Different ontologies: land change science and health research

Joseph P Messina, William K Pan
2013 Current Opinion in Environmental Sustainability  
Land use and land cover (LULC) is now recognized as an important driver of disease.  ...  Ontological differences embedded within disciplinary structures impede progress limiting the ultimate potential of both LULC data and land change theory within disease research.  ...  Despite this, within the broader health community, land surface models do play an increasingly important role for helping explain disease causation.  ...

Projection of Land Use Change Patterns using Kernel Logistic Regression

Bo Wu, Bo Huang, Tung Fung
2009 Photogrammetric Engineering and Remote Sensing  
A feature vectors selection method for the KLR model has therefore been proposed to impose sparsity and control complexity.  ...  To test the effectiveness of KLR, a case study was implemented to model rural-urban land-use conversion in the city of Calgary, Canada during the periods 1985 to 1990 and 1990 to 1999.  ...  Since the purpose of this study is to examine the problems that occur when KLR is used for modeling land-use change, only land-use change from nonbuilt-up land to built-up land was considered.  ...
