Datasets: attributes#
Entities: parcels, buildings, etc. are the rows in a table. Datasets provide the columns: attributes linked to each entity.
Datasets can come in many formats: tables, vectors, rasters, XML. What distinguishes them from entities is that datasets are not yet organized by entity: the rows don’t refer to the entity yet (and therefore require some linkage algorithm).
For instance, a user might have a dataset of elevation, flood risk, or hurricane wind fields and wants to link it to buildings, a type of entity.
Themes#
Datasets are grouped into themes. The top-level themes are pre-defined, so the data/folder space does not get cluttered. They are:
Theme |
Description |
|---|---|
|
Temperature, precipitation, change |
|
Topography, geology, soils |
|
Land cover (usually remotely sensed) |
|
Rivers, lakes, coasts |
|
Vegetation, species, land cover |
|
Buildings, infrastructure, roads & accessibility |
|
Demographic data (aggregate) |
|
Data of persons, e.g. property owners (sensitive) |
|
Floods, storms, wildfires |
|
Zoning, conservation |
