Support layer style definitions based on SLD-Files (Styled Layer Descriptor | OGC ) - Load AND Save. It would improve interop. with other tools and software and data from organisations like European Environment Agency.
Where does ESRI stand regarding this idea ? It's been 13 years since the creation of this post and .sld style format would still be very useful.
In our case, we are migrating from QGis to ArcGIS Pro, and doing so we need to visualize large sets of data with a lot of different categories within one symbology. The inability to import .sld created from Qgis is holding back the full migration as we don't always have the time to reproduce the entire symbology for each and every dataset we need...
I would definitely like to see this feature from interoperability standpoint, but seeing this idea is already many years old I'm a bit skeptical if they every will get to it.
Getting the official set of styling rules for a layer is really important. SLD has been a standard for styling for several years and public institutions in Europe are using SLD to distribute those styles, both as files directly from there platforms and as a service through WMS get style function. It would be huge if ArcGIS Pro goes forward this way and makes it easy for users to get the official styles distributed by the authorities
