Abstract
Primarily driven by current advances in web, web service and sensors technologies, and the expressed needs from geospatial and broader communities, the webbased sensors and geoprocessing service fields have evolved rapidly over the last 10 years. Geoprocessing services greatly facilitate the process of transforming geospatial data to geoinformation, exposing the powerful analytic capability of geographic information system (GIS) and empowering the public in today’s “electronic” decision-making over the worldwide web, particularly within spatial data infrastructure frameworks, through service composition, utilization of advanced grid/cloud computing, and well-designed client-side applications. The research topics and issues range from discovery, accessibility, usability to interoperability, which require standards support, and cooperation among academia, industry, government, commercial, and open source communities. This special issue builds on the extended version of seven papers selected from the papers submitted to the first International Workshop on Pervasive Web Mapping, Geoprocessing and Services, which was successfully held on the Politecnico di Milano campus in Como, Italy fromAugust 26 to 27, 2010. The workshop was organized by ISPRS WG IV/5 on “Distributed, Web-based Geoinformation Services and Applications” and Politecnico di Milano, and coorganized by ISPRS WG WG IV/1 on “Geospatial Data Infrastructure”, WG IV/4 on “Virtual Globes and Context-Aware Visualization”, and ICWG IV/II on “Geo-Sensor Networking and GEOGRID”. The main theme of the workshop focused on Sensor Web Enablement and Geoprocessing Services. Some of the particular topics and issues addressed in the technical sessions included (full papers are available at http://www.isprs.org/ proceedings/XXXVIII/4-W13/):
