How to add/select the acquired image data ?

  • Updated

Once the ROI and GCP info has been checked, you continue by locating the folder containing the image data.

Before you select the folder, double-check whether the file naming conventions have been followed and possible duplicate filename issues handled.

Use the “Select Image folder” button and browse through the folders to locate the image folder in the window that pops up, do not select images in the folder!

Use the “Select folder” button to start the actual loading of the data set. Note that for large missions, this may take a few minutes.

When the image data has been loaded, the number of images is displayed on the screen and the image names are listed along with their positions, provided that position information could also be loaded.

In that case, you also get a visualization of all image locations by orange dots, this means no image is selected yet for processing. This is also indicated in the table containing the list of images, where the header row gives you the number of images to be processed, i.e. 2/194. Note that the ‘970 image files’ are because this is an example of a multi-spectral mission, i.e. at each location 5 images are taken, 1 for each spectral band.

A first estimate of the actual flying height (referenced to ground) is given (based on the Exif data).

In the case where the position info is not included in the image metadata (orange dots are not displayed), or if the user wants to override it, the option is given to upload a file, containing the position data. This is explained in the Field Software user manual (section 'Uploading image position data files').

The location of the calibration images is visualized by blue dots and an indication is given for the first and last image of the flight.

Once the image data has been properly loaded, you can continue to verify the quality of the individual images.
