Equidistantlength is preserved, usually on large scale maps
Large scalesmall area
small scalelarge area
equal areaarea preserving, shape of the earth changes cannot be angle preserving

What is a thematic map?shows the spatial distribution of some type of data over a geographic area
What is a Planimetric map?shows the horizontal position of boundaries, bodies of water, economic and cultural features
what is a topographic map?portrays physical relief through the use of contour lines that connect all points at the same elevation
true or false, elevation lines that are closer together equate to steeper elevation?true
equally spaced elevation linesuniform graph
steeper at the top and less elevated at the bottom would produce what graphconcave graph
less steep at the top and more steep at the bottom would produce what graph...convex
When would you use hatched contour lines?when drawing a depression
When drawing a river what does the base of the V represent?The base of the V points upstream (against the current)
What landform is an obvious violation of topographic maps?overhangs in canyons or cliffs because the elevation is too steep to show with contour lines
