New Geo APIs - 10/31/12
Environment Canterbury GIS API: The service is provided by the Environment Canterbury Regional Council, a regional authority within New Zealand. It exposes geographic information service (GIS) data for open public access. GIS services available include OGC-compliant map services for standardized access by GIS clients and applications. Datasets make available aerial photography, regional planning zones, natural resources profiles, and more.
API methods support access to a number of interrelated datasets, including color aerial photographs and planning zone boundaries. Natural resources within the region are documented, as are existing permitted uses. Environmental monitoring stations and other facilities are mapped.
SolarGIS API: SolarGIS is a geographic information system designed to meet the needs of the solar energy industry. It integrates solar resource information and meteorological data with tools for planning and monitoring the performance of solar energy systems. SolarGIS data covers most of the globe, but does not yet cover Canada, the United States, Japan, parts of Australia, and a few other regions. SolarGIS is trying to achieve global coverage by the end of 2012.
To provide clients with additional means of accessing their tools and data, SolarGIS has developed the Data Delivery and PV Planner Calculate APIs. The Data Delivery API retrieves the most recent data from the SolarGIS database and calculates the electrical output of a PV (photovoltaic) system. The PV Planner Calculate API is a simulation tool for the planning and optimization of PV systems.
MnGeo Composite Image API: The service provides aerial and satellite photos depicting terrain within the U.S. state of Minnesota. It works through a single access point that automatically provides appropriate photos taken from aircraft or by earth-orbiting satellites, depending on the space covered in the request and the resolution or level of detail requested. Images are available for locations across the state, with emphasis on the Twin Cities of Minneapolis-St. Paul. Some images are available of terrain bordering Minnesota, especially counties in Wisconsin near the Twin Cities. Images are used, for example, in the Interactive Twin Cities Transit Map from Metro Transit.
API methods support access to imagery from the 7-country Twin Cities metro area and 4 counties to its north, 37 counties across Minnesota and near its eastern border, and areas within Canada along the state's northern border. Resolutions vary from 1:10,000 aerial photographs to FSA NAIP satellite photos up to 1:250,000 to even larger scale Landsat photos.
MnGeo Geospatial Image API: The service provides a repository of aerial photos and topographic maps of terrain within the U.S. state of Minnesota. Photographs are taken from aircraft to capture surface features, and topographical maps are scanned from authoritative printed versions. The Web Map Service (WMS) stores and provides access to very large image files, saving the need to download and save local copies.
API methods support access to digital orthophotography and hillshade images as well as scanned USGS quadrangle topographic maps for locations in Minnesota specified by latitude and longitude or UTM zone. Returned data compliant with WMS protocols provide links to image files in jpeg and png formats.
DiscoverEDINA Tagger API: The service extracts and gives access to metadata stored with document and resource files, especially image and multimedia files. Digital cameras and other image creation devices generate extensive descriptive data about how the file was created, including the device, resolution, format, date and time, geographic location, etc. This data is stored invisibly with the file, but may be accessible either for intended uses or for unintended ones such as discovering a location that should have remained secret. The service both shows what data is accessible with the stored file and enriches that data with additional descriptive information.
API methods support uploading a file and reviewing all descriptive metadata it provides. Methods also allow addition, revision, or deletion of selected metadata including addition, purging, or obscuring of geolocation information. The API also supports exporting of metadata for use separate from the file itself and search for images within the system created near the location of a selected image.
NREL National Solar Radiation Database API: The service from the U.S. National Renewable Energy Laboratory (NREL) provides access to a database of solar radiation available at locations within the United States. The National Solar Radiation Database (NSRDB) lists recorded solar energy readings from a wide range of weather stations. Data are summarized based on readings captured 1991-2005 using the Typical Meteorological Year (TMY) methodology.
API methods support search for solar radiation data for a location specified by latitude and longitude. Results can be restricted to specific fields such as date and time of recordings, specific recording station, solar conditions such as zenith and illumination, and weather conditions like precipitation and barometric pressure.
