A team wants one layer containing both point locations and line routes. Which statement should guide its format choice?
- A
Use a Shapefile layer, because it combines geometry types in one layer
- B
Use a raster, because raster cells can store point and line geometries
- C
Do not use one Shapefile layer for both geometry types; a Shapefile layer supports one geometry type
- D
Use a GeoTIFF, because it is a vector format for mixed geometries

A road layer has a numeric field named speed_limit, but its documentation does not state the units. What is the most important improvement for interpreting this attribute?
- A
The field is sufficient because its name identifies the kind of value
- B
The field needs clear units so users can interpret its values
- C
The field should be converted to a geometry type
- D
The field should be deleted because attributes cannot store numbers

A municipality is evaluating a road network's location and descriptive information. Which checks directly assess positional accuracy or attribute accuracy? Select all that apply.
- A
Compare mapped road locations with reliable reference locations
- B
Check whether the dataset is stored in a particular file extension
- C
Verify that road names and classifications are correct
- D
Reduce the raster cell size to establish that road names are correct

A GIS analyst needs to explain both how a dataset organizes its spatial information and how the dataset is stored for exchange. Which distinction is correct?
- A
The data model describes how the information is organized; the file format is a way to store or exchange it
- B
The data model is the filename extension; the file format is the dataset's coordinate reference system
- C
The data model describes quality checks; the file format determines positional accuracy
- D
The data model and file format are interchangeable terms for the same thing

A regional study needs to represent elevation as a continuous surface. Which data model is a suitable choice?
- A
A vector point layer, because every elevation value must be a separate named feature
- B
A vector polygon layer, because elevation data always represent administrative areas
- C
A raster grid, with elevation values stored in its cells
- D
A file extension, because it determines how elevation varies across space

Which statement describes a capability of GeoTIFF?
- A
It stores vector points, lines, and polygons but cannot store raster values.
- B
It can store raster values along with georeferencing information.
- C
It stores only attribute tables, without spatial information.
- D
It stores raster values but cannot include information about their geographic location.

A spatial dataset contains an attribute field whose meaning and valid entries are unclear. What is the most appropriate improvement?
- A
Document what the field represents and which values are permitted.
- B
Remove the field because attribute values should not be documented.
- C
Change the coordinate reference system so the field has a clearer meaning.
- D
Convert the vector layer to a raster so its attribute values are self-explanatory.
