A geographic information system (GIS) consists of integrated computer hardware and software that store, manage, analyze, edit, output, and visualize geographic data. Much of this often happens within a spatial database, however, this is not essential to meet the definition of a GIS. In a broader sense, one may consider such a system also to include human users and support staff, procedures and workflows, the body of knowledge of relevant concepts and methods, and institutional organizations.
Geologic modelling,geological modelling or geomodelling is the applied science of creating computerized representations of portions of the Earth's crust based on geophysical and geological observations made on and below the Earth surface. A geomodel is the numerical equivalent of a three-dimensional geological map complemented by a description of physical quantities in the domain of interest. Geomodelling is related to the concept of Shared Earth Model; which is a multidisciplinary, interoperable and updatable knowledge base about the subsurface.
Geoinformatics is a scientific field primarily within the domains of Computer Science and technical geography. It focuses on the programming of applications, spatial data structures, and the analysis of objects and space-time phenomena related to the surface and underneath of Earth and other celestial bodies. The field develops software and web services to model and analyse spatial data, serving the needs of geosciences and related scientific and engineering disciplines. The term is often used interchangeably with Geomatics, although the two have distinct focuses; Geomatics emphasizes acquiring spatial knowledge and leveraging information systems, not their development. At least one publication has claimed the discipline is pure computer science outside the realm of geography.
A GIS software program is a computer program to support the use of a geographic information system, providing the ability to create, store, manage, query, analyze, and visualize geographic data, that is, data representing phenomena for which location is important. The GIS software industry encompasses a broad range of commercial and open-source products that provide some or all of these capabilities within various information technology architectures.
ArcGIS is a family of client, server and online geographic information system (GIS) software developed and maintained by Esri.
Land cover is the physical material at the surface of Earth. Land covers include grass, asphalt, trees, bare ground, water, etc. Earth cover is the expression used by ecologist Frederick Edward Clements that has its closest modern equivalent being vegetation. The expression continues to be used by the United States Bureau of Land Management.
Participatory rural appraisal (PRA) is an approach used by non-governmental organizations (NGOs) and other agencies involved in international development. The approach aims to incorporate the knowledge and opinions of rural people in the planning and management of development projects and programmes.
Participatory GIS (PGIS) or public participation geographic information system (PPGIS) is a participatory approach to spatial planning and spatial information and communications management.
Web mapping or an online mapping is the process of using, creating, and distributing maps on the World Wide Web, usually through the use of Web geographic information systems. A web map or an online map is both served and consumed, thus, web mapping is more than just web cartography, it is a service where consumers may choose what the map will show.
Participatory planning is an urban planning paradigm that emphasizes involving the entire community in the community planning process. Participatory planning emerged in response to the centralized and rationalistic approaches that defined early urban planning work.
Collaborative mapping, also known as citizen mapping, is the aggregation of Web mapping and user-generated content, from a group of individuals or entities, and can take several distinct forms. With the growth of technology for storing and sharing maps, collaborative maps have become competitors to commercial services, in the case of OpenStreetMap, or components of them, as in Google Map Maker Waze and Yandex Map Editor.
Traditional knowledge geographic information systems (GIS) are the data, techniques, and technologies designed to document and utilize local knowledges in communities around the world. Traditional knowledge is information that encompasses the experiences of a particular culture or society. Traditional knowledge GIS differ from ordinary cognitive maps in that they express environmental and spiritual relationships among real and conceptual entities. This toolset focuses on cultural preservation, land rights disputes, natural resource management, and economic development.
Volunteered geographic information (VGI) is the harnessing of tools to create, assemble, and disseminate geographic data provided voluntarily by individuals. VGI is a special case of the larger phenomenon known as user-generated content, and allows people to have a more active role in activities such as urban planning and mapping.
A geographic data model, geospatial data model, or simply data model in the context of geographic information systems, is a mathematical and digital structure for representing phenomena over the Earth. Generally, such data models represent various aspects of these phenomena by means of geographic data, including spatial locations, attributes, change over time, and identity. For example, the vector data model represents geography as collections of points, lines, and polygons, and the raster data model represent geography as cell matrices that store numeric values. Data models are implemented throughout the GIS ecosystem, including the software tools for data management and spatial analysis, data stored in a variety of GIS file formats, specifications and standards, and specific designs for GIS installations.
The Indigenous Peoples of Africa Co-ordinating Committee (IPACC) was founded in 1997. It is one of the main trans-national network organizations recognised as a representative of African indigenous peoples in dialogues with governments and bodies such as the UN. As of 2008, IPACC was composed of 150 member organisations in 21 African countries.
Geographic Information Systems (GIS) has become an integral part of aquatic science and limnology. Water by its very nature is dynamic. Features associated with water are thus ever-changing. To be able to keep up with these changes, technological advancements have given scientists methods to enhance all aspects of scientific investigation, from satellite tracking of wildlife to computer mapping of habitats. Agencies like the US Geological Survey, US Fish and Wildlife Service as well as other federal and state agencies are utilizing GIS to aid in their conservation efforts.
Participatory Web 2.0 for development was a term coined around 2007-2008 to describe new ways of employing legemvweb services, in order to improve information sharing and collaborative production of content in the context of development work. Emerging developments in participatory Web and user-generated content platforms were seen to create conditions by which actors in development could easily relate to other stakeholders, have selective access to information, produce and publish their own content and redistribute pieces of content released by others. At this time, new social tools, such as wikis, blogs, and other user-generated content platforms, were first being considered for their ability to help development actors integrate, combine, aggregate, generate, moderate and mediate content. In a typical Web2forDev scenario data and/or functionalities from a number of free/low cost online applications are combined and served as mashups thus ensuring a wide range of online services at low cost. The term is no longer used in the development informatics or ICT4D fields.
Ramón Jesús Palmiano Paje is a Filipino civil servant. He was the 19th secretary of the Department of Environment and Natural Resources (DENR) under the administration of President Benigno Aquino III. Prior to his appointment, he was DENR Undersecretary for Field Operations and Executive Director of the Minerals Development Council under the Office of the President in concurrent capacity.
Geographic information system (GIS) is a commonly used tool for environmental management, modelling and planning. As simply defined by Michael Goodchild, GIS is as "a computer system for handling geographic information in a digital form". In recent years it has played an integral role in participatory, collaborative and open data philosophies. Social and technological evolutions have elevated digital and environmental agendas to the forefront of public policy, the global media and the private sector.
Counter-mapping is creating maps that challenge "dominant power structures, to further seemingly progressive goals". Counter-mapping is used in multiple disciplines to reclaim colonized territory. Counter-maps are prolific in indigenous cultures, "counter-mapping may reify, reinforce, and extend settler boundaries even as it seeks to challenge dominant mapping practices; and still, counter-mapping may simultaneously create conditions of possibility for decolonial ways of representing space and place." The term came into use in the United States when Nancy Peluso used it in 1995 to describe the commissioning of maps by forest users in Kalimantan, Indonesia, to contest government maps of forest areas that undermined indigenous interests. The resultant counter-hegemonic maps strengthen forest users' resource claims. There are numerous expressions closely related to counter-mapping: ethnocartography, alternative cartography, mapping-back, counter-hegemonic mapping, deep mapping and public participatory mapping. Moreover, the terms: critical cartography, subversive cartography, bio-regional mapping, and remapping are sometimes used interchangeably with counter-mapping, but in practice encompass much more.
