Multivista UAV Mapping is a service and associated cloud-based deliverable that provides enhanced 2D and 3D, visual and spatial datasets derived from aerial photos captured with an Unmanned Aerial Vehicle (UAV). Multivista's UAV Pilot-In-Command fly a programmed route over the customer's site capturing large numbers (ranging from several hundred to a few thousand) of nadir and oblique photos of the area of interest - typically the entire construction site. The information from the collection of images are combined together using a technique known as 'photogrammetry' to yield a variety of output formats including orthomosiac maps and 3D elevation models. Multivista has partnered with DroneDeploy, the leading drone software platform, to perform the cloud-based photogrammetry processing.
The Multivista UAV Mapping service offers the following deliverables through the MDS:
A geo-referenced, 2D orthomosiac map image shown against a satellite or street base map. Orthomosiac resolution can be as high as X pixels per inch. Orthomosiac information can include either Imagery, Elevation Heat Maps, or Plant Health Maps
A 3D model shown through a viewer that enables the user to pan, rotate and zoom a colored 3D rendering of the site
The 2D orthomosiac viewer supports the following features and workflows:
Selection of which map set to view by date
The ability to select from an Orthomosiac, Elevation or Plant Health mapping layer and vary the opacity of the layer
The ability to select a Satellite, Street, or Hybrid base map layer
The ability to toggle on/off elevation Contour Lines with selectable color, line style, interval and opacity
Various annotation and measurement tools including:
- Location annotations which indicate local Elevation, Slope, Latitude and Longitude
- Distance annotations which indicate Distance along a line, End Point Latitude and Longitude and a visual representation of the Elevation Profile of the selected line
- Multi-Point distance annotations which indicates segment and total Distances along a series of line segments
- Area annotations that show the Perimeter and projected Area of a given polygon area
- Volume measurements that show the Perimeter, projected Area, Cut Volume and Fill Volume of a given area
- All annotations support the following features and attributes: The ability set title, color, visibility and sharing permissionsImperial or metric units
- Creating a copy of the given annotation on the current map
-The ability to import / export annotations between map dates
Generate a PDF report showing the map, and selected annotations and summary information
Create a screen capture of a portion of the map for use in Multivista photo workflows such as annotating, commenting, saving to computer or albums or exporting to integration partners
Create exports for download of varying map projections and resolutions in following formats:
- 3D Model: OBJ
- Elevation Model: GeoTIFF, JPG, Raw Elevation Values (DEM), Shapefile, Contour DXF (Autocad), Contour SHP (Shapefile)
- Plant Health Model: GeoTIFF, JPG, Shapefile
- Orthomosiac: GeoTIFF, JPG
- Point Cloud: LAS, XYZ
