[Geoserver-users] Custom DataStores

Simone,

Thanks for your advice.

I am trying to write a plugin that takes data from a set of SOAP Web
Services and channels the data through the WMS/WCS interfaces and allows
Google Earth to visualize my data.

Therefore, I need a place for GeoServer to hit my Web Service, obtain
the data and do whatever magic it does to go ahead and prepare the data
to be visualized on Google Earth via the WMS/WCS interfaces.

Based on the input I received from Andrea, Justin and several others,
this method seems like the best way to go about this.

Is this all correct?

Ciao Ronak,
as you have noticed the documentation for creating new raster formats
is, let's say, rather sparse and pretty bad.
However, as Andrea Aime suggested the best thing do it so get one of
the other raster plugins, like gtopo30 or arcgrid + the geoapi javadoc
to look for examples.

Anyway, to give some help:

- accepts can be used by your format to check if you can accept or not
the provided source which can be pretty anything
- getReader and getWriter shoudl reaturn either a reader or a writer
for the provided source if it si recognized/supported otherwise they
can return null.
- the lookup for coveerage and datastore pugins is done via SPI based
on ServiceRegistry spring is not directly involved in this.

Just out of curiosity, a bit more info about what you are trying to
achieve in terms of formats could give us more ways to help you out.

Ciao,
Simone.

Andrea,

Thanks for helping out with answering my questions.

I see method signatures such as:

Boolean accepts(Object input)
getReader(Object source)
getWriter(Object destination)

1. What are the sources, inputs, and destination? Where does it come
from?
2. I retrieve this information from a web service call to an external
service so I would put my logic for that here. Are there any patterns

I

should be following for that?
3. How does my implementation of these things get plugged into
Geoserver? What does the spring configuration have to look like?

Thanks,

Ronak Patel

Got it. Thanks.

It still seems to be using deprecated classes. Is there another class

I

should be using instead? Or is the deprecation okay?

Mumble, I don't really know as I don't play much with Coverages,
but I can tell you in Geotools it's hard to write any code
without stumbling into classes that someone deprecated without
providing a complete replacement with them (crazy, I know...)

Cheers
Andrea
