Remote Sensing Software
A remote sensing software is a software application that processes remote sensing data. Remote sensing applications are similar to graphics software, but they enable generating geographic information from satellite and airborne sensor data. Remote sensing applications read specialized file formats that contain sensor image data, georeferencing information, and sensor metadata. Some of the more popular remote sensing file formats include: GeoTIFF, National Imagery Transmission Format, NITF, JPEG 2000, ECW (file format), MrSID, Hierarchical Data Format, HDF, and NetCDF. Remote sensing applications perform many features including: * Change Detection — Determining the changes from images taken at different times of the same area * Orthorectification — Warping an image to its location on the earth * Spectral Analysis — For example, using non-visible parts of the electromagnetic spectrum to determine whether a forest is healthy * Image Classification — Categorizing pixels based up ...

Virtual Globes
A virtual globe is a three-dimensional (3D) software model or representation of Earth or another world. A virtual globe provides the user with the ability to freely move around in the virtual environment by changing the viewing angle and position. Compared to a conventional globe, virtual globes have the additional capability of representing many different views of the surface of Earth. These views may be of geographical features, man-made features such as roads and buildings, or abstract representations of demographic quantities such as population. On November 20, 1997, Microsoft released an offline virtual globe in the form of Encarta Virtual Globe 98, followed by Cosmi's 3D World Atlas in 1999. The first widely publicized online virtual globes were NASA WorldWind (released in mid-2004) and Google Earth (mid-2005). Types Virtual globes may be used for study or navigation (by connecting to a GPS device) and their design varies considerably according to their purpose. Those ...

OpenStreetMap
OpenStreetMap (abbreviated OSM) is a free, Open Database License, open geographic database, map database updated and maintained by a community of volunteers via open collaboration. Contributors collect data from surveying, surveys, trace from Aerial photography, aerial photo imagery or satellite imagery, and import from other freely licensed geodata sources. OpenStreetMap is Free content, freely licensed under the Open Database License and is commonly used to make electronic maps, inform turn-by-turn navigation, and assist in humanitarian aid and Data and information visualization, data visualisation. OpenStreetMap uses its own data model to store geographical features which can then be exported into other GIS file formats. The OpenStreetMap website itself is an Web mapping, online map, geodata search engine, and editor. OpenStreetMap was created by Steve Coast in response to the Ordnance Survey, the United Kingdom's national mapping agency, failing to release its data to the pub ...

Geo-wiki
Geo-Wiki is a platform for engaging citizens and experts in both environmental and socioeconomic monitoring, established in 2009 at the International Institute for Applied Systems Analysis (IIASA). It aids in both, the validation of existing geographical information and the collection of new geographical information through crowdsourcing and citizen science. Using data sources such as satellite imagery, geotagged photographs and the Internet, individual volunteers are able to contribute valuable in-situ data, either by validating existing data and comparing it with satellite imagery (through visual interpretation), or by collecting new information. Other methods for crowd-sourced data collection in Geo-Wiki include campaigns and games, used as incentives to motivate citizens. Collected data in the platform is freely available. By 2020, Geo-Wiki had more than 15 000 registered contributors, and many successful citizen science campaigns, collecting data on topics such as global bui ...

Google Map Maker
Google Map Maker was a map editing service launched by Google in June 2008. In geographies where it is hard to find providers of good map data, user contributions were used to increase map quality. Changes to Google Map Maker were intended to appear on Google Maps only after sufficient review by Google moderators. Google Map Maker was used at Google Mapathon events held annually. In November 2016, Google announced that Google Map Maker would be retired and merged with Google Maps. Google Map Maker was officially shut down on March 31, 2017. Interface Using the find or browse tools, contributors were able to add and draw features directly onto a map where the borders had already been drawn, and could add features such as roads, railways, rivers and so on. In addition, users could add specific buildings and services onto the map such as local businesses and services. Three kinds of drawing tools were available: placemark (a single point of interest on the map), line (for drawing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collaborative Mapping
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. Volunteers collect geographic information and the citizens/individuals can be regarded as sensors within a geographical environment that create, assemble, and disseminate geographic data provided voluntarily by the individuals. Collaborative mapping is a special case of the larger phenomenon known as crowd sourcing, that allows citizens to be part of collaborative approach to accomplish a goal. The goals in collaborative mapping have a geographical aspect, e.g. having a more active role in urban planning. Especially when data, information, knowledge is distribut ...

Digital Elevation Model
A digital elevation model (DEM) or digital surface model (DSM) is a 3D computer graphics representation of elevation data to represent terrain or overlaying objects, commonly of a planet, Natural satellite, moon, or asteroid. A "global DEM" refers to a discrete global grid. DEMs are used often in geographic information systems (GIS), and are the most common basis for digitally produced Relief mapping (computer graphics), relief maps. A digital terrain model (DTM) represents specifically the ground surface while DEM and DSM may represent tree top Canopy (biology), canopy or building roofs. While a DSM may be useful for Landscape planning, landscape modeling, Urban planning, city modeling and visualization applications, a DTM is often required for flood or drainage modeling, Land-use planning, land-use studies, geological applications, and other applications, and in planetary science. Terminology There is no universal usage of the terms ''digital elevation model'' (DEM), ''di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
