Steffen Bittner investigates in his Ph.D. how to construct computational models of reality in a cadastre. Reality in a cadastre is a part of social reality. It is highly determined by laws and institutional concepts. An agent based approach is used as conceptual framework for the computational model. The correctness of the model is verified with respect to the reality it represents by agent based simulatuion of typical processes determining reality in a cadastre.
Pricing is a critical element of marketing geographic data.
A high price is a barrier to access the data and prevents the widespread use of the data. A low price will not cover the high costs of collecting and maintaining the data and will not provide the expected rate of return on the investment. To set an optimal price for geographic data is a very difficult issue. Geographic data has particular properties in comparison with other information products on the market. It is not a physical good, and can be exchanged, used, and combined many times without wear.
