Cogo Surveying is a surveying application that includes: Points Database---> Import a .cogo points file or add points 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 send via email. Select your delimiter in the About Tab Plot Screen--> Display the points graphically from the point database. Zoom and pan the display. 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. 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---> Compute bearing and distance from a single fixed point to all points in the database. Traverse---> Calculate co-ordinates from bearing and distance of an occupied station. Bearings can be entered in DD.MMSS format or by using the separate fields. 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. This program can project a line through when lines don't intersect. Curve Calc---> Calculate the middle ordinate by knowing radius and chord length. Notes---> Change between a light and dark theme, also set the delimiter for import and export. FEEDBACK Please leave feed back about any bugs or requested improvements.
