Re: saving latitude and longitude values in django

[Derek]

Also: just came across this mapping example, using Leaflet, and a 
standards-based approach (POST via WFS) to write point data from the map to 
a database:

http://blog.georepublic.info/2012/leaflet-example-with-wfs-t/
https://github.com/Georepublic/leaflet-wfs/blob/master/index.html#L201  
(POST code)

Re: saving latitude and longitude values in django

[Derek]

Your question seems to be more about using javascript with Django; have a 
look at this Q:
http://stackoverflow.com/questions/5735107/basic-django-and-javascript-question
There is also a lonk to a downloadable sample app.

The "getting the values from the map via javascript" is a different kind of 
problem altogether; you'd need to ask about that on a javascript forum.

Re: saving latitude and longitude values in django

[Vernon D. Cole]

Saving the values is the easy part.  The format you use depends on what you 
want to do with them.  If you are only displaying them to users, CharField 
might be okay.  If you are going to do any processing, you should probably 
convert them.  My storage is done like this:

gpsLatitude = models.FloatField("Latitude", blank=True, null=True,
> help_text="degrees, floating point, South is negative")
> gpsLongitude = models.FloatField("Longtitude", blank=True, null=True,
> help_text="degrees, floating point, West is negative")
>

Getting the values may be a problem. I do not understand what you mean by 
"displayed in map using marker".  Is what you have is a graphical image 
with a marker icon somewhere on it?  Or are you using a Google api which  
can be asked to give you more information?

Re: saving latitude and longitude values in django

[Doug Snyder]

I think you'd at least want to use either a DecimalField or FloatField for
the lat & long numbers.
There's a nice GIS package in django called GeoDjango, it has lots of built
in functionality for all kinds of geographical things.
This may be over kill for your application but I thought I'd let you know
it exists.
One thing it allows you to do is query the DB based on location, i.e.
distance between points with lat & long.
You could compute this using a standard norm calculation but its slow
compared to using a native DB query.
