Tips for Success

  • ✓First row must contain headers
  • ✓No empty rows in data
  • ✓Use consistent number of decimal places
  • ✓Bearings in format: DDD°MM'SS" or decimal degrees
  • ✓Elevations in meters
  • ✓UTF-8 encoding preferred

Common Errors

"Cannot detect survey type"

Check your headers match one of the supported formats

"Invalid bearing format"

Use DDD°MM'SS" or decimal degrees (e.g., 82.25)

"Point already exists"

Enable "Overwrite existing points" or rename duplicate points
