Changes

In the geological field, maps generated from data researchers had collected which then would be portrayed onto a basic map, which in general gives information about Earth’s reliefs interpretation, and then described on a flat plane, called geological map. Geological maps give informations about geological conditions on particular area which includes rocks units and its structures. From geological map, we can obtain type of rocks, thickness, lithological bearings ([[strike]] and [[dip]]s), faults, folds, [[fracture]]s, or many processes have had occurred in earlier times.

[[W:William_Smith_(geologist) | William Smith (1769)]], a British engineer known as a pioneer of stratigraphy, created a very useful geology maps and illustrated the distribution of rocks on a topographic map.

[[w:Luigi Ferdinando Marsili | Luigi Ferdinando Marsigli (1658-1730)]] created topographic maps for military use of the visited countries (Italy, France, Germany, the Balkans, and Turkey). Marsigli published a mining district map in Hungary and sketched the distribution of sulfur near his hometown, Bologna (1717). Probably, the first geological map drawn by an anonymous naval cartographer in 1757 where in the Heligoland islands he added boundaries of four different types of rocks.<ref>Franceschelli, C. &Marabini, S. 2006: Luigi Ferdinando Marsili (1658-1730): A Pioneer In Geomorphological And Archaeological Surveying.
