MOBGIS
Map smarter — GIS guides, geospatial insights, and the mapping tools every analyst needs.
From converting coordinates and measuring great-circle distance to finding a bearing, working out map scale, switching area units, and judging GPS precision, MobGIS pairs free hands-on geospatial calculators with practical GIS guides and a richly illustrated museum of maps and cartography. Map smarter, analyse deeper.
GIS & Mapping Tools & Calculators
Free tools for every map — coordinate converter, distance calculator, bearing calculator, map scale calculator, area unit converter, and GPS precision calculator.
Coordinate Converter
Convert a latitude or longitude between decimal degrees and degrees/minutes/seconds — the notation switch every GIS import, survey note, and nautical chart demands
Distance Calculator
Get the great-circle (haversine) distance between two latitude/longitude points in kilometres, miles, and nautical miles — the geodesic measurement behind proximity analysis and routing
Bearing Calculator
Find the initial great-circle bearing from one point to another in degrees from true north, plus the 16-point compass direction — for navigation, aiming, and directional queries
Map Scale Calculator
Turn a distance measured on a map into the real ground distance using the map's representative fraction (e.g. 1:25,000) — results in centimetres, metres, and kilometres
Area Unit Converter
Convert land and area figures between square metres, hectares, acres, square kilometres, and square miles — normalise parcel and polygon areas from any source
GPS Precision Calculator
See how much ground distance each decimal place of a coordinate resolves to at the equator — store the right precision in your geodata without padding it with noise
Maps & Cartography Museum
Wander an immersive museum of the maps and instruments that shaped how we picture the world — landmark charts and antique atlases alongside the great map projections, the surveying and navigation instruments that measured the land, and the modern era of GIS, remote sensing, and satellite positioning, each in its own gallery, so you can get to know the story behind every map: how it was made, what it gets right and wrong, and how cartography grew into the geospatial science of today.
