My name is Barry Graham - I am a new member of CartoTalk.
I was member of the Australian Institute of Cartographers from 1957 until 2002.
I taught Civil Engineering/Surveying at Moorabbin technical college in Victoria, Australia from 1978 until my retirement.
To keep my mind active in retirement I have written FreeCOGO - a program for the graphical solution of plane Co-ordinate Geometry computations in Surveying and Civil Engineering - specifically for students in Victoria but it may prove useful elsewhere.
The program is free for student and non-commercial use and may be copied and distributed without charge according to the licence agreement.
I am willing to provide an unrestricted licence to any organization that offers feedback and suggestions.
NOTE: The program uses bearings as azimuths in whole-circle format clockwise from north.
Traverse misclose and adjustment
Intersection of lines, arcs and bearings
Location of points on arcs and lines
Creation of lines and arcs as entities
Calculation of running chainage from entities
Create chained entities offset from existing entities
Measurement of areas within closed figures
Area seek by moving a point on line, on arc or parallel boundary
Data enquiries on points, lines and arcs
Elevation by gradient, points and interpolation
Import/Export XYZ data reduced from field files
Create a DXF file annotated with bearings and distances
Generate data reports of point coords, lines , arcs and layers
Generate data setouts from occupied points
Data organised in layers
Display options to select/display layers, points, elevations and entities
Routines to translate, rotate, scale and copy data
Print display to the default printer (points and entities only)
Version check in the Help menu for recent updates
Extensive Help files available in each routine dialogue box.
I invite you to download, preview and test the program from the link below.
Read the READMEFIRST file in the zip before installation.
Feel free to copy and distribute for non-commercial use.
It will install to, and may be run from a USB memory device.
I have some tutorial exercises if members are interested.
I welcome any questions, suggestions, feedback and bug reports.
Mount Martha, Victoria.
