In complicated surveying situations, determining the best survey method can be difficult. This report examines the four survey methods, and it identifies seven crucial factors to consider when selecting a survey method.

This report describes various surveying methods with a focus on mining applications. It describes situations where satellite surveying offers an advantage over other survey methods.

This report lists all the recent accuracy studies conducted by PhotoSat and shows the relationship between ground control point density and PhotoSat survey grid accuracy for grids derived from photo pairs of the DigitalGlobe’s WorldView constellation. For detailed information on any of the studies, please see the respective report.

This report shows how monthly satellite surveying can be used to monitor TSF construction and operations. PhotoSat surveying provides an independent and auditable record that can facilitate future modifications of TSFs.

PhotoSat elevation grids derived from photo pairs remain highly accurate, even when ground control point density is low.  This report shows the relationship between ground control point density and survey elevation accuracy.

This report examines the worst survey errors in mining projects, from their root causes to solutions. It describes mining projects where undetected survey errors led to serious and costly delays in feasibility studies.

This case study shows how satellite surveying was used to address survey errors from 3 separate data sets. The updated survey facilitated the PEA and feasibility studies for the Diablillos project in Argentina.

This report shows how monthly satellite surveying can be used to monitor TSFs and maximize their capacity. It describes how PhotoSat measures tailings beach lift thicknesses and volumes.
