Week one Module one Forest surveying notes

kind of just the whole module and week things

Surveying is best defined as

the science, art, and technology by which lines, distances, angles, and elevations are established and measured on or beneath the Earth’s surface.

Surveying

measurement and mapping of our surrounding environment using mathematics, specialized technology, and equipment.

Examples of Famous surveyors

Washington, Lincoln, Jefferson, Thoreau, Fremont, Lewis and Clark, Boone, Cook, Earp, Disney

Lines

A continous extend of length between any two points

What does a line not have

It does not have width

Distance

A measurable amount of space between two points

Angle

The space between two points originating from a common point

Elevation

Altitude or vertical distance of a point above a common reference. Ex.) sea level

Construction staking

layout constructions lines for exact locations for buildings, bridges, roads or other engineering projects requiring accuarte location

Cadastral

Establish horizontal and/or vertical points of reference; establish new or existing property boundary lines

Topographic

create ground contours

Hydrographic

Create underwater contours or ground configuration

Photogrammetric

Create maps or collect data from ariel photography
