    2020'''''' will set up a PhotoScan project and align photographs. If Ground Control Points (GCPs) are available, then the script will stop and prompt you to manually locate them in the PhotoScan project. If no GCPs are available, the script will complete the whole PhotoScan processing workflow without (obviously accuracy of data is significantly reduced). This step is not automated. '''''' is run after the and placement of Ground Control Points.[[BR]]
    2122'''Ground Control Points'''[[BR]]
    2223Coordinates of GCPs in CSV format can be added to PhotoScan (or input manually). The user will then need to 'drag and drop' the marker locations to their locations visible in the photographs input. This needs to be done for '''all''' photographs each GCP is visible in.[[BR]]
    2324Note: once a couple of GCPs have been located in multiple respective photographs; the 'reproject' button (looks like a recycling symbol) will automatically place the remaining photo. These will still need to be accurately places, but will save a lot of time nevertheless.[[BR]]
