“…The third category includes intelligent methods that integrate land cover data in the population estimation, ranging from a simple binary dasymetric method (Fisher & Langford, 1996;Flowerdew & Green, 1989;Holt, Lo, & Hodler, 2004) to more sophisticated procedures such as those that are logical extensions of Wright's (1936) original dasymetric mapping (see Eicher & Brewer, 2001;Langford, 2006;Mennis, 2003;Mennis & Hultgren, 2006;Reibel & Agrawal, 2007) and various forms of statistical analysis (Cromley, Hanink, & Bentley, 2012;Langford, Maguire, & Unwin, 1991;Lin, Cromley, & Zhang, 2011;Lo, 2008;Schroeder and Van Riper, 2013;Yuan, Smith, & Limp, 1997). An alternative approach in this category did not use the land cover categories as the correlate but instead integrated an impervious surface fraction derived from Thematic Mapper (TM) imagery into a cokriging method to interpolate population density using the spatial correlation and crosscorrelation between population and this fraction (Wu & Murray, 2005).…”
