Lewis and Clark used a combination of celestial navigation tools, such as a magnetic compass and sextant, along with basic surveying techniques to create their maps during their expedition. They also relied on notes and sketches made by both members of the expedition and Native American guides to fill in details on their maps.
Lewis and Clark used a variety of tools to make their maps, including a magnetic compass, a surveyor's compass, a sextant for determining latitude, an artificial horizon for determining longitude, and a chronometer for keeping time. They also relied on simple tools like an odometer wheel for measuring distances and a theodolite for measuring angles.
Lewis and Clark stood at various vantage points, such as hilltops or riverbanks, to survey the land and make maps during their expedition through the western United States. They would often use instruments like compasses and sextants to determine their location and record detailed observations of the terrain.
Businesses use topographic maps for site selection, resource planning, and infrastructure development. Governments use topographic maps for urban planning, disaster management, and environmental conservation. Both sectors rely on these maps to make informed decisions based on accurate geographical data.
