| Abstract: | Accurately representing geographic space in a digital environment continues to confound and challenge researchers. Carrying
out spatial analysis in a setting where geographic representation is subject to change poses problems to be addressed. In
this paper we examine spatial representation in the context of coverage-based location modeling. A geographic region can be
represented in a variety of ways. We present an evaluation of spatial representation in the location of facilities that provide
coverage oriented services. The analysis shows that the modeling results are sensitive to how spatial demand for service is
represented in a digital environment. We develop an approach for evaluating representational appropriateness. This research
contributes to spatial analysis integrated in geographic information system environment.
