Hi, my name is

Cemal Melih Tanis.

I build and manage Earth Observation services.

I'm a Geospatial Engineer based in Finland with over a decade of experience specializing in remote sensing, GIS, and the delivery of operational data services that turn complex satellite data into reliable, actionable information.

About Me

With a background in Electronics Engineering and a Master's in Space Science, my career has been dedicated to the practical application of technology in Earth Observation. For over 11 years at the Finnish Meteorological Institute, I have been at the forefront of developing and maintaining operational services that are critical for monitoring our planet's cryosphere and hydrological systems.

My work involves not just deep technical analysis and algorithm development, but also leading FMI's contributions to major international projects. This experience has cultivated a passion for not only solving technical challenges but also for improving processes and fostering collaboration.
