Metadata was imported into a format viewable by ArcCatalog.
Feature data was standardized to an ESRI shapefile format with naming convention of AGENCY(or)STATEYYYYMMDD where date is idicative of the date imported to the new SMA layer.
Run ARCTOOLBOX model which processes the data from source to SMA layer. Processes in the model include: Reproject to GCS NAD83 projection using NADCON geographic transformation when needed. Standardize and populate attributes based on classification rules defined in the model. Append source to SMA layer, populating ARCHIVE_ID if appropriate.
All polygons with an area less than 0.1 acres were deleted. 0.1 of an acre is about a 21 ft. by 21 ft. area and is seen as negligible. This was performed on all data after the acreage calculation.
ArcToolBox 'Check Geometry' tool used on data. If any errors, use ArcToolBox 'Repair Geometry' tool on data.
ArcToolBox 'Multi part to Single part' tool used on data. This broke up the multipart polygons into single part polygons.
Data is reprojected into USGS ALBERS Equal Area. A new 'Acres' field is added to attributes. The acres for each polygon is calculated.
A new 'name' field is added to attributes. The name is set to a concatenation of unit_name and unit_type.
A new feature class is created using the attributes from the SMA schema as a template. The NPS data is loaded into the new feature class. The attributes that are carried over are: name -> name acres -> acres unit_type -> label1
