* Probability of effectiveness: uniform distribution. \({}^{\star}\) Probability of cost value: uniform distribution in units of currency. The cost of UAVs, Base stations, and Registration databases are neglected in our calculations per physical object. Due to the high cost values of airborne data sources, they must be budgeted separately. + Probability of timing value: uniform distribution in units of seconds. \({}^{\star}\) These values depend on day or night time, and on holiday periods. \(\&\) Largely dependent on weather conditions.

Table 11: The Estimated Parameters of a Selected Set of Relevant Data Sources
## Appendix A Data Sources Attached to Physical Objects

Table 10 is used to document the estimated characteristics of data sources that can be attached to physical objects. The definitions of the columns and rows are similar to the ones of Table 11.

## Appendix B Estimated Parameters of the Effectiveness of Fusion of Multiple Sources

Table 12 is used to document the estimated characteristics of the mutual effects of data sources to each other in case of data fusion. The first column and row list the considered data sources. The first row refers to the data sources symbolically, expressed as (a) to (n). These symbols refer to the data sources listed in the first column. For example, (a) refers to UAV cameras. The number \"0\" in a cell indicates that there is no contribution of the related data sources to each other. The values \"1\" and \"2\" indicate weak and strong contributions, respectively. For brevity, medium contribution values are not shown. The semantic meanings of the degree of contributions are defined by the formulas in Section 6.2. ## References
