Note: may have to refer back to data source to know what column names mean: District name (GLOBAL_A_1), country name (GLOBAL_A_3), and the number of confirmed ebola cases to date (V_ADM2_C3) Review the Data Note the column names of interest for the model (district name, country name, number of confirmed cases), and then close the file but do not save.dbf file for “Cases_at_Admin2” in excel or open office (do not save!). The dbf file contains the GIS data attributes that you will use in NetLogo. If you were starting from scratch, you would make two folders, one called ‘source_data’ and one called ‘data’.Make a folder for this project called ‘GIS_ebola’.

Pro Tip: Try to keep all of these together in the same folder! Reminder about Tabular Data

At least 4, but up to 8, files that end in the following. Shapefiles are actually composed of several component files. However, I encourage you to build upon the model to do this. We will not actually model the spread of the disease or be able to support the experiments with this base model.

Environment: (layers we want to show such as with GIS) Admin districts, treatment facilities, roads, cities, airportsįor this exercise we are only focusing on a sample model to bring in the GIS and CSV data into NetLogo, based on these themes above.

Agents: People (categories based on SEIR model).

Spatial Scope: Africa > Sierra Leone > district level.

Experiments: Identify impacts on rate of spread, if restrict travel.

What is being modeled: spread of ebola, rate of spread.

Trouble-shooting and test throughout the process.

Importing data and building a NetLogo model.

Getting/Organizing/Reviewing/Cleaning Data.

GIS and data acquisition/cleaning/processing may be time intensive and require tools like QGIS and Open Office.

GIS data may slow down model load and run time.

At detailed map scale, challenge to get spatial reference system to match Netlogo reference such that 10 km = distance of 1 patch, for example.

Need realistic agent behavior to correspond with spatial scale of model with GIS.

It is not challenging to add GIS and CSV data to Netlogo.

Can be more visually appealing with layers of information displayed in Netlogo.

GIS data can provide attributes that can be used by patches and agents that would be too time consuming to manually code.Support more “realistic” models and tie model to a specific place.Using the GIS extension, you can use geographic data that is vector format as shapefiles or raster data as ASCII and TIFF.
