Comparative Reference Matrix of All 10 mapaPH Utilities
Every utility in the mapaPH directory is built around an authoritative Philippine statutory standard, geodetic datum, or public regulatory tariff schedule. The table below outlines the governing agency, underlying dataset scope, and primary output of each tool:

| Metro Manila Rail Guide | DOTr, LRTA & LRMC | 51 Stations Across LRT-1, LRT-2, MRT-3 | Station-to-station Single Journey vs beep card fare tables, travel time, and footbridge transfer guides. |
| Expressway Toll Calculator | Toll Regulatory Board (PD 1112, JAO 2024-001) | 7 Major Tollways (Class 1, 2, 3) | Entry-to-exit TRB toll fee computation, schematic plaza strip, Autosweep vs Easytrip RFID assignment. |
| EDSA Carousel Busway | LTFRB Route E & MMDA | 21 Median BRT Stations (28.1 km) | Stop-by-stop Monumento to PITX fare schedule, schematic ribbon, and rail concourse links. |
| Kilometer Post & KM 0 Locator | DPWH DGCS Vol. 4 & NHCP | 5 Regional KM 0 Origins & 7 Trunk Roads | Concrete DPWH marker anatomy decoder, corridor chain inspector, and Bataan Death March mileposts. |
| Lens Web Application | PSA, COMELEC & COA Open Data | 42,000+ Barangays & 1,642 LGUs | Interactive choropleth visualizer, side-by-side LGU comparison, and RFC 7946 GeoJSON boundary export. |
Chaining Utilities: Practical Workflows for Researchers and Commuters
While each tool operates as a standalone calculator, they are designed to interoperate using shared geographic identifiers and coordinate standards:
Building a Standardized LGU Spatial Dataset
- Normalize Administrative Keys: Query target municipalities in the PSGC Lookup to retrieve their canonical 10-digit PSA code and 2024 census population baseline, avoiding spelling conflicts (such as Parañaque vs Paranaque).
- Cross-Reference Postal Logistics: Click through to the PHLPost ZIP Directory to map municipal boundaries to their 4-digit postal routing zones for household survey or logistics sampling.
- Reproject Field Survey Tie Points: Use the Coordinate Converter to transform legacy DENR cadastral coordinates (PRS92 / Clarke 1866) into WGS84 decimal degrees.
- Export Vector Polygons: Launch Lens or consult the GeoJSON Developer Guide to join your PSGC-keyed table with RFC 7946 boundary polygons.
Auditing Multimodal Metro Manila Transit Costs
- Measure First-Mile Catchment: Pin your residential origin or office destination on the Walkability & 15-Minute Radius Map to identify which rail stations or busway terminals fall within a 400m to 800m shaded walk.
- Compare Trunkline Rail vs. BRT: Check station-to-station stored-value beep fares and footbridge transfer times on the Metro Manila Rail Transit Guide alongside 24/7 median busway rates on the EDSA Carousel Calculator.
- Verify Last-Mile Feeder Tariffs: Enter the remaining distance into the Commute Fare Estimator to compute exact LTFRB legal fares for Traditional or Modern Jeepneys, including mandatory 20% student (RA 11314), senior (RA 9994), and PWD (RA 10754) discounts.
- Evaluate Private Vehicle Toll Alternatives: For inter-provincial trips across Luzon or Cebu, compare public transit costs against Class 1 expressway tariffs and RFID wallet requirements in the Expressway Toll Calculator.
Browser-Native Architecture & Open-Data Integrity
Unlike conventional web directories that rely on slow database round-trips or rate-limited third-party APIs, every calculator in the mapaPH suite compiles its reference datasets directly into static client-side bundles during the Astro build process. This architecture delivers three concrete advantages for Filipino users:
Zero-Latency Mobile Search
Once a tool page loads on a mobile connection, filtering across 1,742 PSGC divisions or 2,139 PHLPost ZIP codes executes in under 5 milliseconds inside browser memory, remaining responsive even on intermittent provincial cellular data.
Verifiable Statutory Formulas
Every mathematical formula, whether a piecewise LTFRB per-kilometer tariff or a 7-parameter Helmert datum transformation, is written in readable, unminified open-source code accompanied by its exact Republic Act or Department Order citation.
Privacy by Design
Because coordinate conversions, radius pins, and route selections are computed locally on your device, your location queries and travel itineraries are never logged to a backend server. Read our Technical Documentation to learn more.
