How are the points in a shapefile split?
I’m trying to split a shapefile of geometry type ‘line’ at a shapefile of geometry type ‘point. These points are snapped to the lines and are the start points/end points of other line shapefiles. Something like this : The points are snapped to the black lines.
How to split lines in a geoprocessing tool?
This is odd since the split is among the basic geoprocessing tools. My goal is to give a function of the two shapefiles (lines & points) and split the lines at points (like ArcGIS’ tool). The split lines should then be stored in a different shapefile. This seems easy to do but the lack of documentation is a bump in the road.
Is it possible to split lines in shapely?
This is also true when searching through Shapely’s official docs. This is odd since the split is among the basic geoprocessing tools. My goal is to give a function of the two shapefiles (lines & points) and split the lines at points (like ArcGIS’ tool). The split lines should then be stored in a different shapefile.
How are the points snapped to the lines?
These points are snapped to the lines and are the start points/end points of other line shapefiles. Something like this : The points are snapped to the black lines. As of now I’m working with Geopandas/Shapely/Fiona. I’ve searched for a native function in Shapely that performs the split; however, I’ve had no luck in finding a solution.
How to write shapely geometries to shapefiles?
Here is a very simple example of using them together to “clean” shapefile features: From https://github.com/Toblerity/Fiona/blob/master/examples/with-shapely.py. You can also write Shapely geometries by using PyShp (since the original poster also asked about PyShp).
How to create a shapefile object in Python?
After the initial comment block and library import, the code reads in the shapefile using the string variables that give the location of the shapefile directory (data_dir) and the name of the shapefile without extension (shp_file_base): This creates a shapefile object, sf, and the next few lines do some basic inspections of that object.
