Shapefile — Parcels Attributes (.dbf)
The parcel attribute table, joined to the .shp purely by record order — there is no key and no explicit link. Deleting a geometry without deleting its row shifts every subsequent attribute onto the wrong shape, silently.

Testing contract
Expected to pass- Scenario
- Join the attributes to the geometry and verify that row order still matches record order.
- Expected result
- Row 2 (Mill Court) pairs with the two-ring polygon; the join is positional, so any reordering of either file is detectable as a mismatch.
What is a .dbf file?
A dBASE table (.dbf) is a legacy binary tabular format with a fixed-width header describing columns (name, type, length) followed by fixed-length records. It persists today as the attribute table of GIS shapefiles and in legacy database exchange.
How to use this file
Use an example .dbf file to test dBASE/xBase readers, shapefile attribute parsing, and DBF-to-CSV conversion.
How to use this file for testing
“Shapefile — Parcels Attributes (.dbf)” is a deterministic Novus Examples fixture for Geospatial, Data import, Serialization testing. GeoJSON, GPX, and KML files with points, lines, polygons, and tracks — for testing map tools, route parsers, and geo importers.
Documented properties for this file: 3 records · 4 fields · Esri shapefile component. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
Geospatial fixtures publish one invented territory across formats, with the coordinate reference system and feature counts documented in specs. Convert or reproject and diff against the twin in the same group; edge-case geometries state exactly which assumption they are built to break.

- dbfShapefile — Roads Attributes (.dbf with a decimal field)The road attribute table, including a numeric field declared with two decimal places. DBF stores numbers as right-justified ASCII, so the declared width and decimal count are the only thing that says 9.40 is not 940.
- dbfShapefile — Towns Attributes (.dbf, dBase III)The attribute table as a dBase III file: fixed-width, space-padded, ASCII numerics. Field names are capped at ten characters and there is no type for dates-with-time or for nested values, which is why shapefile export loses so much of a modern schema.
- shpShapefile — Roads Geometry (.shp, 3 PolyLine records)Three single-part PolyLine records, each carrying its own bounding box, a part index and a run of little-endian coordinate doubles. PolyLine and Polygon share this layout, which is why the shape-type byte in the header is the only thing that distinguishes an open line from a closed ring.
- shxShapefile — Roads Index (.shx)Unlike the point index, these entries have different lengths because each PolyLine holds a different number of vertices. That makes it the useful case for testing seek logic — a reader that assumes a fixed stride reads the first record correctly and then garbage.
- shpShapefile — Towns Geometry (.shp, 5 Point records)The geometry half of a point shapefile: a 100-byte header carrying the shape type and bounding box, then five 20-byte Point records. The file is useless on its own — attributes live in the .dbf and the coordinate system in the .prj, which is the point of shipping the whole component set.
- shxShapefile — Towns Index (.shx)The index that lets a reader seek directly to record N of the .shp instead of walking the file. Its header duplicates the .shp header exactly, and a mismatch between the two is the most common way a hand-edited shapefile goes wrong.
