Constructor University is a private, English-speaking campus university in Germany.
Its aim is to strengthen people and markets with innovative solutions and advanced training programs.
Students from more than 120 nations join the vibrant international community.
The Large-Scale Scientific Information Systems Research Group
innovates on flexible, scalable, federated services for massive multi-dimensional data, often called "datacubes".
A main result is the pioneer Array Database System, rasdaman.
Further, the group leads datacube standardization in OGC and ISO, and contributes critically to the European SDI initiative, INSPIRE.
The rasdaman endpoint hosted by Constructor University Bremen provides
access to a diverse collection of geospatial datacubes ranging from global
climate models and satellite imagery to localized digital surface models.
The catalog includes high-dimensional datasets such as Temperature4D,
which offers four-dimensional atmospheric temperature data spanning time,
elevation, latitude, and longitude, alongside multi-temporal global
coverages like AvgLandTemp and AvgTemperatureColor that track
environmental changes from 2000 to 2015. Additionally, the service hosts a
sample of Sentinel-2 Level-2A imagery (S2_L2A_32631_*) for a specific
region in Europe, capturing multiple spectral bands (B01, B03, B04, B08,
B12) and true color composites with high temporal resolution from April
2021.
The available datacubes vary in dimensionality, spatial extent, and format
support, accommodating both global grids and localized rectified grids.
While many datasets utilize the standard WGS84 coordinate system
(EPSG:4326), others are projected using UTM zones (e.g., EPSG:32631,
EPSG:32632) or abstract index spaces for specific analytical needs, such
as the 1D time-series test_365_days_irregular or the 3D climate models
climate_cloud and climate_earth. The service supports a wide array of
output formats including NetCDF, JPEG2000, GeoTIFF, and JSON, and offers
advanced processing capabilities such as interpolation, scaling, and
subsetting, enabling users to retrieve tailored subsets of large-scale
datasets like the multi-gigabyte land_cover_class__esa_test_6 or the
high-resolution global temperature map world_temp_high_res.
