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, ...)

Geodesist
The handy application for performingbasicgeodetic calculations.It provides coordinates in 6 systems:- WGS-84- PZ-90 (RU)- PZ-90.02 (RU)- PZ-90.11 (RU)- SK-42 (RU)- SK-95 (RU)- GSK-2011 (RU)In each of these systems the coordinates can be represented in3projections:- Geodetic (latitude, longitude, altitude)- Gauss-Kruger (6-degrees zones)- Geocentric (X, Y, Z)It allows you to perform the following tasks:- Direct and Inverse Geodetic Problem. Geodetic coordinatesaresolved on the reference ellipsoid. Gauss-Kruger coordinatesaresolved on the plane with or without the height.Geocentriccoordinates are solved in space.- Conversion of Gauss-Kruger coordinates into other zones.- Calculation of the azimuth and elevation of the Sun at anygiventime at any observation point (your own location canbeused).It allows you to receive:- Your own location data (coordinates, accuracy, source andtime,direction and speed)- Information about navigation satellites (PRN, azimuth,elevation,signal/noise ratio, etc.)It allows you to save the coordinates of points (marks) forlateruse in calculations. The coordinates of points can bespecified inany of systems and projections (after saving the point,itscoordinates are automatically available in all other systemsandprojections). Also the coordinates of your own location canbeused.It allows you to export marks from the application to externalfileand import marks from external file into the application. Therearetwo formats available for export/import: GPX and innerGeodesist'sone. In GPX the marks are exported/imported as"waypoints" ("wpt"tag).Exported marks are stored in the file with specified name inthefolder named "Geodesist" at the internal storage of thedevice.These files are available for other applications, such asfilemanager (i.e. they can be copied, deleted, sent viaBluetooth,etc.).Marks can be imported into the application from files located inthesame "Geodesist" folder.It allows you to visualize your data (marks, etc.) on the mapbasedon the "Google Map" service (the latest version of the GooglePlayservices must be installed on the device).It allows you to add new marks directly on the map.The application has an original customizable interface andprovidesthe variety of formats for input and display coordinates,angles,and other variables.The application has a built-in hints. To learn more about workingina particular tab open the tab which you are interested in andcallthe "Menu"(green button on the toolbar) -> "Hint".

This application generates InternationalSpaceStation (ISS) Transit Predictions for the Sun, MoonandPlanets.The user specifies a location, which includes latitude,longitudeand elevation. The application downloads the latestorbitalinformation (Two Line Elements or TLEs). The applicationgeneratesa transit prediction map which contains prediction pathsfor eachtransit within a specified alert radius.*** Please try the ad-supported ISS Transit Prediction Freebeforepurchasing to make sure you like the app ***USER INTERFACEThe main screen provides 4 buttons:•Location - Press this button to add or select thepredictiongeneration location•Two Line Elements (TLE) - Press this button to download TLEs•Generate Prediction - Press this button to start thepredictiongeneration•View Prediction - Press this button to view the prediction maportext fileThe options menu provides the following:•Locations - Press to add, select, edit or deletesavedlocations•Predictions - Press to view, share or delete savedpredictionmaps•Settings - Press to set user preferences•DEM Files - Press to list or delete the downloaded DEM Data•Help - Press to display this help page•About - Press to display application version, creditsandlinksLOCATIONSAdd a named observing location by clicking the "Add Location"buttonaccessible from the locations screen.The location coordinates can be entered in any ofthreemethods:•Manually - Enter latitude, longitude and elevation in thetextboxes. Positive values represent North and East, negativevaluesSouth and West. Elevation can be entered in meters or feetabovesea level depending on the current prediction units setting.As thecoordinates are typed, the map pans to the location.

Coordinate Master 3.7
BinaryEarth
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.
