This is really handy if you want to work directly with data downloaded from other sources or recorded using GPS in the field. Set scooter-dataset gis:load-dataset "C:/shape/scooter. The NetLogo GIS extension allows for standard GIS data formats to be added to and manipulated by a NetLogo model. Set roads-dataset gis:load-dataset "C:/shape/roads.shp" Then the models can be run by loading them into NetLogo. The easiest way to run the models is to download this whole repository and extract the zip file. Gis:load-coordinate-system (word "C:/Program Files/NetLogo 5.3.1/app/models/Code Examples/GIS/data/WGS_84_Geographic.prj") The NetLogo models, however, often need some accompanying data. Netlogo is a multi-agent programmable modeling environment, and the GIS extension enables its capability of processing, modeling and analyzing geo-data. Then you need to place the scooters onto the coordinates from the line network, and then you can "ask" them to move around. NetLogo doesn't do that for you, you need to iterate over all the features, line segments and coordinates yourself. And I need a function to create possible moving turtles out of the point-shapefile, but also I need to let them know to only use the lines instead of the whole area.Īfter loading the lines shape file you need to convert these into a network of agents/turtles and link them. So, as far as I know, I need a to go function where I want to move the turtles.
#Netlogo gis how to
In the first model (as shown in the movie below) we use the polygons to be individual agents. The desktop version of NetLogo is recommended for most uses See here for more information on how to use NetLogo Web. Both are based on using a shapefile to create Schelling -inspired segregation model. grd) and vector shapefiles (.shp), can be read with the use of the gis:load-dataset 'name. We would like to showcase two simple models. Various raster file formats, such as ascii grid (.asc and. Let people gis:load-dataset "scooters_Amsterdam.shp" Using Shapefiles in NetLogo Carrying on with the theme of linking GIS to NetLogo for creating agent-based models. Let network gis:load-dataset "Roads_Asmterdam.shp" It provides the ability to load vector GIS data (points, lines, and polygons).
#Netlogo gis code
So far, my code is just this: extensions This extension adds GIS (Geographic Information Systems) support to NetLogo.
#Netlogo gis trial
I have found little help so far on the internet and it won't work with trial and error. Could someone give me a headstart by helping me to create turtles from the scooter registrations (points) and let them move over the network lines. Since I am new to Netlogo, I only managed to load these shapefiles in my model. The idea is to have them drive through the city on the lines of the network shapefile. I have two shapefiles I want to use: a network map of a city (line-shapefile) and a point-shapefile of scooters in the city. Box 6.2 NetLogo's GIS extension NetLogo's GIS extension provides support for reading both vector data (in the form of ESRI shapefiles) and raster data (in. I'm just starting with using Netlogo to create an Agent Based Model.
