【實用教育app】USAtlas Geology|最夯免費app-綠色工廠好玩App

US GEOLOGY is one of the twelve chapters of The National Atlas of the United States® which was coordinated and lead by USGS, this is the effort of more than 20 Federal agencies. The other layers are, Agriculture, Biology, Boundaries, Climate, Environment, Government, History, Map Reference, People, Transportation and Water. Geobyte is planning to produce these Chapters in future.In this volume we have incorporated 46 layers of vector information available at The National Atlas of the United States® Website. These include Earthquakes, Volcanoes, Geologic Map, Mineral Operation, Magnetic Field, Waterways, County Boundaries and many more.Detailed Geologic Maps (scale of 1:500,000 or larger) and Faults, from Open-File Reports of USGS of 48 States are also included.The Legend or Key for each layer has been designed in the way that one can select all or select specific units from the legend and generate the map of particular interest. For example you can generate map with only Cretaceous Sedimentary rocks and only earthquakes of certain magnitude. The units on the map can be identified by long tap on the map.With the GPS capability of the system the location on the ground is known and you can add, edit and save notes on the map.The distance between two points and the area of polygon can also be calculated.All the layers can be displayed in both Mercator and Lambert Equal-Area Projections.There is no need to have access to WIFI, 3G or 4G Data Network to use this app. All the data are saved in your device.The National Atlas of the United States®, is the registered trademark of the United States Department of the InteriorThe layers included are:Coal FieldsContinental DivideEarthquakeElevation ContoursGeologic MapGeologic Map – CalderasGeologic Map – FaultsGeologic Map – Impact SitesGeologic Map – Metamorphic AreasGeologic Map – 1:500 k State by StateGeologic Map – Faults 1:500 kGlacial LimitsKarst – Engineering AspectsKarst – SubsidenceLandslide – Incidence and SusceptibilityLandslide – Costly EventsLandslide – Costly Regional EventsMagnetic Field - Declination, 1 degree incrementsMagnetic Field - Declination Secular Variation, arc mins/yrMagnetic Field – Horizontal Intensity, 500 nanoTesla incrementsMagnetic Field – Horizontal Intensity Secular Variation, nano Tesla/yr Magnetic Filed – Inclination, 1 degree incrementsMagnetic Field – Inclination Secular Variation, arc mins/yrMagnetic Field – Total Field Intensity, 500 nanoTesla IncrementsMagnetic Field – Total Field Intensity Secular variation, nano Tesla/yrMagnetic Field – Vertical Intensity, 500 nanoTesla IncrementsMagnetic Field – Vertical Intensity Secular Variation, nanoTesla/yrMineral Operations – Agricultural MineralsMineral Operations – Construction MineralsMineral Operations – Ferrous MinesMineral Operations – Ferrous Processing PlantsMineral Operations – Miscellaneous Industrial OperationsMineral Operations – Nonferrous MinesMineral Operations – Nonferrous Processing PlantsMineral Operations – Refractory, Abrasive and Other Industrial OperationsMineral Operation – Sand and Gravel OperationsMineral Operations – Stone, CrushedQuaternary FaultsSeismic Hazard – Peak AccelerationSurficial Deposits (Eastern & Central States)VolcanoesWaterwaysState BoundariesCounty BoundariesRailroadsMain Roads (inc Ferries)Latitude and Longitude…………………………..
