I want to determine the coordinates of my current data frame. To do so I wrote this script:
def DataFrame (): mxd = arcpy.mapping.MapDocument("CURRENT") df = arcpy.mapping.ListDataFrames(mxd,"Layers") return mxd,df def Center (df): extent = df.extent xmin = extent.XMin xmax = extent.XMax ymin = extent.YMin ymax = extent.YMax x = xmax - ((xmax - xmin)/2) y = ymax - ((ymax - ymin)/2) return x,y
As long as I am working with a geographic coordinate system, the results will be exactly the longitude and latitude. But as soon as I have a projected coordinate system it will return map units (i.e. meters). How can I avoid that problem? I always need to get lon/lat independend on the maps projection.
