Metro Data Resource CenterIn August 2012, the the Outdoor Recreation and Conservation Areas (ORCA) feature class replaced RLIS Parks as a considerably richer dataset with more attributes and finer granularity of the features. Though the parcel-specific ORCA layer provided more accurate and precise analysis, it also added some complexity and had proven to be a bit unwieldy to use for cartographic purposes. To address this issue, in 2014, the Data Resource Center created a new ORCA Sites feature class by assigning a unique DissolveID for each site, making it a simple and useful cartographic layer.
