ScaleApp is a software engineering company based in Thessaloniki, Greece. We design, develop and operate production software systems, with particular expertise in Earth Observation, geospatial infrastructures and data processing platforms.
In these production environments we met a recurring problem. In one case, a map service feeding a precision agriculture application answered every request with HTTP 200. Every dashboard showed green and no alert fired, yet the maps never reached the application. Nobody noticed until the end user did.
Geospatial data fails in ways that generic monitoring does not see. A valid response can carry empty tiles. Data can fall outside the area of interest, use the wrong coordinate reference system, or arrive on time with values that have stopped changing. Finding these failures means reading each response as geospatial data.
IT monitoring confirmed that systems were running. Domain experts assessed the scientific quality of the data. Neither provided continuous verification of what operational services actually delivered.
We built SPHEROID to close that gap. It checks delivered data and services against defined requirements: availability and completeness, spatial consistency, freshness, service behaviour and metadata. It compares each delivery with the service's own history and keeps the evidence behind every result. It runs read-only, alongside existing monitoring and scientific validation.


Alongside SPHEROID, we continue to design, integrate and support production software systems, combining software architecture, data engineering and operational expertise.
Our engineering work and product development reinforce each other, connecting practical production experience with tools designed to address real operational challenges.
From applications on European Earth Observation infrastructure to operational geospatial platforms and enterprise systems, we engineer software designed to perform reliably in production. Each entry states ScaleApp's role. Named references are available on request during procurement.
