| 41 | | If there is a marker attached to feature then it is used (over-rides all) |
| 42 | | If not then it checks if there's a marker for it's feature_class |
| 43 | | If so, it uses it |

| | 40 | === Features, Feature Classes & Feature Groups === |
| | 41 | ==== Features==== |
| | 42 | * A Feature is a record in the gis_location table. |
| | 43 | * This can be a point (Lat/Lon), Line or Polygon (WKT) |
| | 44 | * This can be referenced from other tables such as: |
| | 45 | * /pr/person/presence |
| | 46 | * If there is a marker assigned directly to a Feature then that is how the Feature will show up on the map. |
| | 47 | ==== Feature Classes==== |
| | 48 | * A Feature Class is a record in this gis_feature_class table |
| | 49 | * It is a collection of Features of the same type |
| | 50 | * Share a comon Marker (unless over-ridden at the Feature level) |
| | 51 | * If no marker defined then the system default marker is used |
| | 52 | * Can be grouped together into Feature Groups |
| | 53 | * Link to a common resource for URLs & extra fields to pull into Map popups |
| | 54 | ==== Feature Groups==== |
| | 55 | * A Feature Class is a record in this gis_feature_class table |
| | 56 | * This is used to provide Layers on the Map & Feeds for export/view by other systems |
| | 57 | * It is a collection of Features & Feature Groups |
| | 58 | * The default settings start with a Feature Group being created for each Feature Class |
| | 59 | |
| | 60 | === Symbology sets === |
| | 61 | * Symbology sets can be used to provide a set of Icons for Feature Classes based on deployment requirements, e.g. US FEMA |
