About this app

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.

Ratings and reviews

Does not seem to work properly on a Galaxy A520 with android 8.0. When entering leveling backsight and foresight readings, for example, 1.651 the app changes the entry to 1.1.651 with an extra decimal point which it later cannot recognize as a real numerical value for any calculations. Also there doesn't seem to be a place to enter a BM starting elevation such as 272.458m so that the FS locations may be shown with a measured elevation as the leveling run continues to closure. I did not review any other functions in the app as I was only interested in the level book feature. Thanks but I will uninstall.

Seems like a great start, but the way the app exits when you enter a sub-function and then press the back button is really annoying. Also, I could not work out how to get anything to plot.

this is great, just what i've been looking for. I'm having trouble finding the directory on my phone where the *.csv files should go though.

What’s new

After hundreds of emails, this new version should work on the latest version of Android.
Its been quite a few years since I have done any coding and due to my lack of skills I've had to trim a few features that I could not get working again.
I ask anyone considering leaving negative feedback because the app dose not have your favorite feature or dose not work on your device to please remember that this is a 100% free app without advertising or any revenue streams whatsoever.
