## Description

Survey Calculator Pro is a versatile and essential Chrome extension designed for land surveyors and transportation engineering professionals. It provides a comprehensive suite of calculation tools required for accurate fieldwork, including bearing distance conversions between rectangular and polar coordinates, intersection point calculations, and reference line computations. The extension supports importing Civil 3D LandXML alignment data to handle complete road, bridge, or railway alignments with precision.

Key features include calculators for 3-point circles, circular and spiral curve setting out, vertical curves, and 2D transformations for coordinate system changes. Additional utilities such as area calculation by coordinates, Bowditch rule traverse adjustments, triangulation coordinate computation, and latitude-longitude to UTM conversions make this tool indispensable for surveyors. The extension emphasizes accuracy through careful data input and recommends verification with other platforms before project application.
