Common mistakes with Luzon 1911 / Philippines zone I
- Easting and northing swapped. In Luzon 1911 / Philippines zone I the middle of the grid is near easting 548,837.12 and northing 943,861.58. If your easting column holds numbers like 943,861.58, the columns are the wrong way round and every point lands far away: swap them before converting.
- Feet entered as metres. Luzon 1911 / Philippines zone I is in metres. Coordinates copied from a drawing in feet must be converted first, or every point moves outwards from the grid's origin.
- Forgetting the datum. Luzon 1911 / Philippines zone I is not on WGS 84: published 3-parameter shift (typically a few metres). Picking a WGS 84 grid with the same projection instead leaves the points off by that amount.
- Points outside the grid's area. Luzon 1911 / Philippines zone I is meant for Philippines - onshore west of 118°E. Points well outside that area convert with growing error; the converter flags them so you can choose the right grid.
- A local site grid. If every point is off by the same distance and direction, the drawing may be on a local site grid. Calibrate on three or more known control points instead.
