Note: This Information Product is a first attempt to provide guidance in preparing the information needed for the CLUP. As more knowledge is gathered, the IP will be updated. Likewise, updates may be required due to new or changing land-use policies. Furthermore, data will continuously be prepared by the custodians, which may require updates.

	Step 1: Provide a Background and Identify the Objectives of the GIS Analysis
	The safety of the community is a prime consideration in determining the location of future settlements in a locality. It is important therefore, that the susceptibility of an area to flooding be taken in consideration not only in determining future urban areas but also finding solutions to the problem of flooding. Moreover, as planners of municipalities/cities where hazards are inevitable, disaster risk management should be considered in all planning endeavors.
	The main consideration in this example is to determine the location of areas susceptible to flooding which will be given consideration in the GIS analysis to determine suitable sites for urban use, in order to avoid flooding disasters.
	Step 2: Identify the Areas to Determine Location of Flooded Areas
	Indicators are: Flooded and non- flooded areas as seen on the map provided by the MGB geohazard map. PAGASA prepares flooding maps based on meteorology or rainfall. In the future, Hazard maps will be harmonized as there is an ongoing harmonization project for these agencies together with the Phivolcs and NDCC.
	Step 3: Create the Database
	Attribute
	The following attribute table was used for this example. EM03 Flood
	Spatial
	The object flood prone areas will be a polygon.
	The image below is a Geohazard map from the MGB. The scanned map will serve as the background when digitizing the flooded areas. Ultimately, residents in the community should also be consulted as they are the most likely persons to know where and when flooding occurs.
	Geohazard image
	Below is a digitized map of flooded areas using MGB geohazard map and other map sources.
	Step 4: Analyze the Data
	The digitized flooding map will be useful when alternative spatial strategies are drawn out in coming up with the proposed Land Use Plan as it will be an input when identifying suitable areas for urban expansion.
	Step 5: Present the Data
	Likewise, this information will in the future be most useful especially when preparing an “Awareness and Preparedness Plan” or the Rehabilitation Plan for areas struck by disasters as well as for flood control purposes. Ultimately, the flooding map data is important for planning for the locations of residential areas.
