Which input layers are used in the cellular automata model shown in this clip?
The model uses a main raster plus four auxiliary raster layers: Road distance, CBD distance, Population density, and Slope. Each layer is represented as a small matrix aligned with the main raster so that the same row and column can be compared cell by cell.
Conditions
- All displayed matrices have the same number of rows and columns.
- The auxiliary layers are used as inputs for threshold checking.
Reasoning, step by step
- Identify the main raster containing the land cover classes.
- Locate the four auxiliary matrices displayed beside the main raster.
- Note their labels: Road distance, CBD distance, Population density, and Slope.
- Understand that these layers provide the spatial attributes checked against user-defined thresholds.
Example
The slide titled Model Algorithm shows one large main raster and four smaller matrices labeled Road distance, CBD distance, Population density, and Slope. The speaker names these layers as the inputs checked by the algorithm.
Common misconceptions
- One might think the tiny matrices shown on the slide are the actual working scale of the model inputs. The speaker explicitly states that the matrices are enlarged simplified examples for visibility, while the real study uses full land-cover maps.
