fionautil
~~~~~~~~~

Utilities for working with geodata with
`Fiona <https://pypi.python.org/pypi/Fiona/1.5.0>`__. Some features are
shorthand for `pyproj <https://pypi.python.org/pypi/pyproj>`__ features,
or add in support for projections.

By defauly, the only prerequisites are ``pyproj`` and Fiona itself.

By default, the package installs without shapely. A small number of
functions, marked below, do require shapely. To use these function,
install with ``pip install fionautil[functionname]`` or just separately
install shapely.

Contents
--------

feature
~~~~~~~

-  overlaps
-  field\_contains\_test (test if a feature's properties has certain
   key:value pairs)
-  togeojson (return a geojson-ready object)
-  shapify (requires shapely)
-  length (requires shapely)
-  compound

geometry
~~~~~~~~

-  endpoints (for polyline features)
-  startpoint (for polyline features)
-  endpoint (for polyline features)
-  bbox
-  azimuth (between the start and end of a polyline)
-  disjointed
-  explodepoints
-  explodesegments
-  exploderings
-  countpoints
-  countsegments
-  roundgeometry - round all coordinates in a geometry to a given
   precision

layer
~~~~~

Most of these tools that mimic builtin python itertools.

-  ffilter
-  ffilterfalse
-  fmap
-  fchain
-  freduce
-  fslice
-  fzip
-  length Total length of linear features in a file's native projection
   or the given Proj object
-  meta (returns a layer's meta attribute)
-  meta\_complete (returns the meta attribute with addional metadata,
   e.g. bounds)
-  bounds (returns a layer's bounds)
-  find (return a feature that matches a particular key=value)

measure
~~~~~~~

-  distance (between two coordinates)
-  azimuth (between two coordinates)
-  signed\_area
-  clockwise (shortcut for checking if signed\_area is >= 0)
-  counterclockwise (shortcut for checking if signed\_area is < 0)
-  azimuth\_distance (returns both azimuth and distance between two
   points)
-  intersect (check if two planar line segments intersect)
-  onsegment (check if a point lines on a line segment)

round
~~~~~

-  geometry - round all coordinates in a geometry to a specified
   precision
-  feature

scale
~~~~~

Utilities for scaling a feature or geometry by a given constant. Goes
faster with Numpy installed. \* geometry \* scale\_rings \* scale -
scales a list of coordinates \* feature - scale the geometry of a
feature
