Remote sensing techniques offer practical and effective methods for determining land cover, density and quality attributes.
World Water Watch utilizes a host of satellite platforms to collect images at various levels of resolution and scale. These images provide terrain, cover and land use data critical to watershed and micro-basin delineation and analysis. Similarly, multi-spectral remote sensing provides primary and supplemental information on a wide variety of parameters influencing watershed hydrology and contaminant transport processes.
Aerial photographs and other data collection techniques are utilized or developed for site-specific applications. In all cases field verification surveys ensure data quality and reliability.
