+# pyned2lla - NED (North East Down) to LLA (Latitude Longitude Altitude) conversion for Python
+
+## Example use
+
+```python
+import pyned2lla
+import math
+
+D2R = math.pi/180.0
+R2D = 180.0/math.pi
+
+wgs84 = pyned2lla.wgs84()

+
+(lat, lon, alt) = pyned2lla.ned2lla(lat0*D2R, lon0*D2R, alt0, north, east, down, wgs84)
+print((lat*R2D, lon*R2D, alt)) # Institute of Biology I, Faculty of Biology, University of Freiburg
+```
+
+The above should print approximately `(48.00771378931424, 7.8561542926911985, 261.21592491399497)`.
