# Description

The Geodetics Calculator is designed to solve the first ("direct") and second ("inverse") geodetic problems with an accuracy of 1e-6 meters over a range of 27 different reference ellipsoids and spheriods.

Background:

The first ("direct") geodetic problem is defined in the following manner: given a point (in terms of latitude and longitude) and a direction ("azimuth") and distance from that point to a second point, determine the location (in terms of latitude and longitude) of the second point.

The second ("inverse") problem is defined in the following manner: given two points (in terms of latitude and longitude), determine the direction ("azimuth") and length of a line (in our case, both a geodesic curve (a great circle) and a rhumb line) that connects them.

Usage:

*To solve the first ("direct") geodetic problem, simply enter the origin point, fill direction and azimuth fields and press the Calculate button.

*To solve the second ("inverse") geodetic problem, simply enter the origin and destination points and press the Calculate button.

*In order to change the units in which the input or output fields are given, simply choose a different measurment unit and press the Calculate button.

Terminology:

*Geoid Altitude output field rtepresents the height of the local geoid (EGM96 = Earth Gravity Model 1996) above mean sea level at the origin and destination.

*Forward output field represents the azimuth from origin point to destination point.

*Backward output field represents the azimuth from destination point to origin point.

*Direct output field represents the length of a straight line ("geodesic curve" / "great circle") connecting the origin and destination point, along the reference ellipsoid.

*Rhumb output field represents the length of a rhumb line connecting the origin point to the destination point, along the "meridional earth spheroid model" (radius of 6367.445[km]).

*Latitude and Longitude output fields represent the location of the point located at a given azimuth and distance from the origin point (they are given in degrees with a decimal notation).

Notes:

*Origin and Destination points location can be entered in two different notations:

> degrees decimal notation: choosing "decimal" would require the location input field to be entered in degrees in decimal notation, eg.: 32.156845 or -4.563542.

> degrees/minutes/seconds notation: choosing "d/m/s" would require the location input field to be entered in degrees/minutes/seconds notation, eg.: 32 50 6 or -14 29 50. notice that a space should be enter between the degrees, minutes and seconds.

*Longitude is given in the boundary of [-180.0, 180.0] degrees. Negative longitude represents the western hemisphere and positive longitude represents the eastern hemisphere.

*Latitude is given in the boundary of [-90.0, 90.0] degrees. Negative latitude represents the southern hemisphere and positive latitude represents the northern hemisphere.

*If the origin and destination points are the same, than the distance between them would be zero, and the azimuth between them would be NaN ("not a number").

*If the distance entered by the user is such that the reference ellipsoid would be encircled, than the calculator would take it into consideration.

*Output fields are labeled using indent font, to seperate them from input fiields.

*Geoid altitude is calculated using a bilinear interpolation performed upon a 0.25 degrees grid of point value in a "tide-free" system. The Geoid is given relative ot the WGS84 ellipsoid. Maximum error in Geoid altitude is one meter.

*Rhumb line distance is calculated using earth spheroid radius of 6367435[km]. Deviation from other calculators might originate from the usage of a different earth radius.

## CoordTransform

CoordTransform is an Android tool useful for coordinates conversion between Geodetic system (latitude & longitude as provided by GPS ) and Universal Transverse Mercator (UTM) geographic coordinate system.

Currently only supports 58 reference ellipsoids datums, but is not capable of transforming coordinates from one ellipsoid to another. Default ellipsoid is WGS84 used by GPS system.

Supports 3 different latitude / longitude input formats: decimal degrees (DD.DDD), degrees /decimal minutes (DD MM.MMM) and degrees/minutes and decimal seconds (DD MM SS.SSS). The UTM input format are those: Northing, Easting, Zone and Hemisphere.

This app allows you to work in UTM or latitude / longitude coordinates so you can use it with topographic maps. It's an useful tool for map reading and navigation (land or sea navigation). So is useful for outdoors sports like hiking, orienteering, bushwalking, mountain biking, kayaking, surveying or anything where you need to read coordinates from a map and convert coordinates between formats. Also useful in Search and Rescue (SAR) or GIS where conversion between different formats is needed.

Also you can enter coordinates dynamically using a map. Drag and drop the marker around the map and coordinates (both geographic and UTM) will be updated.

Coordinates can be copied to clipboard with long press or shared via SMS or e-mail.

## Surveyor Tools Free

'Surveyor Tools Free' uses your device's sensors to give you positional information about your surroundings. It is very similar to a theodolite, but it offers additional features.

It provides GPS location and altitude, as well as elevation angle, horizon tilt angle, and azimuth angle.

'Surveyor Tools Free' includes three screens: the main screen and two different compass screens. One is a simple compass that is like a traditional compass with a moving needle. The other compass is more modern and displays a number of useful datums. These include azimuth angle with bearing and magnetic field strength, as well as the magnetic field data accuracy.

'Surveyor Tools Free' displays the following information on the main screen:

-GPS latitude and longitude,

-GPS (corrected - see below) altitude,

-accuracy of the altitude,

-artificial horizon,

-elevation angle,

-azimuth angle and bearing,

-horizon tilt angle,

-location of Sun, Moon, and Sun's shadow displayed on the screen with appropriate symbols,

-current local time, weekday, and date,

-vertical and horizontal 'crosshairs' centered on the field center,

-calibration button,

-picture button to take and save a picture of the current view,

-direction type (magnetic or astronomical),

-sliding 'drawer' menu.

All the angles displayed on the screen are in degrees units. The artificial horizon is shown as a bright green line. It tilts and moves vertically to compensate for camera rotations.

The 'CAL' button on the main screen is the calibration button. If you have not yet calibrated 'Surveyor Tools Free', the button will appear green. To calibrate 'Surveyor Tools Free' first select the object you want to calibrate with on the settings screen (Moon, Sun, Sun's shadow). Be careful when pointing at the Sun; use the Sun to calibrate only when it is cloudy and you can still see the Sun through the clouds.

Next, point the camera at the object and make sure it is centered on the gray cross in the center of the screen. Then press the 'CAL' button. The button will change color to yellow, indicating you have calibrated the 'Surveyor Tools Free'. The calibration will be remembered when you close the app. You can calibrate again as often as you wish. Only the most recent calibration is used.

Once you have calibrated the 'Surveyor Tools Free', the 'Direction type' will change from 'magnetic' to 'astronomical'. Prior to calibration the compasses give magnetic directions; after calibration they give astronomical (or true) directions.

The calibration performed by the 'CAL' button corrects for the difference between directions to the magnetic and true north as well as offsets between the center of the display and the measured azimuth and elevation angle values.

When the GPS coordinates cannot be determined, 'Surveyor Tools Free' uses the last saved coordinates to perform the calculations to display the Sun, Moon, and Sun's shadow.

The reported altitude is corrected to the EGM96 geoid. This provides absolute accuracy in altitude just under one meter. Location data are automatically saved when the app is exited.

A 'settings' screen provides options to choose the altitude units (meters or feet) and the object for calibration.

When you take a picture of the current view, the image is named according to the date and time according to the following format: 'yyMMddHHmmss.png'. The location of the file is briefly shown when it is saved. You might experience a 2 or 3 second delay between the time the picture is taken and when it is saved. You can access the saved files by connecting your Android device to a computer via a USB cable.

Applications of 'Surveyor Tools Free' include geocaching, hiking, prospecting, emergencies, accident reports, real estate, surveying, observational astronomy, and archaeology.

This app is ad supported.

Correct up to geometric altitude of 84 kilometers.

Correct up to geometric altitude of 84 kilometers.

Usage:

1) Enter mean sea level characteristics (temperature, pressure).

2) Enter chosen altitude (geometric or geopotential) or gravity, press 'done' and view atmospheric properties at

chosen altitude \ gravity.

3) Enter chosen airspeed (true or calibrated or equivalent; up to the local value of the speed of sound) or dynamic

pressure or mach number (up to mach one), press 'done' and view airspeed type converted at current altitude and

mean sea level characteristics.

Notice:

1) Long click each variable label to get information regarding that variable.

2) Use right side spinners to change input / output unit types.

Remarks:

1) Airspeed conversion is performed under assumption that air is compressible, isentropic (subsonic; mach

number < 1.0) and dry with a constant specific heat ratio.

2) If at current atmospheric conditions, input airspeed results in mach number greater then 1 - calculation is

performed according to mach number 1.

3) Density is calculated using a perfect gas relationship.

4) Geopotential altitude input is defined according to standard day (ISA).

5) The mean molecular weight is not corrected for geometric altitude above 80km.
