Calculate latitude of an object given the distance and angle to a reference point

Calculate the latitude of an object marked in an image processing software. For example, use the Arrow Tool in imageJ, leaving from a reference point (the camera with GPS) to the object.

doNewLatitude(
  distance_vertical,
  latitude_reference,
  masl = 0.01708348,
  km = FALSE
)

Arguments

distance_vertical

numeric. Vertical distance of the object to the reference (GPS camera). This can be the output of doCalcDistanceY()
latitude_reference

numeric. latitude in decimal degrees of the reference object.
masl

numeric. meters above sea level of the reference object.
km

logical. Is the distances be in kilometers (km=TRUE) or meters (km=FALSE)

Value

longitude of the object
