Definition - What does ArcInfo mean?
AcIinfo Is a geographic information system (GIS) system developed by ESRI. It was first released in 1982. It provided a proving ground for many of the features used by geotechnical operators today. The final, stable version of ArcInfo was released in 2010 and the product was retired in 2012, when it was replaced by ArcGIS Pro, ArcGIS Enterprise and ArcGIS online, a software-as-a-service (SaaS) version of the product that requires no download.
Trenchlesspedia explains ArcInfo
ArcInfo provided users with full cartographic capabilities as well as the ability to present the subterranean world in "layers." These layers might represent the different strata beneath the surface. One map layer might represent obstructions; another layer, soil types and yet another, voids or underground watercourses – anything a driller might encounter while creating a bore. Each layer was based on the information provided by some form of geotechnical investigation. The drawback to ArcInfo was that it required an in-depth knowledge of Fortran, a rather complex programming language.
