[ ITALY ] – The National Geoportal

October 13, 2016

The national geoportal of ITALY

he National Geoportal of the Ministry of Environment and Protection of Land and Sea, operates within the regulatory framework established by Legislative Decree no. 32/2010 and subsequent amendments and additions, the Italian transposition of the European Directive 2007/2 / EC establishing an Infrastructure for Spatial Information in the European Community (INSPIRE).

Article.8 paragraph 2, of Legislative Decree no. 32/2010 provides that the National Geoportal is the national access point for the aims of the INSPIRE Directive thereby providing a basis for the competent authorities, third parties, and private citizens to seek the spatial information available.

The National Geoportal is at the core of a network architecture designed as a federated network in which each node is “connected” to the central access point that is the National Geoportal itself. The main goal is the creation of a widespread environmental geographic information system consisting of nodes which make available their own environmental spatial information by sharing its metadata: the management and updating of metadata, spatial data and related services are carried out that way by the administration that produces the data without any physical transfer of it. This network is made up mainly by public authorities which may, in this way, fulfill its institutional obligations regarding the planning and management of land and environment.


MAUI COLLEGE – Top 5 Reasons for GIS

October 13, 2016
  1. Save money and promote efficiency.

    “GIS is widely used to optimize maintenance schedules and daily fleet movements. Typical implementations can result in a savings of 10 to 30 percent in operational expenses through reduction in fuel use and staff time, improved customer service, and more efficient scheduling.” – ESRI Website

  2. Improve Communications.

    “GIS-based maps and visualizations greatly assist in understanding situations and in storytelling. They are a type of language that improves communication between different teams, departments, disciplines, professional fields, organizations, and the public.” – ESRI Website

  3. Make Clear Decisions.

    “GIS is the go-to technology for making better decisions about location. Common examples include real estate site selection, route/corridor selection, evacuation planning, conservation, natural resource extraction, etc. Making correct decisions about location is critical to the success of an organization.”  – ESRI Website

  4. Easily Track Data & Records.

    “Many organizations have a primary responsibility of maintaining authoritative records about the status and change of geography. GIS provides a strong framework for managing these types of records with full transaction support and reporting tools.”  – ESRI Website

  5. Manage Geographically.

    “GIS is becoming essential to understanding what is happening—and what will happen—in geographic space. Once we understand, we can prescribe action. This new approach to management—managing geographically—is transforming the way that organizations operate.”  ESRI Website

The IUCN Red List of Threatened Species – Spatial Data Download

October 12, 2016

The IUCN Red List of Threatened Species contains assessments for just over 76,000 species, of which about two-thirds have spatial data. This spatial data provided below is for comprehensively assessed taxonomic groups. It is important to note that some species such as those listed as Data Deficient are not mapped and subspecies are mapped within the parental species. The data is available as ESRI shapefiles format and contains the known range of each species. Ranges are depicted as polygons, except for the freshwater HydroSHED tables. The shapefiles contain taxonomic information, distribution status, IUCN Red List category, sources and other details about the maps (see metadata document).
