Landcover and Vegetation, Ruby Lake NWR This dataset represents vegetation and landcover for Ruby Lake NWR. It was produced by the U.S. Fish and Wildlife Service, with field data collection provided by the University of Nevada, Reno. The process was iterative and took place over two calendar years and two field seasons. Additional data points were acquired in order to validate the map product and to develop a product that met a minimal accuracy level of 80%. The final classification is based on 2013 National Agricultural Imagery Program (NAIP) orthophotography, produced by the U.S. Department of Agriculture but additional datasets were also utilized, including a digital elevation model. The classification methodology uses a hybrid approach of pixel-based...

Depths were surveyed with a single-beam echo sounder and real-time kinematic global positioning system (RTK-GPS) along planned transects at predetermined intervals for each reservoir. A separate set of echo sounder data was collected along transects at oblique angles to the main transects for accuracy assessment. Field survey data was combined with water-surface elevations in a geographic information system to create three-dimensional surfaces representing reservoir-bed elevations in the...

The process involved interviewing wildlife movement and connectivity experts from state and federal agencies, and independent biologists with proven knowledge of wide-ranging wildlife. The experts were asked to use their professional and personal experience in the field (knowledge of related scientific studies and their own field research) to identify important areas of wildlife connectivity ("linkages" - defined as as a specific area through which...

Dentro de este Marco Institucional es que en 1992 se propone el desarrollo de un Sistema de Información Geográfica del Agua (SIGA) que se constituyera en una herramienta que permitiera integrar, consultar, analizar y desplegar la información georreferenciada para que las unidades de la CONAGUA realizaran con mayor eficiencia las labores de planeación y administración del agua.
