This section covers annotation management (creation, edition, deletion, export, organizing groups) and features for lengths, perimeters, areas, and volume calculations that can be directly obtained from the geospatial data contained in these annotations.
1. Annotation Categories
Available annotation categories are : point, line, polygon, box and a ruler :
2. Creating an Annotation
Select the annotation type you want to create from the left side of the map. All the created annotations will be available under Site Data & Survey Data groups, on the layer management panel :
2.1. Drawing on Map
Select annotation type and draw on map ; double-click the last point of you annotation to finish a polygon or line.
2.2. Edition (3D view only)
Step 1 - Click Edit icon to modify the geometry of the annotation on map :
Step 2 - Select the annotation on the map to open the right side information panel to modify annotation STYLE :
3. Deleting an Annotation
Deleting an annotation is a non-reversible action. Two methods for deletion : from the layer panel, with the drop-down menu in front of annotation, or from annotation information panel :
4. Adding a Description
It is possible to add a description under the annotation. Click in annotation to edit from the information panel :
5. Adding a Tag
It is possible to add one or more tags to an annotation. From the information panel Click on + Add tag :
6. Searching Tagged Annotations
From the main Sites view, enter tag description in Search bar. The search will return the list of projects containing this tag. It can equally be used inside a Site :
7. Polygon Annotation
7.1. Perimeter & Surface Measurement
After completion of the polygon annotation drawing, the resulting polygon area is computed and displayed in the annotation panel.
7.2. Volume Calculation
Read here detailed instructions about volume calculations.
8. Point Annotation
8.1. Reading Coordinates
Coordinates and altitude at a certain location on map can easily be read from the annotation information panel, using a point annotation as in example below :
8.2. Adding Symbols & Markings
Point coordinates can be used to mark permanent, temporary or specific situations using the symbol library. On a point annotation, open the information panel on right side and go to STYLE section, select an icon :
9. Line Annotation
9.1. Distance Measurement
There is two way to measure distance :
- The ruler tool : Write the length close to the drawn line
- The line tool : Write the length of the line in the info panel of the annotation.
9.2. Elevation Profile
It is possible to immediately calculate and display an Elevation Profile along the cross-section defined by a Line annotation. Open Profile section from the information panel ; you may change the DSM if more than one are available :
9.3. Attaching files to a point annotation
This can be notably used to store a close range picture taken from an asset after a field operation, so as to report & archive completed work. After clicking an annotation, go to Attachments section from its information panel :
Then click Upload :
A preview is available in information panel at Attachements section :
10. Organizing your Annotations
Use groups and subgroups features to organize and hierarchize your annotations as you would do with layers :
