Geographic Information System (GIS)

A geographic information system (GIS) integrates hardware,

software, and data for capturing, managing, analyzing, and

displaying all forms of geographically referenced information.

Geographic Information System (GIS)

GIS allows us to view, understand, question, interpret, and

visualize data in many ways that reveal relationships, patterns,

and trends in the form of maps, globes, reports, and charts.

A GIS helps you answer questions and solve problems by

looking at your data in a way that is quickly understood and

easily shared.

GIS technology can be integrated into any enterprise information

system framework.

GIS may be used in archaeology, geography, cartography,

land surveying, public utility management, natural

resource management, precision agriculture,

photogrammetry, urban planning, emergency management,

landscape architecture, navigation,

What goes beyond a GIS is a spatial data infrastructure

(SDI), a concept that has no such restrictive boundaries.

Therefore, in a general sense, the term describes any

information system that integrates, stores, edits, analyzes,

shares, and displays geographic information for informing

decision making.

GIS applications/softwares are tools that allow users to

create interactive queries (user-created searches), analyze

spatial information, edit data, maps, and present the results

of all these operations

The year 1960 was the development of the world's first

true operational GIS in Ottawa, Ontario, Canada by the

federal Department of Forestry and Rural Development.

Developed by Dr. Roger Tomlinson, it was called the

"Canada Geographic Information System" (CGIS) and

was used to store, analyze, and manipulate data

collected for the Canada Land Inventory (CLI) – an

effort to determine the land capability for rural Canada

by mapping information about soils, agriculture,

EDM (Electromagnetic

Distance Measurement)

♦ Two types of instruments

– Electronic or microwave type (50 m to 50

km)

– Electro-optical type (used by Civil Engrs), up

to 1 km

• Infra red carrier beam is emitted by diode of EDM

• the emitted beam is reflected by prism

♦ Kern Makometer is a latest high precision

EDM

Total Station

♦ Total station = Theodolite + EDM

♦ Smart total station = Total Station + GPS

+ ?? + ??

♦ Robotic total station
