SDI workflow demo

In my previous post I was talking about a CSWclient prototype. During the Autodesk EMEA GeoSpatial TechCamp2008 in Disneyland Paris, I’ve presented an SDI workflow demo on mainstage.

A city is planning a new housing area and has to extend the existing water, gas and electricity networks.
On the existing basemap they have planned the new houses and streets, and from the utility company they would like to add the existing infrastructure to connect the new utility design.
With the CSWclient they ask the SDI from the utility company about available maps in the area ‘Kouwenhovenselaan’.
The response from the SDI – a list with references to available maps – is used to connect the maps to the AutoCAD Map work-session.

The trenches for the new utilities go to the contractor, who returns an as-built drawing with the exact location after the construction has finished.
On this kind of CAD-drawings the contractor is using texts to mark the used materials and diameters.
It is important to migrate not only the location information, but also materials and diameters into the utility maintenance database.

With a special function in AcClassify it is possible to find texts on a certain layer within a buffer around the lines.
These text values are written as diameter attributes into the database.

How SDI-ready is AutoCAD Map

Refering to the GSDI 11 World Conference I’ve had several questions about the SDI-readiness of AutoCAD Map.

An important part in the concept of SDI (= Spatial Data Infrastructure ) is the Catalog Service, the source where you look for available geospatial data for your project. Comparable with the catalog in the library – in which corridor, on which book-shelf is the book about that particular topic.

One of the first activities when starting an SDI is to put metadata information into the Catalog Service. Metadata (= information about the data ) tells something about availability, quality, data-format, if it’s free of charge, on which server it resides, who is the administrator etc.etc. A Catalog Service is not a data service, but it refers to the source of the data.

AutoCAD Map has functionality to maintain metadata conform ISO19139. There is however no fuctionality ( yet ) to publish this into the Catalog Service, query the service and collect the data ( Publish – Find – Bind ).

Some time ago I’ve developped a prototype ( see screenshot below ) With this CSWclient application in AutoCAD Map, I could upload ISO metadata XML-files to a deegree opensource Catalog Service. Next I could query based on projectinfo and parse the response from the Catalog Service – an XML-message – to connect to the files.
