The default is to use the value in the project file if found. Should the returned network be simplified as much as possible and saved? The values specifies the name of the file which the data are to be stored.

I adapted cities2. Exe will prompt the user with three questions: one can set a threshold in terms of a minimal percentage of the total set of city-names in the data or set a minimum number of occurrences. Both these options enable the user to limit the size of the network. The third question enables the user to obtain additionally the cosine-normalized data matrix. This is not advised for large matrices because of adding to the computation time. The fourth option in cities1.

The output of the geo-coding can be used as input into Cities2. Exe after saving the file as a DOS text file. The program prompts for the name of this file. It produces a number of ouput files in various formats:. These files can also be edited. In Google Maps, one may prefer cities2. Change the following parameters:. The resulting file contains both the nodes and the links. It may take the browser some time to load it.

If IE gives an error message, try Firefox. Networked nodes are default in red, not-connected ones in orange. One can save the file as. We used the World Coast Line data designed to a scale of ,, for this purpose. The files can be edited and adapted to specific usages. The value of the links is equal to the co-occurrence value, but the main diagonal values co-occurrences within the same city are not considered.

In other words, only the lower triangle of the co-occurrence matrix is used. In the. Further processing in Pajek ad 4.
