Project Data makes up the building blocks of the Virtual Surveyor app and includes all the different types of data that are used and created in the software.
Project Data is listed and grouped by layers in the Project View where they can be selected. Most Project Data is displayed in the Viewport from where they can also be selected (except Terrain Modifier and Terrain Offset).
Every created piece of project data has a descriptor and optionally a number that can be updated in the Structure group of the Home tab.
The list below gives an overview of the different types of data that are available within the Virtual Surveyor app:
| Icon | Project Data | Description |
|---|---|---|
 | Point | A geometry that has a location in geographic space, but that has no extent. A point is represented through a symbol, color, and size. You draw points to describe the topography at bare-earth or to capture specific features like a manhole. |
 | Multi-point | A set of Points. A piece of data that is labeled as Multi-point is typically created through a grid operation like Q-Points or Low-pass points. Multi-points allow you to easily manage large sets of points as a single piece of data. |
 | Polyline | A geometry that consists of line segments that connect a series of geographic coordinates. A polyline is displayed with a color and a width. You draw breaklines to capture sudden changes in slopes like banks in quarries, road embankments, etc. |
 | Boundary | A geometry that is a closed polyline. A boundary is displayed with a color and a width and doesn't have a fill. A boundary confines a work area and is used as input in many operations like gridding, triangulation, stockpile calculation, cut/fill analysis, terrain export, etc. |
 | Surface | A set of triangles that are used to describe a topography. Surfaces are displayed as triangles or contour lines and can contain voids. Surfaces are used as input for a terrain modification, or as a deliverable for your customer. |
 | Profile | A line geometry that follows the Elevation Terrain exactly. A profile line appears in the 2D Profile View as a graph with elevations plotted along the line geometry. The Profile line also appears in the Viewport where it is draped on the terrain. |
 | Stockpile | Represents a certain quantity of material and can be presented as a volume, tonnage, and/or a monetary value. It has a single color that is linked to a material type. Stockpiles can be exported as a stockpile report in PDF format or as a text file. |
 | Cut/Fill | Displays the elevation differences between two elevation models (terrain and/or surface) through a color representation and/or spot heights. A Cut and Fill also displays the volume difference between the 2 elevation models split into a cut and a fill quantity. |
 | Image Terrain | Typically the orthomosaic from your drone photogrammetry. Image Terrains can also be a topographic map (thematic colors) or cadastral map (black/white colors). Image Terrains are draped over the Elevation Terrain. |
 | Elevation Terrain | The DSM (or DTM) from your drone photogrammetry. Also, point cloud files from LiDAR drones are converted to Elevation Terrains. The Elevation Terrain is shown as a hillshade or augmented with the imaged terrain or other terrain lenses. |
 | Water | A plane at a certain elevation that is used to represent water. Water can be clipped or intersected with the terrain. You can use Water to calculate the fill volume for basins or remove noise over water bodies. |
 | Modify Terrain | A Terrain Modifier is created via an input surface, or one of the cleaning tools and dynamically modifies and changes the Elevation Terrain. You typically use a Terrain Modifier to remove machines and conveyors before calculating a volume difference between two terrains. |
 | Offset Within (Terrain offset) | A Terrain Offset is created from an input boundary and changes the elevation with a certain value. The Terrain Offset is typically used when you have ellipsoidal elevation while you need mean sea level or a local elevation datum. |
 | Position | A viewing position from which you observe your drone data. You typically find yourself at a certain geographic position, viewing the terrain at a certain angle with respect to the horizon and north. |
 | Measurement | Captures the specific characteristics of a certain part of your topography. A measurement tool is used to show the height of banks or structures or the steepness of slopes. |
