Thanks guys - That helps, but I'm the type that still needs to watch and help. (What you old me is like telling me the coordinates of a station, while I need the directions and how-to-reach. :D)
  15. Frankly, I would love to learn the process and equipment needed to run a level check. Every time I come by a vertical monument that I THINK is disturbed, or is questionable, I wish I had the knowledge and know-how to check and verify.
  16. Honestly? Don't touch it. Don't try to push it down. Frankly, you don't know how FAR you should push it down. If the rod has been shifted due to any reason, the station is no longer valid, and pushing it back wouldn't suddenly 'made' it valid any more.
  17. I would actually be surprised if you haven't.. I mean, it is obviously the less-used term: Heh. Otherwise, I'm not sure how accurate of an order it would be if the marker swam around all year!
  18. I would like to get the hardware necessary to do this at some point, honestly. Just to learn.
  19. BenchMap will soon had a data option to ONLY show these GPSonBM stations that are needing recovery.
  20. When I was running the above numbers, I noticed something strange, and found out I had a bug in my database. I fixed it, and reimported all the stations, and found something interesting: Of all the publishable stations, 10 have a "MONUMENTED" or "FIRST OBSERVED" (code of "S" in the NGS database) by the "GEOCAC" agency. ONE is legit, DM5588, actually named 'GEOCAC', the special one set back in 2009. The rest are odd ones: All have an entry similar to:
  21. Interesting - decided to run some queries on my database (which is from the begiinning of September of this year) - There are 256 stations that were monumented by GSC, and total of 366 that they've reported on. There are 155 in AK, 2 in ID, 37 in ME, 10 in MI, 9 in MN, 15 in MT, 34 in ND, 3 in NH, 21 in NY, 11 in VT, and 9 in WA. 205 datasheets do not have a 'Mark Logo' entered in. 9 are marked as CGS, 33 are marked as GSC, and 19 are marked as NGS.
  22. The capped ones (rods with access covers) will certainly be picked up by a metal detector - those are aluminum access covers, and they'll be picked up. (At least, with a real metal detector. Since they ARE aluminum, it's possible cheaper, iron-only or magnetic-only detectors won't pick them up..!) Some stations will list the ownership of the land the mark sits on Usually if it is along a roadway, but is outisde the right-of-way, I will do searches in someone's yard - but never do any digging or metal-detecting without contacting the owners. And yes, more than a couple times I've walked up to the front door. In the case of a few times, the owner even knew where they were, and pointed me to them. Now, about looking for Found/Not Found stations, in areas I am not familiar with or new to - like Bozeman in this case, I will usually stick to previously Found marks. But in areas I know well (like around where I life, or have lived, or will be in a long period of time for work or vacation), THEN I will pull up Not Found stations, and spend some extra time looking for them. The more familiar you are with the area, the more it helps looking for more difficult marks.
  23. Apologies I fell silent, all - starting Wednesday, the contractor stepped up their game, and the rest of the week was too busy for me to get out. Which really bums me, because I had some others I did want to get. Unlike many others here (like Kayakbird here), I don't have a set criteria. I usually start by looking on Google Earth for stations - things I like to see are either stations along old roadways/ole rail beds, or stations with interesting features. Some things I take into account is: 1. whether it HAS been recovered before or not (and how recently. For trips to parts of the country I don't normally go, I stay away from not found marks, because of time. 2. If it's along a roadway, how active/busy the road is. (i.e. two-lane vs 4-lane divided highway) - too much traffic, too much like work. 3. If it's along a railway, whether the line is still active or not (or if I have permission or not - a couple of the ones I found last Tuesday I had legal access to the railroad's ROW.) 4. any other intersting features. (i.e. Near an old school building, the 1936 description lists an 'old road', Again, I usually start on Google Earth with Topo maps, and go from there.
