Fast, efficient land measurement without site visits
Total distance around boundary of a shape
Real distance = Photo measurement × Scale factor
Surface size of a shape in square units (e.g., m2m^2m2)
Shapes made from multiple simple shapes combined
V=A×hV = A \times hV=A×h (area × height/depth)
A≈w2(df+dl)A \approx \frac{w}{2}(d_f + d_l)A≈2w(df+dl)
Estimating area of irregular shapes with parallel sides
Gives approximation, not exact answer
1:x format (e.g., 1:1613 or 1:3500)
