representative fraction Latitude and Longitude b) Representative Fraction: – (RF) 1/100 is the ratio between the size of the drawing and the object. These formats are the representative fraction, the verbal statement, the graphic or bar scale, and the area scale. They are: 1. Answer: d. 27. When cartographic scale increases (like from 1:1,000,000 to 1:50,000) the area on Earth that can be displayed decreases, while the detail of the geography being represented can increase (for the area displayed). The smaller scale the topo map is, there will be less detail with more generalization, and the harder it will be to detect terrain features. 1. There are many situations in which the relationship between scale and the terms to which it is appended do not have easily described relationships with changes in spatial extent. Question: Geography Of Canada CGC 1DI (Academic) C) Representative Fraction (RF) 1:100,000 This Scale Has Traditionally Been The Most Difficult For People To Work With. The “size is equivalent to scale” relationship works nicely for internal classification schemes, or when a common process or feature can be used to determine how size and phenomena interact. Many maps state the nominal scale and may even display a bar scale (sometimes merely called a 'scale') to represent it. If your measurement on the map is 3 5/8 inches, that would be 3.63 miles on the ground. The most common type of graphic scale … Habitat for the individual bears must be available at a scale appropriate to provide a source of food and security (from other bears and humans). An example of a socially constructed scale would be a distinctive community within a city that is made up of culturally defined groups, and not necessarily related to a specific boundary or physical geographic space within the citiy’s limits. The graphic scale is sometimes called the bar scale, and the representative fraction is the RF or the fractional scale. Cartographic or representational scale is based on the mathematical relationship (ratio) between the extent of the representation and that which it represents. Such relationships suggest that in a given political jurisdiction the government will focus only on their mandate; in reality, however, there are many instances of “overreaching” by governments (for instance, the long “states rights” in the United States). Representations of Space and Spatial Representations, 8. As will be made evident below, problem scale is likely the more often used concept of scale than cartographic scale. Geography 15 (Lab) 1. 1: 50,000 (into metres) The spaces characterized by this type of scale generally do not have shared meaning, although geographers, and others, will often use scale to differentiate between different types of places, and the phenomena and processes unique to those places. The representative fraction (RF or fractional scale) is a ratio between the distance on the map and the distance on the real earth. Introduction and Perceptual Elements of Colour, IV. To measure distance on Google Maps you can use the bar scale found on the corner of the map. In addition, there are general references to the types of features that might be included in each spatial scale, including biotic and abiotic factors. Representative Fraction ( R. F. ): The third type of scale is R. F. It shows the relationship between the map distance and the corresponding ground distance in units of length. The scale can be represented as a fraction where the numerator refers to map distance and the denominator refers to ground distance. while small scale maps cover a large area in less detail. Most times the comparison of large scale and small scale maps can be relative.

Compass Basics However, the specific implementation of a climate change action plan is multi-scaled and does not equitably administer resources. Representative Fraction Scale: 05. Furthermore, recycling has the additional benefit of allowing waste to re-enter the supply stream in the local economy. Examples include the many environmental issues surrounding water and source water protection. A map’s scale indicates the relationship between the distances on the map and the actual distances on Earth. is equal to 50000 of the same unit on the ground. Finding a good fit for environmental policy, and what a policy’s purpose is, requires understanding the intended environmental outcome (global climate variability, water quality, biodiversity, recycling, etc.) When comparing the relative size of two cartographic scales we compare the size of the number calculated by the ratio of the size on the map (numerator) and the size on Earth (denominator). If the scale is a representative fraction (and looks like 1/100,000), multiply the distance of the ruler by the denominator (100,000 in this case), which denotes distance in the ruler units. Map scale is defined as the ratio of the distance between two points on the map to the corresponding distance on the ground. Representative Fraction (RF) - Fractional Scale - Ratio Scale: 1:50000 represents the map scale as a mathematical ratio or fraction, thus the name ratio scale or fractional scale. Such definitions are critical when considering environmental policy, as the community in question must be part of the decision- and policy-making process. Convert the given Representative Fraction (R.F.) On the other hand, recycling programs are considered substantially smaller scale problems that have both impacts and solutions that meet at a common scale. R.F. In this … Here such a scale means that one unit of measurment on the map is equal to 50000 of the same unit on the ground. Large scale maps cover a small area with great detail and accuracy, What is the verbal scale of this map? Answer: For graphical scale, to know the length of the line we need to make following calculations. Scale: 03. It has been used to describe differences in spatial extent as they extend to functional relationships that exist in both physical reality and policy outcomes. For example, the hierarchical nature of political systems (municipalities within provinces, or provinces within countries) simply means that decisions and policies implemented at the top will in turn affect smaller and smaller units as that policy “trickles down.” For instance, Canada’s signing onto the Kyoto Accord results in specific federal policies regarding climate change that govern the development of provincial policies and their implementation at the local level. Frames of Reference and Coordinate Systems, 12. In order for this definition to exist (urban scale), non-urban scales must exist, but these are not necessarily tied to changes in spatial extent or spatial properties of any kind (location, distance, area, etc.). Many compasses have a similar scale ruler on their base plate. The rulers can be found in both metric and English units of measurment. Certainly this is a likely outcome in a province like Saskatchewan that has distinct urban/rural communities that have quite different needs and exhibit different day-to-day behaviours. This Act addresses climate change issues that can be addressed by the province, while requiring that climate change and adaptation be addressed in concert with the federal government as well as partners around the world (other countries, multi-state organizations like the UN, G8, G20, and other influential bodies). Representative fraction scale (RF): Two other terms refer to the representative fraction scale - the fractional scale and the RF scale which is the scale ratio written in fractional form, 1/20,000. to twenty thousand". In the example below, the bar scale shows the distance on the map that represents ten kilometers or a little under six miles. Scale Conversion: 02. Representative Fraction is also known as Numerical Function. These types of scales are often said to be socially constructed, and while they have important spatial characteristics, they are not defined by their spatial nature. In terms of the scale of a particular environmental issue, an important question is whether the policy is intended to affect a local community or municipality or is it intended to impact a larger jurisdiction like a province, nation, or multinational region. country or state) with a small scale fraction is a small scale map (e.g. 2. 2. 22cm on the map, that would imply that you'll be traveling (22cm x 500m) / 1cm = 11000m or 11km on the ground. Representative Fraction : A method of scale of a map or plan expressed as a fraction showing the ratio between a unit distance on the map or plan, and the distance measured in the same units on the ground. Maps come in a variety of scales. ... Department of Geography, The Pennsylvania State University. [12b] Convert the line scale to a direct statement. Such scale expressions can be used to find the ground distance between any features from conversion of the corresponding map distance measurement.
