Topographic Maps

Topographic maps are graphic representations of the earth’s natural and man-made features. The shape and elevation of the terrain are portrayed in them. Elevation is expressed in a 100-meter contour line interval.

These maps are fundamental tools for planning, researchers, and studies. These are used as base maps and form an essential part in the preparation of other kinds of thematic maps.

NAMRIA produces maps in different scales.

The Philippine topographic maps at scale 1:250,000 were produced with information from the Philippine Coast and Geodetic Survey, Army Map Service, Corps of Engineer, US Coast and Geodetic Survey, Bureau of Public Highways, and other agencies. These maps are downloadable and can be printed on an 8 x 11.5 inch bond paper.

The Map 711 series at scale 1:50,000 was originally published by the US Army Service and was compiled from aerial photographs taken in 1947-1953. It was replaced by the Map 701 series which was produced using aerial photographs taken in 1979. It only covers the Luzon island, however.

The NTMS at scale 1:50,000 is starting to replace both S711 and S701 maps. It covers the whole Philippines in 672 sheets. Maps are in 15' x 15' interval. Elevation is expressed in 20-meter contour line interval.

Topographic maps at 1:10,000 scale were produced using the aerial photographs taken in 1982. It covers an approximate area of 1,500 sq. km. encompassing the whole Metro Manila and the adjoining provinces. Also available are 22 maps covering Ilocos Norte, La Union, Baguio City, Subic, Legaspi City and Zamboanga City.

The 1:5,000 scale map is the largest topographic map scale we have produced. This covers the urban areas of Bacolod City, Iligan City, Metro Iloilo, Metro Cebu, and Cagayan de Oro.

We also have planimetric and land condition maps at 1:10,000 and 1:100,000 scale; land condition maps at 1:10,000 scale; and land cover maps at 1:250,000 scale.

note: Inquire at the NAMRIA Information Center or at the MSOs regarding the availability of these maps and for further information.
