Celestial
Explore daylight, darkness, twilight, moonrise, moonset, and moon phase data for a chosen location and selected time span. This theme is intended for practical planning where light conditions matter as much as weather.
Public Portal
Visbrunn Fieldcraft
Maps, weather, calculations, and AI-assisted analysis for planning, navigation, and field intelligence.
Coordinate conversions
Convert between LatLon, MGRS, Sexagesimal, UTM, Cartesian, ECEF, and Web Mercator in one place. This theme will make it possible to move from any supported coordinate type to all the others.
It is intended for practical field work, map handling, and reference lookups where the same location needs to be expressed in different coordinate systems.
Bearing and distance
Calculate the spherical distance and bearing between two coordinates, using inputs from any supported coordinate system. This theme is intended for practical navigation where true bearing, magnetic declination, and compass-adjusted bearing all matter.
It will also help estimate how far off target a route can end up when magnetic declination is ignored.
Map
Use Google Maps and Atlas of Canada / Toporama for coordinates, route pins, distance calculation, import and export, PDF output, and practical field planning.
