In order to add, or upload the Radiometric Calibration images, first you need to capture the Radiometric Calibration images. To understand how to perform Radiometric Calibration, refer “How to Capture Radiometric Calibration Images”.


To add the Radiometric Calibration images along with the survey images, follow these steps.


Note: Screenshots included in this article are of the PrecisionViewer tool.
The procedure of uploading Radiometric Calibration images remains the same even if you are using PrecisionMapper web-based application.


 

1. While choosing survey images, make sure that you do not select the Calibration Images (Figure 1).

Figure 1: Calibration Images



2. In Camera Parameters, click Radiometric Calibration button (Figure 2).

3. Click Browse button, and select appropriate radiometric Calibration target images for each multispectral band (Figure 3).


Figure 3: Browsing for Radiometric calibration images




Note: You are supposed to upload at least one radiometric calibration image for each band of the multispectral sensor.
You can upload more than one radiometric calibration image for each band to improve the overall accuracy of your survey output.
Make sure that you upload same number of images for each band.

Call-outs 
Description
1 Radiometric calibration images captured in Blue band.
2 Radiometric calibration images captured in Green band.
3 Radiometric calibration images captured in Red band.
4 Radiometric calibration images captured in NIR (Near Infrared) band.
5 Radiometric calibration images captured in Blue band.



4. Once radiometric calibration target images are uploaded, click Save (Figure 5).
