The resolution of a satellite image means the smallest size of an object or detail that can be represented in the image. The higher the resolution, the smaller the pixel size which means a much more detailed image. Consider the following about Very High Resolution (VHR) Satellite Imagery.

1.It offers sub-centimetre resolution.

2.Any type of vehicles on road can be identified using VHR imagery.

3.Structural changes of landscapes can be easily monitored with this imagery.

Explanation:

It offers sub-meter resolution – one of the highest image qualities currently available from commercial remote sensing satellites.
Sub-meter (VHR) resolution satellites offer users a smaller ground sampling distance (GSD)
Than other imaging satellites, making them more suitable for reliable natural or man-made, objects and landscapes observation, site monitoring, object identification and many other tasks requiring precision data.
Among its many advantages, VHR images enable the identification of specific models of vehicles, vessels and airplanes, as well as the monitoring of structural changes, natural disasters, industrial operations and livestock.
This versatility makes EROS imagery a powerful resource for both civilian and military needs. This versatility makes VHR imagery a powerful resource to Government officials, which can be integrated for variety of activities.
Recently Forest Survey of India (FSI) acquired VHR data from SkyMap Global through NRSC for forest areas of Karnataka and Maharashtra.
An application has developed which allow users to visualize VHR images and other datasets
