: These files contain selected geographic and cartographic information (roads, boundaries, water features) from the Master Address File/Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) database.
While this specific filename appears in specialized data repositories, its structure suggests it belongs to one of the following two domains: 1. U.S. Census Bureau TIGER/Line Shapefiles Tir_Al_2021-09_to_2021-12.zip
: Check for a README.md or metadata.xml file within the zip to confirm the specific geographic region or dataset version. Loading : For GIS : Open the .shp file in QGIS or ArcMap . : These files contain selected geographic and cartographic
: Once extracted, the .zip will contain multiple files including .shp , .shx , and .dbf which must be kept together to function correctly. 2. Information Retrieval (IR) Datasets Census Bureau TIGER/Line Shapefiles : Check for a README
The "ir" in the name may also relate to ir_datasets , a common Python library used to download and provide a uniform interface to various IR datasets for research.
: If you are using these for machine learning, you would typically use the ir_datasets Python API or CLI to load the data for document ranking or answer extraction tasks. Guide for Using the Data
: They are typically used in Geographic Information Systems (GIS) software like ArcGIS or QGIS for mapping and spatial analysis.
