  • An approach to quantifying rainwater harvesting potential using imagery, geographic information systems (GIS) and LiDAR data

    Geographic Information Systems (GIS) software is used to analyze rainwater harvesting potential in Escambia County, Florida, USA. The approach presented can be replicated using LiDAR data, and the infrared spectrum of National Agriculture Imagery Program (NAIP) imagery. GIS surface maps are analyzed in combination with local utility consumption data to determine potential reductions in potable ...

  • New Maps from Old Photos: Measuring Coastal Erosion

    U.S. Geological Survey scientists and their coauthors from the California Coastal Records Project have found a way to use historical aerial photographs not just to see evidence of coastal erosion, but to accurately measure how much has occurred over time. Applying a low-cost technique called “structure-from-motion” to five sets of oblique aerial photos spanning the years ...

  • Smart LDAR — more cost-effective?

    On December 19, 2008, EPA issued a final rule establishing a voluntary Alternative Work Practice (AWP) to detect leaks of volatile organic compounds (VOC) and hazardous air pollutants (HAP) from process equipment (FR Vol. 73, Number 246), thereby providing the regulated community additional flexibility in complying with leak detection and repair (LDAR) requirements. The AWP allows owners or ...

  • Micro Pulse LiDAR Monitors Air Quality at Mining Sites in Real Time - Case Study

    Early Detection of Adverse Particulate Matter Aids Dust Management Dust emissions at open-cut coal mines are a potential threat to air quality in surrounding areas. To learn more about particulate matter (PM) and how it travels beyond a mine’s boundaries, a research grant from the Australian Coal Association Research Program (ACARP) was awarded to Pacific Environment, an environmental ...
