Open Geotechniek Studio

Open Geotechniek Studio is a desktop application for Dutch geotechnical work: CPT soundings, boreholes, projects, and site drawings on a single CAD sheet.

Soundings & boreholes:

• GEF 1.x and BRO XML (CPT_O / CPT_O_DP) parsers
• Live charts of cone resistance (qc), local friction (fs), friction ratio (Rf), and pore pressure (u2)
• Robertson SBT soil-behavior-type classification per layer
• BHR borehole data from BRO XML, with soil-layer visualization (conforming to the Dutch NEN5104 standard)

Map & live data:

• Interactive map with direct BRO integration — load an area and every sounding and borehole around the visible viewport is fetched automatically
• Kadaster aerial imagery, BAG buildings, cadastral boundaries, AHN elevation, BGT topography, and historical aerial photos (2016-2025) as toggleable overlays

Reporting & drawings:

• Professional PDF sounding reports: cover page, coordinate table, overview map, per-sounding pages, Robertson SBT legend, metadata
• Site drawings on A2/A3 CAD paper with a professional title block and automatic scale-fit
• Request quotes: automatically picks the 3 nearest sounding companies from a catalog of 43 Dutch companies and opens a pre-filled quote request in your mail client

Open Geotechniek Studio is free and open source (MIT), part of the OpenAEC Foundation family of applications, and built with Tauri for a small, native footprint.
