I like data and cities as laboratories of the interaction between behavior and technology.

Joining Tables, points and polygons ArcGIS Are you using a near full personal geodatabase (~2GB)? Do you have adequate disk space? |

Identify points near roadside in QGIS Sounds like you need to decide how far from the road you will consider "along" it. Then run a buffer on your road feature and select points using that. Both functions are found under the vector menu, under Geoprocessing Tools and Research Tools, respectively. |

repeating records in attribute table You say "I can't seem to get the attribute table to accurately reflect the records"--does that mean you have a non-spatial version of the data file to compare against? Does that have an object ID carried over to the shapefile? |

How to convert jpg file to shapefile? Is this a one-off, or do you need to digitize many maps? There are really no short cuts here; these things tend to require lots of hand holding and judgment, especially if topology matters. |

Create multiple shapefiles from one table Have you tried this one? resources.arcgis.com/gallery/file/geoprocessing/… |

Create multiple shapefiles from one table Interesting. 4000 records doesn't sound like a lot to me. Depending on how many times you need to do this (one off? frequently?), and how many unique combinations you will have of col1, col2, col3, you may want to split the table before importing/displaying in arcmap. |

Create multiple shapefiles from one table Do you use a database software? That appears to be the easiest option. Then concatenate col1, col2, col3 into a new field and select based on unique values of the resulting variable. Or you could perform the concatenation in ArcMap's field calculator and presumably feed that to the Fox Tools (haven't used it, but it seems your problem was having your criteria in three columns.) |

How to crop Shapefiles in QGIS? Are you saying you are clipping a line (road) layer with a polygon layer? And are you after just ONE polygon area for your output, or multiple? |

Can I Combine Areas in Quantum GIS? Thanks for the clarification. I was not entirely sure whether that was "batteries included". |

how does a personal-gdb work from a MS Access perspective? I have been recklessly working with attribute data of key GIS files using MS Access, finding it much easier to work with for basic updating and reporting than ArcMap. Just don't mess with the GDB-prefixed tables which are automatically maintained by ArcMap. |
