Топогеодезия СК-42 MOD APK v1.2.4 [Paid for free / Free purchase] for Android

Calculations of field topography in full or abbreviated coordinates, in one or in adjacent zones.
Coordinates and heights in meters.
The angles of directions and places in thousandths of a scale are 60-00 or 64-00. In OGZ and PPZ angles are the same in degrees-minutes-seconds.
Maintaining a list of objects / points whose data can be used in tasks (250). Saving data to a file / reading / adding data from a file. The file in xml / txt can be edited / prepared in text editors.
 
Map (Google / ArcGIS / TopBox / Offlane Atlas) with point markers from the list (only with full coordinates).
Google map is cached for use without the Internet.
TopBox with an off-line manager in which you can download a visible area with selected zoom levels. The maximum volume of loaded tiles (tiles) cards 6000.
Atlases for offline use in the * format. mbtiles can be created in SAS Planet, MobAC. With the ability to dynamically change atlases. With the choice of the atlas folder (including on the SD card).

When you touch the map, the rectangular (in SK-42) and geodetic coordinates of the place are shown.
Coordinate grid (1 or 2 km) in SK-42. It is built around the first point on the list, 40x40 km.
Measuring distances on a map.
Starting the background GPS logger (points with a specified interval by the table and on the map).
 

  The composition of the tasks:
- direct geodetic task;
- inverse geodesic problem;
- recalculation of coordinates in an adjacent zone;
- serif conjugate observation;
- binding by a non-oriented range finder;
- snap by serif on measured angles;
- GPS data binding (geodesic and rectangular).
- the azimuth of the star at a given time. For the Sun, for the North Star;
- the nomenclature of the map sheet (specified scale for the given coordinates);
- notch with a stopwatch (taking into account air temperature), a stopwatch screen.
- GPS loggers (set the start / end time of the logger, period in seconds). As a result, points with coordinates and time in the list and on the map)

 Settings:
- thousandth scales (60-00, 64-00),
- Map service (Google, ArcGIS, Mapbox, Offline atlas)
- type of card for the selected card service,
- color style
- type of point markers on the map
- temperature (C / F)
- grid view
- saving data to a file / reading and adding data from a file.

The program is distributed "as is". Its use is the discretion and responsibility of the user.
