Is Tiger/Line 2010 Data Inaccurate? What’s more reliable?

Is nominatim reliable?

On average Nominatim does great job and correctly geocodes around 70% of addresses, while best commercial services can geocode around 90%.
 

What agency creates and maintains Tiger Files?

The TIGER/Line Shapefiles are the fully supported, core geographic product from the U.S. Census Bureau. They are extracts of selected geographic and cartographic information from the U.S. Census Bureau’s Master Address File/Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) database.

What is Tiger Geocoder?

Tiger Geocoder is a plpgsql-based fully-functional geocoder that can process an arbitrary address string and, using normalized TIGER census data, produce a point geometry and rating reflecting the location of the given address and likeliness of the location.
 

How reliable is OpenStreetMap?

The accuracy varies across the map, with general shapes being quite accurate, but distortions evident, especially where there is poor line of sight, which made triangulation difficult. Old maps should be used with caution.

Where do TIGER files come from?

TIGER (Topologically Integrated Geographic Encoding and Referencing) files come from the US Census Bureau. TIGER files contain information about many different features such as roads, rivers, lakes, political boundaries (state, county), and census boundaries (Block, Block Group, Census Tract).

Who creates the TIGER files?

the Census Bureau

Every 1-3 years the Census Bureau creates an extract from this data base and releases a TIGER update. These extracts are known as TIGER/Line files.

Who developed TIGER data?

The convenience of getting directions today on smartphones and tablets can trace its roots to the digital geographic database created 25 years ago by the U.S. Census Bureau.
 

How accurate is geocoding?

Compared with the reference method, the two methods of geocoding gave similar results in terms of general accuracy, with more than 60% of addresses geocoded to the exact address level, and more than 15% to the street segment level.
 

Is Mapbox reliable?

Highly performant, customizable, reliable, and scalable, Mapbox location services are trusted by leaders in industries spanning automotive, logistics, business intelligence, retail, travel, data visualization, consumer apps, weather, IoT, geospatial analysis, and beyond.

Where does OpenStreetMap get its data?

OpenStreetMap (OSM) is a free, open geographic database updated and maintained by a community of volunteers via open collaboration. Contributors collect data from surveys, trace from aerial imagery and also import from other freely licensed geodata sources.
