How can I adjust the coordinate system so that the dataset shows up as a whole?
I've got a grid in lat/long (wgs84) that spans from Australia to the mid Pacific...when I load it in ArcMap (or look at it in ArcCatalog for that matter) it's split in half. The Eastern half (East of 180°) shows up on the left side of the screen. How can I adjust the coordinate system so that the dataset shows up as a whole? I've tried to play around with the Prime Meridian setting, but no change.
Mapping Center Answer:
Change the central meridian to something like -160 (that will get you started and you’ll need to adjust that number to get the map to look exactly as you want it to). To change the central meridian the data frame’s coordinate system must first be set to a projected coordinate system (as opposed to only a geographic coordinate system):
1. Go to data frame properties, then on the Coordinate system tab, click the Modify button.
2. In the parameters list, change the value of the “central_meridian” – just click on the current value and you’ll be able to edit it.
3. Click OK and OK.
