geoTools is a set of tools to use in geologic, geophysical, engineering and geographic work. It includes the estimation of important geophysical quantities, such as Bouguer anomaly, topography, magnetic declination, and so on, and a quick coordinate converter. The ideal companion for a geologist, a geophysicist, an engineer, a geographer, and to any person interested in the Earth Sciences. The easiest and more effective way to calculate the parameters associated to the Earth's gravity field and magnetic field. Convert coordinates from geographic to Universal Transverse Mercator and vice-versa with one touch, using different reference systems. Since 2018 the app uses the new IGRF geomagnetic model to estimate the magnetic parameters. All the tests we've made show very good results. PLEASE NOTICE: geoTools is free, no ads, no purchases, absolutely free! If you use it, please let a review to help us keep upgrading the app. It is simple, fast, and very important to us!
