The Pima County Information Technology Department is pleased to introduce PimaMaps, Pima County's next generation web mapping system that will eventually replace the current MapGuide system. The Main MapGuide Map, will remain available for a substantial amount of time while PimaMaps is fully implemented. While MapGuide has been a very reliable web mapping system for many years, it is no longer supported by Autodesk. PimaMaps is based on new technology, provides a more robust and modern interface comparable to Google and Bing, and offers a richer set of functionality beyond what is available with MapGuide. This version of PimaMaps has the following functionality and enhancements that are not available with MapGuide:...
What are current conditions for important park natural resources? What are the critical data and knowledge gaps? What are some of the factors that are influencing park resource conditions? Natural Resource Condition Assessments (NRCAs) evaluate and report on the above for a subset of important natural resources in national park units (hereafter, parks). Focal study resources and indicators are selected on a park-by-park basis, guided by use of structured resource assessment and reporting frameworks. Considerations include park resource setting and enabling legislation (what are this park's most important natural resources?) and presently available data and expertise (what can be evaluated at this time?). In addition...

Geoinformación es un portal de información geográfica donde se puede consultar, visualizar y descargar cartografía temática de diferentes escalas generada y recopilada por CONABIO. Para desarrollar este portal se utilizó software de código abierto (open source). Las características principales del portal, son, desarrollar mecanismos de acceso a los acervos de datos geográficos de la CONABIO a través de servicios de información especializados, como: Vista gráfica de la información por temas generales. Información detallada sobre la cartografía disponible a través de búsquedas en los metadatos. Descarga de información en un formato compatible (shapefile) La información cartográfica es administrada por la Subdirección...

Web Soil Survey (WSS) provides soil data and information produced by the National Cooperative Soil Survey. It is operated by the USDA Natural Resources Conservation Service (NRCS) and provides access to the largest natural resource information system in the world. NRCS has soil maps and data available online for more than 95 percent of the nation’s counties and anticipates having 100 percent in the near future. The site is updated and maintained online as the single authoritative source of soil survey information. Soil surveys can be used for general farm, local, and wider area planning. Onsite investigation is needed in some cases, such as soil quality assessments and certain conservation and engineering applications....

The Southwest Regional Gap Analysis Project (SWReGAP) is an update of the Gap Analysis Program’s mapping and assessment of biodiversity for the five-state region encompassing Arizona, Colorado, Nevada, New Mexico, and Utah. It is a multi-institutional cooperative effort coordinated by the U.S. Geological Survey Gap Analysis Program. The primary objective of the update is to use a coordinated mapping approach to create detailed, seamless GIS maps of land cover, all native terrestrial vertebrate species, land stewardship, and management status, and to analyze this information to identify those biotic elements that are underrepresented on lands managed for their long term conservation or are “gaps.”

Pima County makes extensive use of Geographical Information System (GIS) technology for making maps. For the Sonoran Desert Conservation Plan, this was an important technology for assembling the extensive existing data, both digital and non-digital, identifying critical gaps in the data and potential remedies, and providing a means for analyzing the information on biological and physical resources over the six million acre study area. SDCP Mapguide was created to display many of the natural resource GIS data layers, but Mapguide is being replaced with PimaMaps. You can use either to make your own overlays on aerial photos, line maps, or USGS topography. Customize your online map while panning and zooming on the...

This data depicts highway locations in Alaska as digitized primarily from 1:24,000, 1:63,360, and 1:250,000 USGS quadrangles. The source document that represented the newest information and best geographic location was used to capture the data. All infrastructure from the primary source document was digitized and then supplemented with the information from other source documents for additional or updated infrastructure or attributes.
Goodstein identified and discussed a "Saturday effect" in data on the timing of tanker oil spills. This comment describes two ways in which the validity of the statistical analysis used to identify and confirm this effect can be strengthened.

NPScape is a landscape dynamics monitoring project that provides landscape-level data, tools, and evaluations for natural resource management, planning, and interpretation. The target audience for NPScape spans the range from GIS specialists who will benefit from the geospatial products, to ecologists and natural resource specialists who will be interested in the landscape metrics presented in a local and regional context, to park superintendents and other land managers who can incorporate the maps and graphics into reports or briefings.

Actualmente, el tema del agua reviste gran importancia por su escasez, degradación y riesgo que representan las avenidas de ríos, deslaves e inundaciones ocasionadas por lluvias intensas, además de considerarse un asunto estratégico para las políticas de los gobiernos. En este sentido y dada la necesidad de proveer información vectorial a mayor detalle como apoyo a lo mencionado, el INEGI generó la Red Hidrográfica escala 1:50 000 la cual modela el drenaje superficial de una cuenca hidrográfica, así como esta aplicación que permite a los usuarios consultar y analizar dicha información.
The rapid expansion of road networks has reduced connectivity among populations of flora and fauna. The resulting isolation is assumed to increase population extinction rates, in part because of the loss of genetic diversity. However, there are few cases where loss of genetic diversity has been linked directly to roads or other barriers. We analysed the effects of such barriers on connectivity and genetic diversity of 27 populations of Ovis canadensis nelsoni (desert bighorn sheep). We used partial Mantel tests, multiple linear regression and coalescent simulations to infer changes in gene flow and diversity of nuclear and mitochondrial DNA markers. Our findings link a rapid reduction in genetic diversity (up to...

The USGS Topo Large service from The National Map (TNM) is a dynamic topographic base map service that combines the best available data (Boundaries, Elevation, Geographic Names, Hydrography, Land Cover, Structures, Transportation, and other themes) that make up The National Map. Contours generated for the US Topo product are visible along with other data at scales of 1:13,500 and larger. This product is designed to provide a seamless view of the data in a geographic information system (GIS) accessible format, closely resembling The National Map US Topo GeoPDF product at large scales.

Transportation for Wyoming, including interstates, state and county highways, neighborhood and connecting roads, jeep trails, and other road and trail types, developed by the US Census at 1:100,000-scale. The Wyoming Water Resources Lab has tiled this information together by 1:100,000 quadrangles for Wyoming and created an attribute table which contains a description of the primary road/trail attribute, CFCC. A subset of this dataset is also available, including only federal and state highways for simplified display purposes. In order to reduce the size of this subset, the line segments were dissolved to remove unecessary segments. The data is available (both statewide and tiles) in ARC/INFO export file format and...

In response to concerns about rangeland fragmentation associated with exurban development, ranching families, agency representatives, and conservation groups have organized to address management concerns through the Malpai Borderlands Group (see: http://www.malpaiborderlandsgroup.org). This group promotes large acreage conservation easements throughout the region as means to promote rangeland connectivity. Shrub encroachment and long-term loss of grass productivity are primary natural resource concerns. Fire, which is facilitated in areas free of exurban development, is a key conservation practice. Additional practices include mechanical brush management, prescribed grazing, and erosion control structures. The conservation...
