Recovering Latitude and Longitude from Albers to Compute Distance I defer to geodesists to answer that but for my purposes I have always been happy to use Albers or Lamberts. |

Distance of many polygons to a segmented line "TARGET_FID just creates an identifier for every polygon" makes me think you have reversed the two inputs but in any event it sounds like you are getting a better understanding of how to use and the power of Spatial Join now. |

Compiling a list of units that border each other Only one shapefile is input - could be counties for whole of US or if your focus is counties of Georgia, North Carolina and no other states then select these out into a new starting shapefile first. |

Use python to add layers to TOC I was looking for @geogeek's remarks but they appear to be absent. In any event, as his corrected code shows, you need to create the MapDocument and DataFrame objects outside of the loop that runs through your layers. Otherwise you are starting with the original map each time. |

Feature Class - Adding domain to have dropdown box in Attribute Table You will also need to click on the field in the feature class properties in order to see the properties of that field and choose whether to use a domain. If no domains are seen, check that data type of domain and field you wish to use it with match. |

How to rotate labels using ArcPy? As a workaround you could try rotating the labels of your layer and save that as a layer file, then when you need rotated labels for that layer use AddLayer to add the layer file. |
