5.09 Metadata for Local Government Units

Local Government Units
Region - A sub-national administrative unit comprising of several provinces having more or less homogenous characteristics, such as ethnic origin of inhabitants, dialect spoken, agricultural produce, etc. MAP

Province - The largest unit in the political structure of the Philippines. It consists, in varying numbers, of municipalities and, in some cases, of component cities. Its functions and duties in relation to its components cities and municipalities are generally coordinative and supervisory.

City - There are three classes of cities in the Philippines: the highly urbanized, the independent component cities which are independent of the province, and the component cities which are part of the provinces where they are located and subject to their administrative supervision, (see City Classification)

Municipality - Is a political corporate body, which is endowed with the facilities of a municipal corporation, exercised by and through the municipal government in conformity with law. It is a subsidiary of the province, which consists of a number of barangays within its territorial boundaries, one of which is the seat government found at the town proper (poblacion).

Barangay - The smallest political unit into which cities and municipalities in the Philippines are divided. It is the basic unit of the Philippine political system. It consists of less than 1,000 inhabitants residing within the territorial limit of a city or municipality and administered by a set of elective officials, headed by a chairman (punong barangay).

Urban/Rural Classification
In the Philippines, "urban" areas fall under the following categories:

  1. In their entirety, all municipal jurisdictions which, whether designated chartered cities, provincial capital or not, have a population density of at least 1,000 persons per square kilometer: all barangays;
  2. Poblaciones or central districts of municipalities and cities, which have a population density of at person’s square kilometer;
  3. Poblaciones or central districts not included in (1) and (2) regardless of the population size which following:
    1. Street pattern or network of streets in either parallel or right angel orientation;
    2. At least six establishments (commercial, manufacturing, recreational and/or personal services);
    3. At least three of the following:
      1. a town hall, church or chapel with religious service at least once a month;
      2. a public plaza, park or cemetery;
      3. a market place, or building, where trading activities are carried on at least;
      4. a public building, like a school, hospital, puericulture and health center or library.
  4. Barangays having at least 1,000 inhabitants, which meet the conditions, set forth in (3) above and where the occupation of the inhabitants is predominantly non-farming or fishing.

Rural Areas - All poblaciones or central districts and all barrios that do not meet the requirements for classification of urban.

City Classification
Highly Urbanized Cities - Cities with a minimum population of two hundred thousand (200,000) inhabitants, as certified by the National Statistics Office, and with the latest annual income of at least fifty Million Pesos (P50,000,000.00) based on 1991 constant prices, as certified by the city treasurer.

Independent Component Cities - Cities whose charters prohibit their voters from voting for provincial elective officials. Independent component cities shall be independent of the province.

Component Cities - Cities, which do not meet the above requirements, shall be considered components cities of the province in which they are geographically located. If a component city is located within the boundaries of two (2) or more provinces, such city shall be considered a component of the province, which it used to be a municipality.

5.09.01 Structure of the Philippine Standard Geographic Code (PSGC)

Inter-Level Codes

  1. Region Code – This is a two-digit code number that identifies a specific region. It ranges from 01 to 99. Generally, the Region Code corresponds to the Region number (e.g., Region Code 01 refers to Region 1, 02 refers to Region 2, etc.)

  2. Province Code – This is a two-digit code number that identifies the province. It ranges from 01 to 99, generally defining the relative alphabetic sequence of all provinces in the country except those created after 1977 which were added to the list following the updating procedures in Section 2.2.2. A Province Code is independent from a Region Code. This means that even if the province is transferred to another region, its Province Code remains the same.

  3. Municipality Code – This is a two-digit code that generally defines the relative alphabetical sequence of the municipalities within the province. It ranges from 01 to 99. Municipality Code 01 means it is the first municipality in alphabetical sequence within that province. The Municipality Code is dependent upon the Province Code to fully establish the identity of municipality. This two-digit code is used to identify the municipalities, cities or municipal districts in a particular province. In the case of the first regional district (City of Manila) of Metropolitan Manila Area (National Capital Region), the fourteen city districts of the City of Manila are treated as municipalities.

  4. Barangay Code – This is a three-digit code number which generally defines the relative alphabetical sequence of the barangays within the municipality. The code ranges from 001 to 999. Barangay Code 010 means it is the 10th barangay in alphabetical4 sequence within that municipality. The Barangay Code is dependent upon the Municipality Identifier to fully establish the identity of a given barangay.

Municipality Identifier
The Municipality Identifier is the core of the national standard geographic classification system. This is composed of the Province Code followed by the Municipality Code. The Municipality Identifier is a four-digit number that defines the identity of the municipality.

The municipality Identifier 7310. The first two-digits 73 is the Province Code for the province of Zamboanga del Sur. The last two-digits 10 is the Municipality Code. This means that it is the 10th municipality within the province of Zamboanga del Sur, which in this instance is Kabasalan. The Municipality Identifier 7310 would therefore define Kabasalan, Zamboanga del Sur.

Continuous addition of newly created barangays as a result of periodic updating resulted in the discontinuous alphabetic arrangement of barangays in the later portion of the list.

Municipality Code Dependent on Province Code
It will be noted from the above illustration that the Municipality Code only provides for the relative alphabetical sequence of the municipality within the province (e.g. 1st, 2nd, 3rd, etc.). By itself it is not sufficient to define the municipality. However, when the same is attached to the Province Code, it acquires a unique meaning. For the Municipality Identifier 7310, there is only one municipality within Zamboanga del Sur whose code is 10, and this is the municipality of Kabasalan. Hence, the Municipality Identifier (Province Code and Municipality Code) defines the unique identity of the Municipality.

Municipality Identifier Independent of Region Code
As has been pointed out, the Municipality Identifier not only identifies the municipality but also the province to which it belongs. An added feature of the Municipality Identifier is its independence from the Region Code. Regardless of the Region, the Municipality Identifier for Kabasalan will remain 7310 as long as it is part of Zamboanga del Sur.

Barangay Identifier
Barangay Identifier 7310001. The first four digits 7310 is the Municipality Identifier as fully explained in section 4.2. The last three digits 001 is the Barangay Code which refers to the first barangay within the municipality with Municipality Identifier 7310. Barangay Code 001, in this case, refers to Barangay Balongis. Thus, Barangay Identifier 7310001 means Barangay Balongis in Kabasalan, Zamboanga del Sur.

Barangay Code Dependent on Municipality Identifier. The Barangay Code only provides for the relative alphabetical sequence of the barangays in the municipality. Barangay Code 001 means it is the first barangay in the alphabetical sequence. By itself the Barangay Code is not sufficient to define the identity of the barangay. However, when the Barangay Code is attached to a Municipality Identifier, the result is a unique code which fully establishes the identity of the barangay. In Barangay Identifier 7310001 there is only one barangay in the entire Philippines with such code number, and that is Barangay Balongis in Kabasalan, Zamboanga del Sur.

Hierarchy of Recapitulation
(09) - 7310-001 : Barangay Identifier, with Region Code prefixed. This gives the details on the barangay level. By definition, the aggregate of all barangays in a municipality defines the municipality.

(09) - 7310 : Municipality Identifier, with Region Code prefixed. This gives the details on the municipality level. The aggregate of all municipalities defines the province.

0973 : Region and Province Code. This is the recapitulation of details by province, within each region.

Agency Unique Requirement
The Philippine Standard Geographic Code establishes standardization for the following: Region, Province, Municipality and Barangay. This however, does not preclude an agency from devising additional sub-categorization on geographic area units geared purely to its operational functions to meet its unique requirements.

A good case in point here is the unique requirement of National Statistics Office (NSO) in statistical surveying functions. In addition to the Region, Province, Municipality and Barangay Code, it needs additional coding for the Enumeration District (ED) as well as rural and urban classification. This is purely a unique requirement of the NSO to monitor and enhance its survey operations. Other agencies may have similar unique requirements.

In order to effect standardization and at the same time be responsive to the unique operational requirements of an agency, the following guidance was established:

  1. The whole string of digits representing the Region Code, the Province Code, the Municipality Code, and the Barangay Code shall remain standardized for all agencies in the government. The sequence in the code structure must be maintained as standardized.

  2. Any other unique code that may be devised by an agency could be added to the basic standard geographic code, provided the structure of the standard geographic code is not altered.

  3. he concerned agency should inform the Code Administrator of the PSGC of any unique code application.

5.10.01 AA Paper Format Dimension

Fig. 1. Dimension of AA paper sizes with respect to each other.Fig. 1. Dimension of AA paper sizes with respect to each other.

The ISO A Series paper size is widely used all over the world today. We know them as paper sizes like A4 and A3 which are common and the larger sizes A2, A1 and A0. It is base on the International Standards Organization ISO 216

ISO 216 defines the A series of paper sizes based on these simple principles:

  1. The height divided by the width of all formats is the square root of two (1.4142).
  2. Format A0 has an area of one square meter.
  3. Format A3 is A2 cut into two equal pieces. In other words, the height of A3 is the width of A2 and the width of A3 is half the height of A2.

  4. All smaller A series formats are defined in the same way. If you cut format An parallel to its shorter side into two equal pieces of paper, these will have format A(n+1).

The standardized height and width of the paper formats is a rounded number of millimeters.


Fig. 2. Example of an A3 map with suggested dimensions.Fig. 2. Example of an A3 map with suggested dimensions.

Dimensions above be converted into the next bigger paper size (A2) by multiplying the value by the square root of 2 (1.4142). Ex. The right margin of 1.25 cm in A3 will be 1.76 cm in A2 (1.25 cm X 1.4142).

Step 1. Fold the paper map (A3) into two (2) equal halves as shown in Fig. 3.

5.10.02 Map Scales Projection

One of the activities of the Inter-Agency Task Force on Geographic Information (IATFGI) is to develop and recommend minimum standards for Geographic Information System interchange, and standard methodologies and concepts and definition for universal adoption by all government agencies in the generation of geographic information.

The function/task of the IATFGI and its Technical Working Group are to come up with standards or at least an agreement with member agencies on the scales of maps and the type of map projection to be used by each agency.

It was observed that when integrating and overlaying data from maps of different agencies, it was always a difficulty doing spatial analysis since most of the maps used are of different scales much more if the maps produced were compiled using different projections.

With the availability of computer techniques to handle reducing and enlarging of maps, the above is not much of a problem these days. However, paper continues to play a role in modern mapmaking. Mapping institutions that have evolved from paper-based- to digital-based mapping face a dual problem; how to create new maps electronically, and how to convert existing maps into compatible electronic formats. Also, map related projects may involve a mixture of new electronic data as well as legacy data stored on paper, forcing the user to put together mapped information from different sources.

Recommended Solution
It is the intention of IATFGI to come up with agreed map scales to ease up overlaying procedures. The following table shows the map scales to be used both for central and local government as well as the private sector:

Table 0

The scale of the map should permit representation of needed details with reasonable precision. The size or positioning of the smallest detail should fall within the allowable accuracy of the map (i.e. 0.2 mm for X and Y/planimetric coordinates at map scale at the smallest and thinnest line that can be plotted in the map, and 1/3 the contour interval in Z/elevation coordinates). As an example, a 1:10,000 map has an accuracy of 2.00 meters in X and Y ground coordinates and 3.00 meters in elevation (if contour interval is 10.00 meters). This means that a feature may have an allowable error of 2 meters in X and Y and 3 meters in Z from its exact position.

Table 1

Map Projection
In the production of the maps, the Transverse Mercator Projection shall be used except for maps at scales 1:1,500,000 which is in a Conical Projection where the reference latitude will be the equator (lat 0 ).

The Universal Transverse Mercator (UTM) projection shall be used for all maps with scales smaller and equal to 1:10,000.

To abide with the DENR Administrative Order No. 72-1 Series of 1990, a pair of Philippine Transverse Mercator (PTM) lines shall be shown on topographic maps to aid local surveyors and other users familiar with the use of the Philippines. Only the maps of PALAWAN at scales 1:250,000 shall use Zone 50 (117), the rest will be Zone 51 (123).

Table 2

For maps on scales larger than 1:10,000, this system (PPCS) shall remain to be used. These maps shall follow the specifications stated in the Manual for Land Surveys in the Philippines (Lands Administrative Order No. 4 dated 3 July 1980).

Table 3

In cases where it cannot be ascertain to which zone 1he map is to be projected or the area traverses two zones, then as a rule of thumb, the zone with the largest area will be the deciding or dominant zone is to be used.

The assignment of provinces into the map projection zones of the PPCS shall be as follows:
