Online stake-out and surveying calculations for mobile phones

[Charles NZ]

I'm a surveyor in NZ and have written a few pages that perform simple
stake out (setting-out) and surveying calculations. The pages are also
color mobile phone compatible so that they can be used in the field,
using just a basic phone.

The pages include:
- radial calculations (e.g. find centre using 3 points)
- linear calculations (e.g. intersection of 2 lines)
- stake-out calculations (e.g. pipe laser grade)
- generate coordinates (e.g. generate point coordinates on an arc)
- angle conversions

I would be most grateful for your comments and suggestions. The site
is at:
