WFS 1.1.0: feature identifiers, gml:id and the FeatureId paramater in GetFeature

In section '7.1 Feature and Element Identifiers' the WFS 1.1.0 specification describes how to deal with feature identifiers.

Exhaustive list of Geometries covered in GML 3.1.1

Hi,

I am not able to find out an exhaustive list of geometries specified by GML3.1.1. By going through the GML specs, I am unclear on some of the items mentioned; whether to treat them as geometries or are they simply tags that are used to create other geometries?. I have listed out the geometries as per GML 3.1.1, pls guide me if any of them is not a geometry (but simply a GML property or tag) and also if I missed some of geometries:-

Handling multiple uomLabels and axisLabels in GML 3.1.1

Hi,

My application takes in geometry parameters from users in C Structures and creates equivalent WFS 1.1.0 transaction request. I am not clear as to how i need to mention multiple uomLabels and axisLabels in the POST xml that i generate for transaction request. Somewhere I read that multiple values are space delimited, but usage is not very clear to me. Pls help me with some example.

Thanks in advance.

gml:tin example

Dear All,

I am studying GML extensions documentations and
I have some difficulties in understanding how an actual TIN
structure is represented by GML.

I looked around to find
a real example but could not find such. Could you please
help me to find such example? I made up ax example (see below) which

represents the domain of a tin composed of four triangles (with no hole). Is that a correct representation? How about range set? Imagine each vertex has some associated data values 

AgroXML - Standardized, Platform-Independent Internet Data Exchange in Farm Management Information Systems

agroXML is a standardized language for data exchange in agriculture. It is based on the eXtensible Markup Language (XML) using XML Schema as its definition language. agroXML is used to submit data from farm management information systems to external partners, like e. g. product processing industries in the food supply chain or agricultural service providers. In addition, data about operating supplies like fertilizers or pesticides can be made available to the farmer by their respective suppliers. GML is used to encode all location elements in agroXML.

GML Java parsing

Hello. I'm starting a simple project (a GML minimal parser in Java, under LGPL), i have worked on several OGC catalogue projects and my focus was often on GML -> WKT conversion. I have found a lot of help on your site, and i hope to be able to (partly) give back.

WOML - Weather Objects Modelling Language

The primary goal of WOML is to define meteorological phenomena or other objects in a semantically meaningful way by using GML Feature model as the basis of the language. This is fundamentally different modelling decision compared to more data-oriented feature models, like Climate Science Modelling Language (CSML). Development for a GML Application Schema for Meteorological Objects, like weather fronts, rain areas and such, was started at Finnish Meteological Institute in autumn 2008.

O/R-Mapping of GML Application Schemas

Hi folks,

 

what's your opinion about storing complete GML Application Schemas to a relational database?
