note = "Abstract: Urban air quality challenges represent the
second environmental priority of the European Commission
because of its effects on human health. With this premise,
this work developed in the context of the research project
TRAFAIR: Understanding traffic flows to improve air quality
(2017-EU-IA-0167) has focused on the processing and
publication of air quality monitoring data sets in the
prototype of the infrastructure deployed by the project for
the city of Zaragoza. Firstly, the sensor networks of the
monitoring systems for data collection have been
identified: the regulated stations of the Zaragoza City
Council and the low-cost sensors deployed by the TRAFAIR
project. Based on the data provided by the sensors, a
database model has been implemented for their storage.
Secondly, an architecture has been proposed for publishing
part of the data stored in the TRAFAIR database through the
Geoserver spatial data server. For this purpose, both
discrete phenomenon layers, partial views of the
information stored in the database, and spatial coverage
generated from interpolation algorithms have been modeled.
As for open access publishing, a software has been
implemented and adapted for the creation of the layers
through the Geoserver Rest API, which in turn has allowed
access to the data through standard services defined by the
Open Geospatial Consortium (OGC). For the dissemination of
the data in open data portals, we have also participated in
the implementation of a software to export the information
of the Geoserver layers as GeoDCAT-AP type metadata in CKAN
type servers. In addition, a strategy has been proposed to
distribute some data sets in specific formats (CSV, RDF,
NetCDF). Finally, the quality of the published spatial data
has been analyzed from different points of view: conformity
with the INSPIRE data specifications, quality of the
GeoDCAT-AP metadata from a methodology based on the
procedure used by the European Data Portal; analysis of the
completeness of the observations; and analysis of the
accuracy of the observations from the TRAFAIR project
sensors.",
