geographicElement (choose one) |
0..* | Geographic extent of the resource. At a minimum, provide the GeographicBoundingBox, because most discovery systems rely on this section for spatial searches. Not required when resource is non-geospatial and the scopeCode = 'nonGeographicDataset'. | |
| 3 |
temporalElement (choose one) |
0..* | Temporal extent of the resource. Describe the time period covered by the content of the resource or the date and time range when the data was collected. The use of multiple temporal extents should be explained in the attribute description of the extent. If the resource has a status of 'ongoing' then use the indeterminatePosition attribute without an end date value. Example: <gml:endPosition indeterminatePosition="now"/> | |
| 4 | verticalElement | 0..* | Minimum and maximum vertical extent of the resource. | |
