Common mistakes with NAD83(HARN) / Maine CS2000 West
- Easting and northing swapped. In NAD83(HARN) / Maine CS2000 West the middle of the grid is near easting 302,372.55 and northing 221,287.93. If your easting column holds numbers like 221,287.93, the columns are the wrong way round and every point lands far away: swap them before converting.
- Feet entered as metres. NAD83(HARN) / Maine CS2000 West 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. NAD83(HARN) / Maine CS2000 West 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. NAD83(HARN) / Maine CS2000 West is meant for United States (USA) - Maine west of approximately 69°40'W. The area is bounded by the following: Beginning at the point determined by the intersection of the Maine State line and the County Line between Aroostook and Somerset Counties, thence following the Somerset County line Easterly to the Northwest corner of the Somerset and Piscataquis county line, thence Southerly along this county line to the northeast corner of the Athens town line, thence westerly along the town line between Brighton Plantation and Athens to the westerly corner of Athens, and continuing southerly to the southwest corner of the town of Athens where it meets the Cornville town line, thence westerly along the Cornville - Solon town line to the intersection of the Cornville - Madison town line, thence southerly and westerly following the Madison town line to the intersection of the Norridgewock - Skowhegan town line, thence southerly along the Skowhegan town line to the Fairfield town line, thence easterly along the Fairfield town line to the Clinton town line (being determined by the Kennebec River), thence southerly along the Kennebec River to the Augusta city line, thence easterly along the city line to the Windsor town line, thence southerly along the Augusta - Windsor town line to the northwest corner of the Lincoln County line, thence southerly along the westerly Lincoln county line to the boundary of the State of Maine as determined by Maritime law, thence following the State boundary on the westerly side of the state to the point of beginning. 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.
