Name: NLCS National Monuments, National Conservation Areas and Similar Designations

Display Field: NCA_NAME

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This polygon feature class represents the spatial extent and boundaries of the BLM National Landscape Conservation System (NLCS) National Monuments, National Conservation Areas and Similar Designations. Many of the BLM National Datasets cannot be taken offline due to the number of vertices in the dataset. In addition, displaying the data using a Feature Service crashes ArcGIS Server due to complex geometries (ie Godzilla polygons). As a result, it became imperative to generalize the Feature Classes so that they can be used in a Feature Service as well as being taken offline. Using configuration settings, the user may choose between using a Smoothing algorithm or Simplification algorithm to perform generalization. Documentation on the Smoothing algorithm can be found here: https://pro.arcgis.com/en/pro-app/latest/tool-reference/cartography/smooth-polygon.htm Documentation on the Simplification algorithm can be found here: https://pro.arcgis.com/en/pro-app/latest/tool-reference/cartography/simplify-polygon.htm Note: At the time of this writing, only polygon smoothing/simplification is tested. However, Linear datasets are also supported (FEATURE_TYPE) *Each of the features within this feature class were generalized. To keep the naming convention the same, we added the _gen after each feature class so this service and the data layers won’t get confused with the other NLCS services. This service and the underlying data will be kept “in-sync” with national replication. This polygon feature class represents the spatial extent and boundaries of the BLM National Landscape Conservation System (NLCS) National Monuments, National Conservation Areas and Similar Designations. This dataset is a subset of the official national dataset, containing features and attributes intended for public release and has been optimized for online map service performance.

The Implementation Guide represents the official national dataset from which this dataset was derived.
