Common mistakes with Lake / Maracaibo Grid M1
- Easting and northing swapped. In Lake / Maracaibo Grid M1 the middle of the grid is near easting -29,490.29 and northing -15,802.07. If your easting column holds numbers like -15,802.07, the columns are the wrong way round and every point lands far away: swap them before converting.
- Feet entered as metres. Lake / Maracaibo Grid M1 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. Lake / Maracaibo Grid M1 is not on WGS 84: treated as WGS 84, no shift (the datums agree to about a metre or better). Picking a WGS 84 grid with the same projection instead leaves the points off by that amount.
- Points outside the grid's area. Lake / Maracaibo Grid M1 is meant for Venezuela - Maracaibo area, onshore and offshore in lake. 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.
