geofileops.LayerInfo

class geofileops.LayerInfo(name: str, featurecount: int, total_bounds: Tuple[float, float, float, float], geometrycolumn: str, geometrytypename: str, geometrytype: GeometryType, columns: Dict[str, ColumnInfo], fid_column: str, crs: Optional[CRS], errors: List[str])

A data object containing meta-information about a layer.

name

the name of the layer.

Type:

str

featurecount

the number of features (rows) in the layer.

Type:

int

total_bounds

the bounding box of the layer: (minx, miny, maxx, maxy).

Type:

Tuple[float, float, float, float]

geometrycolumn

name of the column that contains the primary geometry.

Type:

str

geometrytypename

the geometry type name of the geometrycolumn. The type name returned is one of the following: POINT, MULTIPOINT, LINESTRING, MULTILINESTRING, POLYGON, MULTIPOLYGON, COLLECTION.

Type:

str

geometrytype

the geometry type of the geometrycolumn.

Type:

GeometryType

columns

the columns (other than the geometry column) that are available on the layer with their properties as a dict.

Type:

dict

fid_column

column name of the FID column. Is “” for file types that don’t explicitly store an FID, like shapefile.

Type:

str

crs

the spatial reference of the layer.

Type:

pyproj.CRS

errors

list of errors in the layer, eg. invalid column names,…

Type:

List[str]

__init__(name: str, featurecount: int, total_bounds: Tuple[float, float, float, float], geometrycolumn: str, geometrytypename: str, geometrytype: GeometryType, columns: Dict[str, ColumnInfo], fid_column: str, crs: Optional[CRS], errors: List[str])

Constructor of Layerinfo.

Parameters:

• name (str) – name of the layer.

• featurecount (int) – number of features in the layer.

• total_bounds (Tuple[float, float, float, float]) – the bounds of the layer.

• geometrycolumn (str) – the name of the geometry column.

• geometrytypename (str) – the name of the geometry column type.

• geometrytype (GeometryType) – the type of the geometry column.

• columns (Dict[str, ColumnInfo]) – the attribute columns of the layer.

• fid_column (str) – the name of the fid column.

• crs (Optional[pyproj.CRS]) – the crs of the layer.

• errors (List[str]) – errors encountered reading the layer info.
