Suggest a utm crs

Source: R/utm_suggestion.R
suggest_utm.Rd

Uses calculate_utm_zone_crs to determine the UTM zone for each datapoint. Returns the most common zone in the dataset.

Usage

suggest_utm_zone_crs(lat, lon = NULL)

# S3 method for class 'sf'
suggest_utm_zone_crs(lat, lon = NULL)

# S3 method for class 'numeric'
suggest_utm_zone_crs(lat, lon = NULL)

Arguments

lat

vector of latitudes or an sf object

lon

vector of longitudes (empty in case x is an sf object)

Value

crs corresponding to the utm zone that the most data points fall into

Details

No weighting or averaging is done. Simply the zone that the most of points fall into. Arbitrary in case of a tie. Future versions may use a different (better) methodology to chose a zone when points fall into multiple zones.

Examples

suggest_utm_zone_crs(
  lat = c(47.6839952, 47.6839941, 47.6839939, 38.5382329, 38.5382306),
  lon = c(9.175119, 9.17498, 9.175254, -121.764227, -121.764351)
