Tutorials, guides, and articles about coordinate systems and geospatial tools.
Everything you need to know about GeoJSON - the universal format for geographic data. Learn the structure, geometry types, and how to work with GeoJSON effectively.
Learn how to convert coordinates between Earth-Centered Earth-Fixed (ECEF) and Earth-Centered Inertial (ECI) reference frames. Understand the role of Earth's rotation and sidereal time.
Learn about inertial coordinate systems and why they're essential for satellite tracking, space navigation, and orbital mechanics. Explore ECI, ICRF, and other inertial reference frames.
Dive into the world of satellite tracking. Learn how Two-Line Elements work, what SGP4 propagation does, and how to predict where satellites will be.
Learn how to convert coordinates between WGS84 (latitude/longitude) and UTM (Universal Transverse Mercator). Understand zone selection, conversion formulas, and common pitfalls.
Learn the fundamentals of geographic coordinate systems, from WGS84 to UTM zones, and when to use each one for your mapping projects.
Learn the crucial differences between geographic coordinate systems (latitude/longitude) and projected coordinate systems (meters/feet). Discover when to use each and how projections transform our round Earth onto flat maps.
A beginner-friendly introduction to coordinate systems. Learn what they are, why we need them, and how they form the basis of all mapping and location-based applications.
