[mapserver-dev] MS RFC 61: Enhance MapServer Feature Style Support

[Lime, Steve D (DNR)]

I'd hope you'd be able to deduce the format from the style string, that is, OGR vs. SLD.  I guess I'd leave that out until necessary.

Just to keep the things consistent in the future, how about adding a new keyword to the LAYER in order to select the desired style format, like:

LAYER
    STYLEITEM "OGR_STYLE"
    STYLEFORMAT OGR
    ...
END

Agreed... I'll defer to the OGRites out there on the implementation details but It seems straight forward enough.

Steve,

I didn't want to promote the OGR style as opposed to SLD or other style representations, on the contrary I would be happy have them implemented all. But at the moment - for practical reasons - implementing the OGR styles would be more straightforward. From the user's perspective having a 'feature style ready' data source (like mapinfo tab) in hand, can easily be converted to any other data sources supported by OGR using a single commandline tool. It would then be reasonable to establish support for rendering those feature styles in mapserver by using the "native" drivers as well, not only with OGR like now.
For this reason I'd encourage to enhance such default style handling (established with this addition) to support more kind of the style representations if someone will have any motivation to implement a parser to those styles. Till that time, having a single implementation in place is much better than denying such support at all.


Best regards,


Tamas

Folks are kinda quiet... Recovering from the conference no doubt. This seems a reasonable idea. Only question I have is promoting the use of OGR styling as opposed to SLD.

Hi Devs,

I would require an implementation to extend the current STYLEITEM option to be used with further drivers in addition to OGR driver. I recall we have already been discussed this topic with the conclusion that this kind of implementation would require quite a big effort, but I expect the initial approach (based on the OGR style) could be implemented fairly easily. For this reason I've created MS RFC 61 describing the concept to be done, though the proposed changes haven't yet been implemented by me. I'd anyway be in favour of adding such solution (or a reasonable variant) to be available in the next release version (ie. MS 6.0)

The RFC can be found at:

Best regards,

Tamas
