Localize After-the-Fact

[Jim Frame]

I cop to being particularly dense when it comes to localize procedures. Maybe it's because I don't use it often enough, or maybe I'm just getting too old to lock in new concepts, but this one still has me flummoxed despite the increasing detailed cheat sheets I've prepared.

Today's project is no different. Last week I surveyed a couple dozen points in NAD83 with the T-LS, which I subsequently adjusted and scaled/rotated (in Star*Net) to match the map I'm retracing. Now I want to stake some points on one of the parcel lines, so I set up a new page and created a new coordinate system using the house+ icon, and set WGS84(ITRF2008) as the underlying coordinate system. I then import the design points into that page. I go to the localize screen and populate the Design side with the design points. But when I click on the + icon on the Surveyed side, there are no surveyed points available to select.

Does localize only work the other way around (i.e., set up design points first, then survey the corresponding field points)? Or am I just doing something wrong (again!)?

 

[John Thompson]

Localize should work by adding design points first, then surveyed points. I'm not sure why there are no surveyed points to choose. I assume the new page with its new coordinate system are in the same job that you surveyed the point in. You should be able to add surveyed points to the localization by pressing the + icon on the Surveyed side, then Add Single Point, then Get from List, then click Survey at the top of the next page.

I wouldn't think you would want to set WGS84(ITRF2008) as the underlying coordinate system, but a projection instead, such as an LDP or State Plane. Unless the coordinates you got from Star*Net are in lat/long.

Give me a call if you like, and I'll try to get you going. (970) 466-0552

The Star*Net coordinates are in a local system (15000,15000), so a defined projection isn't available. WGS84(ITRF2008) is the default underlying system, so I didn't change it.

 

[John Thompson]

You should probably use whatever projection you used when you collected the surveyed points.
I wish the underlying coordinate system would default to the Project Coordinate System. It's almost always what I change it to, and I can't imagine a scenario where I would use WGS84(ITRF2008).
You will want to delete the imported points, change the underling coordinate system of the localization, re-import the points, and then use Localization to match up points.

The underlying coordinate system should be the surveyed coordinate system used.
