G&S Project- Pakistan Glacier Inventory v.1.0

This new Pakistan glacier inventory has been extracted from optical data acquired by the European Space Agency Sentinel-2 twin satellites. This choice is dictated by the need to respond to the requirement to have homogeneous coverage of the entire territory under examination in terms of image acquisition dates, cloud cover and good spatial resolution, that allow the recognition of glaciers and their mapping. Furthermore, particular attention in the selection of the data processing and mapping methods was given for the expected prospect activity of updating the glacial perimeters and monitoring changes in the future.

The methodology was based on a semi-automatic classification (segmentation) and the mapping has been implemented in a Geographic Information System (GIS) environment.

In this new inventory, 13,032 glaciers covering 13,546.93 km2 have been mapped.

The available inventory is the Version 1.0.

Supplemental Information

You can customize the template to suit your needs.

You can add

and remove fields and fill out default information (e.g. contact

details).

Fields you can not change in the default view may be accessible in the

comprehensive (and more complex) advanced view. You can even use the

XML editor

to create custom structures, but they have to be validated by the

system, so

know what you do :-)

Statement

This Pakistan Glacier Inventory has been extracted from ESA Sentinel2 data acquired on 2022. The workflow in the applied procedure is composed by three main steps:

 Satellite data acquisition and composite;

 Spectral Index extraction;

 Data classification and segmentation.

The time series of Sentinel-2 L1C data in the acquisition period from "2022-07-31" to "2022-10-01" was processed. The resulting image composite is a cloud free Sentinel-2 multiband dataset, time-centered at the end of August.
