9 Mapping Heritage Economics for Spatial Analysis in Historic City Cores Christian Ost Professor in Economics, ICHEC Brussels Management School (Belgium)
The identification of economic values in historic city cores, and their measurement with the use of indicators, aims to provide the basic material for a mapping process. Availability of reliable data makes the identification of statistical units to measure economic values a key element in the mapping process. The identification of thematic maps is related to the definition of economic values, and this chapter identifies tentative thematic maps belonging to several categories of values: non-use values, use values related to the real estate market, use values related to cultural tourism, and use values related to impacts on local economy. Showcasing the geographic information provided by economic values on maps requires the identification of patterns, connections, and relationships between indicators of all categories of values. This process is two-fold: first, the analysis of indicators related to categories of values; second, the analysis of aggregated values to summarize and map the information. Mapping of selected key indicators describes the relationship between public intervention and economic values. Finally, an economic landscape map is made of compounded values measured for an entire area. Successive layers of values have been laid on top of each other, the first layer being a base map. The final product visualizes the economic landscape of the city. A detailed case study on Mali is presented to apply the concepts described in the chapter.
