इसरो का 'भुवन' दिखाएगा दुनियाभर
एक ही समय एक ही स्थान से पूरी दुनिया की सैर कराने वाले सॉफ्टवेयर गूगल अर्थ की तर्ज पर भारतीय अंतरिक्ष अनुसंधान (इसरो) ने भी अपनी एक प्रणाली तैयार कर ली है। 'भुवन' नाम की इस सेवा का शुभारंभ बुधवार को किया जाएगा। इस वेबपोर्टल के जरिए कोई भी अपने कम्प्यूटर पर दुनियाभर की सैटेलाइट तस्वीरें देख सकेगा।

भुवन संस्कृत का एक शब्द है, जिसका मतलब हिन्दी में पृथ्वी होता है। इसके जरिए इंटरनेट उपभोक्ता दुनिया के किसी भी स्थान का नजारा देख सकेगा, लेकिन सैन्य व परमाणु प्रतिष्ठान जैसे संवेदनशील स्थान इसमें दिखाई नहीं देंगे। भुवन का शुभारंभ इसरो के अध्यक्ष जी. माधवन नायर करेंगे।
भुवन वेबपोर्टल में दिखाई देने वाली तस्वीरें इसरो के सात रिमोट सेंसिंग सैटेलाइटों से एक वर्ष पूर्व ली गई थी। इसमें आसमान में काफी ऊपर से दिखने वाली पृथ्वी की तस्वीरें, सड़क पर चलती कार बेहद स्पष्ट दिखाई देगी।
विशेष बात यह है कि भुवन वेबपोर्टल में दिखाई देने वाली तस्वीरें गूगल अर्थ से भी ज्यादा स्पष्ट दिखाई देंगी। इसमें शामिल तस्वीरों के लिए 10 मीटर रिजॉल्यूशन लिया गया है, बल्कि ऐसी सेवा देना वाली अन्य सेवाओं में 200 मीटर का रिजॉल्यूशन लिया गया है।
षड्यंत्रकारियों तक पहुँच: पिछले कुछ वर्षों में देश में हुए श्रृंखलाबद्ध बम धमाकों के बाद इसरो में भुवन जैसी प्रणाली तैयार करने की योजना बनी। यदि अब कोई षड्यंत्रकारी भुवन की सैटेलाइन तस्वीरों से धमाकों की योजना बनाएगा, तो उसे भुवन की टीम आसानी से ढूँढ निकालेगी।

गूगल अर्थ से बेहतर फोटो देखें भुवन पर नवभारत टाईम्स 12 Aug 2009
नई दिल्ली ।। इंडियन स्पेस रिसर्च ऑर्गनाइजेशन (इसरो) ने गूगल अर्थ के अपने देसी वर्जन की बुधवार को शुरुआत की। इस मैपिंग ऐप्लिकेशन में सैटलाइट इमेज डाली गई हैं। इनके जरिए यूजर दुनिया के किसी भी हिस्से को जूम करके नजदीक से देख सकता है। हालांकि संवेदनशील स्थलों को देखना सभी लोगों के लिए मुमकिन नहीं होगा। इसरो के चेयरमैन जी. माधवन नायर ने राजधानी में एक कार्यक्रम में भुवन वेबपोर्टल लॉन्च किया।
इसरो के एक अधिकारी ने बताया कि भुवन के जरिए देश के ज्यादातर हिस्सों को छह मीटर तक के रिजॉल्यूशन के साथ देखा जा सकेगा। ये गूगल अर्थ से अच्छी क्वॉलिटी की होंगी। इसमें जो तस्वीरें दिखेंगी, वह कम से कम एक साल पहले खींची गई होंगी। ये तस्वीरें काटोर्सेट-1 और काटोर्सेट-2 जैसे सैटलाइटों के जरिए खींची गई हैं। इन सैटलाइटों में लगे पावरफुल कैमरे सड़क पर चलती कार
के बराबर वस्तुओं की भी तस्वीरें खींच सकते हैं।

All about ISRO Bhuvan
Bhuvan, (Sanskrit: भुवन Hindi: भुवन, lit: Earth), is a satellite mapping tool similar to Google Earth and Wikimapia. It was developed by Indian Space Research Organisation (ISRO). It offers resolution up to 10 metres and is considered as a rival to Google Earth and Wikimapia.[1]
A prototype (beta)[2] of this application was launched on 12th August 2009.[3]

Overview
ISRO launched the beta version of its web-based 3-D satellite imagery tool, Bhuvan, on August 12, 2009. Bhuvan will offer superior imagery of Indian locations compared to other Virtual Globe software with spatial resolutions ranging from 10 m to 100 m. Locations can be viewed from different perspectives and will allow for the measurement of distances. The Bhuvan portal is designed to run on slow Internet connections. The imagery would steer clear of all sensitive military installations in India for security concerns.[4]
Bhuvan images of India along with a number of other interesting features which include weather information and even administrative boundaries of all states and districts, relevant only to the country. Bhuvan is equally capable of offering images of the globe, but the best resolution area includes India at the moment. In the Indian subcontinent, Bhuvan will be able to display a picture from ten meters away that is; a commuter moving on the road can be easily spotted.[5]
National Remote Sensing Agency played an important role in the creation of this product. ISRO has used data provided by satellites including Resourcesat-1, Cartosat-1 and Cartosat-2 to get the best possible imagery for India. ISRO claims that the application can provide imagery of up to 10 metres for major Indian cities compared to 200 meters provided by Google Earth.[6]
Bhuvan is based on TerraExplorer software a product of Skyline Software Systems [7].
Features
Bhuvan allows users to access, explore and visualize 2D and 3D image data along with rich thematic information on soil, wasteland, water resources etc in the Indian subcontinent.
It displays multi-resolution, multi-sensor, multi-temporal image data.
Users can superpose administrative boundaries of choice on images as required.
It allows visualization of AWS(Automatic Weather Stations) data in a graphic view and use tabular weather data of user choice .
Fly to locations (Enables users to fly from the current location directly to the selected location)
It features a Heads-Up Display(HUD) navigation controls (Tilt slider, north indicator, opacity, compass ring, zoom slider)
Allows navigation using the 3D view Pop-up menu (Fly-in, Fly out, jump in, jump around, view point)
3D Fly through (3D view to fly to locations, objects in the terrain, and navigate freely using the mouse or keyboard)
Drawing 2D objects (Text labels, polylines, polygons, rectangles, 2D arrows, circles, ellipse)
Drawing 3D Objects (placing of expressive 3D models, 3D polygons, boxes)
Snapshot creation (copies the 3D view to a floating window and allows to save to a external file)
Measurement tools (Horizontal distance, aerial distance, vertical distance, measure area)
Shadow Analysis (it sets the sun position based on the given time creating shadows and effects the lighting on the terrain)
There will be many more value added functions and facilities which will be added into the package from time to time. Particular interest of ISRO/DOS would be to provide such functionalities to common man so that they can adopt participatory approach with scientists to solve simple problems easily and interactively.
Some of the advanced functionalities to be provided in future versions:
Urban Design Tools (to build roads, junctions and traffic lights in an urban setting)
Contour map (Displays a colorized terrain map and contour lines)
Terrain profile (Displays the terrain elevation profile along a path)
Draw tools (Creates simple markers, free hand lines, urban designs)
Navigation map (to jump to and view locations in the 3D India)
