Shop: Online Shopping for Vector and Georeferenced Historical Maps - Geographic Information System History Maps. Diciembre 2007. He estado unos días en el sur de Italia, en unas jornadas relacionadas con el concurso de un puente sobre un lago en la región de Basilicata (en cuanto tenga tiempo lo comentaré), y el azar arregló las cosas para que estuviera en Nápoles el primer domingo del mes de diciembre.

diciembre 2007

En medio del centro histórico de Nápoles está Spaccanapoli que va desde la plaza de Gesù Nuovo hasta la calle Duomo. Su espina dorsal es una calle estrecha que recibe distintos nombres a lo largo de su recorrido pero que comienza como Via B. Croce. Dado que me alojaba justamente en la plaza pude observar como, de forma continua, llegaban grupos y grupos que suponía de turistas ya que los comandaba un guía provisto del correspondiente paraguas, pañuelo, etc., y solían llevar algún distintivo que los diferenciaba tales como gorras o bolsos. Al principio eran pocos, pero luego el flujo era continuado y subían la cuesta hasta cuatro y cinco a la vez.

Urban Modeling with ArcGIS 3D Analyst and SketchUp This article describes what happened when 13 urban planning and architecture faculty members and students at Florida Atlantic University (FAU), who had no proficiency in CAD or GIS software, came together to create an interactive three-dimensional GIS for a portion of downtown Fort Lauderdale in only 12 days.

1-Interoperable Three-Dimensional GIS

A working integration of three-dimensional models with georeferenced databases holds great promise for physical planning and design. It allows for simulation, visualization, shadow studies, urban wind effects, and neighborhood compatibility studies. Esri has made significant strides in the functionality of the ArcGIS 3D Analyst extension (which includes the ArcScene and ArcGlobe applications). Let's describe the whole world! Geocaching - The Official Global GPS Cache Hunt Site. ASTER Imagery. Global Map NASA and Japan's Ministry of Economy, Trade and industry (METI) released the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model (GDEM) to the worldwide public on June 29, 2009.

ASTER Imagery

The GDEM was created by processing and stereo-correlating the 1.3 million-scene ASTER archive of optical images, covering Earth's land surface between 83 degrees North and 83 degrees South latitudes. The GDEM is produced with 30-meter (98-feet) postings, and is formatted as 23,000 one-by-one- degree tiles. The GDEM is available for download from NASA's EOS data archive and Japan's Ground Data System. In this colorized version, low elevations are purple, medium elevations are greens and yellows, and high elevations are orange, red and white.

Anthropogenic biomes - Encyclopedia of Earth. Anthropogenic biomes describe globally-significant ecological patterns within the terrestrial biosphere caused by sustained direct human interaction with ecosystems, including agriculture, urbanization, forestry and other land uses.

Anthropogenic biomes - Encyclopedia of Earth

Conventional biomes, such as tropical rainforests or grasslands, are based on global vegetation patterns related to climate. Now that humans have fundamentally altered global patterns of ecosystem form, process, and biodiversity, anthropogenic biomes provide a contemporary view of the terrestrial biosphere in its human-altered form. Anthropogenic biomes may also be termed "anthromes" to distinguish them from conventional biome systems, or "human biomes" (a simpler but less precise term). Humans and ecosystems Humans are the ultimate ecosystem engineers, routinely reshaping ecosystem form and process using tools and technologies, such as fire, that are beyond the capacity of any other organism. SEDAC - Last of the Wild: Home. Introduction Human influence is a global driver of ecological processes on the planet, on par with climatic trends, geological forces, and astronomical variations.

The Wildlife Conservation Society (WCS) and the Center for International Earth Science Information Network (CIESIN) at Columbia University have joined together to systematically map and measure the human influence on the Earth’s land surface today. Maps and Graphics at UNEP/GRID-Arendal. The GRID-Arendal Maps & Graphics Library is an on-going project to collect and catalogue all graphic products that have been prepared for publications and web-sites from the last 15 years in a wide range of themes related to environment and sustainable development.

There are currently 3022 graphics available in the database. Victims and affected people in Pakistan flood, August 2010 Seasonal fooding can occur along all the major watersheds in the Himalayan region (Figure 11–14). The largest problems occur in food prone areas with high population densities. This includes parts of northeast India, south-central Nepal, central and southern Pakistan, large parts of Bangladesh and lower reaches of the large rivers in China. Home - Modelur. Digital Elevation Models. Site Modeling in Context Place-Based design projects benefit from an understanding and representation of the local terrain.

Digital Elevation Models

Terrain data is surprisingly easy to obtain and convert into useful representations that may be used in GIS and also popular CAD and 3d modeling formats. This page discusses the how to obtain georeferenced terrain data for nearly anywhere in the world and georeferencd aerial photography within the United States. A few tools are presented for transforming these raster terrain models into: synthetic shaded relief images; contours for laser cutting; surfaces for 3d visualization, and editable breaklines that serve as the basis of earthwork and grading studies.

Some things you can do with digital elevation models Digital Elevation Models (DEMs) are a type of raster GIS layer.
