Dhabitat

Dhabitat is a coined term in ecological informatics describing a digital representation of a habitat used for modeling, simulation, and decision support. It treats habitat as a structured, machine-readable space that can be stored, queried, and updated as new data become available. The concept integrates spatial geometry, environmental context, and species information within a single data object to enable consistent analyses across projects and time scales.

A dhabitat typically includes a spatial layer (polygons, lines, or points) with a coordinate reference system, a temporal component for changes over time, biological data (occurrence, abundance, or occupancy), environmental covariates (climate, soil, land cover, topography), and rich metadata (provenance, licensing, methods, quality). Interoperability is central, using common formats (GeoJSON, Shapefiles) and standards (ISO 19115, Darwin Core) to enable sharing with GIS and modeling tools.

Applications include conservation planning, habitat connectivity and suitability analyses, and climate change impact assessments. Dhabitats support reproducible workflows by linking data, models, and results, and they inform policy regarding reserve design and land-use scenarios. Challenges include data gaps, scale mismatches between observations and models, uncertainty propagation, and governance or licensing barriers that limit data reuse.

Although not a formal standard, the dhabitat concept provides a practical framework for organizing diverse ecological data in digital form. Related concepts include habitat, habitat fragmentation, ecological modeling, GIS, and biodiversity informatics.
