Can i be able to plot a points on maps with geodjango? i figured i can plot polygons on a map but struggling to plot points is it possible? if it is how do i do it or help with a link to information where i can find how to do that. i have been searching and cant find much infor about it.

If i can atleast plot a point like points on the map below, that would be great

- Well planned is half done and a half done has been sufficient before...

[Coulson Thabo Kgathi]

What i did so far is create a GeoDjango project, the define models as shown below
#models.py looks like thi

from django.db import models

# Create your models here.
# This is an auto-generated Django model module created by ogrinspect.
from django.contrib.gis.db import models

class Locations(models.Model):
    zid = models.IntegerField()
    name = models.CharField(max_length=20)
    elev = models.FloatField()
    icon = models.IntegerField()
    point = models.PointField()                             #this i tried to do it for the poin to be ploted
    geom = models.MultiLineStringField(srid=4326)
    objects = models.GeoManager()


# Auto-generated `LayerMapping` dictionary for Locations model
locations_mapping = {
    'zid' : 'ZID',
    'name' : 'NAME',
    'elev' : 'ELEV',
    'icon' : 'ICON',
    'point' : 'POINT'
    'geom' : 'MULTILINESTRING',
}


The rest of the files i followed the GeoDjango tutorial

but this does not seem to be working, First i tred bt using a .kml file convert it to a shapefile then import it to generate models bt does not work

How are you trying to plot your points?

Have you tried to manually insert at least one known point to be sure
that problem is not somewhere in your import process?

[Coulson Thabo Kgathi]

how i plot a point atleast manually is what i cant find how to do.

If atleast i could know how, which i think is done in the models.py then i would be good to go afterwards

What you really mean by "plot"?

If you mean that show it somehow somewhere on a map then there is really
nothing "built in" in Django for that. IIRC admin can show only
one (first?) geometry field defined.

So you need to have some kind of mapengine to actually produce map also
known as WMS (or WFS).

Mapserver, Mapnik or Geoserver being propably one of the most used ones.

After you have done that you can build HTML page that uses some means to
show map. OpenLayers is for that - it's javascript library to work with
(interactive) maps on a webpage.

Now you should have all pieces that allows you to put together stuff
that can show your points from a database.
