I do web development, mostly PHP using the Zend Framework but I'm starting to get involved in a little Python & Django.
Hit me up, I'm pretty knowledgable about a wide variety of development trivia.

Usage of GeoDjango I thing you need an = sign: qs = Events.objects.filter(point__distance_lte=(pnt, D(km=5))) |

geodjango slowness and debugging i went ahead and marked this as the answer, the project got pulled and i'm no longer working on it. thanks for the great discussion. |

geodjango slowness and debugging im dealing with US census data mostly boundaries for states (some like VA, some like HI). islands seem to need to be handled separately because the distances between those points are more significant. I almost fell like simplification shouldn't be based on a constant. Instead siimplification should reduce points based on some factor of standard deviation of distances between points for each specific polygon. |

geodjango slowness and debugging in that case I'm back to my original question, how do you determine programatically the correct tolerance? |

geodjango slowness and debugging that is interesting, I think the simplify function in geodjango may be buggy then. On smaller polygons I noticed that If i specified a tolerance too high that the polygon would break (not validate as a geos polygon) I figured that had to do with oversimplification and that I should adjust the simplification level based on the number of nodes (which worked to a degree, but seemed error prone) |

geodjango slowness and debugging I figured reducing the number of vertices would be key, however, choosing the simplification factor for each polygon seems not as straight forward. any idea on a good algorithm for that? my get_tolerance(num_points) function sometimes breaks if it tries to simplify a poly too much. Thanks for responding |

geodjango slowness and debugging Thanks for migrating this question over. I may leave it open for a while and see if anyone has a better solution than what I came up with. Thanks for taking interest. |
