- Is there a way to slice a polygon using shapely?
Smaller size should give more equal size parts, but will make execution time longer xmin, ymin, xmax, ymax = subframe geometry total_bounds xcoords = np arange(start=xmin, stop=xmax, step=gridsize) ycoords = np arange(start=ymin, stop=ymax, step=gridsize) coordinates = np array(np meshgrid(xcoords, ycoords)) T reshape(-1,2) squares = [shapely
- python - Setting CRS of point using shapely - Geographic Information . . .
Shapely geometries are unaware of their CRS Using pyproj to transform them only changes the values of the coordinates without leaving any trace of the final CRS in the resulting geometries Serializing a shapely geometry to wkb will never write the CRS information
- python - Polygon overlay with Shapely - Geographic Information Systems . . .
I'm trying to capture all the non-overlapping polygons indicated below using Shapely (given polygons A,B C) Moreover, I'm hoping to do so without iteration, testing for intersect etc The accepted answer to this question expresses the PostGIS method but it would seem that 'union' means different things to different people

4) now, using shapely:cascaded_union (or shapely:unary_union) to get a MultiLineString: from shapely ops import cascaded_union mergedradii = cascaded_union(radii) print mergedradii type MultiLineString 5) the same with the original lines (shapefile)
- Difference between Crosses Intersects - Shapely (Python)
From Shapely's doc: intersects() is equivalent to the OR-ing of contains(), crosses(), equals(), touches(), and within() So there might be some cases where two lines intersect eachother without crossing, in particular when one line contains another or when two lines are equals More specifically:
- Working with geographic coordinates in shapely?
I have some geographic coordinates received from a GPS I would like to use shapely to calculate the great cicle distance in meters between two points I started with: >>> from shapely geometry import Point >>> p1 = Point(43 374880, -78 119956) >>> p2 = Point(43 374868, -78 119666)
- shapely - How to access members of GeometryCollection - Python . . .
You've confused the QGIS and Shapely libraries The code in the similar post doesn't apply to Shapely In your case, p = l1 intersection(l2) returns an instance of Shapely's GeometryCollection p[0] is the first part of that collection All you need is: p = l1 intersection(l2) junctions append(p[0])

Your capital_pt is the coords attribute of the original capital shapely geometry object In itself this is not a shapely geometry, rather a sequence of tuples of flots which are the point objects Instead you should be using distance_between_pts = capital distance(city_items)
