comment geodjango difficulties with srid
Could you show how exactly you are trying to add a point? Is it through the admin, or in a view/script? If your data has srid 4326, then adding a point might throw an error because it has the wrong sird...

What do you mean with "adding"? Adding a new point?

comment Unable to create Polygon using Geodjango admin interface
From your error message my guess is that you are pasting the geometry wrongly in the admin interface. For instance, in the admin, you should add the geometry without the quotes. What exactly are you putting into the form on the admin site?

comment How to dispay my PostgGIS geometry on the GeoDjango map widget?
This is a random guess, but have you tried the OpenLayersWidget instead of the OSMWidget. From the docs it seems that the one you are using is just for adding a map with a base layer.

comment How to compare a classified raster dataset to another polygon dataset?
Is your dataset raster-based? If I understand right, you have polygons outlying soil types and a few raster images that you will use for classification. Then you want to compare the unsupervised results with the polygon values. Is that right?

comment Is there an open standard for raster information?
Thanks Jonathan the GML standard is along the lines of standards I was looking for. @user30184 - I have not thought of the image formats as raster standards, but I guess they can be considered as standards for some of the formats that allow GIS metadata. However, for my use-case those formats are too complex. Ultimatively I was looking for a simpler and truely GIS focused standard that is not as verbose as GML.

comment How to merge an excel file with a shapefile in r
is nrow(data) == nrow(data1) == nrow(data3)? There is a chance that you are loosing rows in the merge step if the ZIP3 lists are not the same. Then you could try merge(data2,data,by="ZIP3", all=TRUE)

comment What are the PostGIS Raster Constraints used for?
Thanks for the explanation. This makes sense to me, but does that mean that the raster constraints are not a requirement, but rather a way of self-imposing constraints on a table? I see the usefulness if one tries to have only one "type" of raster in a table (with specific srid etc), but if I understand your answer correctly, these constraints are voluntary, so I can leave them away if I keep track of srids etc in another way? i.e. no part of PostGIS raster relies on them...?
