Multispectral cameras are quickly becoming a valuable tool in drone imagery collection as the cameras become less expensive and lighter. They can be useful for many types of analysis. In ArcGIS Drone2Map, multispectral cameras can be used to assess vegetation health within an area by turning the multiple bands they collect into an orthomosaic to derive various vegetation indices. ArcGIS Drone2Map currently supports processing of multispectral imagery from the following cameras and will continue to expand support for new cameras in the future.
Note:
Multispectral and thermal processing in ArcGIS Drone2Map is only for 2D products.

* Sensors that support radiometric calibration can only be color balanced when using the Digital Number quantity type in the Radiometric Calibration window. Once a value for Digital Number is specified, the Color Balancing check box is available in the image collection processing options.
SlantRange cameras write images that are named using UNIX time stamps. These images have no attached metadata and, even with a GPS file, do not properly import into ArcGIS Drone2Map. However, the SlantRange software can convert the original images into new .tif files that are named properly and contain the necessary flight metadata.
