About sitemath.net: Built for the Field, By a Surveyor
Hi, I’m George, the creator of sitemath.net.
As a professional surveyor with a background in mining and construction, I spend my days working with complex coordinate geometry, structural tolerances, and bulk point data.
I built this website out of personal necessity. Whether I was in the field or back in the site office, I constantly found myself needing to run calculations that some of the available software I had access to could not do – like calculating the centre of a 3d circle, or simply being able to adjust a dumpy level run that ended on a different point.
sitemath.net is a collection of the exact Coordinate Geometry (COGO) and spatial calculators that I use in my own professional life every day.
The SiteMath Philosophy
Everything on this site is built with a few core principles in mind:
- Frictionless Input: You shouldn’t have to manually type in coordinates one by one. Where possible, my calculators are built with bulk data directly from your CSV data file.
- Rigorous Math: We don’t use simple spreadsheet trendlines. From Orthogonal Distance Regression to Gauss-Newton least squares matrices, the background math is engineered for survey-grade accuracy.
- Actionable Outputs: Numbers in a browser are good, but field records are better. Every tool is built with a batch-saving memory and a clean, tabular CSV export so you have a hard copy for your QA/QC records.
These tools have saved me hours, and my goal is to help other surveyors, civil engineers, and site managers do the same.
If you have a suggestion for a new calculator or feedback on how to make an existing tool work better for your daily workflow, I would love to hear from you.
