datadem
I am in the process of writing my thesis on flood hazard preparedness and forecasting in South East Asia, specifically Thailand. My analysis requires a medium resolution (even better, high resolution) digital elevation model for Bangkok and vicinity areas.
Where can I find such data?
My internet search so far returns not DEM data but only finished maps from different organizations.
The 3-arc second (~90 meter) SRTM covers all of Europe to 60° N, has good positional accuracy and is part of the public domain. CGIAR provides an interface for easily downloading the data tiles, which are provided in both ASCII and GeoTIFF formats.
Country specified sites:
For Finland there is https://tiedostopalvelu.maanmittauslaitos.fi/tp/kartta it uses CC 4.0 License. Select korkeusmalli (elevation modell) (2m and 5m), or laserkeilusaineisto (LAS data)

I suggest Aster DEM for your purpose. You can download 30MX30M DEM from ASTER GDEM
