Documenting Spatial and Temporal Extents
From Earth Science Information Partners (ESIP)
The Extent Spiral defines the spatial and temporal extent of the dataset. This information can be displayed on maps, profiles and timelines and used in spatial and temporal searches. Most documentation dialects include this information because it is so important to data discovery.

Extent information is included in the Attribute Conventions for Data Discovery and ctCDF files as global attributes:
<attribute name="geospatial_lat_max" value="90.0 " type="double"/> <attribute name="geospatial_lat_min" value="-90.0 " type="double"/> <attribute name="geospatial_lat_resolution" value="0.0416 " type="double"/> <attribute name="geospatial_lat_units" value="degrees_north"/> <attribute name="geospatial_lon_max" value="360.0 " type="double"/> <attribute name="geospatial_lon_min" value="0.0 " type="double"/> <attribute name="geospatial_lon_resolution" value="0.0416 " type="double"/> <attribute name="geospatial_lon_units" value="degrees_east"/> <attribute name="geospatial_vertical_max" value="0.0 " type="double"/> <attribute name="geospatial_vertical_min" value="0.0 " type="double"/> <attribute name="geospatial_vertical_positive" value="up"/> <attribute name="geospatial_vertical_units" value="m"/>
Many of the attributes included in this spiral can be calculated from the data using standard netCDF Tools if the file is compliant with the NetCDF Climate and Forecast (CF) Metadata Convention. In ncISO these attributes are given as part of the CFMetadata group:
<group name="CFMetadata">
<attribute name="geospatial_lon_min" value="-180.0" type="float" />

Spatial and Temporal Search
This basic extent information supports spatial/temporal searches that are increasingly important as the number of map based search interfaces increases. Many of the attributes included in this spiral can be calculated from the data if the file is compliant with the NetCDF Climate and Forecast (CF) Metadata Convention. Describes a simple latitude, longitude, vertical and temporal bounding box. For a more detailed geospatial coverage, see the suggested geospatial attributes. Further refinement of the geospatial bounding box can be provided by using these units and resolution attributes. Many of these extent attributes are calculated using the CF-Conventions.| Concept | Description | Dialect (Fit) Paths |
