Resources
All downloadable files are either in .pdf, .jpg, or in .zip format and you may need specific file viewers for these.

Some of the map downloads are low resolution images and can only be printed on letter size papers. Other map downloads are high resolution images such as topographic maps in 1:50,000 scale and hazard maps.

Topo Maps 1:250,000 Scale
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.

Below is an index map for topographic maps at scale 1:250,000. Click on the boxes to view map sheet thumbnails.

Topo Maps 1:50,000 Scale
The maps in the 711 series at scale 1:50,000 were originally published by the US Army Service and were compiled from aerial photographs taken from 1947 to 1953. The series 711 maps were replaced by the maps of 701 series. The 701 series was produced using aerial photographs taken in 1979 and only covers the Luzon island.

The NTMS maps at scale 1:50,000 replaces both S711 and S701 maps. It covers the whole Philippines in 672 sheets. The NTMS maps are in 15' x 15' interval and elevation are expressed in 20-meter contour line intervals.

Hazard Maps
The READY Project is a collaborative effort of the Government of the Republic of the Philippines, the United Nations Development Program (UNDP) and the Government of Australia Australian Aid (AusAID).

It aims to address the problem of disaster risk management at the local level by empowering the most vulnerable municipalities and cities in the country and enable them to undertake disaster risk management. The project hopes to develop a systematic approach to community based disaster risk management in 27 identified high risk Philippine provinces.

The Office of Civil Defense (OCD) is the executing agency of the Project while the collaborating National Disaster Coordinating Council (NDCC) agencies are the Mines and Geosciences Bureau (MGB), the National Mapping and Resource Information Authority (NAMRIA), the Philippine Institute of Volcanology and Seismology (PHIVOLCS-DOST), and the Philippine Atmospheric, Geophysical, Astronomical and Services Administration (PAGASA-DOST).

Flood Extent Maps - Areas affected by Typhoon Ulysses
The flood extent of Cagayan and Isabela Provinces was generated from Sentinel-1 radar imagery (Copernicus Open Access Hub). The imagery used was taken before (20 October 2020) and during (13 November 2020) the Typhoon Ulysses flood event. Using SNAP software from European Space Agency (ESA), the data was processed through the application of threshold method to derive the extent of flooding. The results are preliminary and subject to ground validation. The administrative boundaries are approximate.
The flood maps (below) were generated based on the flood heights gathered from actual measurements of flood depths and in-person interviews conducted by NAMRIA from November 18 to 20, 2020 after the onslaught of Typhoon Ulysses (I.N. “Vamco”). The areas covered are Marikina City, and the municipalities of Cainta, San Mateo, and Rodriguez in the province of Rizal. Because of flood debris and clearing operations during the data gathering period, not all flooded areas were surveyed. The flood water extents were then generated by interpolating flood point heights using inverse distance weighing (IDW) method.
