By voting up you can indicate which examples are most useful and appropriate. Shapely is a powerful and versatile one page WordPress theme with pixel perfect design and outstanding functionality. Python has a specific module called Shapely for doing various geometric operations. Python is a really handy tool to solve this problem as with Python it is basically possible to read data from any kind of input datafile (such as csv-, txt-, excel-, or gpx-files (gps data) or from different databases). Dilating a line The pyshp library's sole purpose is to work with shapefilesâit only uses the Python standard library. ⦠This document explains how to use Rasterio to read existing files and to create new files.
