Try these first

1. 1.

   What is GIS and why is it important in hydrographic surveying?

   Hint

   Think about data integration and visualization.

2. 2.

   Define georeferencing.

   Hint

   Consider how maps relate to real-world coordinates.

3. 3.

   What is the primary function of GIS in hydrographic surveying?

   • Integrating spatial data
   • Only for visualization
   • Storing data without analysis

   Hint

   Consider the multiple functions of GIS.

4. 4.

   True or False: Thematic maps only show elevation differences.

   • True
   • False

   Hint

   Think about what themes can be mapped.

5. 5.

   You are tasked with creating a map for a new waterway. Explain how you would use GIS to integrate bathymetric and environmental data to identify the best navigational route.

   Hint

   Think about the steps required to ensure navigational safety before creating the map.

6. 6.

   Describe a situation where thematic mapping could directly influence environmental decision-making in coastal management. Discuss the role of spatial querying in this context.

   Hint

   Consider the real-world implications of thematic maps in recognizing environmental concerns.
