    1818The event file is a comma separated (csv) ASCII text file. This can be viewed in any simple text viewer or in most spreadsheet software (such as MS Excel or OpenOffice). The file contents are described more fully [ here]. The data contained in the file are post-processed navigation and attitude information, and should match up with the information that has been 'tagged' on to the TIFF images. Note that currently we do not have a method for calculating the camera boresight and so this is not included in the attitude values.

    2222The thumbnails are supplied as JPEG images. This is a type of compressed image format that can be opened by most image viewers. The supplied thumbnails include one for each of the full size TIFF photographs. These can be used to quickly scan through the data to search for required images.

     26The photographic data is supplied as full resolution, 16-bit, RGB TIFF images. This is an uncompressed image format that is supported by GIS systems and many image viewers. The images have been 'tagged' with extra fields of information including project meta-data and aircraft position and attitude. The tags can be read using software such as [http://www.sno.phy.queensu.ca/~phil/exiftool/ ExifTool]. The information in the tags is also available in the event file spreadsheet. Note that no geocorrection or othorectification has taken place on the images and they are supplied in the orientation that they were captured.

     30The KML file is a Google Earth format file written in a markup language (similar to XML). This file can be opened and viewed in Google Earth. It displays the location of the aircraft at specific times, location of Eagle and Hawk flight lines (if any were captured) and locations of where the photographs were captured. Clicking on the individual photograph icons should show the corresponding thumbnail image.
