Topographic maps are also commonly called contour maps or topo maps.

Order a paper map from the usgs store. 3d models are an easier way to see what the earth looks like this is an easy set of instructions to make your own 3d model of an area shown on a topographic map. Contours are to be placed every ten feet. The position of the objects on the map does not have to correspond to their real life locations.

To draw a topological map you need to draw a symbol for each location and a bunch of lines connecting them together representing the routes between them. Topographic maps are a 2d way to show elevation and shape on a map. Step 2 establish a scale which will represent the distance. Topographic maps conventionally show topography or land contours by means of contour lines.

From the maps you have aqcuired record elevation levels compass scale and any landmarks. In many cases this line is given to you often labeled something like a a or a b. As long as you know how to read them you should be able to visualize what that area looks like on the actual earth. Topographic maps are covered in contour lines.

Download the geopdf map file and send it to a local printing. There are three ways to get full scale plots of usgs topographic quadrangle maps including both historical topographic maps produced 1884 2006 and us topo maps produced 2009 present.

Use the thicker contour lines to determine the elevation. Determine the location you want to map and gather maps of that location from local libraries or internet resources such as the link in the resources section.

In other words every point on the marked line of 100 m elevation is 100 m above mean sea level. Contour lines are curves that connect contiguous points of the same altitude.
