What are KML files?

Keyhole Markup Language (KML) is a file format used to display geographic data in an earth browser, such as Google Earth, Google Maps, and Google Maps for mobile. A KML file is processed in much the same way that HTML (and XML) files are processed by web browsers. Like HTML, KML has a tag-based structure with names and attributes used for specific display purposes. Thus, Google Earth and Maps act as browsers for KML files.

What are SHAPE files?

The Esri Shapefile or simply a shapefile is a popular geospatial vector data format for geographic information systems software. It is developed and regulated by Esri as a (mostly) open specification for data interoperability among Esri and other software products.

2020 Census Redistricting [P.L. 94-171] Tiger/Line Shapefiles

TIGER/Line© Shapefiles are spatial extracts from the Census Bureau's MAF/TIGER database, containing features such as roads, railroads, rivers, as well as legal and statistical geographic areas.

TIGER/Line© Shapefiles are designed for use with geographic information system (GIS) software. The TIGER/Line Shapefiles© do not include demographic data, but they contain geographic entity codes that can be linked to the Census Bureau's demographic data.

The 2020 TIGER/Line© Shapefiles for Pennsylvania can be downloaded from the U.S. Census Bureau's website.
