We build a little random walk agent-based model. packages including ArcGIS, R, the HEC Suite of hydrological tools and NetLogo. 8.61K subscribers Subscribe 90K views 10 years ago NetLogo Programming Tutorials An introduction to the NetLogo programming language. HOW IT WORKS 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 is a GIS-oriented class that will rely on statistical modeling. Where appropriate, we highlight the main issues that need to be considered when using a GIS and agent-based modelling.

Using QGIS, we demonstrate how to prepare and manipulate some example GIS data.

You can access the tutorial through the resources tab of this blog. This model was built to test and demonstrate the functionality of the GIS NetLogo extension. A brief overview of the development of GIS is given along with a flavour of the main software available. You will learn how to create a network, how to perform different network layouts, how simulate a network creation process, how to simulate a trade process taking place on the network, and how to analyse the network. I just wrote a step-by-step tutorial on how to do network science with Netlogo. Moreover, learning Netlogo is a great way to get into coding.

Loading and Displaying Data The code below load a shapefile on setup and then display it when the 'display-countries' button is pressed. Indeed, its often called the sketchbook of programming languages. The GIS extension for NetLogo allows you to load and display GIS information in ASCII Grid files and shapefiles. The code then assigns the agents to the region they are spawned in. Agent attributes are set, with two of them being randomly generated between 0-1 (EJknowledge and EJtranslation). ENVI, Google Earth, Paraview, PostgreSQL and PostGIS, Idrisi, Inkscape, Landserf, GIMP, GRASS GIS, gvSIG, Mapserver, Netlogo, QGIS, PAUP, R and RePast. It is by far the easiest way of rapidly implementing ideas for social network mechanisms. gis gis extension tutorials Visible to everyone Changeable by the author Model was written in NetLogo 5.0. As seen below, I am using the GIS extension to load in a regional shapefile and then randomly distribute agents based on a slider in the interface. The standard open-source free installation of Netlogo allows you to represent, analyse and simulate networks with great ease and a nice visual user interface.
The NetLogo GIS extension can handle both raster and. Netlogo actually has amazing built-in capabilities for doing network science. Adding GIS data to your NetLogo model is useful when you want to create visualizations of spatial data. Netlogo is an awesome piece of software! Its main functions are performed by turtles and its code can be written by babies… I rest my case!
