spitko's Geo::Ellipsoid calculator instructions

The purpose of this geo calculator is to provide easy to use interface for often needed calculations. The interface has been designed to be usable on the field with mobile browsers and small displays.

Input fields

Following input fields are available:

• PosN - Position
  Calculator tries to guess the location from the input. All of the following inputs are converted to the same position:
  
  N 60° 18.814 E 025° 01.125 (copy coordinates from the cache description)
  N60' 18.814 E25' 01.125

  Check the results to verify that the calculator understood your input. As you can see from the examples, this calculator assumes Northern latitude and Eastern longitude. Other three corners of the world are handled as well:
  
  S33' 51.411 E151' 12.906
  -23.015309 -43.310104
  40' 41.351 -74' 02.673
• DisN - Distance
  Distance from the position in meters.
• DirN - Direction
  Direction from the position in degrees. Also known as true bearing.
• DWIM
  Do What I Mean. Send input fields to the calculator for processing.
• Clear all
  Clear all input fields. Almost self-explanatory.

Conversions and Calculations

Following tasks are done if there are enough inputs available:

• Convert and display coordinates (PosN)
• Calculate projection (Pos1 + Dis1 + Dir1)
• Calculate distance and direction (PosN + PosN)
• Calculate direction intersection point (Pos1 + Dir1 + Pos2 + Dir2).
  
• Calculate two distance intersection points (Pos1 + Dis1 + Pos2 + Dis2).
  
• Display difference to 3rd position and its distance to support manual decision between the two intersections (Pos3 + Dis3)
• Add links to GeoPlot and GeoCircles (distance intersections) or Ympyröijä (direction intersections) for mapping the results
