Geographic features of streets, bridges, and water bodies with topology6
- A set of vector data7 of streets, bridges, and water bodies represented as a single polygon identified by a unique label.
- Compiled in Autodesk drawing file format
Center line features of streets and water bodies
- A set of vector data of every street and water body represented as a polyline identified by a unique label.
- Compiled in Autodesk drawing file format.
Topographic data or polyline features of contours8
- A set of three-dimensional polylines derived from suitable source maps, which have 20-meter contour intervals with supplementary contours at 10-meter intervals with the local mean sea level as the vertical datum.
- Every contour polyline represents a contiguous location with the same height, magnitude or concentration of values in the input grid
Indicative barangay boundaries with attributes and topology
- A set of barangay boundaries with demographic attributes based on the latest database of the National Statistics Office.
- These attributes include total population, household population, number of households, male and female population, number of disabled persons, overseas Filipino workers (OFWs) population

5 The accuracy of geographic data may vary from point to point. Details may be explained to the users upon request.
6 Topology refers to the geometric properties of linked geographical features.
7 A vector is a georeferenced representation of a feature as a point, line or polygon.
8 An imaginary line on the ground, consisting of points that are at the same elevation above or below a specified datum surface, usually local mean sea level.
