[QUOTE="diggit, post: 608855, member: 3031"] If only someone who designed many systems such as geovic or a land surveyor or cartographer could chime in. :D :lol: [b]How Scale Affects Feature Representation[/b] The larger the scale of the map, the better the features that can be detailed. A map that shows the water network of a small area may show the river as a polygon layer and will show the tributaries of that river. A small scale map covering the area would show that same river as a line feature and the tributaries would be removed (a process known as generalization). The smaller the scale of the map, the less the actual detail of a feature is preserved. Smaller scale maps have river features that have the lines smoothed out whereas a large scale map would show more detail about the twists and turns of that same river. So why not show the same level of detail regardless of the map scale? There are two main reasons. The first reason is the noise level. Showing a lot of detail for features on a small scale map would cause a lot of confusion on the map. By reducing the amount of detail to show only the most important aspects of a feature, the map shows a clearer picture of the area. The second reason is the file size. Features that have a lot of detail are larger in file size. For a small scale map, loading several large layers will slow down the map production. [/QUOTE]
