Color Code
When the Geolocation B.I. is selected, the following colors are applied to the objects in the tree and in the 3D area:
| Color | Signification | Description |
|---|---|---|
|
Defined | The element is assigned an active geolocation extension and the geolocation is enabled for its direct father product. |
|
Computed | One of the parent elements is geolocated (blue status): geolocation for the element can be retrieved from its parent product (s). |
|
Inactive | The element is assigned a geolocation extension but it is not taken into account for positioning purposes in the scene. |
 |
Not Defined | The element is not assigned any geolocation extension. |
 | Reference issue | The Cartesian Coordinate Reference System, abbreviated CRS is deprecated or missing in the dialog box. |
 | Discontinuous | Geolocation is enabled for the element but one of its parent products is not geolocated. |
 | Deviant | There are two different CRS in the root path to the selected element. |
Label
When the Geolocation B.I. is selected and you select an object in the 3D area, a label is displayed that contains detailed information:
| Attribute | Description |
|---|---|
| XXX_object_identifier for example Site0000121 | Object name with a unique identifier |
| Defined Geolocation* | Geolocation is defined on this product, clicking removes geolocation. |
| Edit Geolocation | Lets you open the Geolocation panel. |
| Computed Geolocation | The upper element in the product structure is accounted for in the calculation. Clicking adds geolocation information from the current position and launches the Geolocation panel. |
| Inactive Geolocation* | Geolocation is defined but not enabled. Clicking enables geolocation. You can activate ( ) or remove it ( ). |
| Not defined Geolocation | Geolocation is not defined for the product. Clicking adds geolocation that is assigned to children provided that they are geolocated or at the origin of the Coordinate Reference System (abbreviated as CRS). |
| Deprecated Coordinate Reference System* | The currently used CRS is deprecated and should no longer be used. |
| Coordinate Reference System not found* | The current used CRS is missing. |
| Discontinuous Geolocation | Position of the product cannot be computed because geolocation is missing on an upper element within the product structure. Clicking removes geolocation. |
| Deviant Geolocation | Position cannot be computed because an upper element within the product structure is using a different CRS. |
Notes:
- Although geolocation is stored as an extension of the reference objet, the status of geolocation displayed in the tree is contextual: all statuses are computed with respect to the current product structure opened in session.
- *In the above described situations, you can edit geolocation parameters.
Examples
Let's consider the following cases:
- Case 1: Create a terrain and click Geolocation B.I.
. The B.I. status is
set to Defined. By default, terrains are created with geolocation
extensions. Create a site product, and remove geolocation assigned to it.
Insert the terrain you have just created under the site product. The B.I. status for the terrain
turns to Discontinuous. - Case 2: Create a site with CRS WGS84 (EPSG:4326) for example, change the CRS to EGM2008 geoid height (EPSG:3855). Create a terrain geolocated in that CRS, and insert it below the previously created site product. The B.I. status for the site is Defined and Deviant for the terrain.
- Case 3 is continuation of case 2: After having inserted the terrain below the site, deactivate geolocation for the terrain product. Although the B.I. status for the terrain remains Deviant, the site status is Defined.
- Case 4: Create a terrain, remove geolocation, and launch B.I..The terrain is Not Defined. Insert it under a geolocated site, its status changes to Computed.
