The newscard has information on Cartosat 2E developed by ISRO. Here are a few takeaways from this newscard

Prelims Level: Note down about Cartosat- 2E, its advantages.

Mains Level: Not very Mains heavy newscard


1. A railway station in Rajasthan and eye-catching locations in Qatar and Egypt are among the early pictures beamed down by the week-old Cartosat-2 series spacecraft

What is Cartosat- 2E?

1. It is the third Indian remote sensing (IRS) or earth observation satellite that can send 60-cm resolution pictures from an orbit 500 km above the earth

2. Cartosat-2E is the sixth and last of the second generation cartography themed series, which started in 2007

Advantages of Cartosat- 2E

1. It will provide useful space-based data for town planners, creators of urban infrastructure

2. It will gather information for agriculture and project monitoring

3. It will collect relevant information for decision makers in Smart City and AMRUTH projects

4. Availability of high-resolution Cartosat-2E data to civil agencies would drive down import of remote sensing imageries from foreign EO satellites

Why were images imported?

1. Imageries had to be imported because Indian EOs offered only 1-metre resolution pictures

2. Now there is the sub-metre availability which will make a significant impact
