In this section, you will look at calculating:

• Elevation Profile of Line Annotation

• Surface Area of Polygon Annotation

• Volume of Polygon Annotation

Calculating Elevation Profile of Line Annotation

An elevation profile is a graphical representation that portrays a cross-sectional view of a terrain in a two-dimensional format, showing the changes in height along a line that connects selected points on a map.

1. Select the Line Annotation for which you want to calculate the elevation profile.

2. In the pop-up that is displayed, click Calculate Elevation Profile.

Calculating Elevation Profile

1. In the Token Quotation pop-up, click ACCEPT. The elevation profile is calculated and displayed as a graph.

Elevation Profile Graph

1. To download the elevation profile, click Download CSV.

Calculating Surface Area of Polygon Annotation

Calculating surface area is an important aspect of landscape pattern analysis, as it accounts for the non-uniform topography of a landscape.

1. Select the Polygon Annotation for which you want to calculate the surface area.

2. In the pop-up that is displayed click Calculate Surface Area.

Calculating the Surface Area

1. In the Token Quotation pop-up, click Accept. The Surface Area is calculated and displayed.

Surface Area Calculated

Calculating Volume of Polygon Annotation

The volume of the polygon is calculated in terms of Cut Volume and Fill Volume along with respective error margins. The Cut volume is the volume of structures (such as a stockpile) above the base elevation level and the Fill volume is the volume below the base elevation level.

1. Select the Polygon Annotation for which you want to calculate the volume.

2. In the pop-up that is displayed, click Calculate Volume.

Calculating Volume

1. In the Token Quotation pop-up, click Accept.

2. Select the Base Plane as Default or Custom. The cut and fill volumes will be calculated according to the base level selected.

Selecting the Base Plane

1. If you select the base plane as custom, enter or select the elevation in meters. The value entered here will be considered as the base and the cut and fill volumes will be calculated according to this base elevation level.

Select Elevation for Custom Base Plane

1. Click Initiate Volume Calculation. The calculated volume is displayed in terms of Cut Volume and Fill Volume along with respective error margins.
