Chapter 4
MAPPING AND CANVASSING For the 2022 CAF, the conduct of canvassing an area of assignment and mapping is necessary to achieve the efficient implementation of the entire census field operation. In this chapter, you are required to learn how to read a barangay/EA/block map, conduct an ocular inspection of your assigned area, and carry out canvassing and mapping procedures to ensure complete coverage of your assigned area.
4.1 IMPORTANCE OF MAPS The completeness of census coverage depends highly on the accuracy and reliability of the maps that will be used during the census. The accuracy of the barangay and EA boundaries, the correctness of the orientation, and relative location of landmarks and other physical features on the maps will affect the coverage of the census. These important aspects should be ensured because maps are used not just in field operations but also in information dissemination, spatial analysis, and development and maintenance of the Master Sample Frame (MSF).
4.1.1 Census Maps For purposes of 2022 CAF, the pre-census barangay/EA/block maps will be used for the listing and enumeration. This was prepared by the Provincial Statistical Offices (PSOs) in collaboration with the Central Office based on the updated and processed maps used in 2020 Census of Population and Housing (CPH). As an enumerator, you will be given the following maps for canvassing, listing, and enumeration. These maps should be updated for new building points (3000 series) and destroyed/demolished building points on both paper maps and CAPI maps.
Barangay Map A barangay map is the graphical representation of the barangay covered for the 2020 CPH. Basically, it shows the general topographic features of the area, boundaries with adjacent barangays, and prominent landmarks and other area features.
Enumeration Area Map An enumeration area (EA) map is the graphical representation of a portion of the barangay covered for the 2022 CAF. If a barangay is subdivided into EAs, each EA map shows its boundaries with other EAs within the barangay.
Block Map A block map is the geographical representation of a portion of an EA covered for the 2022 CAF. If an EA is subdivided into smaller portions called blocks, each block map boundary shows its boundaries with other blocks within the EA.
