DASOS released Date: 20/01/2017 This project is funded by the Centre for Digital Entertainement and Plymouth Marine Laboratory and the source code is released under the GNU GENERAL PUBLIC LICENSE, Version 3. For any publications using DASOS, please reference the following paper: Miltiadou M., Warren M. A., Grant M., Brown M., 2015, Alignment of Hyperspectral Imagery and full-waveform LiDAR data for visualisation and classification purposes, ISPRS Archives 36th International Symposium of Remote Sensing of the enviroment Available at: http://meetingorganizer.copernicus.org/ISRSE36/ISRSE36-158-2.pdf For testing the system, please download the following sample here: https://rsg.pml.ac.uk/shared_files/arsf/DASOS/ "These sample data were collected by the NERC Airborne Research and Survey Facility (ARSF). Copyright is held by the UK Natural Environment Research Council (NERC). The data are free for non-commercial use, NERC-ARSF must be acknowledged in any publications, software or other media that make use of these data." Installation Dependancies: qmake-qt4 gmtl library - please make sure that .pro file points to the correct directory -std=c++11 Installation guide: $: qmake-qt4 $: make Instructions on how to use the software: $: ./DASOS --help DASOS User Quide: --------------------- -las <lasFileName> The name/directory of LAS file. The program only supports LAS1.3 with waveform packet format 4. -pw <pulsewavesFileName> loads an a pulsewave file instead of a LAS or an exported volume -volume <volumeFileName> loads an exported volume instead of reading a LAS or pulsewave file -vols <dir loads all the exported volume that are inside the given directory "dir". This option must and only be used for generating 3D priors -vl <voxelLength> The length of the voxels in meters. Default value is 2.5m -nl <noiseLevel> The threshold that separates noise from the actual data in the waveforms.Default value is 25 Please note that the intensity of each wave sample haven't been transformed to GHZ yet. According to the LAS file specifications there is a way to do, but that will be included in future releases of DASOS. -iso <isolevel> The isolevel defines boundaries of the implicit object. By default it's zero. Please note that noise level and isosurface level are related. -userLimits <maxNorthY> <minNorthY> <maxEastX> <minEastX> User define Limits of the area of interest -dtm <dtlFileNameIn_.bil_format> subtract the pre-calculated dtm from each waveform sample before importing it to the volume. Please note that the format should be .bil and it currently only supports float pointing numbers saved into the .bil with potential limitations. -csv <fieldplots.csv> The input csv file that lists all the trees from a number of field-plot. This is a compulsory input for generating 3D priors; -igm <igmFileName> The name/directory of the .igm file that defines the geolocaiton of the hyperspectral pixels. -bil <bilFileName> The name/directory of the .bil file that contains the hyperspectral cube. -fodis <fodisFileName> The name/directory of the .bil file for hyperspectral imagery -obj <objFileName> The name of the .obj file where the polygon representation of the LiDAR file will be exported to. A texture is exported when hyperspectral images are loaded. Please note, that a bug was currently detected into the algorithm and the polygon may look like a bunch of triangle instead. -rgb <band1> <band2> <band3> Defines the 3 bands of the hyperpectral images that will be used for texturing the polygon mesh If not defined the default values 140, 78 and 23 are used. Only used if a bil and igm file are loaded. -map <type> <outputName> The available types are: - NON-EMPTY_VOXELS - DENSITY - THICKNESS - FIRST_PATCH - AVERAGE_HEIGHT_DIFFERENCE - LAST_PATCH - HYPERSPECTRAL_MEAN - NDVI - LOWEST_RETURN - FIELDPLOT - ALL_FW All the maps are exported into .asc format and can be loaded int QGIS and other software packages. The ALL_FW option generates one metrics for each available full-waveform LiDAR related metrics and their names are: outputName+metricsType+.asc -map HYPERSPECTRAL <band> <outputName> The hyperspectral map needs an extra parameter defining which band will be outputed -exportVolume c <volumeFileName> exports the volume into an ASCII file to speed up future interpolation of the data. 'c' refers to compressed and its an implicit functionality. -column <label> the label of the column that defines the class of each entry (e.g. <label>= isDead) -class <className or ALL> the name of the class (e.g. dead or alive) of interest or ALL. If a class is chosen, then only the columns that contain a tree of that class are taken into consideration; a prior is exported for each tree that belongs to this class only. The ALL option is the area of interest and generates a template for each column that lies inside the voxelised space. -ttype square <x> <y> <z> generates a squared prior of size x, y, z voxels. The systems finds the first non empty voxel starting from the top of the column. By default it moves one voxel upwards and sets that to be the top of the prior. It is highly recommended to use odd numbers, otherwise the centre of the prior will be wrongly set and unpredicted output values may occur. -ttype cylinder <h> <r> generates a cylindrical template with height h and diameter (2 × r + 1) voxels and height h. The systems finds the first non empty voxel starting from the top of the column. By default it moves one voxel upwards and sets that to be the top of the prior. -mheight <n> moves the template into the y-axis n voxels upwards instead of one which is the default. The value n must be a positive number. -eparameters <raw or processed> the ‘raw’ option saves all the intensity values of the template and the or processed> ‘processed’ option saves parameters derived from the raw intensities.
