Anything that will be able to show shape and elevation. The data is provided in a grid or tileset with 72 columns and 24 rows.

Constructing A Topographic Profile

The simplest way to create a stl file from a topographic map is to use the website terrain2stl.

How to make topographic map. How to make a topographic map draw a contour line for the lowest level of elevation. These topographic elevations found mostly on online map can only be viewed in a macro scale level showing a minimum of 20m contour intervals. This is the area that will be used for the 3d model.

Right click on the layer contour and select properties. Record the hill on the side of the contour line. A topographic map is a map showing the third dimension elevation graphically.

Click on center to view under location. In order to build your 3d topo map you will need the supplies scissors glue a pen or marker to trace your elevations and the medium that you will use i used foam paper to make mine but you can use regular paper spaced out with foam shapes cardboard card stock etc. In order to do that we display what we call contour lines aka elevation curves.

Write down the symbols you use in your map key. Start drawing more contour lines for higher elevation scenarios. Go to symbology tab choose categories figure 15.

Search the desired area via drag drop on the google map. Go to https earthexplorer usgs gov and log in with your account. A red square will be shown in the middle of the map.

Delimit your zone of interest on the map. So here is what we do to make our topographic map. Choose the value field contour click add values button and add heights figure 16.

This line should follow the shape of the earth at that level of elevation. Create a compass direction the four arrows that designate north east south and west from which you will establish how the map will face. The compass is typically located on the corner of the poster.

Here is how to do that. We are locating the area on the worldwide coverage map for srtm data see image on the right of the space shuttle radar topography mission in 2000 which gathered elevation data for the entire world with 90m spatial resolution. Technically it is possible to label the elevation of each contour line more extensively up to 5 meters or less through 3 d modelling.

Topographic maps may have many contour lines.
