Abstract: This paper evaluates indicators to analyse mixed activities, representing a combination of various facilities and services, in urban areas. Although mixed activities play an important role in urban planning projects, measuring themhas been problematic due to the lack of appropriate data and measurement approaches. In ecology, there are dozens of potential diversity indices, which have been deployed in recent land use studies to measure mixed activities. However, ecologists have highlighted that these indices are not always expressed inintuitive units. Recognizing the limitation of commonly used diversity indices, Hill numbers, which represent a mathematically unified family of diversity indices, are used. Taking advantage of new data sources such as Points of Interest (POIs) from OpenStreetMap, this study applied Hill numbers on POIs to measure mixed activities at a quarter level in Frankfurt. Results showed that Hill1 (exponential of Shannon) is an appropriate quantitative measure to describe the diversity of facilities and services by a single numerical value. However, it is difficult to explain which factor, namely evenness or richness,has a stronger impact on the index. To gain a more comprehensive picture of mixed activities we suggest to considering further indicators such as evenness and richness.

GI_Forum publishes high quality original research across the transdisciplinary field of Geographic Information Science (GIScience). The journal provides a platform for dialogue among GI-Scientists and educators, technologists and critical thinkers in an ongoing effort to advance the field and ultimately contribute to the creation of an informed GISociety. Submissions concentrate on innovation in education, science, methodology and technologies in the spatial domain and their role towards a more just, ethical and sustainable science and society. GI_Forum implements the policy of open access publication after a double-blind peer review process through a highly international team of seasoned scientists for quality assurance. Special emphasis is put on actively supporting young scientists through formative reviews of their submissions. Only English language contributions are published.
