[Geoserver-users] Best raster format?

GeoServer GeoServer User
1

The NWS Java NEXRAD data exporter is capable of generating a NEXRAD raster image in the following formats:

    * ESRI ASCII Grid
    * ESRI Binary Grid (.hdr file with ASCII header info and .flt file with binary float data)
    * GrADS Binary
    * NetCDF
    * GeoTIFF
    * VTK

Any thoughts on which format might be the best?
Thanks, David Robison

Very different beasts the ones you list. Anyways, the one we read with best performance now is GeoTiff, especially if it's innerly tiled.

Side note: don't know if this helps, but you could also use the live WMS server from Iowa State.

Has any thought been given to developing an OGC Open Location Service (OpenLS) service for geoserver? Does anyone know of an open source implementation of the OpenLS service?
Thanks, David Robison

Hi David,

I wrote a (Java5+) API for the complete OLS 1.1 spec when I was working for LISAsoft/TerraPages.

http://terrapages.net/opengis-api/

It works excellent, is very simple to use, its fast and it is the complete OLS spec! I can no longer speak on behalf of the company but if nothing has changed, then it is not ‘officially’ opensourced because no one has adopted it for one reason…

This is the complete OLS spec nothing less and nothing MORE. Specifically if you want to add your own custom content (xml element or attibute), this " Extensibile" functionality is not provided. There is merit to such a requirement but it is also additional complexity that is holding up what would otherwise be an easy (and now working) service implementation.

And FYI: I also co-wrote the service implementations, and clients that use these services. It’s amazing how much value you can get out of this specification when its so easy to use!
https://terrapages.net/opengis-xls/

Anyway, the LISAsoft boys are working pretty closely with Geoserver these days and they should notice this thread.

–Over and out

Well I can speak for myself when I say that something like this
integrated with GeoServer would be super cool. Whats the status of it
being open sourced?
