Ø  Open a box and fill it

Ø  Then ok

Ø  Right Click on hill shad layer and go to properties

Ø  Click on display and change transparency

Ø  Add new file bed_elev

Ø  Click on extract by mask

Ø  Then open a box and fill it

Ø  Click ok

Ø  Right click on extract bed_elev and go on properties

Ø  Click on display and change transparency

Ø  Click on symbology

Ø  Right click on color ramp and change the colour

Ø  Then click ok

Ø  Open raster calculator from Arc Toolbox

Ø  Open calculator box and apply the formula

Ø  Con(“clip_bed_elev”<=0,1)

Ø  Change the output raster from environment

Ø  Then click ok

Ø  Right Click on raster layer and go on properties

Ø  Click general and change name

Ø  Click on display and change transiency

Ø  Then click ok

Ø  Add a new layer ice_thick

Ø  Open surface volume from 3D analyst tools and click functional surface

Ø  Open a box and fill it

Ø  Then click ok

Ø  Right click on ice layer and click open table and see volume

Ø  Open raster calculator

Ø  Apply the formula on ice_thick

Ø  “Ice_thick”*0.2825

Ø  Change output raster

Ø  Then click ok

Ø  Again Open raster calculator

Ø  Apply the formula on “ADD_v3_vectors lyr\boundry_water”*0.2825

Ø  “ADD_v3_vectors lyr\boundry_water”*0.2825

Ø  Change output raster

Ø  Then click on ok

Ø  Now give the coordinate system and title on map and save image in JPEG format.
