MSPA Summary Sheet
Title: Morphological Spatial Pattern Analysis of the conterminous US
Abstract: Six data layers, all created using GUIDOS 1.3 MSPA software to identify green
infrastructure components (e.g. core, edge, corridor, etc.). Water was treated three different
ways: 1) as foreground, 2) as background, and 3) as missing using both NLCD 2001 and 2006
for six total layers.
Organization or location where data will be published: Online by NatureServe.
Article(s) for which data were generated: Wickham, J.D., Riitters, K.H., Wade, T.G., Vogt, P.
2010. A national assessment of green infrastructure and change for the conterminous United
States using morphological image processing. Landscape and Urban Planning 94, 186-195.
Clearance history: These data sets and the methods used to develop them were internally and
externally reviewed during the clearance process for the journal articles.
Location where data are maintained: D:\mspa, non-networked workstation in E479, RTP.
