GIS Gradient Example provides another example of how to use the GIS extension. See the other GIS code example, GIS Gradient Example, for an example of this technique. This model doesn't do anything particularly interesting, but you can easily copy some of the code from the Code tab into a new model that uses your own data, or does something interesting with the included data. For example, you could modify highlight-large-cities to highlight small cities instead, by replacing gis:find-greater-than with gis:find-less-than. Most of the commands in the Code tab can be easily modified to display slightly different information. See the code tab for specific information about how the different buttons work. You can then use all other features of the mode. Select a map projection from the projection menu, then click the setup button. The planets revolving around the sun is a prominent example of circular motion in real life.The planets tend to follow a fixed circular orbit that acts as the boundary of the circle, while the sun acts as the centre of the circular path.

It provides a collection of different ways to draw the data to the drawing layer, run queries on it, and transform it into NetLogo Turtles or Patch data. This model loads four different GIS datasets: a point file of world cities, a polyline file of world rivers, a polygon file of countries, and a raster file of surface elevation. This model was built to test and demonstrate the functionality of the GIS NetLogo extension.

Note: If you download the NetLogo application, every model in the Models Library is included. (back to the library) GIS General Examples Nodes are turtles, edges are links.NetLogo Models Library: GIS General Examplesīeginners Interactive NetLogo Dictionary (BIND) This makes the network "bipartite." (You might position the two kinds of nodes in two straight lines.) NETLOGO FEATURES

Make two kinds of nodes, differentiated by color, then only allow links to connect two nodes that are different colors. If the world is a torus every patch will have eight neighbors, if wrapping is not allowed. These include neighbors, neighbors4, in-radius, and at-points: neighbors: reports the patches surrounding a patch or turtle both patches that share a side and those that share a corner.

Make some nodes into "hubs" (with lots of links). This code example shows how to use the basic neighborhood primitives.

Only connect nodes that are spatially close to each other.

Make sure each node has at least one link going in or out.

Connect every node to every other node.

Try other rules for connecting nodes besides totally randomly. Try calculating some statistics about the network that forms, for example the average degree. (Note: If you are already familiar with StarLogo or StarLogoT, then the material in the first four sections may already be familiar to you.) The Code Example models mentioned throughout can be found in the Code Examples section of the Models. Use the turtle variable label to label the nodes and/or links with some information. The following material explains some important features of programming in NetLogo. Try making it so you can drag the nodes around using the mouse. NetLogo supports directed links too, though.

In this particular example, the links are undirected. You can use it as the basis for your own model that actually does something with them.

This example doesn't do anything in particular with the nodes and links. The network consists of a collection of nodes, some of which are connected by links. This example demonstrates how to make a network in NetLogo. You can also Try running it in NetLogo Web If you download the NetLogo application, this model is included.
