Lot Plotter
Turn the technical description on a TCT or OCT into lot corners you can open in Google Maps. Check the closure and the area against the title, then see the lot on satellite imagery.
Everything runs in your browser. Your title and its text are not uploaded to Han Ja or anyone else.
The plotted lot is an estimate, not a survey. Errors in the title text or the reading of it, monument coordinates, datum conversion and map imagery can each shift or distort the outline by several metres or more. Confirm boundaries with a licensed geodetic engineer before buying, building or fencing.
1 Technical description Sample title
Or drop the file here. Text PDFs are read exactly. Photos and scanned PDFs are read by text recognition on your device, so check every number afterwards.
2 Anchor on the ground
The title's monument is matched to the list automatically; pick another to override.
Outside Bataan, find the monument in Google Maps, right-click it and click the coordinates to copy them, then paste here.
Monument coordinates come from the DENR Land Management Services or the approved survey plan.
Fine alignment
Use these when the plotted lot sits slightly off the fences on satellite imagery, as older surveys on true or magnetic bearings often do.
3 Put it on Google Maps
- Download the .csv file.
- Open mymaps.google.com, create a map, and choose Import under the first layer.
- Pick the file. The lot outline and the tie monument appear; switch the base map to Satellite to check it against fences.
Google Earth: open the KML file under Projects, then Import KML file.

Bearings are plotted as grid bearings on the Philippine Transverse Mercator zone of the anchor point; datum shifts use the standard EPSG parameters for PRS92 and Luzon 1911. Monument list: Geoportal Philippines' Lot Plotter tie points for Bataan and the Bureau of Lands list of reference-point positions; a pick is only as good as the list, and official coordinates come from DENR / LMB. This is a planning and verification aid, not a relocation survey. Boundary disputes and titling need a licensed geodetic engineer.
