dataset
posted on 2020-07-03, 16:57 authored by Ashkan GholamialamAshkan GholamialamThis network dataset is created to investigate wetland connectivity using a multi-criteria optimization approach. Three arc attributes represent cost associated with movement on the landscape. The digital elevation model is used to compute the topographic wetness index and cost related to elevation change. The landuse/landcover layer is basis for calculating likelihood of successful traversal. The input geographic information layers are available here: http://msdis.missouri.edu/
The built network consists of 12 wetlands serving as origin and destination, and 1277 network arcs. For each arc there are several arc attributes as described below:
ID1: reference to arc endpoint at the lower altitude
ID2: reference to arc endpoint at the higher altitude
DEM1: elevation at endpoint 1
DEM2: elevation at endpoint 2
DEMc: elevation at midpoint of arc
TWI1: topographic wetness index at endpoint 1
TWI2: topographic wetness index at endpoint 2
TWIc: topographic wetness index at midpoint of arc
LUL1: landuse/landcover type at endpoint 1
LUL2: landuse/landcover type at endpoint 2
LULc: landuse/landcover type at midpoint of arc
LULb: base successful traversal likelihood associated with each landuse/landcover type
LULf: final value of successful traversal likelihood (considering arc length)
DIST: arc length in meters
