2. Create a new shapefile file with polygon type with coordinates
the same as according to the frame, namely WGS 1984 UTM Zone 49S.
3. Polygons are made on each alignment area according to land use
on the line.
4. Right click on the created shapefile then click open attribute
table and add fields.

5. Determine the area of the polygon by right-clicking on the created field
then click calculate geometry. Select units of ha for area
