GIS Structure
GAMA models are built on top of GIS layers that build geography of the model’s world. An overview of the GIS layer structure and object attributes used for CityScope models is below.
| File Type | Type |
|---|---|
| Buildings.shp | Polygon |
| Roads.shp | Line |
| table_bounds.shp | Polygon |
| Amenities.shp | Point |
| Bounds.shp | Polygon |
| Attribute Name | Values |
|---|---|
| Usage | ‘O’: office, ‘R’: Residential |
| Scale | 'S': small, 'M': Medium, 'L': large |
| Category | 'Uni': university, 'Shopping': commercial area, 'Restaurant': dining area, 'Night': nightlife, 'Park': communal greenspace, 'HS': high school, 'Cultural': areas of cultural significance |
| Floors | From 0 to 100 |
Empty attribute table.
This layer represents the bounds of the CityScope physical table grid inside of the simulation.
Point representing lunch/dinner break options for each agent in the simulation. Each point will represent the location of a restaurant, convenience store, or supermarket for example - anywhere someone can sit down and eat.
| Attribute Name | Description |
|---|---|
| Type | The type of amenity this is (e.g. ‘restaurant’, ‘pub’, ‘fast food’) |
| Name | The name of the amenity (e.g. ‘Saul’s Deli’, ‘In-N-Out Burger’) |
| Usage | Each object should have this set to 'A' |
| Scale | TBD |
Represents the bounds of the simulation. Agents will not be able to exit this perimeter. Empty attribute table.
