Optimized :func:`accordion ` algorithm. #. Optimized :func:`schematization ` algorithm. #. Optimized :func:`inflexion_points ` algorithm. - **Bug Fixes**: #. Fixed the :func:`collapse_dual_carriageways ` algorithm to treat polygons connected by their short side. #. Fixed the :func:`LeastSquaresMethod `, some matrices were wrongly built. 1.0.2 ===== - **New features**: #. Added a new :func:`make_planar ` function that creates a planar network from a provided network and keeps a link between input and output. #. Added a new :func:`strokes_rivers ` function that generate strokes on river networks. - **Improvements**: #. :func:`network_faces ` now returns a list of geometry instead of a GeometrySequence. #. Fixed some inconsistencies within the :func:`dilate_line ` function that caused random issues with the precision of the vertexes coordinates. Now, the function never relies on distances, this is much quicker. Furthermore, wrapped line extremities are now accounted for. #. The point reduction algorithms now returns the full set of provided points with a boolean attribute to know if it was selected. This, of course, is not the case in aggregation mode. Furthermore, point reduction algorithms have been divided into multiple algorithms in order to be more obvious, easy to use. Read more about that on their respective reference page: - :func:`kmeans_selection ` - :func:`kmeans_simplification ` - :func:`kmeans_aggregation ` - :func:`labelgrid_selection ` - :func:`labelgrid_simplification ` - :func:`labelgrid_aggregation ` - :func:`quadtree_selection ` - :func:`quadtree_simplification ` - :func:`quadtree_aggregation ` - **Bug fixes**: #. Fixed an issue in :func:`li_openshaw `. :pr:`14` (:user:`gowestmen`) #. Fixed an issue in :func:`collapse_branching_crossroads ` when splitting a line by a point which causes problems of floating points in Shapely. 1.0.1 ===== - **New features**: #. Added new kernel methods for the :func:`heatmap ` function: epanechnikov, gaussian, uniform and triangular. :pr:`12` (:user:`gowestmen`) - **Improvements**: #. Renamed :func:`detect_pastiness ` to :func:`coalescence_splitting ` to better reflect the usage and litterature. - **Bug fixes**: #. Fixed an issue in the :func:`collapse_branching_crossroads ` function where :func:`linemerge() ` could input a LineString instead of a MultiLineString. 1.0.0 ===== - **New features**: #. Exposed three new functions used inside the network enrichment functions: - :func:`is_roundabout ` - :func:`is_branching_crossroad ` - :func:`is_dual_carriageway ` - **Improvements**: #. All undocumented/unwanted functions are now hidden. #. Removed all circular import inside the library. #. Renamed :class:`Constraint ` to :class:`LeastSquaresMethod ` to better reflect if usage and enhanced its documentation. 1.0rc2 ====== - **New features**: #. Added :func:`li_openshaw ` to simplify lines. (:user:`jberli`) #. Added :func:`square_polygon_naive ` to square polygons. (:user:`jberli`) #. Added :func:`heatmap ` creation. :pr:`8` (:user:`gowestmen`) #. New covering algorithms to create convex and concave hull: - :func:`hull_delaunay ` (:user:`gtouya`) - :func:`hull_swinging_arm ` :pr:`4` (:user:`Vpech77`) #. Added :func:`reduce_labelgrid ` function as a new point reduction method. :pr:`3` :pr:`6` (:user:`Vpech77`) :pr:`9` (:user:`gowestmen`) #. Added :func:`tessellate ` to create a tesselation of a given shape. This method has been taken from :pr:`3` :pr:`6` (:user:`Vpech77`) and wrapped inside a new function. #. Added :func:`partition_grid ` to partition objects using the new tessellations. #. Added :func:`strokes_roads ` (:user:`ACourtial`) function to detect strokes inside a road network. This allows an easy strokes calculation by reducing the number of steps. - **Improvements**: #. Renamed point reduction functions: - :func:`reduce_points_kmeans ` to :func:`reduce_kmeans `. - :func:`reduce_points_quadtree ` to :func:`reduce_quadtree `. #. Every point reduction method, namely :func:`reduce_kmeans `, :func:`reduce_quadtree ` and :func:`reduce_labelgrid ` now takes GeoDataFrame as input and have the same modes available (selection, simplification and aggregation). #. :func:`gaussian_smoothing ` can now treat polygons. #. AGENT rectangle transformation now depends on the minimum rotated rectangle that shares at least one edge with the original rectangle. This allows the resulting rectangle to be more aligned with the original building. - **Bug fixes**: #. Fixed the :func:`morphological_amalgamation ` issues function caused by: - The ``__edge_removal`` function. The function was reworked. - The ``straight_line_intersection`` method of the ``Segment`` class crashed because of the use of the deprecated numpy array method ``itemset``. - The ``Vector2D.from_segment`` method which was fixed. #. Fixed bugs in the network enrichment functions: - :func:`detect_roundabouts ` - :func:`detect_branching_crossroads ` - :func:`detect_dead_ends ` - :func:`detect_dual_carriageways ` - :func:`rural_traffic ` They now return an empty GeoDataFrame if no entity was detected. #. Fixed a bug in :class:`PointSetQuadTree` where negative coordinates could cause problems. 1.0rc1 ====== The first official beta pre-release of CartAGen.
