Introduction to GIS
• Many of the issues in our world have a critical spatial component!
– Land management
– Property lines, easements, right of ways
– Data on land values, taxation, assessment
– Business site selection, advertising
– Proximity of ‘our’ land to other facilities (pollution, hunting, municipal, federal, state)
– Hydrology: Soil, Elevation, Structures , vegetation
– Crime analysis
– Emergency management and disaster preparation
Introduction to GIS
The Earth is finite!
– If not now, within our lifetimes there may be no natural ecosystems.
– Land managers, natural resource workers, and politicians are and will continue to make decisions about biological systems.
– Good information and tools are needed to do this.
The Space on Earth
Introduction to GIS
A computer-based tool for
• holding,
• displaying,
• analyzing, and
• manipulating,
spatial data.

Distance Measurement
Horizontal and Vertical Distance Measurement
Point A
Point B Direct Method Using a Tape
Horizontal Distance = L cos θ
Vertical Distance = L sin θ
Temperature may affect the measuring tape.
Problems?
The pull/tension applied to the tape in the field may be different from the standardization pull.
Tape sagging (mainly for long tapes)

Indirect Leveling
Benchmark A Elev. = 303.00
Elev. = ? Point B V = L sin θ
= (451.00 ft) * sin 3o15’
= 25.57 ft
Elev. B = Elev. A + HI ± V –RR
= 303.00 + 5.4 +25.57 - 6.40
= 327.57 ft
