DART were granted a series of airborne surveys by NERC ARSF. These surveys comprised EAGLE and HAWK hyperspectral data, LiDAR and visible wavelength photography. The surveys were flown at specific periods during the crop cycle in order to evaluate the impact of the phenological cycle on heritage detection.

Survey dates were: 2011-06-14 (Diddington only), 2012-03-23 and 2012-06-20. This dataset is the visible wavelength photography. These were captured using a Leica RCD105 survey camera. The dataset comprises the images as 16 bit TIFs (Tagged Image File Format), an event file containing the EO(Exterior Orientation) parameters, camera calibration certificates containing the IO(Interior Orientation) parameters, thumbnails in JPG (Joint Photographic Expert Group) format, and Google Earth kml files showing camera positions.

Use of these coefficients, particularly the radial distortion coefficients, in other photogrammetry software may require changing the sign of the coefficients. Interior orientation parameters below are determined using the Australis software package and reflect a static (i.e., laboratory) calibration. The parameters given reflect the so-called “balanced lens distortion” model.

resource.descriptionNear vertical digital photographs were acquired by NERC ARSF using the Leica RCD105 digital camera as part of the airborne surveys conducted for the DART project. The data are supplied as 16-bit TIFF images with additional meta-data in TIFF tags. Where possible, the TIFF tags comply with the TIFF and EXIF standards used for digital cameras. The standard geolocation tags have been added so that the photographs will appear in the right world position correctly in album software. Note this is not the same as orthorectification or full georeferencing this merely locates where in the world the photographs were taken. Some additional information has been placed in XML in the ImageDescription tag (see below for an example). This includes: -Original Filename - raw camera filename that the photograph was produced from -Project Code - ARSF Project Code -Flight Day - Julian Day of Flight -Location Name - Site Location -Position Information -Latitude - latitude of aircraft when image taken -Longitude - longitude of aircraft when image taken -Height - height of aircraft when image taken -Exterior Angles -Omega - rotation about x-axis -Phi - rotation about y-axis -Kappa - rotation about z-axis The tags can be read using free software such as exiftool, available from: http://www.sno.phy.queensu.ca/∼phil/exiftool/, freeware, Windows/Mac/Linux. The event file gives you an overview of the time, location and attitude of the aircraft when each photograph was acquired. This should agree exactly with the data in the tagged tiffs, since both data are from the post processed navigation file (unless mentioned otherwise above). The eventfile is in Comma Separated Value (CSV) format and can be viewed using any text editor or as a spreadsheet in Excel / OpenOffice. There are 17 columns in the event file, the relevant ones are: -ImageName: The filename of the photograph in question -GPSTime: The time when the photograph was acquired -Latitude: Latitude when the photograph was acquired -Longitude: Longitude when the photograph was acquired -Altitude: Altitude when the photograph was acquired -Omega: Rotation about the x-axis -Phi: Rotation about the y-axis -Kappa: Rotation about the z-axis . This fiel is the documentation Read_Me*.pdf contains information specific to each flight /doc Contains the calibration data for the sensor as pdfs /eventfile contains a csv indicating the exterior orientation parameters for each frame
