Circular 10/2015/TT-BTNMT stipulates that remote sensing image data must meet the technical parameters of the remote sensing image and the satellite's orbit. To be specific:

- Level 0 remote sensing data must ensure quality during the signal acquisition and processing, with no signal errors or interruptions.

- Level 0 remote sensing data must be preliminarily evaluated for cloud cover level in the form of quick view images. The classification of cloud cover is divided into levels and denoted by letters as follows:

- Level A: Remote sensing image with cloud cover below 10%;- Level B: Remote sensing image with cloud cover from 10 - 25%;- Level C: Remote sensing image with cloud cover 25% or more;

Remote sensing images selected as input data should have cloud cover appropriate to the requirements set by the user.

In addition, the Circular also specifies that maps used for identifying control points must be national digital topographic maps at a larger scale than the remote sensing image map being established.

The data required to be collected for remote sensing image production includes:

- Remote sensing image data.- Map data.- Image control point data.- Digital elevation model.- Project technical design and other relevant technical documents.

For more details, refer to Circular 10/2015/TT-BTNMT, effective from May 12, 2015.
