title: Reading latitude/longitude coordinates from csv into ArcGIS
body: <p>I am new to ArcGIS and I understnad this could seem a silly problem, but I have been trying for hours and can't seem to solve it.
  I have data of cetacean (whale/dolphin) sightings with their associated GPS coordinates in decimal degrees (format like 41,345867). I have read them into ArcGIS desktop, but when I add a basemap I see that ArcGIS is reading my coordinates in meters instead of decimal degrees, which is why the points show all very close to each other and to the equator and greenwich meridian.
  ArcGIS itself automatically chose the correct colums of my database as lat and long, but reads the number in meters.
  I have tried changing the coordinate system used in the environment settings, but I can't figure out how to tell the program the numbers are decimal degrees.</p>
  <p>Any help highly appreciated!</p>
  <p>Thanks</p>
