Critical GIS : theorizing an emerging science

Two contemporary research questions in GIS are investigated, as a means of establishing a preliminary methodology for critique that engages with GIS at a conceptual, as well as a technical level.  ...  This research takes as its starting point the past decade of critiques from human geographers, and proposes an alternate model for appraisals of technology.  ...  Conservation Service) maintains a network of county outreach offices.  ...
