I don’t know if you are trying to mark out a fence between two of your points, or if you want to mark out a fence in relation to the property line like surveyors do.
If you want to mark out a fence in relation to the boundary, you need to know that in the United States, parcel data is most often given in a coordinate system based on NAD83, using the so-called State Plane Coordinate System (SPCS), which is divided into zones and is not the NAD83(2011) system.
Arizona utilizes a State Plane Coordinate System (SPCS) with three zones: West, Central, and East. The system uses easting (X) and northing (Y) coordinates to represent locations within these zones.
Your town is located in the central zone.
The boundary points of the parcels are measured in the following way:
- GNSS measurement with position in NAD83(2011) EPSG:6318, i.e. 3D system (exactly EPSG:6318 is NAD83(2011) without hight),
- transformation (projection) from NAD83(2011) to SPCS for the specific zone in which your town is located, in your case to NAD83 / Arizona Central (ft) EPSG:2223, i.e. 2D system.
Some GPS receiver software has the ability to automatically transform measurement results from a 3D system to a 2D system, in this case from NAD83(2011) to NAD83/Arizona Central(ft) and during the measurement you can compare the result with the coordinates and distances on the map in NAD83/Arizona Central(ft).
I don’t have such software and I use the very popular QGIS program, where I can draw points and lines. Additionally, QGIS has the Proj program with which you can transform coordinates. The QGIS program is free, but it has some bugs. Proj can also be downloaded from the Internet.
For example, if you take a measurement and get a point in NAD83(2011) (RTK result is in NAD83(2011) if the coordinates of the base reference station are in NAD83(2011)), you can convert its coordinates to NAD83/Arizona Central(ft):
echo “-111.95 34.05” | cs2cs EPSG:6318 EPSG:2223
It seems like a lot of work, but once I do it I’m happy.
Do not transform to WGS84, because these transformations have very low accuracy of around 2m or worse.
