NOAA Datasheet (link) This is one of the higher quality confidence level marks. This monument is located along the side of a busy(ish) road, so make sure to remember to wear your PPE. Park in either the Holy Apostles Church (parking lot) or the Evergreen Orchard Farm (driveway), then walk along the south side of the road until you see the witness post. The benchmark is slightly below grade. Looking East (church lot in background) Monument Accuracy The Alpha RTK network co

NOAA Datasheet (link) This mark is close to my heart. It's one of the first I ever visited when I was planning the largest GNSS data collection project in New Jersey*. It is also of particularly high confidence level in both horizontal & vertical. Access is simple, park on Walnut Ave and walk to the median. The mark is in the concrete sidewalk. *Source: Me... It could have been the largest - it was 1,000,000 sub-inch points after all. It might even have been the large

NOAA Datasheet (link) This high quality monument is easy to find. You will park at "Jersey Freeze" (you should probably get the homemade ice cream too). Walk across into the grass median in the traffic circle along Rte. 33. There is a witness post next to the mark, which is slightly below grade. Looking East at Jersey Freeze Looking West Across Route 9 Monument Accuracy The Alpha RTK network consistently tests better than 1 centimeter horizontal and 2 cm vertical at this

NOAA Datasheet (link) This is a high quality monument that is super easy to find as well as access. You will want to park in the "Granite & Marble Shop" parking lot, right next to the giant billboard to the southeast of the shop. The monument is set in a cement block just at the top of the little hill between the billboard and the parking lot.

NOAA Datasheet (link) This monument located in Hackensack is set into a bridge foundation. Access is super-simple. Park your vehicle in Johnson Park, which is located a few hundred yards from the bridge along River Street. Then take the walking path up to the bridge and the monument is located just before the span begins. The street is busy but the sidewalk is sufficiently wide to safely occupy the spot with room for pedestrians to walk around you. Looking Toward Hackens

NOAA Datasheet (link) This marker is why I do this. Great accuracy, but fairly difficult to figure out a safe way to access. The monument is located atop the railway bridge abutment over the intersection of Camp Hill Rd & East Skippack Pike (Hwy 73). You access it by parking at the St. Thomas Preschool on Camp Hill Rd. Walk directly across Camp Hill Rd. onto the railway tracks, which are at grade here. Walk down the tracks toward the bridge. There are actually two brid

NOAA Datasheet (link) Disclaimer and **important** note. We included this monument: (1) Because it's a very funny example of government agencies not communicating (2) It's a perfect example of why Alpha RTK goes out and visits / verifies monuments! Now, despite the obvious problem here, this monument will be O.K. to use - after my calls / emails to PENN DOT are answered, and they move their new giant, stupid sign! Final note - because the marker is also under a tree, once

NOAA Datasheet (link) At 0.49 cm horizontal / 0.78 cm vertical (95% confidence level), this is one of the higher quality monuments within our service territory. The disk is located between the shoulder of the road and the winery. There is no witness post and the monument is about 6" BELOW GRADE. It would be a good idea to bring a metal detector for this one. No metal detector you say? No worries, if you are using our trustee ArcGIS Field Map, it will lead you directly o

NOAA Datasheet (link) This is a decent quality mark, however, the vertical is not as good as I would prefer (1.71 @ 95% confidence). Access is super-easy by parking in the Siesta Motel lot. The monument is located near the motel sign, slightly below grade, and has a dedicated witness post. Monument Location Accuracy The Alpha RTK network consistently tests better than 1 centimeter horizontal and 2 cm vertical at this station. Getting There KV2926 can be easily navigated to

NOAA Datasheet (link) Our first verification monument in Delaware! This one has terrific access via parking at the nearby Durkee Automotive repair shop, and walking to the grassy area. There is no witness post and the monument is BELOW GRADE. It would be a good idea to bring a metal detector for this one. No metal detector you say? No worries, if you are using our trustee ArcGIS Field Map, it will lead you directly over the disk via the handy Compass Tool. We really di
