About HGIS

The information system comprises of 4 major functions

1. Display feature for basic layers and selected layers. Some of the basic glacier layers are

• Basin boundary

• Sub-basin Boundary

• International Boundary (not authenticated)

• Glacier Outlines (having Glacier Data Sheet attached as attributes)

• Glacier Morphology Layer

• Glacier Snout

• Glacier Centre Line

2. Smart Filter permits multiple querying on the glacier information within a Basin (Indus, Ganga and Bramhaputra) or any of the 55 Sub-basins.

• Identification number (twelve digits e.g. IN5053M04012)

• Dimension (Area: Glacier total area, Length: Glacier Total length, Ablation length, Mean glacier length and Width: glacier ablation mean width)

• Orientation (Eight direction scale viz. E,W, N, S, NE, NW, SE, SW)

• Elevation (Snout elevation, Snow line elevation, Highest elevation, Mean elevation of glacier

• Classification (Primary Classification and Form)

• Date (Snow line date /satellite pass date1 and satellite pass date 2)

3. Graph generation

• Interactive graph generation based on selected glacier features

4. Map Composition and Printing

The glacier features can be interactively displayed on the monitor and can also be saved as image file. The image file can be printed by using the print icon.
