Common mistakes with WGS 84 / BLM 14N (ftUS)
- Easting and northing swapped. In WGS 84 / BLM 14N (ftUS) the middle of the grid is near easting 2,438,264.55 and northing 9,878,490.13. If your easting column holds numbers like 9,878,490.13, the columns are the wrong way round and every point lands far away: swap them before converting.
- Metres entered as feet. WGS 84 / BLM 14N (ftUS) is in US survey feet. Enter the values as they are; converting them to metres first puts every point in the wrong place.
- Looking for a datum shift that isn't there. WGS 84 / BLM 14N (ftUS) is defined on WGS 84, the datum Google Earth uses, so no shift is applied. If points are off by tens or hundreds of metres, the data is probably on another grid.
- Points outside the grid's area. WGS 84 / BLM 14N (ftUS) is meant for United States (USA) - Gulf of Mexico outer continental shelf (GoM OCS) west of approximately 96°W - protraction areas Corpus Christi; Port Isabel. 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.
