示例1: Point
# 需要导入模块: from shapely.geometry import Point [as 别名]
# 或者: from shapely.geometry.Point import idx [as 别名]
shapePoints = []
circleRadius = random.randint(500, 1500)
circleX = random.randint(0, gridWidth)
circleY = random.randint(0, gridHeight)
sCircle = Point(circleX, circleY)
sCircle = sCircle.buffer(circleRadius, 16)
pointList = []
for i in range(numberOfPoints):
x = random.randint(0, gridWidth)
y = random.randint(0, gridHeight)
pointList.append((x, y))
iPoint = Point(x, y)
iPoint.idx = i # set our custom attribute. (if this doesnt work I have other ways)
shapePoints.append(iPoint)
matchingPoints = []
searchBench = time.time()
for idx, point in enumerate(shapePoints):
if sCircle.contains(point):
matchingPoints.append(idx)
searchBench = time.time() - searchBench
print "There were %d points within the circle [%d, %d] - r[%d]\n" % (len(matchingPoints), circleX, circleY, circleRadius)
print "Calculation Took %s seconds for %s points" % (searchBench, numberOfPoints)
print "Saving Graph to %s" % (filename)
示例2: Point
# 需要导入模块: from shapely.geometry import Point [as 别名]
# 或者: from shapely.geometry.Point import idx [as 别名]
'''
Because shapely api objects are in fact objects we should be able to set
arbitrary properties on the objects. This is useful if you want the shapely
object to relate back to a OBJECT_ID or an arbitrary index that references
the object the geometric point/object corresponds to.
'''
from shapely import *
from shapely.geometry import Point
myPoint = Point(1.2, 3.0)
myPoint.idx = 'custom_idx'
# Performing operations that creates a new object or modifies the object will
# cause your custom attribute to be lost...
circle = myPoint.buffer(3.0, 16)
circle.idx = myPoint.idx
print circle.idx
