http://www.innovativegis.com/basis/Default_files/image002.jpgBeyond Mapping Compilation Series

   

by Joseph K. Berry

 

…Beyond Mapping columns appearing in GeoWorld (formally GIS World) magazine

    from March 1989 through December 2013.

 

 

Most GIS applications have focused on mapping and spatial data management for viewing and geo-query of mapped data.  Map analysis and GIS modeling involve entirely new spatial reasoning concepts and procedures that are not reflected in our paper map legacy.  The four books in the Beyond Mapping Compilation Series are based on Joe Berry’s popular "Beyond Mapping" columns in GIS World/GeoWorld magazine that discusses the new breed of map analysis tools, how they can be used to better characterize and communicate spatial relationships, be organized into effective GIS model solutions, and spark entirely new spatial paradigms. The topics covered are written for novices, as well as GIS professionals, in a witty style that entertains as well as informs.
