Data Sets
Open source data sources have revolutionized the world of Geographic Information Systems (GIS) and Remote Sensing (RS) by making geographic and spatial information accessible. These freely available datasets cover a wide range of topics, from land use and transportation to environmental variables, making them invaluable for a multitude of applications. Here is a list of open data sources:
PRADAN- web application developed by ISSDC
PRADAN is a web application developed by ISSDC , ISRO. Users are required to register and login for Chandrayaan-2 Orbiter imaging payload data download.
It provides single sign-on (SSO) feature for all data sets hosted on PRADAN, i.e. once the user logs-in to access any of the data sets, all other data sets hosted on PRADAN also become accessible without requiring user to re-enter the login credentials. PRADAN stands for Policy based data Retrieval, Analytics, Dissemination And Notification system
NASA's Common Metadata Repository (CMR)
This expansion, combined with the wealth of open datasets on cloud computing platforms and the STAC Index, make it easier than ever to leverage these datasets for a wide range of applications, from Earth observation to environmental monitoring.
It can be accessed via
