**Circles:** (radius in meters needs to be on the same line, for example: N 60° 18.814 E 025° 01.125 [160.9])

**spitko's GeoCircles instructions**

The purpose of this page is to provide easy to use interface for plotting
a big number of circles and calculate intersections to Google Maps.
The text copied to the input windows
will be processed line by line and if a coordinate and [radius] is found, it will be
added to the map. The **Detection results** will display details for
each of the detected coordinates.

Coordinates can be entered in various formats. Examples are available at GeoCalc page.

If no coordinates and [radius] are found, the line will be skipped. Duplicate coordinates and [radius] are skipped as well.

**Note!:** Google Maps has relatively large error when displaying big circles (radius >10 km).
Intersections are calculated as accurate as possible. Use GeoCalc or some other calculator to verify intersection distance to the circle centers.

**MAP** button will open Google Maps engine with detected circles and calculated intersections.

**GPX** button will start download of the intersection points using same order as calculated by the service. This GPX file can be uploaded to your GPSr device for the field use. May the force be with you.

Alternative way to use this page is to provide the coordinates in the URL in
decimal degrees notation, separated with a colon:

gc.pitko.net/map/circles.pl?c=60.314500,25.021500,250:60.315300,25.016800,160.9&i=60.316321,25.018858:60.313867,25.017160

But then you have to calculate the intersections elsewhere..

This is part of Mysteerinmurskain toolkit ;)
