Critical Errors in OGC's GML 3.1.0

Notes on XML Schema and why GML 3.1.0 is unimplementable

Review of FeatureType Models

Comparison of FeatureType models (from standards and open source)

Reference

Standards and other gis toolkits to mine for ideas ....

OGC

 

Open Geospatial Consortium
(industry standards body)

GeoAPI

api

OGC & ISO derrived Interfaces (that we use as often as possible)

Deegree

api

Another toolkit (GPL)

JUMP

api

JTS desktop app with its own feature model

GML2

xsd

Geographic Markup Language 2.1.2
(used by WFS 1.0)

GML3

xsd

Geographic Markup Language 3.
(used by WFS1.1)

Development

In Flight

These ideas are being actively worked on ... these usually have a svn branch and target version!

2.2

August

 

M0

HSQL DataStore

Done, Merged, released

M1

Main Split

Done, Merged, not released

2.2

September

 

M2

FeatureVisitor

Use of visitor rather then for loop allows for stats

2.2

October

 

M3

Random Data Access

allow random access to feature content (based on indexes)

M4

Community Schema Support and Complex Types

Support for interoperable schemas, with complex properties

 

Project page

 

Feature Model Design

Support for XPath query model and Compex types

January

 

M5

Grid Coverage Update

Move from OpenGIS to ISO 19111

M6

Grid Coverage Data Access

Exciting development happening in conjunction with GeoAPI

2.2

No Deadline

 

 

Rendering Optimization

more data rendered faster

 

Map, Layer, Data and Rendering Architecture

Build a unified map, map layer, data access and (general) rendering concept based on existing concepts in GeoTools, GeoAPI and uDig.
Work has started on the geowidgets project

 

Public Domain GeoTIFF plugin

A GridCoverageReader plugin for GeoTIFF files

Sketches

Developer scratch pad for new and wonderful ideas ... no branch, or target version!

Idea

CatalogAPI

Bring GetServer Data, GeoTools registry and UDIG Catalog into a shared codebase

Proposal

Coverage Support Plans

Plans for coverage support, concocted by those who need it.

Proposal

Multidimensional Georegistered Grid

API for selecting a 2D slice from nD data.

Proposal

J2SE ImageIO in 2D

A plan for isolating grid plugins from OGC/GeoAPI/Geotools instability

Idea

GUI Architecture

 

Idea

Dynamic Styling

 

idea

Operations API
