Capture investigations on site, sync data to a single secure database, process data, and publish professional logs and reports — across mobile and desktop. Licensed on a subscription basis, on your own Microsoft SQL Server®.
Log on a phone or tablet in the field, sync to the office, manage and process on the desktop, and produce polished borehole logs, CPT logs and core photo sheets, 3D models and sections — all driven by the same central database.
CORE-GS runs on your own Microsoft SQL Server® — on-premises or in your Azure tenant. Your licence to the database is permanent, the APIs run in your tenant against your own identity provider, and we never train models on your data. Whatever happens to your subscription, everything you put in stays yours and stays usable.
And as we explore AI and machine learning, you stay in control there too — any such features are pre-release and optional, and we’ll always give you ways to control how they work and whether they touch your data.
We go far beyond generic logging software. CORE-GS manages spatial project data, in-situ tests, laboratory results, site notes and reporting — with the rigour engineering teams demand.
Record and preview reports of investigations, CPTs and lab tests on site, sync to the office, and review and issue to clients without re-keying a thing.
Import and export across AGS3 and AGS4, CPT systems, KML/KMZ, CSV, Excel, Access/gINT®, and CAD and model formats including DWG/DXF, LAS, OBJ, STL and TIN.
Microsoft SQL Server® storage with project-level permissions, on your own infrastructure, with a permanent licence to the database. We never train models on your data.

I have been using CORE-GS for almost five years and I am really impressed with the advantages offered by the software and, most of all, the development team at Geroc. In my experience, CORE-GS is second to none of the equivalent programs.
I haven’t had this much fun producing logs in the last 10 years!
I evaluated various drilling database solutions on a matrix including data import, customisable reporting, price and support. After trialling three products, Geroc Core-GS was selected. Would I recommend Core-GS to others — Yes.
