Cogo Survey Pro is an app by Tom Blaxland in the Tools category. It includes native code only for x86 32-bit, ARM (legacy), ARM 32-bit and MIPS, so it won't run on 64-bit-only phones such as recent Pixels.
It asks for 2 permissions, 2 of them sensitive: read shared storage and modify shared storage.
What's new in v3.4
V3.4
*Fixed major crashing bug from v3.1.
*Re-added the option to use gradians as the angular unit. (default is DMS).
*Re-added a bearing calculator.
Description
From the listing uploaded by “split-store”.
Cogo Survey Pro is a surveying application that includes:
Points Database---> Import a .csv points file or add manually. Points form the database can be used in all the other modules by calling the point number with a comma in front of the point number.(ie ",pt105" in the easting field). Export to .csv and save to internal storage or sand via email.
Plot Screen--> Display the points graphically from the point database.
Area By Coordinates---> Calculate the area of a shape with up to 20 sides. Points are stored in a table that is editable.
2 & 3 Point Arcs---> Create arcs from 2 points and a radius or with 3 points. Then divide the curve in equal parts.
Bearing Conversions----> Convert bearings from decimal to DMS and DMS to decimal.
Bearing Calculator---> Add or subtract bearings in DegMinSec format
Survey---> Convert field data into XYZ coordinates. Input Hz bearing , vertical bearing and slope distance to convert to coordinates.
Inverse---> Compute bearing and distance between coordinates.
Inverse List---> Get a list of bearings and distances form a nominated point to all points in the database.
Traverse---> Calculate co-ordinates from bearing and distance of an occupied station.
Pt To Line---> Calculate the offset and chainage of a point from a line. Or Calculate coordinates by inputting chainage and offset.
Level Book---> A leveling sheet that allows the surveyor to input readings from a level run and compute elevations on the go.Export the data to a .csv file and send via Email. Never again get to the end of a loop without knowing if there has been a mistake made
Intersection By Points---> Calculate the coordinates of a point by intersecting lines with known coordinates. Can project a line through when lines don't intersect.
Curve Calc---> Calculate the middle ordinate by knowing radius and chord length.
Settings---> Choose a custon delimiter. Change between a light and dark theme. Change form degrees to gradians.
COMPATIBILITY
This app will not work on every single device and version of Android. There are hundreds of android devices and a wide variety of chip sets and testing them all is not possible.

Can I install this APK over the version I already have?
Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.
Is the Cogo Survey Pro APK safe?
No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. After downloading, check that the file's MD5 is f42534ed6a59bf60636e5d3b13ac4373.
