Once a project is created, the project area will be shown in this light blue color. COI can only be drawn within this area. If the COI is outside of the project boundary, it won't be saved. We use the draw tool and the remove tool on the toolbar to draw COI and remove COI.

Draw COI

Click the draw tool and then start drawing a polygon on the map. Double click to close the polygon.

After the polygon is closed, click somewhere else on the map to show the attribute window and type COI description information.

Show COI Attributes

By default, the COI attributes are not shown. You can click the button at the bottom right corner to open the COI attribute table. When a COI is saved, the user who creates this COI and the time when this COI is created will be recorded.

Draw COI

Click the COI you would like to edit, when the cursor becomes cross cursor, we can either move the whole COI polygon or drag the location of each point to change the shape of this COI.

Delete COI

Click the COI you would like to delete, and then click the delete button on the toolbar. This COI will be removed.
