Granumetrics

About

Granumetrics helps aggregate teams capture, review and report photo-based particle size distributions. Sign up for free, create your workspace and start with calibrated photos of coarse aggregate. You can also join a team’s workspace by invitation. Capture or import photos with a supported ChArUco calibration board or a ruler. Review the size distribution, D-values, sieve table, calibration warnings and detected particles before preparing a report. Features: - Guided capture with level and camera controls. - Multiple photos in one analysis. - Supported Large, Medium and Small calibration boards, plus ruler calibration. - Particle review with recorded inclusion and exclusion decisions. - Materials, analysis history and workspace sharing. - Draft reports, issued revisions, PDF reports and CSV exports. - Saved drafts and upload recovery. - Clear analysis allowances, with in-app requests for help. Photo PSD is an image-derived estimate. It is not a physical sieve test or a replacement for a test required by a contract or standard. Review calibration and results before relying on them. No advertising SDK is included. Limited technical diagnostics use Sentry with default personally identifying information disabled. See the privacy policy for the current data-handling description.
