![]() Finally, the advantage of wider dissemination can at the same time be a disadvantage when issues of privacy arise. Additionally, producing a map and publishing it on the web requires a very different skill set than producing and publishing a paper map. Paper maps also hold a distinct resolution advantage - 1200-3400 dots per inch (DPI) versus 65-120 DPI on a digital display. Even if we someday have a world in which access to the Internet is ubiquitous, Internet-based maps are vulnerable to problems of servers and networks going down and long download times. EarthBrowser, an Adobe Flash /AIR-based virtual globe with real-time weather forecasts, earthquakes, volcanoes, and webcams. It uses data from NASA, USGS, the CIA and the city of Osnabrück. Perhaps the most obvious disadvantage of internet based maps is that they require access to the internet. Earth3D, a program that visualizes the Earth in a real-time 3D view. While it's tempting to think that google earth's maps are preferable to paper maps in every way, that's certainly not the case. One could also argue that Internet-based maps have increased public awareness and demand for maps. They also allow for the possibility of interactivity (e.g., the ability to change scales and turn layers on/off) and connections to related information though hyperlinks. Among these advantages are that they are usually cheaper and less time-intensive to produce, easier to distribute to a wide audience and easier to update and maintain. Total destruction of buildings and facilities.Ever since the invention of the google earth, it has been an attractive medium for the publication of maps because of the many advantages maps published via the google earth hold over their traditional paper map counterparts. Mass destruction of buildings ġ2 (total) – changes of the relief on a large scale. Through the accumulation of rubble, lakes can form in the river valleys ġ1 (catastrophic) – numerous cracks on the surface of the earth, large avalanches in the mountains. Cracks in the ground up to 1 m wide, avalanches, landslides. The rate of increase of the cracks can be up to 2 cm/s ġ0 (destructive) – collapse of many buildings In others – serious damage. Landslides, collapse and falling debris into the mountains. Landslides and cracks up to a few centimeters on mountain slopes ĩ (devastating) – burglary of some buildings, falling walls, dividing walls and roofs. ħ (very strong) – significant damage to buildings Cracks in the plaster and breaking of individual pieces, thin cracks on the walls, cracks of chimneys Cracks in the foundations Ĩ (destructive) – destruction in buildings: large cracks on the walls, falling cornices and chimneys. An earthquake of magnitude 2 is subtle until the magnitude 7 is the lower limit of destructive earthquakes that cover large areas.ġ (undetectable) – only indicated by special devices Ģ (very low) – only felt by very sensitive pets and people in the upper floors of tall buildings ģ (low) – feels only in some buildings, like the vibration of a truck Ĥ (moderate) – the earthquake is felt by many people It is possible to balance open windows and doors ĥ (strong note) – shaking of hanging objects, noise in construction, window breakage, dust blowing Ħ (strong) – slight damage to construction of buildings, cracks in plaster, etc. Thus, the increase is a degree of magnitude of the 32-fold increase in the released seismic energy. Virtual Driver Interactive simulators are ideal for training our dispersed drivers. The most popular scale of energy evaluation in earthquakes is the local scale of the Richter magnitude. In the online 3D car simulator games on Silvergames.
