  3. 3. Our Vision Indian space programme driven by vision of Dr Vikram Sarabhai, the father of the Indian Space Programme“There are some who question the relevance of space activitiesin a developing nation. To us, there is no ambiguity of purpose.We do not have the fantasy of competing with the economicallyadvanced nations in the exploration of the moon or the planetsor manned space-flight. But we are convinced that if we are toplay a meaningful role nationally, and in the community ofnations, we must be second to none in the application ofadvanced technologies to the real problems of man andsociety.”

  22. 22. SOIL MAPPING AT VARIOUS SCALES Over the years, remotely sensed data like Landsat-MSS / TM , SPOT and IRS - LISS-I, II, III, IV etc., were employed to map soils at different scales ranging from 1:250,000 scale to 1:50,000 scale and even to 1: 12,500 scale.Small NBSS&LUP mapped soils of entire country using Less Landsat MSS / TM data on 1: 250,000 scale. Under IMSD Project, soils were mapped at 1:50,000 scale using IRS-LISS-II/ Landsat-TM data for various parts in Level of detail India covering an area of about 83.3 million hectares. Scale Under NATP soil maps at 1:12,500 scale were prepared for different micro-watersheds under different crop production systems /agro-climatic zones of the country. Under VRC programme, DOS is mapping soils on 1:10,000 or 1:8,000 scale using IRS-P6 LISS-IV and Cartosat data to provide soil resources information at village levelLarge More
