D2.1: Upgraded guidelines for data pre-processing and population of metadata. Technical report.

Abstract

The first phase of the project is dedicated to gathering new bathymetric data sets such as survey data sets, composite DTMs, and Satellite Derived Bathymetry (also considered as composite DTMs) by all data providers. The data providers should populate all new data sets in the Catalogue services, namely survey data sets in the SeaDataNet based CDI Data Discovery & Access service and the composite DTMs in the Sextant CPRD Catalogue service. Once populated in these Catalogues, the data providers are requested to pre-process and grid the new data sets using the GLOBE software and following the EMODnet standards. These data sets, at least at a resolution of 1/32 arc minute grid, should be transferred by data providers to Regional Coordinators. The generation of Regional DTMs is divided over regional sea basin subgroups, each with a Regional Coordinator and a number of contributing data providers. Each Regional Coordinator will be responsible for a quality assessment and selection of the data contributions and the compilation of the Regional DTM using the GLOBE software. This process will start end February 2022 when all data providers have finalized their data gathering and population activities for the CDI and CPRD catalogues and will have undertaken pre-processing and gridding of their data sets for delivery as DTMs to the regional coordinators. In a later stage, the data providers also have to gather HR-DTMs which they have to enter in the Sextant HR-DTM Catalogue service.
