Earth Browser Concepts
Advantages of Web Maps: Web maps on earth browser can easily deliver up-to date information. If maps are generated automatically from databases , they can display information in almost realtime . They don't need to be printed or mastered and distributed. It is necessary to understand some keyworkd before we proceed to discussions of earth browser
Databases: A database is a collection of records or data that is stored in a computer system in rows or tupple format. So that computer programs or person can access these data from a query.
Real-Time: In computer science, a real-time computing is one that study of hardware and software systems which are subject to a "real-time constraint" which gives response as soon as event is generated.
Some of the example of realtime computing is displaying traffic signal when traffic datav is collected from traffic networks.
Another application of realtime is realtime images provided by earth browser these images are updated at the regular intervals.
Since Software and hardware for web maps are cheap so many online communities qare collaborating each other for producing web maps for example weather maps.
These images and data can easily be distributed. Because web maps distribute both logic and data with each request or loading, they are updated every time as the web user reloads the application.
Converse to traditional cartography,which deals with printed maps or interactive maps those are distributed on offline media for example CD and DVD ‘s etc. These maps need serious efforts to trigger a reprint or remastering as well as a redistribution of the media.
Distributed Databases: With web maps on eartth browser , data and product updates are easier, cheaper, and faster, and can occur more often. These web pages can work across various webbrowsers and operating systems and if they are based on open source then these compatible issues does’t matter
These web pages can access distributes databases using open standards and various API and they can integrate different data sources, if the map scale and data quality match.These use of centralized data sources removes the overhead for individual organizations to maintain copies of the same data sets.
Customization: One of the advantages of these maps is they can be customosed using user filters , personal preference , user is free to use and cofigure their own maps. User can also choose their own colors patters
Collaborative mapping: The of the gratest advantages of these web maps are they provide collaboration of latest technologies like HTML , DHTML, SVG, Java, Adobe Flash etc. these technologies need affords from many online communities however it is very important to understand that quality insurance factor is very important factor when we are applying technologies to use web maps.
Links: There are some links which can be found on earth browser related to some sensitive data these links are available on URL’s these URL are displayed in different colors, user can easily in different color.
Multimedia capabilities: These online maps on earth browser have various multimedia capabilities like playback, of video, audio and animation (SVG, SWF, and QuickTime) and other multimedia frameworks
