6.4. Data Models in GIS

Try these first

1. 1.

   What type of data does the Vector Data Model represent?

   Hint

   Think of how we depict different geographical features on a map.

2. 2.

   Give an example of raster data.

   Hint

   Remember, it’s usually represented in a grid format.

3. 3.

   What does the Vector Data Model primarily represent?

   • Continuous Data
   • Discrete Features
   • Elemental Data

   Hint

   Think about the type of data you need for precise mapping.

4. 4.

   True or False: Raster Data is best used for discrete features.

   • True
   • False

   Hint

   Recall how raster data is structured.

5. 5.

   Design a GIS application that requires both vector and raster data. Explain how each will be used and their interactions.

   Hint

   Consider how presence (vector) and movement (raster) can be integrated.

6. 6.

   Analyze a scenario where using raster data could lead to incorrect conclusions if precision is needed. Provide an example of real-world consequences.

   Hint

   Think about tasks requiring detailed boundaries.
