engr_survey_reverse | R Documentation |
Takes geodetic coordinates of the World Geodetic System (WGS) (19)84 (EPSG:4326) [MapTiler Reference] and converts those values into 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. Each latitude [Y] and longitude [X] point is verified to be located within Kentucky or Tennessee.
engr_survey_reverse(
latitude,
longitude,
units = c("survey_ft", "foot", "meters"),
location = c("KY", "TN"),
output = c("basic", "table"),
utm = c(0, 1)
)
latitude |
numeric vector [or character vector with spaces, degree symbol, single quotation mark, and/or escaped quotation mark (\")] that contains the latitude coordinate point. The following possibilities are valid: -25.02, "25\U00B056'50.2068\"N"; "15\U00B056'58.7068"; "37'1'54.3'N"; "35 8 46.44496", "35'8'46.44496". If the North designation is not provided, then it will be added. The latitude/longitude coordinate pair has to be either a numeric or character vector (no mixing). |
longitude |
numeric vector [or character vector with spaces, degree symbol, single quotation mark, and/or escaped quotation mark (\")] that contains the latitude coordinate point. The following possibilities are valid: 09.83, "25\U00B056'50.2068\"W"; "15\U00B056'58.7068"; "37'1'54.3'E"; "35 8 46.44496", "35'8'46.44496". If the West designation is not provided, then it will be added. The latitude/longitude coordinate pair has to be either a numeric or character vector (no mixing). |
units |
character vector that contains the system of units (options are
|
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 |
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 |
the geodetic coordinates as projected SPCS Northing and Easting
coordinates as a data.table
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_reverse
will only be valid for NAD83 / Kentucky Single Zone.
