In iemisc: Irucka Embry's Miscellaneous Functions

Conversion of Engineering Survey Measurements to Decimal Degrees (KY and TN)

Description

Takes Kentucky or Tennessee-based Northing and Easting engineering survey measurements [based in the State Plane Coordinate System (SPCS)] in meters, international foot, or US survey foot and converts those values into geodetic coordinates of the World Geodetic System (WGS) (19)84 (EPSG:4326). [MapTiler Reference] Each latitude [Y] and longitude [X] point is verified to be located within Kentucky or Tennessee.

Usage

engr_survey(
  Northing,
  Easting,
  units = c("survey_ft", "foot", "meters"),
  location = c("KY", "TN"),
  output = c("basic", "table"),
  utm = c(0, 1)
)

Arguments

Northing	numeric vector (or character vector with numbers, commas, and decimal points) that contains the Northing engineering survey measurement in meters, international foot, or US survey foot
Easting	numeric vector (or character vector with numbers, commas, and decimal points) that contains the Easting engineering survey measurement in meters, international foot, or US survey foot
units	character vector that contains the system of units (options are survey_ft (United States Customary System) [US survey foot], foot, or meters (International System of Units) [meters])
location	character vector that contains the location name ('KY' for Kentucky or 'TN' for Tennessee)
output	character vector that contains basic for the default result using a simple data.table or table for the result as a complex data.table
utm	numeric vector that contains 0 or 1 only. 0 represents do not provide the utm coordinates and 1 is to provide the utm coordinates

Value

the projected associated latitude [Y] and longitude [X] coordinates in Decimal Degrees as a data.table or as an enhanced data.table with the latitude [Y] and longitude [X] coordinates in Decimal Degrees, Degrees Minutes, Degrees Minutes Seconds & the State Plane Northing and Easting coodinates in meters, US survey foot, and the international foot

Note

Please Note: If you have Kentucky North/South Zone survey measurements, then please use the Kentucky Geological Survey, University of Kentucky - Kentucky Single Coordinate Conversion Tool (http://kgs.uky.edu/kgsweb/CoordConversionTool.asp) instead. That tool will give you the geographic coordinates too. This R function, engr_survey will only be valid for NAD83 / Kentucky Single Zone.
