In order to create an inventory of coastal resources in this project, it is necessary to continuously collect secondary data aside from the primary data acquired from LiDAR surveys. While waiting for LiDAR data sets, the CoastMap Component collected secondary data from various government agencies, local government units, and from nongovernment organizations. This has been facilitated by arranging various meetings with representatives from these agencies and organizations and from the Regional Development Council as pointed out earlier in this report.


  Secondary Data Collection


            A search for available online and offline databases was carried out. We found few existing databases on the coastal resources of the entire country. Attached to this report are the databases that were downloaded and requested from various institutions. It should be noted that the institutions we emailed for the request requires us to use the dataset for non-commercial purposes only. The databases were collected from the following sites: Global Administrative Areas (GADM version 2) at; Ocean Data Viewer at; Philippine GIS Data Clearinghouse (PhilGIS) at; The Coral Triangle Atlas (CT Atlas) at So far, the following databases were collected: [1] sites where coral bleaching occurred; [2] sites where coral diseases were reported; [3] marine protected areas; [4] reef locations; [5] seaports; [6] bathymetric data; [7] mangrove areas; [8] seagrasses. It should be noted that the metadata accompanying the databases are not very informative and there is a need to know the geographic coordinate system that the various databases were using.


            Sample maps showing coral reefs, mangrove forest coverage, marine protected areas, and coastal bathymetry are shown in Figure 6.1, Figure 6.2, Figure 6.3, and Figure 6.4, respectively. Figure 6.5 shows the mangrove forest cover and fishponds in Bohol and Figure 6.6 is the same as Figure 6.1 except that buildup areas (areas with increasing demographics) are included. It can be seen that among the provinces in Central Visayas, Bohol is the most ecologically stable in terms of marine resources and the number of marine protected areas. Although more urbanized as can be seen in the number and size of buildup areas in Figure 6.6, Cebu generally has considerable marine/coastal resources and has relatively stable marine environment due to its relatively high number of marine protected areas (second to Bohol).


           Extensive information on the use of GIS in government reports also exist. For example, a NEDA 7 report on the Regional Physical Framework Plan (RPFP) covering a time horizon from 2003-2030 made extensive use of GIS generated map to convey information to its readers (i.e., politicians, bureaucrats). Similarly, the figures of another NEDA 7 report the Central Visayas Isle Ecotourism Development Plan 2012-2016 made extensive use of GIS maps. The coastal environmental profiles of the learning sites (Green et al., 2002; Christie et al., 2006; Yambao et al., 2001; Green et al., 2000; Sotto et al., 2001; Green et al., 2004) of the USAID-funded CRMP (Coastal Resource Management Program) of the DENR also extensively produce coastal habitat (GIS-based) maps. However, the data were point-based & spatial analyses were probably limited. However, one example in really using the available database is the article by Weeks et al. (2009) which compiled MPA data from different sources (i.e., NGOs, academes in the Philippines, UNEP global protected area databases (WCMC 2007), MPA Global (Wood 2007), peer reviewed and gray literatures) into a new geodatabase of Philippine MPAs using ArcGIS.
