The heterogeneous nature of geospatial data makes the sharing of it across organizations a complex issue. As a standard means of geospatial data encoding, Geography Markup Language (GML) has been proposed by Open Geospatial Consortium (OGC), which facilitates sharing and exchange of geospatial information. With the proliferation of GML in many geospatial applications and storage support from th...

While free and open source software becomes increasingly important in geospatial research and industry, open science perspectives are generally less reflected in universities’ educational programs. We present an example of how free and open source software can be incorporated into geospatial education to promote open and reproducible science. Since 2008 graduate students at North Carolina State...

Geospatial databases include any data with reference to geocoordinate information. The geospatial data can either be digital raster images that represent the data on the earth in the form of pixels or digital vector data that is primarily from satellites. Due to the fact that many of the high-resolution satellites are commercial in nature, uncontrolled dissemination of the high resolution image...

Recent advances in Web-related technologies have significantly promoted the wide sharing and integrated analysis of distributed geospatial data. Geospatial applications often involve diverse sources of data and complex geoprocessing functions. Existing Web-based GIS focuses more on access to distributed geospatial data. In scientific problem solving, the ability to carry out geospatial analysis...

Liability in data, products, and services related to geographic information systems, spatial data infrastructure, location based services and web mapping services, is complicated by the complexities and uncertainties in liability for information system products and services generally, as well as by legal theory uncertainties surrounding liability for maps. Each application of geospatial technol...

The MWTP: Monterrey Weather, Traffic and Pollution Database contains a collection of historic weather conditions, and recent traffic and air pollution data of the metropolitan area of Monterrey, Mexico. Collected data includes: temperature, humidity, raining conditions, wind speed, travel distance, travel time, PM2.5, PM10, O3, among many others. As of February 2017, the MWTP database contained...

SPATIAL ARRANGEMENT AS A PART OF GEOSPATIAL FEATURE ONTOLOGIES Jonathan R. Clark, Ph.D George Mason University, 2012 Dissertation Director: Dr. Anthony Stefanidis The geospatial sciences have always employed ontologies to describe spatial data, conduct analysis, and to design the systems and methods for conducting geospatial operations. While research on geospatial ontologies has addressed non-...

As networking and data storage technologies advance, web services have become a commonplace for data mining and sharing in an e-business model. Compared with business information, geospatial information is normally overwhelmed by the sheer volume of data. There has been a great need for the integration of web services and geospatial information to provide a platform for geospatial information d...

Up-to-date geospatial information can help crisis management community to coordinate its response. In addition to data that is created and curated by experts, there is an abundance of user-generated, user-curated data on Social Web sites such as Flickr, Twitter, and Google Earth. User-generated data and metadata can be used to harvest knowledge, including geospatial knowledge that will help sol...
