Think about a map of the world. The image you're picturing will most likely resemble the Mercator projection—a 2D representation of the globe created in the s which most maps you commonly come across are based on.

But despite its ubiquity, the Mercator projection does not accurately reflect the true size of countries given the impossibility of representing a 3D object on a 2D surface. In fact, the projection distorts the size of objects as the latitude increases from the equator to the poles, where the scale becomes infinite.

In order to more accurately depict the size of the countries, Neil Kaye, a climate scientist from the U. Met Office, has created a visualization of the Mercator projection in which countries morph into their true size. This demonstrates you can't fit shapes on a sphere back together again once you put them on the flat. The visualization clearly reveals how landmasses near the poles in the Mercator projection appear much larger than they actually are, relative to those nearer the equator.

For example: Antarctica appears as the biggest continent, despite it being the fifth largest in area; Alaska takes up as much area on the map as Brazil when, in reality, the South American nation's area is almost five times that of the U.

The Mercator projection was first introduced by the Flemish cartographer Gerardus Mercator in Despite its drawbacks, the projection became the standard map for nautical navigation because it enables navigators to plot a straight-line course and is still widely used for this purpose.

The projection has long faced criticism because of its alleged Eurocentrism with both Europe and North America appearing much larger than they actually are in comparison to Africa and South America.

According to critics, this reinforces the myth of white exceptionalism and depicts a view of the world rooted in the history of colonialism. Because of this and the distortions present in the Mercator projection, some people favor other representations, such as the Gall-Peters projection, although each of these has their own set of flaws. For example, the Gall-Peters projection—which is widely used in educational and business circles—shows the correct size of countries and continents in relation to each other but it's stretched out at the equator and squashed towards the poles.

This scale is used on the over 54, quadrangle maps covering the entire country. They are also called 7. The smaller the number on the bottom of the map scale, the more detailed the map will be. Here is an example of a Bar Scale found on a map. The scale shows that about 1. The smaller increments to the left of zero are each 1 mile and are used to estimate smaller distances. By including a map scale like the image above, if the map is photocopied and reduced in size, the scale can still be used.

Otherwise, 1 inch would no longer equal what it should. A large scale map shows greater detail because the scale is a larger fraction than a small scale map. Large scale maps have a scale ofor greater, Maps with scales fromtoare considered intermediate. Small scale maps are those with scales smaller thanA map of the world that fits on two pages of letter sized paper would be very small scale with a scale of aroundHere are 3 views of the same location on maps with different scales:. Why are maps like fish?

They both have scales! How about a metric map ofscale; 1 cm on the map is 25, cm meters on the ground. The difference is due to linear vs. To change from 10, torequires multiplying by a factor of Matt, I believe you have interpreted "large" to mean a linear measurement whereas the author presumably was thinking of a two dimensional "object" where "large" was referring to the area of the object.

So the ambiguity allows you both to be correct. Recent Comments David on Declination.I have master degree in GIS and Cartography. Best Regards Michael. I need more clarifications about area of digitizing and your needs.

ClankY Hi!Cadastral surveys are specially designed large scale surveys, generally on scale which are linked to land ownership and property. In case of urban cadastral surveys, the scales may be as large as to This paper is, however, emphasizing the rural and village properties.

The urban cadastre, although very vital needs a separate and detailed discussion. The importance of these land records is, of course, very high because it is only through the cadastral maps and land records that the owner gets legally linked to his property. This property may be a cultivated field, house or a fishing pond. The fact of the matter is that lack of updating the maps and the land records have given rise to the innumerable court cases.

The property related court cases are thriving because of the reduced importance of the cadastral surveys. The answer is emphatic YES. It is with this perspective that this paper has been prepared.

The fact is that cadastral surveys are the only unique surveys of their kind, which are directly connected with the masses. Special thought has, therefore, to be given for bringing lasting changes in cadastral surveys in India.

The scope of this paper is, however, limited to the surveys and mapping technology ies. The subsequent changes in the area of generating land records is not attempted for want of space. These estates were rather scattered so only village boundaries were established by the traverse method of surveying. The inside details of properties were left to local surveys. Survey of India as a Department of Government of India, established inwas fully involved in the process till Following the recommendation of the Committee of Government of India, the cadastral surveys were delegated in my opinion, abdicated!

The States evolved their. The change is bound to come due to the application of new technology whose appropriateness is to be proved through reducing cost, producing more village maps in a given time and generating more timely and reliable information. Example: The new technology may bring some changes in the area of plots which may be less than what is shown on the old map or Field Measurement Book FMB.

The authorities will have to adopt acceptable approach or strategy of gradual change with adequate time interval before new measurements are adopted. The Northern States of U. There was little input from Survey of India. InSurvey of India took to first aerial survey in Malda district of Bengal which was carried out to produce revenue maps on 16 inches to 1mile scale.

But no serious attempt was made to transfer the technology to the States. Again during war Survey of India adopted air-survey methods and later Photogrammetry in The situation regarding the technology in the States remained the same as was available in Later, inthe first State Cadastral Surveys conference was held in Mussoorie which was motivated by the concept that State Department of Settlement Surveys and Land Records should exchange ideas on the subject to provide technical solutions to, for example, town surveys etc.

The conferences have been regularly held but the progress has been rather slow. The Government of India Ministry of Rural Development has recently taken up computerization of records and introduction of other relevant technologies quite enthusiastically. This has been motivated, due to the success of Madhya Pradesh in utilizing the aerial photography and rectification process for substituting their plane-table graphical recordsimproving their record keeping systems and making the whole system farmer — friendly.Three 3 types of map scale represetation.

Since maps represent large areas, they cannot be drawn the same size as the real area on the ground. Maps are drawn small in comparison but they still give us the actual area they cover on the ground and the same distance between places. In order to do this, a map uses a scale. Accurate maps are therefore, normally drawn to scale. A scale is relationship between map distance and actual ground distance. For example 1 centimeter distance measured on the map represents 1 kilometer distance measured on the ground.

So when you measure 1 centimeter on the map, the actual distance on the ground represented will be 1 kilometer. You may say 1 centimeter measured on the map represents 1 kilometer measured on the ground or 1 centimeter to 1 kilometer. Notice that the statements mention two distances. The smaller distance refers to the map and the larger distance refers to the ground.

For the statement scale, the distance on the ground is always given in kilometers or meters. Thus, in this case, the distance of 1 cm on the map represents a distance of 1 kilometer on the ground.

The Representative Fraction R. What it means is that one unit measured on the map stands for ten of the same units on the ground. You can use any units that you are familiar with. So, you can say 1 centimeter represents 10 cm. On most maps, the Representative Fraction is given as a ratio, which is usuallyon topographic maps. Note that the larger the Representative Fraction denominator, the smaller the scale and the less detail that can be shown. A scale of will show more detail than a scale of The smaller the denominator of the Representative Fraction, the larger the scale and more detail can be shown for a given area.

The linear scale or line scale ; this is the most common scale used for maps and you need to really know how to use it. This is a special ruler that is drawn below a map that can be used to measure an area or distance. It is divided into a number of equal parts. The divisions on the line scale measures map distances and the labeling will give you the distance on the ground. To the right of zero — each scale division represents a distance of 1 kilometre.

To the left of zero — the distance representing 1 km is shown. This is subdivided into ten equal parts, each part representing a.The map scale is printed in the map legend.

It is given as a ratio of inches on the map corresponding to inches, feet, or miles on the ground. Ground distances on maps are usually given in feet or miles. Step 1. On the map 1 inch is equal to 0. What is the ground distance in feet? Set up the cancellation table so all units will cancel, except the desired unit, feet. The ground distance is 12, feet. Step 2.

Set up the cancellation table so all units will cancel, except the desired unit, miles. Step 3. Set up the cancellation table so all units will cancel, except the desired unit, inches. Occasionally, a map may not provide a scale. The scale can be calculated by knowing the distance between two points on the map, and measuring the distance on the map. Also, if a map has section lines, the distance between section lines is typically 1 mile. The known ground distance is 3, feet. How many inches is does this distance correspond to on the map?

Rearrange terms by multiplying each side by the measured distance and dividing each side by the map scale. Skip to main content. View Navigation. Place the acreage grid transparency over the area to be measured.

Count dots inside the sketched area. Count every other dot when dots fall on the boundary line. Multiply the total number of dots by the conversion factor on the map scale to determine the total acreage. See Table 5. Set up the cancellation table so all units will cancel, except the desired unit, chains. Use the map scale from Example 6 to find the map distance.Disclaimer: All efforts have been made to make this image accurate.
