01 / Executive Summary
A web platform built for surveying professionals who need quick field math and trustworthy format conversion without uploading coordinate files. Six calculators work instantly with no account. Three converters handle GSI, CSV, and DXF entirely in your browser, with Learn articles and reference guides tied to each tool.
02 / Project Milestones
- Six public calculators — bearing/distance, traverse closure, Bowditch adjustment, Tienstra resection, column center, and polygon area — usable on phone or laptop with no sign-in.
- GSI ↔ CSV and CSV → DXF converters process files on your device; only file size and point count are sent to check credits, never the coordinates themselves.
- Fair credit billing: 30 free conversions per month, charged only after a successful download, with a five-minute window to re-export the same job to another format at no extra cost.
- Learn articles and GSI format reference paired to every calculator and converter — read the method, then run the tool on the same site.
