For coordinates 14°49'N and 120°54'E, what is the cadastral number of the Sectional Cadastral Map with a scale of 1:500 at the top left for Sector 1-B?

The key idea is how sectional cadastral map identifiers encode location and the quadrant of the sheet. When a map is oriented with north at the top, the top-left corner corresponds to the northwest quadrant. The coordinates 14°49'N and 120°54'E pin the exact location, and sec.1-B identifies the sector and subdivision. Since the instruction specifies the top left, the appropriate quadrant code is NW. The scale of 1:500 doesn’t change which quadrant is at the top left; it just indicates the level of detail on the map. Therefore, the cadastral number should end with NW, giving CM 14°49'N-120°54'E sec.1-B-NW.
