Here you can set your origin point, maximum and minimum coordinates, patch size, and whether or not the world “wraps” as a toroid or cylinder. NetLogo has an in-built, gridded topology which can be manipulated by right clicking on the world window in the NetLogo interface and selecting “edit”. these patches are “grass”, other patches are “not grass”). However, for most applications, the spatial data generated by NetLogo models are gross abstractions (e.g. The NetLogo platform possesses several of the basic characteristics of a GIS, in the sense that it keeps track of spatial data in a systematic way, and can be used to create visualizations of spatial data. In this tutorial, I’ll talk about how to do this using NetLogo. If we want to build models that operate in realistic geographic settings (and many archaeological applications of agent-based models are aimed at this goal see here or here for examples), we need to find a way of integrating geographic data with models. For archaeology and other disciplines where the systems under study are cannot be confined to a laboratory, this often means being able to consider our data in spatial terms. This is certainly useful when dealing with a general problem like segregation, but what if we have a specific case study to which we want to apply our model? The integration of models with case-specific datasets becomes particularly important when our models are to be used for policy and decision-making. In these instances, it is often necessary to have models that are capable of producing results that can be interpreted in real-world terms.

If you mention this model in a publication, we ask that you include these citations for the model itself and for the NetLogo software: This model is based on the NetLogo Flocking model. How does adding roads change the pattern of nest infection? CREDITS AND REFERENCES Press the ADD ANOTHER ROAD button to add a second road. HOW TO USE ITĬlick GO to start the parasites. Monitor windows count the number of nests, and the number of infected nests separately. Initil numbers of NESTERS and PARASITES are determined with sliders. Parasites will fly in a random pattern, but tend to stay close to the road. PARASITES are clustered on the edge of the forrest. The NESTERS are radnomly distributed through the forrest. The forrest is bordered by a brown road on each side. The black icons are NESTERS, their nests do not move. The red icons are PARASITES, parasites fly around the edge of the forrest, looking for nearby nests to lay eggs. When cuckoo eggs hatch, the chicks push nestmates out. Cuckoos lay eggs in the nests of other birds. The NEST PARASITES model simulates the ecology of European cuckoo birds. (For example, if you have multiple applets in differentĭirectories on the same web server, you may want to putĪ single copy of the NetLogoLite files in one central place andĬhange the archive= lines of all the HTML files to point In the HTML code to point to their actual locations. If the NetLogoLite files and your model are in differentĭirectories, you must modify the archive= and value= lines and ending with, and paste it into any HTMLįile you want. If you want, you can just take the HTML code beginning with You don't need to include everything in this file in your page. Though, so if it doesn't work from your hard drive, please try On some systems, you can test the applet locally on your computerīefore uploading it to a web server.
