Geoida - survey software for the Real World

Get your flat-earth surveys into better shape with

... because the Earth's not flat

Introducing Geoida

Geoida is a software product that will benefit members of the surveying and related professions for the day-to-day routine processing, coordination and adjustment of spatial survey data, from routine pick-up surveys to complex networks of geodetic scale.

Developed particularly for Australian requirements but with global application, Geoida uses rigorous geodetic formulae to coordinate points using user-definable parameters for any spheroid, geodetic datum or Transverse Mercator projection. Geoida reduces field observations, performs least-squares network adjustments, and converts and transforms coordinate data between different datums and systems. It also extracts and reports inverse details and exports point data in various formats suitable for other software. And it can also compute on the plane if required.

Geoida is a stand-alone product but can be used to complement other survey-CAD packages that do not provide geodetic computations, transformations or refined adjustments.

Geoida's Features
