An excerpt from Reducing Cave Survey Data with a Hand Calculator, ASF Newsletter, Autumn, 1977, No. 75, pgs. 2-14
"ABSTRACT
The recent advent of a wide range of small electronic calculators greatly facilitates the mathematical reduction of survey data into X, Y and Z co-ordinates for plotting on a grid. presented here are the formulae and methods used for reducing traverse data, closing networks and simple loops, and triangulating inaccessible points. An appendix lists a series of programs for use with the Texas Instruments SR-52 programmable calculator.
…
APPENDIX
SUMMARY OF PROGRAMS FOR THE SR 52 CALCULATOR
…
The following programs were written specifically for the SR 52, but should be adaptable to other calculators provided they have sufficient memory registers and a long enough program memory (c.f. table 1). As the specific sequence of key steps would tend to vary from one calculator to another, only generalised flow charts are presented here.
…
THE PROGRAMS …
…
The TAPE TRAVERSE program …
…
The NETWORK CLOSURE program …
…
The SEGMENT or LOOP CLOSURE program …
…
The TRIANGULATION program …
…
These programs should be usable in similar or simplified form in a number of other programmable hand calculators. They could also be used (and expanded) with programmable desk-top calculators …
