A Spatial Data Infrastructure Integrating Multisource Heterogeneous Geospatial Data and Time Series:
(2016)
Abstract: Currently, the best practice to support land planning calls for the development of Spatial Data Infrastructures (SDI) capable of integrating both geospatial datasets and time series information from multiple sources, e.g., multi temporal satellite data and Volunteered Geographic Information(VGI). This paper describes an original OGC standard interoperable SDI architecture and a geospatial data and metadata workflow for creating and managing multisource heterogeneous geospatial datasets and time series, and discusses it in the framework of the Space4Agri project study case developed to support the agricultural sector in Lombardy region, Northern Italy. The main novel contributions go beyond the application domain for which the SDI has been developed and are the following: the ingestion within an a-centric SDI, potentially distributed in several nodes on the Internet to support scalability, of products derived by processing remote sensing images, authoritative data, georeferenced in-situ measurements and voluntary information (VGI) created by farmers and agronomists using an original Smart App; the workflow automation for publishing sets and time series of heterogeneous multisource geospatial data and relative web services; and, finally, the project geoportal, that can ease the analysis of the geospatial datasets and time series by providing complex intelligent spatio-temporal query and answering facilities.

As part of the development of the NSDI Strategic Plan, the FGDC held a series of NSDI Leaders Forums to engage leaders of key geospatial organizations in the early stages of the planning process, gather initial input, and seek continuing involvement. Sessions were held in March, June, and August 2013, and in August 2014. These meetings have been very helpful in providing a forum to discuss issues concerning the development of the NSDI and as a means to develop common understanding and approaches. Participating organizations included:
