VLSM: Vector-based Landscape Metrics

Most common landscape metrics are calculated on a raster-basis. However, sometimes landscape information come along in vector-formats. For the calculation of landscape metrics, one must perform a vector-to-raster-transformation often resulting in a lost of information. In VLSM we implemented the following landscape metrics based on vector data:

• Effective Mesh Size based on Moser et al. 2007
• Urban Sprawl based on Ackermann et al. 2013
• Integration Index based on Meinel & Winkler 2002
• Shape Indices based on Forman & Godron 1986
• Edge Length based on Walz 2013
• Shannon's Diversity Index for landscapes based on McGarigal et al. 1995

How to use the functions in R, please refer to the vignette-R. You may also want use the functions in the open-source desktop GIS QGIS. For this, please refer to the vignette-QGIS.
