Abstract

We rarely think about the accuracy of the measurements we carry out. The present paper explains some of the benefits of thinking about errors as well as the many ways by which errors affect our measurements in natural geography in order to remove related uncertainties.
Basically, natural geography is still a science dependent on field studies, and for natural geographic examinations we need to measure the size of natural shapes and environmental processes. For example, in the 2010 AEB-A Curriculum, volunteers are expected to conduct field research in which it is necessary to collect, record and interpret raw field data accurately.
The best example is calculation of river flow rate, which requires the measurement of the two parameters of river’s shape of passageway and velocity of the flow.
