@jim-frame Yeah, I would rarely plan on a shot that long. I make it a point to tie between intervisible control stations when ever possible and somet...

@jim-frame I can get a half mile easy with the GMP101 and an MS60.

As Cameron pointed out, the main difference is pointing accuracy. The GRZ4 has an all-around accuracy of 5.0 mm and 2.0 mm at the yellow arrows while...

Oregon has 'Property Line Adjustments' and 'Boundary Line Agreements'. A PLA shits know lines and requires planning review and approval to ensure com...

@lurker Back when ArcInfo only ran on a mainframe or minicomputer, the term LIS (Land Information System) was thrown around quite a bit. The idea ...

A large number of my design clients request ALTA surveys when what the really want is a pre-design base map with boundary and record encumbrances show...

@lurker Geometric PPM not Atmospheric. They are input individually.

@mathteacher That is a different situation. The Determinant Coordinate System app does assume a projection, depending on the transformation techni...

@mathteacher I don't think Leica creates a coordinate system when none is specified. When no coordinate system is chosen, only local grid values a...

@bstrand While a rarity anymore, I do use the 'None' (no datum/projection) coordinate system when working in an assumed coordinate system utilizing...

They need 3770 more votes in the next 23 days for Lego to move the request forward. Everyone get out and vote.

My MS60 was over $1k including a full on service. But that is good for 2 years. The dealer's shop rate is well over $100 an hour.

@mightymoe In some cases, a centerline Mon in a median is the safest place to leave the instrument.

What???? Are you trying to say that centerline monuments don't have as much weight as right-of-way monuments? It is a rarity around here for the ori...
