Creativity is a crucial aspect of human life that allows us to generate new and innovative ideas, solve problems, and express ourselves in unique ways. It is a valuable skill that has the potential to benefit individuals, communities, and society as a whole. Therefore, it is important to nurture and encourage creativity in all aspects of life, including education.
However, there is a widespread belief that schools often kill creativity. Many people argue that the traditional education system, with its emphasis on memorization, standardized testing, and conformity, stifles creativity and discourages students from thinking outside the box. In this essay, we will explore this claim and consider whether schools really do kill creativity.
One reason why some people believe that schools kill creativity is that they place a strong emphasis on conformity and the correct answers. Students are often expected to follow rules and procedures, and deviations from the norm are not always encouraged or rewarded. This can create a culture of fear and conformity, where students are afraid to take risks or express themselves in unique ways.
Another reason why some people believe that schools kill creativity is that they focus primarily on academic subjects, such as math, science, and language arts. While these subjects are important, they do not always provide opportunities for students to engage in creative activities. For example, a student may be asked to solve a math problem or write an essay, but they may not have the opportunity to design a product, create a piece of art, or engage in other forms of creative expression.
Additionally, the pressure to perform well on standardized tests can also limit creativity. Schools often place a great deal of emphasis on test scores, and students may feel pressure to focus on preparing for these tests rather than exploring their own interests and passions. This can lead to a narrow focus on academic subjects and a lack of time for creative pursuits.
However, it is important to note that not all schools kill creativity. Some schools, particularly those that adopt a more progressive approach to education, actively encourage creativity and allow students to explore their own interests and passions. These schools may use project-based learning, inquiry-based learning, and other pedagogical approaches that give students the opportunity to engage in creative activities and express themselves in unique ways.
In conclusion, while it is true that some schools may discourage creativity, it is important to recognize that not all schools are the same. Some schools actively encourage creativity and provide students with the opportunity to explore their own interests and passions. Therefore, it is important for educators, parents, and policy makers to consider ways to nurture and encourage creativity in all aspects of education.
Once the photography has been acquired and the necessary triangulation calculations have been completed, the photography is ready for the digital elevation model collection. Several civil mapping agencies make use of the above mentioned method in producing photomaps, e. The humble objective of the conference is to 'take the benefits of geographic information technologies to a wide canvas of applicable areas, particularly in the realms of development, environment and social well-being'. An interesting side note is while orthorectification removes horizontal distortion, vertical relief displacement is still maintained. What is the purpose of topographic maps? Second-generation digital orthophoto imagery is becoming popular throughout the GIS Industries as cost-effective, timely and able to retain accuracy. With respect to horizontal accuracy, National Map Accuracy Standards state that "1.
This is one of the most accurate models to be able to show the real physical space and help to solve problems from the specialist's office. May study grasslands and meadows or do phytosanitary investigations of specific crops. Regardless of the method of construction, four basic operations or corrections must be applied to the standard vertical aerial photograph to produce the orthophoto. Radiometric corrections may be necessary to smooth tone or color differences between orthoimages to improve the overall image quality. GCPs were determined by Trimble 5800 GPS.
Project area is about 162 km 2. Figure 12 illustrates the use of the digital orthophoto as a backdrop to a vector display of property ownership lines and the community road network. As with using GCPs, the mathematical relationship between the real world coordinates and the scanned aerial photograph is determined and the digital image is resampled to create the rectified image. In 1960s virtually all the major photogrammetric instrument manufacturers produced orthophotoscopes based on previous analogue instruments. In this article we are going to tell you what the orthophoto is, what are its characteristics and how important they are. In the ideal situation, one aerial photograph will be used to create an entire orthophoto. It also aims at internationalization of education and has become a venue where academicians, researchers, students, scientists and technologists from across the globe can come together in a very open environment of scientific debate and come out enriched from such encounters.
This natural occurring phenomenon occurs when the angle of incidence of the sun light striking the smooth water surface equals the angle of reflection up to the camera. Find Out How UKEssays. This led to the OS using only orthophotos as revision tools in conventional line-mapping programs. Perhaps the best way to sample the spatial accuracy is to use the Global Positioning System or GPS. Most users are utilizing these images for GIS maintenance, community planning, hazard mapping, disaster planning and commonly for any urgent planning purposes within short time, while line maps would not be at hand due to longer time in producing them. Imagery and Ground Control: Suitable variety of imagery scale and ground control as known above is important to the dependability of the final orthophoto.
Shave one to three months of project duration. Orthophotographs is readily used for measurement and spatial analyses due to the fact that they maintain a regular scale across the image. Scope of natural resources One of the areas where the use of orthophoto is most widespread is in natural resources. Maps with no scale give an unfortunate thought of distances and maps with no legend are much of the time confounding to the client. Traditional orthophotos are correct at the terrain level.

The conference has over the years moved from Asia Trivandrum, 2008 to Europe Stuttgart, 2009 , to South America Arequipa, 2010 , to Africa Nairobi, 2011 and back to Asia Malaysia, 2012. Orthophoto maps are a combination of a vertical aerial photograph and a topographical map. Bean was the first to produce a practical instrument to bring about the process, he also introduced the term Orthophotography. In subtle alignment cases, the error might not warrant rejection due to National Map Accuracy criteria, however the visual quality of the map may be compromised to a point that recreation of one or both images may be warranted. An example is shown below using the same sample data line from above. A review is given of the techniques that are available to extract relevant information from multi-temporal aerial photographs for use in the monitoring stage of landslide assessments.
Once an aerial photo has been orthorectified, it is commonly referred to as an orthophoto. The early 1990s saw the advent of the end-to-end softcopy-based system, or Digital Photogrammetric Workstation DPW. The thick black line between the images illustrates a lack of data and would be the result of operator error. During 1970s Hobrough introduced an analytical instrument, Gestalt Photo Mapper GPM that uses image correlation to create a Digital Elevation Model DEM. Where possible overlay the imagery with a linear coverage like a road or stream network from another map source to help look for spatial errors.

Maps are used to give the location or position of places or features. In the Vermont evaluation, the road network was available in an ARC coverage format and was consistently drawn on top of the digital orthophoto during the visual quality verification. Also in recent years, Light Detection and Ranging LiDAR technology became a significant factor in producing advance and accurate topographic data. The topographic mapis a smaller scale map so everything is shown in more detail whereas an orthophotois a larger scale map and only certain things are shown. .
Orthophoto: what it is, characteristics and what it is for
The more topographically diverse the landscape, the more distortion inherent in the photograph. The orthorectification process ties each pixel in a digital image to its true earth location. This enables orthophotographs to be used in their primary role as a backdrop on which map features can be overlaid. The traditional orthophotograph rectification displaces buildings and bridges, which are both modelled in the digital terrain models. In addition to this model for obtaining aerial photos, various orthophotos of proven qualities are made in various parts of the world. If the terrain photographed was approximately flat, within + 25 meters on 1:50,000 scale photography, the resulting rectified photo could be considered an orthophoto.
Tiling and Formatting: The conclusive orthophoto image is in the end broken into smaller areas that are more convenient to handle by the end user. For this scale product, the original photography is acquired at a nominal scale of 1:30,000. Within certain limits, normally equivalent to photogrammetric plotting, the orthophotograph is a scale correct, orthogonal projection of the terrain photographed. Orthophotomap is one in which the line-work and symbols of a conventional map are replaced by the orthophotographic image. Finding points away from major road intersections should be considered. Digital orthophotograph has become a commercial production reality due to the primarily increased availability of more powerful computers at reasonable prices.
