In this paper, we address some challenges of protracted loading times and reduced performance when managing large image sets delivered as output by popular meso-scale weather and air-quality models when used in graphic engines of associated software applications. Following an examination of several distinguished models' output, we introduce an innovative approach centered on a three-tier software system architecture, supplemented by strategies including lazy-loading, image compression, and load stream prioritizati...

The paper presents our findings during the adoption of e-learning in the National Geoinformation Center of Bulgaria (NGIC). It details the approach used to build a set of functionalities that produce and deliver online educational products to the customers of NGIC. The Center is a consortium of the national providers of Earth observation data with a purpose to design and co-develop integrated information products. NGIC's information system is being developed since 2019. It is built adopting the IT service manageme...

Establishment of geoinformation centers (GIC) that integrate data produced by various sources in the field of earth sciences intensified in the past decade, driven mainly by the advances in big data technologies. We present results of our studies on several leading national and quasi-national GIC, that we made with intent to extract a basic model of system architecture. Our notion was that such model would allow easier reuse of good practices when a new GIC is planned or when an existing one is optimized, and will...
