Data value enhancement for Amazonia drainage datasets

The three Americas have 46% of all the world fresh water. South America has 60% of three Americas fresh water regarding 27.6% of world fresh wa-ter. Brazil has 28% of America's fresh water and 12% of world fresh water. The existence of this huge amount of water is directly related to various situations of floods, occurring in cities and in rural areas, at fast or slows pace. Those floods, which can cause major social and economic damage, must be studied and whenever possible prevented. This work aims to illustrate the planned activity of a bilateral collaboration between two Brazil (INPE) and Italian (CNR-IMATI) Institutions aiming at identifying methodologies fostering drainage data sharing, use and re-usage at different stages of the data processing pipelines in order to create a seamless cross-sectorial data "provider/consumer" chain. In particular, it illustrates the preliminary results of the research activities aiming at making available South America drainage network data and the Amazonian basin. Such data, produced by the TerraHidro tool developed by INPE, is going to be published as Open Data, thus addressing the implementation of the Bra-zilian e-government initiative about data transparencies according to Law no. 12.527, of November 18, 2011. The strategy of Brazil and the European Commission about "free and open public access of information" are also take into account. Moreover, the Implementing Rules of INSPIRE are considered in order to meet the scientific and technological policy between Brazil and European Commission. The approach aims at producing, publishing and reusing territorial infor-mation created by INPE about drainage resources. In a medium-long term, this methodology aimed at establishing a consolidated point of access of territorial interlinked maps and geo-localized data and metadata-related information. The implemented strategy foresees: o"Documentation of data with proper metadata needed for third party application", by covering issues such as provenance, quality, versioning (e.g., GEO-DCAT-AP, W3C-DQV, W3C-PROV); o"Fostering the data publication on the Web according to the (Linked) Open Data initiative", by adopting W3C best practices for (Spatial) Data on the Web; o"Data semantic enrichment" considering Linked Data and ontology as lightweight Semantic Web tools for the semantic enrichment of the Drainage Data. The expected result is an enrichment of drainage datasets, and in particular of Amazonia with 5m resolution produced by INPE, enhancing data dissemination among the different communities working on cross-target discipline (e.g. climate change, water.
