UAV mapping delivers the 3D data that design teams need, at a fraction of the cost of traditional surveying. With design work invariably being performed using specialty software on dedicated workstations, Multivista allow for the export of a variety of industry standard file formats to support VDC engineers in their offline workflows. We offer many file types to export including:

JPG
(RGB Image)
Available for all 2D layers: 2D Map, Elevation, and Plant Health.
Includes a .KML file and a .TWF file with the georeferenced metadata.
Easy to share through any standard image software such as Windows Photo Viewer or Preview. Print or use within presentations.

GeoTIFF
(RGB Image)
Available for all 2D layers: 2D Map, Elevation, and Plant Health.
Includes a .TWF file with the georeferenced metadata.
Includes a .KML file is when using the Web Mercator Projection.
File format suited for 2D analysis in GIS software such as ArcGIS or QGIS.

GeoTIFF
(Raw Elevation Values - DEM)
Available for Elevation exports.
One-band GeoTIFF file with embedded elevation values.
File format suited for 2D analysis in GIS software such as ArcGIS or QGIS.

DXF/SHP
(Contour files)
Available for Elevation exports.
Georeferenced lines of equal elevation according to the chosen interval. See Contours.
For use in AutoDesk suite and Mining/Construction software.

Shapefile
(Contour files)
Available for Plant Health exports.
Plant health data stored as a set of shapes (polygons) with a default resolution of 10m x 10m. See Shapefile Exports.

OBJ
(3D Model)
Digital Model. .obj surface with .jpg texture files model.
Not georeferenced: defined in a model-local coordinate system.

LAS
(Point Cloud)
.las point cloud.
Can be used in AutoCAD, ArcGIS, Global Mapper, Applied Imagery, or similar software.

XYZ
(Point Cloud)
.xyz point cloud that contains RGB information (XYZRGB). Resolution is specifiable.
Most common file format accepted across Construction/Mining software formats.

Customizing Exports

For layers that have in-browser tools, such as the 2D, Elevation, and Plant Health maps, you have the ability to customize the exports according to your specifications. The custom exports allow you to:

  • Reduce map resolution
  • Specify a different map coordinate/projection system
  • Manipulate the data (i.e., contour interval the map)


Resolution
Based on your account settings, you can export the maps at different resolution levels. The higher the resolution, the longer the export email will take and the larger the final download. If you are concerned about final file size or processing/download time, reduce the resolution to 50cm/pixel.

Map Projection
One can choose to export maps/models using different coordinate systems or map projections. These projections determine how your data is "projected" from the 3D earth to a flat surface.

World Geodetic System, WGS84 (EPSG: 4326): The most common coordinate system and the standard for all satellite navigation system. It is useful if your third-party software is expecting Latitude/Longitude and Elevation in meters.

Web Mercator (EPSG: 3857): This coordinate system is used by Google Earth, MapBox, Bing Maps, etc. It represents coordinates in meters from Earth's center, rather than Latitude/Longitudes. If you want to import your images into Google Earth or another web viewer, use this setting. When exporting in this setting, you will also receive the .KML file to view your data in Google Earth.

Custom Projection Systems: This allows users to export the maps using other EPSG codes for almost any projection. Check on the Spatial Reference Organization's website to learn more about the EPSG codes.

Image type
Single Image is selected by default, this box is checked, and it will ensure you receive one image for the entire map. If you are concerned the map will be too large to process as a single image on your computer, please check the "Tiled" box, and you will receive the data as a set of tiles. That way, you can load the tiles selectively in a way that is manageable for your setup.
