News:  Version 1.3 (12/2018): changelog.

AnisView is an educational software to visualize the Bidirectional Reflectance Distribution Function (BRDF) using one of the two radiative transfer models RPV and MRPV.  AnisView has the following features:

Graphic display modes:

  • Geometry: an interactive mode to visualize the user-driven illumination and observation geometry.
  • Single BRF value: BRF as a function of the selected geometry and BRDF model parameters.
  • 2-D plot: a cross-cut or plane along a specified azimuthal direction.
  • 2-D contour plot: circular view of the BRDF field including interactive readout of BRF values.
  • 3-D rectangular/polar plot: 3-D visualization of the BRDF field.

Other features:

  • the BRDF-model settings and the graphic display can be saved in a variety of formats.
  • overlay of observation zenith angles for the sensors ATSR, AVHRR, MODIS, MISR, SPECTRA.
  • isotropic and lambert settings 


Using AnisView requires accepting the AnisView End User Licence Agreement: EULA
AnisView is available for the following operating systems (please use right-click - Save as and download the installer to a local directory). First download and read the AnisView installation instructions. They contain important additional information to ensure a correct installation and functioning of the application.

The installation requires no administrator rights. It will extract the entire package, including documenation, manual, disclaimer and the source code, into a single directory.  After the installation, the extracted directory AnisView can be copied/moved to a different location or device, e.g., an external USB-flashdrive.  In this case, please use the included launcher to start AnisView from its new location.
