3D Building Data For Major Indian Cities
Fly to any part of India. Locate buildings, business- centre, terrain in 3D. Navigate through the streets as you actually do. Search addresses, places of your interest across the major cities of India on a click of a mouse.

Various industries are utilizing these 3D Maps to optimize their businesses. Telecom is one such sector  wants to utilize this advanced technology to establish its network of antennas. Annova Technologies is involved in providing 3D Maps consisting of 3D Building databases of major cities of India. These 3D building model datasets are integrated with several basic layers defining the terrain elevation with a resolution and accuracy of one meter of the project area. With the help of these virtual city models of various cities, telecom majors are able to simulate and conduct RF (radio frequency) planning and analyze the line of sight visibility between antennas, the interference between antennas, and the reflections and refraction from building surfaces and edges. Our low cost yet one-meter accurate 3D buildings database provides an appropriate approximation of the urban setting is the best compromise between detail and price.

Sikkim Earthquake
Nature's fury has always been the cause of mass destruction since time in memorial and Man's quest for minimizing the destruction caused by such agents continues...
Another such event (Sikkim Earthquake) occurred which resulted in deaths of more than 100 people with several missing. Even in this era of scientific advancements, predicting an earthquake in time, is a major challenge for scientific community. Sikkim Earthquake (of 6.9 magnitude on the Richter Scale), centered within the Kanchenjunga Conservation Area, near the border of Nepal and the Indian state of Sikkim occurred on 18th September. 2011. Several buildings collapsed in Gangtok.

A detailed study was carried out by National Remote Sensing Centre (NRSC), Hyderabad, India on the pre and post- satellite imagery (Optical and Microwave) of the earthquake. Optical data received within 24 hours were covered with cloud. The latest cloud free IRS data sets (of 29th and 30th September, 2011) were used for analysis and mapping the landslides which occurred after the event.
354 new landslides were mapped using pre and post CARTOSAT-1 stereo data sets.

India carries out Tsunami Warning System Test
India, along with 20 Indian Ocean Nations, participated in Mock Tsunami Drill (Exercise IOWave) on 12th October, 2011 aimed at testing the Indian Ocean Tsunami Warning and Mitigation System (IOTWS). The drill was organised under the auspices of UNESCO’s Intergovernmental Oceanographic Commission. The Regional Tsunami Advisory Service Providers (RTSPs) of the region for Tsunami Warning System are India, Australia, Indonesia.

The drill was aimed to evaluate the system’s operational capacity, the efficiency of communications among the different concerned actors, and the state of preparation of national emergency services.The test also included the evacuation of coastal communities in several countries (notably, India and Malaysia). INCOIS Hyderabad would act as IOWTS centre or RTSP for India. All the RTSPs of the region would take over the responsibility of providing tsunami bulletins to Indian Ocean member countries, which currently are provided by Pacific Tsunami Warning Centre (PTWC) & Japan Meteorological Agency (JMA) (till 2012). Exercise IOWAVE 11 re-enacted the events of 26 December 2004, with a 9.2 magnitude earthquake off the North West coast of Sumatra (Indonesia), followed by an ocean-wide tsunami. The simulated wave crossed the Indian Ocean in 12 hours to strike the coast of South Africa. The drill also included evacuation of coastal communities.
