Discuss the proposition: "All natural entities are polygon entities, line and point entities are simply artifacts of map scale"

Organize the following terms in groups of terms that are (essentially) referring to the same thing;

node, chain, link, arc, point, vertex, edge, face, polygon, polyline

When combining the binary combinations of point, line and area entities there are nine different types according to L&T. What are these and discuss how they are important.

Provide two examples each of compound and complex entities.

Provide at least three examples of different point/area duals

Discuss the basic characteristics of the entity versus field oriented view of spatial information. In your discussion provide examples of both, the types of analyses that are/should be applied, the limitations of each view and its strengths. Also discuss the ways in which data from one orientation can be represented in the other.

The following entity types are commonly used to represent field data. Discuss how each approach "converts" field data to an entity, provide two specific examples of the types of data (e.g. elevation data) "converted" and the strength and weaknesses of each entity class.

1. sample points, lines, areas
2. isolines
3. connected pieces

L&T propose that there are seven types of analyses that include both spatial and non-spatial attributes of entities. What are the seven and provide at least two "real" examples.

Discuss the characteristics and relationship between data model, data modeling, data structure and file structure.

Discuss why the concept of "modifiable areal unit" is so critical to social scientists who are doing spatial analysis.

If data is in intensional form how can we convert it to extensional and vice versa?

What are the strengths and weaknesses of data storage in intensional and extensional form and how does this particularly apply to spatial data?

Discuss how the following terms relate to the use of coordinates in space as a system for locationg entities in space: origin, offset, geodetic reference system and horizontal datum.

According to L&T there are six different "concepts" of distance. What are they? Using a specific example that you choose, describe how the different concepts would yield the same/different distances from point A to B.
