Project from Lambert Azimuthal Equal Area Projection Definition to WGS84

GuillermoMarques — Tue, 22 Apr 2014 11:19:25 GMT

Hi
I´m trying to project a raster from Sphere_ARC_INFO Lambert Azimuthal Equal Area Projection Definition to UTM WGS84
This raster has been downloaded from http://phenology.cr.usgs.gov/get_data_250e.php and I wanted project

Can somebody help me please, because when I load into I show it with an offset. Thank you so much.

Regards,
Guillermo

Hello Guillermo,

The UTM Datum WGS84 has Zones as in UTM Datum NAD83. Since this image encompasses multiple zones, I do not know how it works out or what zone you assign it to (unless there is a universal Zone). However you can re-project this to Geographic WGS84 (units in lat/long) or WebMercator (units in meters). Both worked fine.

Hello Samuel
The problem is that when layer is transformed the result is shifted, even when I project to Lat/long, what I need is to know how to do this in ArcGIS with no shifting

Hello,

Try unprojecting the data to its GCS (ArcInfo Sphere), then use the Define Projection tool to change the coordinate system to WGS 1984. At that point, try adding it, with your other data, to ArcMap. If it lines up, use the Project to convert to the final coordinate system that you want to use.
