  1. This not a Bench Mark. Its a landmark with horizontal position, Latitude & Longude, no elevation. A Bench Mark is a permanent object for which a elevation has been determined. If no elevation exists its considered a Horizontal Control Point.

  2. A point of interest maybe? On USGS Marks (only USGS), the letters stamped in the mark are the Survey Party Chief initials. So this mark was set by a crew supervised by JPH. Thats how they marked the BM's. USGS does not care about desiminating their data. NGS was the one that has plans to put it in the national database. That info was from our State Geodetic Advisor. But, it was going to be a large project that could take years. They have to request all funding thru Congress etc and these kinds of projects are not high priority for funding. He said the data for Michigan alone took up several file cabinets. Also most all of the USGS is on the old 1929 datum and will have to be shifted to match NAVD88.

  3. I have a new (never used) unit. Includes a 12" whip antenna, cable, wiring harness, and reference manual. Operates on a voltage range of 10-18 volts. Hookup to a Garmin handheld GPS requires a power/data cable which is included. Note-The power data cable may not work with all Garmin receivers? The Garmin number for the power cable is 010-10082-00 on the cable. It does not show up in the photo below. Size 1.5."H x 5.2"L x 3.6"W. This is ideal for Marine Use. $295+ $10 S&H in the USA, except Alaska & Hawaii which is More. Sorry I will not sell this outside of the US.

  4. Recoverey note means a report of someone searching for the mark and the condition it was found in, + any new information to help locate the mark in the furure. Everytime someone sends in a credible report it gets updated. Its the history of use etc. It speaks for itself. If you are just looking at datasheets on this site, you will find they are an abbreviated form of the complete document. LOCENGFIRM just means "local engineering firm" found or did not find the mark at that pariticular time. There are 1000's of codes in use describing various agencys, orgs, etc. When the person enters this code, the sybase program knows the tect to add to the database to agent the term "Recovery by Michgian Department of Transporation 2002 (MPR)" see example below The NGS Data SheetSee file dsdata.txt for more information about the datasheet.DATABASE = Sybase ,PROGRAM = datasheet, VERSION = 6.67 1 National Geodetic Survey, Retrieval Date = DECEMBER 7, 2002 SG0178 *********************************************************************** SG0178 DESIGNATION - BUMBLETOWN MIGS 1934 SG0178 PID - SG0178 SG0178 STATE/COUNTY- MI/HOUGHTON SG0178 USGS QUAD - AHMEEK (1980) SG0178 SG0178 *CURRENT SURVEY CONTROL SG0178 ___________________________________________________________________ SG0178* NAD 83(1994)- 47 16 48.14714(N) 088 25 41.44219(W) ADJUSTED SG0178* NAVD 88 - 377.

  5. Not all USGS Bench Marks are in the NGS database. The only USGS marks are those the NOAA, NOS, C&GS or NGS has used for their surveys. USGS is part of the Dept of the Interior and NGS the Dept of Commerce. fyi There are are over 100,000+ USGS Benchs Marks, Transcontinential Traverse (TT 40 S etc), Traverse and other mapping points that do not appear in the NGS database. That info has to come from USGS, they have no datebase that I know of. Whenever I needed any info, I had our record techs call USGS and they would dig thru the files and fax us the info. There means of reporting mark condition amount to writing a note on the record and thats it. USGS mark are archived by quadrangle name, so the lat and long, state and name of USGS map they are located in will get you the info. Go thur their web site but dut don't expect to get all the info you want, e.g. I want all the USGS marks for Nevada? Sorry if this is hard to read, its a copy of a copy of a copy etc and when I make it more readable, the file size is over 880kb. (only takes 1 sec on a cable model though) [This message was edited by elcamino on December 07, 2002 at 09:51 AM.]
  6. I can't read the stamping on the disk. The BM you found may have no relation to what is written on that Map. USGS Bench Marks are used for Mapping purposes mainly and they may not be any Lat and Long published for it? I know of no database for USGS marks. They were planning to incorporate in the NGS national database but the project was in need of funding, USGS records are all in manuscript format. It all has to be be manually entered and that would take a long time. Contact USGS with the location, e.g. GPS lat and Long, what stamped on the disk (not cast into) and they may send you information on that point.
  7. quote:Originally posted by FLMike:I don't understand their purpose. How and who determines where benchmarks are placed? What criteria are used for placement? Is it a location grid? I've been to the NGS website and didn't find it helpful. Infosponge, how ya doing there in Florida? Still taking good care of my geocaches down there? I notice you archived the Cha Cha. In simple terms a Bench Mark is a permanent point for which an elevation has been determined. Although a BM can have other data detrmined for it, e.g. latitude and longitude, its not a Bench Mark if no evelvation exists for it. Bench Mark = Veritcal Control Triangluation = Horizontal Contol Many Horz. control marks have vertical control and vice-versa. The org. that sets the marks have specifictions for establisment of the marks NGS has "Standards and Specifications for Vertical Control Surveys". That decribes the distance between marks, type of marks required for the various accuarcy of the Survey etc. Geodetic Bench Marks (Need Acrobat Reader to view this) Index of On-Line Publications [This message was edited by elcamino on December 06, 2002 at 03:28 PM.]
  8. Could be property markers? Sounds like the Surveyors initails and his license number.
  9. Right on, that's a PK (Parker-Kalon) masonary nail. You can buy them at most hardware stores. They come in various sizes. We used them alot in highway construction surveing but another brand is on the market called MAG nail. They are more magnetic than PK's.
  10. Here you go.. Geodetic Survey - Canada
  11. These marks are part of the public domain. Only cuations I would mention is; *Don't trepass *Don't report mark to NGS if you did not find it. I have found so many that the US Power Squadron for expample that were reported as not found but were in plain site. They were just confused by road changes etc. *Be carefull digging in areas where utilties may be present. You a responsible for any damage and that could run into a great deal of money if its telephone or gas. *Use extreme caution around major highways, many states require permits to work along the highways, mainly for safety reasons, yours and the travelling public. *Stay off of railroads! There are federal laws against RR trespass and they RR's take a dim view of trespassers especially since 9-11. enjoy the hunt..
  12. For history buff's, got to check out the old photo's and you thought your job was tough! NGS History
  13. I like this program a lot. You can easily ad text and position it anywhere in version 6.2. CompuPic
  14. If you want to see latest info try these NGS sites If you know the station name http://www.ngs.noaa.gov/cgi-bin/ds_desig.prl The PID http://www.ngs.noaa.gov/cgi-bin/ds_pid.prl Search an area http://www.ngs.noaa.gov/cgi-bin/ds_mm.prl I notice the db here is not up to date and you may save some time and energy checking with NGS
  15. Here's my 2 cents I was the senior Survey tech for 31.5 yrs. My equipment included 3 Leica GPS 500 receivers (the best), 1 base station and 2 RTK rovers, a 1999 4X4 Suburban and a 2001 Dodge 3/4 ton 4X4 ext cab pickup. I also had access to 6 other Leica receivers from other crews. We also have a network of CORS Stations MICHIGAN CORS all over the state, as well as NGS and Coast Gaurd CORS all over the Great Lakes. What we did was install our own survey markers (driven rods-Bernsten) or used NGS/USGS/USCE/NOS points that were clear to the sky. My boss (PS) had a goal of setting XY on all the NGS bench marks were could find and use. Would set the 3 receivers on the control points to base our survey on, no more than 2 miles apart and often only 1 mile. Run them for 5.5 hrs on 2 separate days, once in the AM and once in the PM. At the end of every day, the data was downloaded into a Dell Latitude and converted to RINEX data, then uploaded to NGS OPUS for final processing. We would then mean the sessions and do the field RTK work. Usually took a week to set the main control depending on the project size. Once the precise orbits were available we would once again run the OPUS doe the final time. Once we had the control points and while we were waiting for precise orbits (14 days latency), we would RTK (Real Time Kinematic) in our intermediate control, e.g. highway alignment points, plat corners, sections corners, mapping points. aerial control targets, etc. This usually involved driving along in the truck with the antenna out the window so as not to loss lock on the SV's. These points were tied for 2 seperate control points and averaged to predetermined specs. It took a minumun of 5 SV's to solve for position, x+y+Z+Time+Check. This was all done by the receiver, often in less than 1 second. You could learn to do this is 15 minutes, even the PS could do it. This data was then uploaded to the laptop, processed with Leica SKIPRO software. Any points that did not average, we would hit again the nect day. Once all the field work was done, we would reduce the state plane coords to a project datum for the consultants and constcution forces to use. This was often just a 1 man operation except for the summer, we used COOP students from MTU and Ferris to help out the crew. On one project last winter I ran 6 recievers at once using all NGS bench marks. I put on about 200 miles a day. Would set up the stations in the AM, program the receivers to turn on at noon and turn off a 5:30 pm. Area covered was about 20 miles and I just keep driving around checking on the equipment. It was along busy US-2. That was fun work (GPS) but living out of motels and working out of trucks for 31+ yrs got to me and I took early retirement in Nov. I was only 1 tech but had 3 professional surveyors to deal with, each one had a different view of how things had to be done. Image of our receivers set on a Order A station 2001 L 61 when we reobserved all the HARN in Michigan and postioned out CORS. It was not this point but I was sitting out in the boonies on a HARN point on 911 and just happened to turn on the truck radio at around 3pm.

  16. Yes, then can still exist. I worked for 31+ yrs for the Michigan DOT and reset a lot of marks myself (maybe 100?). Just this year we reset 4 marks because future highway construction will probably destroy the originals. Several years ago we reset 3 marks that were to be destoyed by a new highway but a change in plans put the road somewhere else, so the originals are still. I have also recovered NGS marks that were reset 30+ yrs ago and for whatever reason the original was still in place. I have on occasion found marks that other agencys said were not found, even NGS survey crews. USGS is the worst, they often employ summer help whod will report the mark as not found becuase they did not even look for it.
