How can I reclassify a raster to floating point values? allows for a join if scaled properly and appropriate field data exists for the join. I guess I assumed this would have been obvious beyond a 1st year GIS course...but point taken |

python script to calculate and return values based on several conditions conditional statements in arcmap are carried with the Con statement. Read the appropriate help files for your version. Con is like an "if" statement in other programming languages. If you want to implement this in pure python the the if-elif-else syntax will work. Details are needed. |

create grid cells of fixed dimension around a point acting as a centroid Whuber, Perhaps I was thinking of what happens when using a UTM projection, then trying to perform a select by location (within) which produces erroneous results if the selection grids are not densified prior to projection. |

create grid cells of fixed dimension around a point acting as a centroid Yes PolyGeo, originally this designed to run in 10.0 ArcView and it should run at all license levels in 10.0 and 10.1. It also allows you to produce a point file showing the locations of the densified points if they are needed for other analyses. |

Is it possible to create map packages for ArcMap version 10 using 10.1? Mapperz had already posted what your proposed. Read his post and you will see the ALL option was already indicated. Welcome to the site in any event. |

Field added to raster data is not visible in attribute table Was the table open when you did this? Did you try closing then reopening the table? See Polygeo's explanation as well. |

They will be flat in the East West direction rather than having the appropriate curvature which would be expected when following a parallel. See resources.arcgis.com/gallery/file/geoprocessing/… and experiment with various densifications (eg start with a 0.1 or 0.2 degree densification) |

Best way to get the overlapping segment of two lines Just a wild guess, is that there may be some option to specify the output geometry type. In many packages the default output is a line, so check O-S to see if you can modify the output. I know it can be done in other packages, but for specific input geometries. |

Tabulate Area crashes Python and ArcGIS Then could you provide the results of the print statements Brian so the line of failure can be examined? |

Do I need to use an output backlink raster in Cost Distance tool? Check out costpath analysis in the help files. The requirements to get the actual path, and hence, its length etcetera are explained there. |

Tabulate Area crashes Python and ArcGIS I would put some arcpy.GetMessage... lines in your code to provide some feedback so you at least know where it is failing of no errors are being reported. |
