The plans of isolated land survey shall be drawn in which medium?

• A. Pencil
• B. Drawing ink
• C. Charcoal
• D. Marker

Answer: (B)

Plans of isolated land surveys are drawn in drawing ink because official survey plans must be permanent, legible, and easy to reproduce. Ink provides a durable, waterproof line that resists fading over time, which is essential for long-term archival storage and for making reliable copies. Surface materials like tracing paper or vellum hold ink well and allow clean, consistent lines that remain sharp when photographed or photocopied.

Pencil drawings are erasable and prone to smudging, which can compromise legibility and permanence. Charcoal also smudges and lacks the permanence required for official records. Markers can bleed and produce less precise lines, making them unsuitable for the meticulous detail needed in cadastral plans. Hence, drawing ink stands out as the standard for final, official plans.
