Name: Coal Mines by County

Display Field: state_name

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: CoalMine_All_County is aggregated at the County-level for all input mine points according to the county and state designated in the input data. The script starts by installing essential Python packages to handle spatial and non-spatial data. It then imports coal mine data and integrates it with spatial data from the U.S. Census Bureau. A significant feature of the script is the spatial join process, aligning coal mine data with geographical areas of census tracts and counties. The script filters the data based on mine status, identifying active, abandoned, and problematic mines (due to missing or invalid geographic coordinates). It then aggregates the data, compiling counts of mines and associated employment figures. The script distinguishes between valid and problematic data, ensuring accurate spatial analysis. The output is organized into detailed spatial layers, formatted as CSV and GeoPackage files, encompassing aggregated information on active and abandoned coal mines at the county and census tract levels.Calculations:The script computes several key metrics related to coal mines. It calculates the total count of active and abandoned coal mines, as well as the sum of employed individuals in these mines, both at the county and census tract levels. For abandoned mines, the script aggregates counts by the year of abandonment, providing a temporal dimension to the analysis. These aggregations include spatial attributes like State, County, and Census Tract names, alongside geographical identifiers such as GEOID. In processing problematic data entries, the script filters out mines with missing or invalid geographical coordinates, ensuring the accuracy of spatial joins and subsequent analyses. These calculations are pivotal in generating a comprehensive and detailed understanding of the spatial distribution and status of coal mines across different geographical areas.

It includes such information as the current status of each mine (Active, Abandoned, NonProducing, etc.), the current owner and operating company, commodity codes and physical attributes of the mine. Mine ID is the unique key for this data.
