INSTRUMENTS used in Geographical Study






Dumpy Level 


It is an automatic level or levelling instrument used in survey of any part of the earth surface.


Prismatic Compass


It is a navigation and surveying instrument used to measure bearing of the traversing and included angles between end points.


Levelling Staff


It is also called levelling rod marked with height indication used to measure elevation of points, variation of topography.


Transit Theodolite


It is used to measure horizontal and vertical angles of any object with higher accuracy.


Plane Table


It is a graphical method of survey where field observation and survey plotting are done simultaneously. It is used for small scale mapping and cheaper than theodolite.


Barometer


It is a weather forecasting instrument used to measure air pressure. Different meteorological clarifications are available about barometer.

Wind vane


Wind vane or weather cock are used to identify direction of wind and it is placed in the highest point of any building.


Anemometer


It is used to measure wind velocity and forecast about storm or any weather disturbances.


Hygrometer


It is used in measuring amount of humidity and water vapor present in the air, soil or any confined spaces.



Rain gauge


It is basically meteorological and hydrological instrument to measure amount of rainfall occurred in any area.


Thermometer


It is also a weather related instrument also used in geography to identify temperature distribution and pressure variation.


Coriolis effect Kit


It is a demonstration type kit used to explain property of coriolis force, its momentum, angle of deflection.


Seismograph


It is used to measure magnitude and intensity of earth quake with the help of seismogram placed in it.


Geologic Compass


It is mostly used for rock strata mapping, dip of layers, axial plane and hinge line of folds etc.


Clinometer


It is rather known for Inclinometer used for angle of slope in mountainous region. Angle or elevation of river bank is also measured by this.


Stereoscope


It is a device for viewing stereoscopic pair of images or highly modified pictures using left and right eye combination. It helps to represent any two dimensional image into three dimension. It is vastly used in aerial photograph analysis.
