Common mistakes with Lake / Maracaibo La Rosa Grid
- Which column is which. In Lake / Maracaibo La Rosa Grid eastings and northings near the middle of the grid are of similar size (about 12,604.15 and -13,357.01), so a swap won't be obvious from the numbers. Check that the first point lands where you expect it before converting the rest.
- Feet entered as metres. Lake / Maracaibo La Rosa Grid 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 La Rosa Grid 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 La Rosa Grid is meant for Venezuela - Maracaibo area offshore blocks I, II and III. 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.
