geodjango

I have an application that has been storing longitude and latitude now i want to integrate it with geodjango the application looks like this. class Location(models.Model): #other fields here lat = models.CharField(blank=True, max_length=100) lng = models.CharField(blank=True, max_length=100) now I will like to filter locations based on a distance say filter all location 1km away from location with pk = 1 using django.contrib.gis.measure import D and GEOSGeometry or should i refactor the model to have point rather than longitude and latitude so i can do something like this : Location.objects

I'm trying to add coordinate information to my database, adding django.contrib.gis support to my app. I'm writing a south data migration that takes the addresses from the database, and asks Google for the coordinates (so far I think my best bet is to use geopy for this). Next I need to convert the returned coordinates from WGS84:4326 , Google's coordinate system, to WGS84:22186 , my coordinate system. I'm lost among the GeoDjango docs trying to find a way to do this. This far, I gather I need to do this: gcoord = SpatialReference("4326") mycoord = SpatialReference("22186") trans =

I am having a real trouble in setting up spatial database and syncing it with GeoDjango. I was able to setup the spatial database as per the geodjango documentation and create a django app but when i run python manage.py sqlall world I am getting this, Traceback (most recent call last): File "manage.py", line 10, in <module> execute_from_command_line(sys.argv) File "/home/smaranh/django-env/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 443, in execute_from_command_line utility.execute() File "/home/smaranh/django-env/local/lib/python2.7/site-packages/django/core

I am trying to use Geodjango on mac os, i use postgresql and I installed GEOS but i got this error : dlopen(/usr/local/lib/libgeos_c.dylib, 6): no suitable image found. Did find: /usr/local/lib/libgeos_c.dylib: mach-o, but wrong architecture Any idea? Thank you Sebastien Ok, I have my answer. My MAMP uses 32-bit Python and I compiled my library for 64-bit Python. So I recompiled it for 32-bit Python. To do this, I used these commands in my library folder: export CFLAGS=-m32 export CXXFLAGS=-m32 ./configure make make install 来源： https://stackoverflow.com/questions/6564114/geo-django-mac-os-x

Looking to store a circle in a geodjango field so I can use the geodjango query __contains to find out if a point is in the circle (similar to what can be done with a PolygonField). Currently have it stored as a Decimal radius and GeoDjango Point Field, but need a way to query a list of locations in the DB such that these varying circles (point field and radii) contain my search point (long/lat). Hope it makes sense. Mike T Technically speaking, PostGIS supports CurvePolygon and CircularString geometry types, which can be used to store curved geometries. For example, a 2-unit radius around x

I have tried to find some documentation on this on the app engine and cloud sql sites, but can't find anything referring to it either way. I know that you can perform GIS queries on their custom sql option, and I know mysql supports GIS out of the box, but I also know it requires some C libraries which there is limited support for. More particularly I am interested to know if geo-django using mysql supports gis using an app engine/cloud sql combination. (Or maybe if their custom offering supports geodjango?) GeoDjango with Cloud SQL is not supported. GeoDjango depends on several libraries that
