Usability of IoT and Open Data Repositories for Analyzing Water Pollution. A Case Study in the Czech Republic

Abstract

Recently, the process of data opening has intensified, especially thanks to the involvement of many institutions that have not yet shared their data. Some entities provided data to the public long before the trend of open data was pushed to a wider level, but many institutions have only engaged in this process recently thanks to a systemic state-level effort to make data repositories available to the public. Therefore, there are many new potential sources of data available for research, including the area of water management. This article analyses the current state of available data in the Czech Republic—their content, structure, format, availability, costs and other indicators that affect the usability of these data for independent researchers in the area of water management. The case study was conducted to ascertain the levels of accessibility and usability of data in open data repositories and the possibilities of obtaining data from IoT (Internet of Things) devices such as networked sensors where required data is either not available from existing sources, too costly, or otherwise unsuitable for the research. The goal of the underlying research was to assess the impact/ratio of various watershed factors based on monitored indicators of water pollution in a model watershed. Such information would help propose measures for reducing the volume of pollution resulting in increased security in terms of available drinking water for the capital city Prague.

Dados abertos governamentais: iniciativas e desafios na abertura de dados no Brasil e outras esferas internacionais

“…Já na República Tcheca, o Catálogo Nacional de Dados Abertos 14 criado em 2015 tem a incumbência de reunir os datasets governamentais, sanando dessa forma a grande descentralização das fontes de dados do país (Pavlík, Hrnčírová, Stočes, Masner, & Vaněk, 2020). O modelo de governança adotado para a publicação de dados abertos em todos os níveis de governo iniciou com forte coordenação central (de cima para baixo), mas atualmente os governos locais conduzem suas próprias iniciativas de dados abertos (Blank, 2019).…”

“…Isso ocorreria pelo fato de a maioria dos pequenos órgãos não ter a capacidade de publicar seus dados. Pavlík et al (2020) complementam a crítica a determinados pontos do portal federal, a saber: alguns formatos de dados disponíveis comprometem a interoperabilidade; muitos datasets encobertos por outros; além de que o acesso a alguns tipos de dados brutos só estão disponíveis para o público mediante pagamento de taxa.…”
