Masek Imaging conducted a demo flight for Hanson Aggregates in Irwindale to demonstrate the power of aerial imagery. Hanson is a part of Global Heidelberg Cement Group, the largest producer of aggregates in the world. The plant in Irwindale is Hanson's West Region flagship mining location in California with about 2.5 million tons of rock mined in a year.    



March 8, 2017.  Water level is near all-time low but is expected to raise within the next few months.



Below are examples of aerial surveying work captured during a 20-min flight. 

Detailed orthomosaic map stitched from over 400 overlapping photographs using Drone Deploy software - full resolution map has over 235 mega pixels. Orthomosaic images "flatten" the curvature of earth to show an area without visible distortion. The maps can be used for monitoring stockpiles, planning future development of a new mining site, equipment count, and other site-specific applications.   



Images show relative elevation differences between the low (blue) and the high (red) areas in the map. For more precise information on a specific area, the range can be narrowed to show the area with a greater dynamic range. Narrowing the range can be useful for volume measurements when separating elevation layers, and allows for more precise tracking around material piles or other objects. Contour maps are also available but require the addition of GCP (ground control points) for absolute elevation measurements.   

Volume, Area, distance

Once the images are processed, a simple toolbox allows the user to draw a path around material piles or an area of interest to obtain calculations of distance, area, volume, cut, and fill. These measurements can be annotated, color coded, or sent to another person for review or adjustment. Comprehensive data sheets in a PDF form can be quickly created and shared with anyone involved.   


NDVI (normalized difference vegetation index) is calculated from the visible and near-infrared light reflected by vegetation. Healthy vegetation absorbs most of the visible light that hits it, and reflects a large portion of the near-infrared light. Unhealthy or sparse vegetation reflects more visible light and less near-infrared light
