Question

What does the conventional symbol at grid reference 145132 mean?

Answer 1

Hint: It is an exact point on a map with a rise recorded alongside it that speaks to its stature over a given datum. Not at all like a seat mark, which is set apart by a circle or plate, there is no official sign of spot tallness on the ground albeit, in the open nation, spot statutes may once in a while be set apart by cairns.

Complete step-by-step solutionA map is an emblematic portrayal of accentuating connections between components of some space, for example, articles, locales, or topics. Numerous maps are static, fixed to paper, or some other sturdy medium, while others are dynamic or intelligent. Albeit most usually used to portray geology, maps may speak to any space, genuine or anecdotal, regardless of setting or scale, for example, in cerebrum planning, DNA planning, or PC network geography planning. The space being planned might be two dimensional, for example, the outside of the earth, three dimensional, for example, the inside of the earth, or considerably more theoretical spaces of any measurement, emerge in displaying marvels having numerous free factors. Numerous maps are attracted to a scale communicated as a proportion, for example, $1:10000$, which implies that 1 unit of estimation on the map relates to 10,000 of that equivalent unit on the ground. The scale explanation can be exact when the area planned is little enough for the arch of the Earth to be disregarded, for example, a city map. Planning bigger locales, where bend can't be overlooked, expects projections to plan from the bent surface of the Earth to the plane. A spot stature is an accurate point on a map with a rise recorded alongside it that speaks to its tallness over a given datum. It is known as Ordnance Datum in the UK. Dissimilar to a seat mark, which is set apart by a circle or plate, there is no official sign of spot tallness on the ground albeit, in the open nation, spot statutes may now and again be set apart by cairns. In geoscience, it tends to be utilized for demonstrating rises on a map, close by forms, seat marks, and so on.

Thus, the correct answer is spot height- 270.
