摘要：

To leverage Geospatial data and technologies for monitoring and managing the planet’s green cover, in line with the Sustainable Development Goals for life on land (SDG 15) and climate action (SDG 13). An application was developed for vegetation monitoring derives data from the Indian Remote Sensing Satellites and archives them. The data includes vegetation indices, soil moisture, temperature throughout the field, rainfall and other such parameters which are continuously archived by the application. Data from a freely available foreign satellite are also used. The application facilitates interactive visualization and analytics on the web. The repository of multi-temporal (over 22 years) and multi-resolution (500 to 10 m) NDVI time series data is available on VEDAS (https://vedas.sac.gov.in/vege- tation-monitoring/index.html). The website provides capabilities to perform several image processing operations such as image differencing, temporal classification, Geospatial query, principal component analysis, temporal NDVI compositing and long-term statistics. The application also supports the presentation of data such as heat maps, temporal profiles, and Year-on-Year (YoY) comparisons. Zonal statistics at the district, taluka and village levels are also supported.
