Coordinate Master 3.7
This powerful geodesy app allows you toconvertcoordinates between many of the world's coordinate systems,computegeoid offsets, and estimate the current or historicmagnetic fieldfor any location. It also includes surveying toolsto compute thepoint scale factor and grid convergence.The app uses the PROJ4 library and a lookup filecontainingprojection and datum parameters to support over 1700coordinatesystems. Lat/lon, UTM, US State Plane, and many, manyothers aresupported. You can also create your own coordinatesystems if youknow the parameters.The app also supports affinetransformations toallow you to set up local grid systems.Seehttp://www.binaryearth.net/Miscellaneous/affine.htmlfordetails.The app either takes manual coordinate input or uses yourcurrentGPS location. The computed location can be displayed inGoogle Mapsvia your web browser with a single button press. It alsosupportsMGRS grid references.You can export any lat/lon, UTM or transverse Mercatorcoordinatesystems to a HandyGPS datum (.hgd) file for use as acustom datumin HandyGPS.The magnetic field calculator page computes the Earth's currentorhistorical magnetic field at a given location. Themagneticdeclination computed is useful for compass navigation sinceitrepresents the difference between true north and magneticnorth.Field inclination and total intensity are also computed. Thistooluses the International Geomagnetic Reference Field model(IGRF-12).See http://www.ngdc.noaa.gov/IAGA/vmod/igrf.html for fulldetails.Years from 1900 through to 2020 are supported.The app can also compute the geoid height offset for agivenlocation, using the EGM96 model. Geoid offset can besubtractedfrom the height reported by GPS to give your actualheight abovesea level.Online help for the app is availableathttp://www.binaryearth.net/CoordinateMasterHelpNOTE: A version of this app is now also available foriPhones.Permissions required: (1) GPS - to determine your location, (2)SDcard access - to read and write user projections file.
CartoDruid - GIS offline tool 0.60.16
CartoDruid is a GIS application developed by InstitutoTecnológicoAgrario de Castilla y León (ITACyL) thought as a tool tosupportthe fieldwork aiming to solve the problem of disconnectededitingof georeferenced information. In many field areas, mobilecoverageis insufficient to work in a reliable way. CartoDruidprovides asolution to this problem allowing the visualization onraster andvectorial layers stored on the device and allowing thecreation ofnew geometries (entities), drawing them directly on thescreen orusing embeded or external GPS. CartoDruid doesn't requierepreviousGIS (Geographic Information Systems) knowledge and it'seasy toconfigure and use. This allows any person to use it tomanagefieldwork information and then export generated data to usethem inexternal applications. What can CartoDruid do?: - VisualizeonlineGoogle Maps. - Use vectorial cartography loaded on aSpatiaLitedatabase. - USe rasterimaginery loaded on a RasterLitedatabase. -Consume online WMS services. - Create new layers on thedevice. -Configure filtering on vectorial layers to determinevisiblegeometries based on their attributes. - Configuresymbologies andlabels based on SQL expressions (easily). -Configure searches onlayers using SQL queries. - Configureidentification forms based onSQL queries. - Edit the attributes ofa geometry. - Manually drawgeometries: points, lines and polygons.- Draw and edit geometriesbased on GPS data. - Edit geometriesusing several useful tools:split using polyline, circular split,merge geometries, multipartexplosion. Graphically move existingvertices of geometries. -Create new geometries intersecting layers.- Automatically savegeorreferenced data: creating and update datesand others. -Associate pictures to entities. - SIGPAC search basedon existingdownloaded data. - Length and area measurement tools,defining themeasurement units. - Guided and line based navigationto help theuser reach her destination. - Manage bookmarks. - Importvectorialdata using CSV files. - Import SpatiaLite databases. -Exportseveral formats: SQLite, KML and CSV. - TOC (Table ofContents)management: sorting, symbologies, hierarchical sorting(folders). -Works with SHP (ESRI ShapeFile) as an exprimentalfeature. -Controlling the operations that can be performed on alayer viaconfiguration (overlaps. move vertices. deleteentities,identification and edition, ...)

QField for QGIS - EXPERIMENTAL 1.9.3
QField focuses on efficiently getting GISfieldwork done.The mobile GIS app from OPENGIS.ch combines a minimal designwithsophisticated technology to get data from the field to theofficein a comfortable and easy way.QField unleashes the full power of the QGIS styling engine tobringyour customized maps to the field, collect attributes forfeatureswith configured edit widgets like value lists, checkboxes,freetext or pictures taken with the device camera.QField is an open source project, the documentation, muchmoreinformation, the source code and possibilities to to supporttheproject can be found at qfield.org (preferred) or by buyingtheQField for QGIS Karma editionapp(http://qfield.opengis.ch/karma).QField is built from ground up to be touch oriented and easy touseoutside.It is based on a few paradigms● GPS centric● QGIS desktop compatible● Fully working when offline● Synchronization capabilities● Project preparation on desktop● Few and large buttons● Mode based work (Display, Digitizing,Measuring,Inspection,...)QField is built using Qt5, QtQuick 2 (both are supportedandsuggested by Qt) and OpenGL so it is future proof and itspearheadsQGIS towards Qt5.OPENGIS.ch is happy to help you with the implementation ofmissingfeatures.
