Abstract

The paper proposes an integrated methodology for estimating mineral reserves based on UAV photogrammetry and RTK positioning technology. The methodology uses high-resolution digital elevation models, control points, and independent RTK measurements to improve the accuracy of volumetric calculations in conditions of complex topography and karst geology. Testing at limestone deposits in Vietnam confirms the effectiveness of the proposed approach.

Keywords

Photogrammetry, digital relief model, reserves assessment, limestone quarry.
