WHAT IS IT?

Netlogo includes a GIS Extension that allows you to load vector and raster data into your model as well as perform some basic GIS operations. Theses extensions support vector data in the form of ESRI shapefiles and raster data in the form of ESRI ASCII Grid files. This model however is a shapefile of Ohio State University campus imported into Netlogo through the use of these GIS extensions.

HOW IT WORKS

We first define a transformation between GIS data space and netlogo space. We then load our datasets and performs GIS operations with the datasets. One way of defining a transformation between GIS space and Netlogo space is to take the union of the 'envelopes' or the bounding rectangles of all yur GIS data and map that directly to the bounds of the Netlogo world. Once coordinate system are defined we cn load our data set using gis:load-dataset

HOW TO USE IT

Use the setup to prepare Netlogo world. First load the display-pavement to display all pavements from the shapefile. Next, click on the display-building to display all buildings from the shapefile. Click on te create-netlogo-data to fill in all paches for pavements and buildings. You can control the display of labels by using the hide-labels or show labels button.
