For questions 18 to 21, reai geographic features are mamed Which length dimension Lo LI. L2 or L3) ofthe database object would best represent each of thesefoanres in a GI ystem deveiopad for mapping at the 1:50,000 scaie. Hint: IO is the line dimension for poimt! 18) The best geographic representation of the length dimension for highway is: a) LO b) LI c) L2 d) L3 19) The best geographic representation of the length dimension for woodland is: a) LO b) Ll c) L2 d) L3 20) The best geographic representation of the length dimension for mountains is a) LO b) Ll c)L2 d) L3

Explanation / Answer

11. The most probable option is b) when you don't have the appropriate permission to read the data.

13.The correct option is a) Source tab where you can view the coordinate system of the layer.

18. An increase in the length dimension (L1 or L2 or L3) will cover lesser part of the land. The areal extent of the features can be placed in the following order:

Woodland > Mountain > Highway.

Thus, for a highway, the best geographic representation is L3, as the feature will be the smallest on a map of 1:50,000 scale.

For a woodland, the best geographic representation is L0, as the feature will be the biggest on the map.

For mountains, the best geographic representation is L1, as the feature will be much bigger than the highway but a bit smaller than the woodland.
