EarthMeter
Read full descriptionHide full description
With EarthMeter you can calculate distances or areas and their circumferences with an arbitrary number of positions. EarthMeter uses algorithms that take the earth's curvature into account; therefore also far from one another measurement points also lead to correct results. Additionally, EarthMeter is able to calculate and visualize the course between two arbitrary points on earth. All these calculations are based on a user chosen geodetic datum. As measurement units metrical and imperial linear and surface measure units are availble. Another topic that is covered by EarthMeter is the conversion of position coordinates of one coordinate system into another one. For doing so different geodetic datums and projection methods can be chosen from the user. The user has the choice between all commonly used geodetic datums and projections. EarthMeter supports likewise iPods, iPhones and iPads.
Topography
This tool helps civil engineers, architects, and surveyors measure surface areas and convert coordinates. It allows users to calculate polygon areas, convert coordinates to UTM EGSA87 Datum, and export measurements in DXF, KML, or TXT formats via email.
- Convert coordinates to UTM EGSA87 Datum
- Calculate polygon area in square meters
- Export measurements in DXF format
- Export measurements in KML format
- Export measurements in TXT format
- Input coordinates manually

The application is very useful to Civil Engineers, Architects, Surveyors, and those interested in measuring a surface area or converting its coordinates to UTM EGSA87. This tool enables users to: 1. Convert the coordinates (x,y) to UTM EGSA87 Datum 2. Calculate the area of a polygon in square meters (m2) 3. Send the above measurements by e-mail in [dxf] file format. The dxf file can be opened in a MAC or a PC by any drawing application like Autocad. 4. Send measurements by e-mail in [kml] file format. The kml file can be opened in a MAC or a PC or iPhone by GoogleEarth application. 5. Send measurements by e-mail in [TXT] file format. The text file contains coordinates either in EGSA87 Datum or Latitude and Longitude in decimal degrees or UTM coordinates. The measurements mentioned above can be provided not only by placing the iPhone in each border of a surface area, but also from distance (when users are on their bed or their sofa). Users may also have their final measurements by entering the coordinates either in EGSA87 Datum or Latitude and Longitude in decimal degrees.

Verdict
The clearest difference is update cadence: Topography at every 2 months against EarthMeter's every 10 months. EarthMeter's advantage is price ($0.99 vs $3.99) and iOS requirement (13.0 vs 16.1). On ads, in-app purchases and device support there is nothing between them.
