It is based on the widely deployed `GEOS 34 <https://trac.osgeo.org/geos/>`__ (the engine of `PostGIS 35 <http://postgis.org>`__) and `JTS 36 <https://locationtech.github.io/jts/>`__ (from which GEOS is ported) 37 libraries. Shapely is not concerned with data formats or coordinate systems, 38 but can be readily integrated with packages that are. For more details, see: 39 40 * `Shapely GitHub repository <https://github.com/Toblerity/Shapely>`__ 41 * `Shapely documentation and manual <https://shapely.readthedocs.io/en/latest/>`__ 42 43 Usage 44 ===== 45 46 Here is the canonical example of building an approximately circular patch by 47 buffering a point. 48 49 .. code-block:: pycon 50 51 >>> from shapely.geometry import Point 52 >>> patch = Point(0.0, 0.0).buffer(10.0) 53 >>> patch 54 <shapely.geometry.polygon.Polygon object at 0x...> 55 >>> patch.area 56 313.65484905459385 57 58 See the manual for more examples and guidance. 59 60 Requirements 61 ============ 62 63 Shapely 1.8 requires 64 65 * Python >=3.6 66 * GEOS >=3.3 67 68 Installing Shapely 69 ================== 70 71 Shapely may be installed from a source distribution or one of several kinds 72 of built distribution. 73 74 Built distributions 75 ------------------- 76 77 Built distributions are the only option for users who do not have or do not 78 know how to use their platform's compiler and Python SDK, and a good option for 79 users who would rather not bother. 80 81 Linux, OS X, and Windows users can get Shapely wheels with GEOS included from the 82 Python Package Index with a recent version of pip (8+): 83 84 .. code-block:: console 85 86 $ pip install shapely 87 88 Shapely is available via system package management tools like apt, yum, and 89 Homebrew, and is also provided by popular Python distributions like Canopy and 90 Anaconda. If you use the Conda package manager to install Shapely, be sure to 91 use the conda-forge channel. 92 93 Windows users have another good installation options: the wheels published at 94 https://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely. These can be installed 95 using pip by specifying the entire URL. 96 97 Source distributions 98 -------------------- 99 100 If you want to build Shapely from source for compatibility with other modules 101 that depend on GEOS (such as cartopy or osgeo.ogr) or want to use a different 102 version of GEOS than the one included in the project wheels you should first 103 install the GEOS library, Cython, and Numpy on your system (using apt, yum, 104 brew, or other means) and then direct pip to ignore the binary wheels. 105 106 .. code-block:: console 107 108 $ pip install shapely --no-binary shapely 109 110 If you've installed GEOS to a standard location, the geos-config program will 111 be used to get compiler and linker options. If geos-config is not on your 112 executable, it can be specified with a GEOS_CONFIG environment variable, e.g.: 113 114 .. code-block:: console 115 116 $ GEOS_CONFIG=/path/to/geos-config pip install shapely 117 118 Integration 119 =========== 120 121 Shapely does not read or write data files, but it can serialize and deserialize 122 using several well known formats and protocols. The shapely.wkb and shapely.wkt 123 modules provide dumpers and loaders inspired by Python's pickle module. 124 125 .. code-block:: pycon 126 127 >>> from shapely.wkt import dumps, loads 128 >>> dumps(loads('POINT (0 0)')) 129 'POINT (0.0000000000000000 0.0000000000000000)' 130 131 Shapely can also integrate with other Python GIS packages using GeoJSON-like 132 dicts. 133 134 .. code-block:: pycon 135 136 >>> import json 137 >>> from shapely.geometry import mapping, shape 138 >>> s = shape(json.loads('{"type": "Point", "coordinates": [0.0, 0.0]}')) 139 >>> s 140 <shapely.geometry.point.Point object at 0x...> 141 >>> print(json.dumps(mapping(s))) 142 {"type": "Point", "coordinates": [0.0, 0.0]} 143 144 Development and Testing 145 ======================= 146 147 Dependencies for developing Shapely are listed in requirements-dev.txt. Cython 148 and Numpy are not required for production installations, only for development. 149 Use of a virtual environment is strongly recommended. 150 151 .. code-block:: console 152 153 $ virtualenv . 154 $ source bin/activate 155 (env)$ pip install -r requirements-dev.txt 156 (env)$ pip install -e . 157 158 The project uses pytest to run Shapely's suite of unittests and doctests. 159 160 .. code-block:: console 161 162 (env)$ python -m pytest 163 164 Support 165 ======= 166 167 Questions about using Shapely may be asked on the `GIS StackExchange 168 <https://gis.stackexchange.com/questions/tagged/shapely>`__ using the "shapely" 169 tag. 170 171 Bugs may be reported at https://github.com/Toblerity/Shapely/issues. 172 173 174 Credits 175 =======

There have been no changes since 1.8rc2. 322 323 1.8rc2 (2021-10-19) 324 ------------------- 325 326 Build: 327 328 A pyproject.toml file has been added to specify build dependencies for the 329 _vectorized and _speedups modules (#1128). To install shapely without these 330 build dependencies, use the features of your build tool that disable PEP 517 331 and 518 support. 332 333 Bug fixes: 334 335 - Part of PR #1042, which added a new primary GEOS library name to be searched 336 for, has been reverted by PR #1201. 337 338 1.8rc1 (2021-10-04) 339 ------------------- 340 341 Deprecations: 342 343 The almost_exact() method of BaseGeometry has been deprecated. It is confusing 344 and will be removed in 2.0.0. The equals_exact() method is to be used instead. 345 346 Bug fixes: 347 348 - We ensure that the _speedups module is always imported before _vectorized to 349 avoid an unexplained condition on Windows with Python 3.8 and 3.9 (#1184). 350 351 1.8a3 (2021-08-24) 352 ------------------ 353 354 Deprecations: 355 356 The STRtree class deprecation warnings have been removed. The class in 2.0.0 357 will be backwards compatible with the class in 1.8.0. 358 359 Bug fixes: 360 361 - The __array_interface__ raises only AttributeError, all other exceptions are 362 deprecated starting with Numpy 1.21 (#1173). 363 - The STRtree class now uses a pair of item, geom sequences internally instead 364 of a dict (#1177). 365 366 367 1.8a2 (2021-07-15) 368 ------------------ 369 370 Python version support: 371 372 Shapely 1.8 will support only Python versions >= 3.6. 373 374 New features: 375 376 - The STRtree nearest*() methods now take an optional argument that 377 specifies exclusion of the input geometry from results (#1115). 378 - A GeometryTypeError has been added to shapely.errors and is consistently 379 raised instead of TypeError or ValueError as in version 1.7. For backwards 380 compatibility, the new exception will derive from TypeError and Value error 381 until version 2.0 (#1099). 382 - The STRtree class constructor now takes an optional second argument, a 383 sequence of objects to be stored in the tree. If not provided, the sequence 384 indices of the geometries will be stored, as before (#1112). 385 - The STRtree class has new query_geoms(), query_items(), nearest_geom(), and 386 nearest_item() methods (#1112). The query() and nearest() methods remain as 387 aliases for query_geoms() and nearest_geom(). 388 389 Bug fixes: 390 391 - We no longer attempt to load libc to get the free function on Linux, but get 392 it from the global symbol table. 393 - GEOS error messages printed when GEOS_getCoordSeq() is passed an empty 394 geometry are avoided by never passing an empty geometry (#1134). 395 - Python's builtin super() is now used only as described in PEP 3135 (#1109). 396 - Only load conda GEOS dll if it exists (on Windows) (#1108). 397 - Add /opt/homebrew/lib to the list of directories to be searched for the GEOS 398 shared library. 399 - Added new library search path to assist app creation with cx_Freeze. 400 401 1.8a1 (2021-03-03) 402 ------------------ 403 404 Shapely 1.8.0 will be a transitional version. There are a few bug fixes and new 405 features, but it is mainly about warning of the upcoming changes in 2.0.0. 406 Several more pre-releases before 1.8.0 are expected. See the migration guide 407 to Shapely 1.8 / 2.0 for more details on how to update your code 408 (https://shapely.readthedocs.io/en/latest/migration.html). 409 410 Python version support: 411 412 Shapely 1.8 will support only Python versions >= 3.5 (#884). 413 414 Deprecations: 415 416 The following functions and geometry attributes and methods will be removed in 417 version 2.0.0. 418 419 - ops.cascaded_union 420 - geometry .empty() 421 - geometry .ctypes and .__array_interface__ 422 - multi-part geometry .__len__ 423 - setting custom attributes on geometry objects 424 425 Geometry objects will become immutable in version 2.0.0. 426 427 The STRtree class will be entirely changed in 2.0.0. The exact future API is 428 not yet decided, but will be decided before 1.8.0 is released. 429 430 Deprecation warnings will be emitted in 1.8a1 when any of these features are 431 used. 432 433 The deprecated .to_wkb() and .to_wkt() methods on the geometry objects have 434 been removed. 435 436 New features: 437 438 - Add a normalize() method to geometry classes, exposing the GEOSNormalize 439 algorithm (#1090). 440 - Initialize STRtree with a capacity of 10 items per node (#1070). 441 - Load libraries relocated to shapely/.libs by auditwheel versions < 3.1 or 442 relocated to Shapely.libs by auditwheel versions >= 3.1. 443 - shapely.ops.voronoi_diagram() computes the Voronoi Diagram of a geometry or 444 geometry collection (#833, #851). 445 - shapely.validation.make_valid() fixes invalid geometries (#883) 446 447 Bug fixes: 448 449 - For pyinstaller we now handle the case of more than one GEOS library in the 450 environment, such as when fiona and rasterio wheels are co-installed with 451 shapely (#1071). 452 - The ops.split function now splits on touch to eliminate confusing 453 discrepancies between results using multi and single part splitters (#1034). 454 - Several issues with duplication and order of vertices in ops.substring have 455 been fixed (#1008). 456 457 Packaging: 458 459 - The wheels uploaded to PyPI will include GEOS 3.9.1. 460 461 1.7.1 (2020-08-20) 462 ------------------ 463 464 - ``STRtree`` now safely implements the pickle protocol (#915). 465 - Documentation has been added for ``minimum_clearance`` (#875, #874). 466 - In ``STRtree.__del__()`` we guard against calling ``GEOSSTRtree_destroy`` 467 when the lgeos module has already been torn down on exit (#897, #830). 468 - Documentation for the ``overlaps()`` method has been corrected (#920). 469 - Correct the test in ``shapely.geometry.base.BaseGeometry.empty()`` to 470 eliminate memory leaks like the one reported in #745. 471 - Get free() not from libc but from the processes global symbols (#891), 472 fixing a bug that manifests on OS X 10.15 and 10.16. 473 - Extracting substrings from complex lines has been made more correct (#848, 474 #849). 475 - Splitting of complex geometries has been sped up by preparing the input 476 geometry (#871). 477 - Fix bug in concatenation of function argtypes (#866). 478 - Improved documentation of STRtree usage (#857). 479 - Improved handling for empty list or list of lists in GeoJSON coordinates 480 (#852). 481 - The polylabel algorithm now accounts for polygon holes (#851, #817). 482 483 1.7.0 (2020-01-28) 484 ------------------ 485 486 This is the final 1.7.0 release.

Please note that ``asShape`` is likely to be deprecated in a future 589 version of Shapely. 590 - Check for length of LineString coordinates in speed mode, preventing crashes 591 when using LineStrings with only one coordinate (#546). 592 593 1.6.2 (2017-10-30) 594 ------------------ 595 596 - A 1.6.2.post1 release has been made to fix a problem with macosx wheels 597 uploaded to PyPI. 598 599 1.6.2 (2017-10-26) 600 ------------------ 601 602 - Splitting a linestring by one of its end points will now succeed instead of 603 failing with a ``ValueError`` (#524, #533). 604 - Missing documentation of a geometry's ``overlaps`` predicate has been added 605 (#522). 606 607 1.6.1 (2017-09-01) 608 ------------------ 609 610 - Avoid ``STRTree`` crashes due to dangling references (#505) by maintaining 611 references to added geometries. 612 - Reduce log level to debug when reporting on calls to ctypes ``CDLL()`` that 613 don't succeed and are retried (#515). 614 - Clarification: applications like GeoPandas that need an empty geometry object 615 should use ``BaseGeometry()`` instead of ``Point()`` or ``Polygon()``. An 616 ``EmptyGeometry`` class has been added in the master development branch and 617 will be available in the next non-bugfix release. 618 619 1.6.0 (2017-08-21) 620 ------------------ 621 622 Shapely 1.6.0 adds new attributes to existing geometry classes and new 623 functions (``split()`` and ``polylabel()``) to the shapely.ops module. 624 Exceptions are consolidated in a shapely.errors module and logging practices 625 have been improved. Shapely's optional features depending on Numpy are now 626 gathered into a requirements set named "vectorized" and these may be installed 627 like ``pip install shapely[vectorized]``. 628 629 Much of the work on 1.6.0 was aimed to improve the project's build and 630 packaging scripts and to minimize run-time dependencies. Shapely now vendorizes 631 packaging to use during builds only and never again invokes the geos-config 632 utility at run-time. 633 634 In addition to the changes listed under the alpha and beta pre-releases below, 635 the following change has been made to the project: 636 637 - Project documentation is now hosted at 638 https://shapely.readthedocs.io/en/latest/. 639 640 Thank you all for using, promoting, and contributing to the Shapely project. 641 642 1.6b5 (2017-08-18) 643 ------------------ 644 645 Bug fixes: 646 647 - Passing a single coordinate to ``LineString()`` with speedups disabled now 648 raises a ValueError as happens with speedups enabled.
