How to find the start and end points of a polyline?
For the Type, you will want to choose START/END POINTS. This will create a new point feature class that contains the start and end points for each polyline. The output point feature class will also have a field called LineOID, which records the OID of the polyline it was created from.
How to find the start and end points of a line?
Use ST_EndPoint for endpoints. There is a QGIS plugin “Locate points along lines”. To derive start and endpoints choose Add endpoints an use an Interval longer than your longest line. For an ArcGIS solution, I’ve made a geoprocessing tool that creates points on lines.
How to create a point on a line?
Use ST_EndPoint for endpoints. There is a QGIS plugin “Locate points along lines”. To derive start and endpoints choose Add endpoints an use an Interval longer than your longest line. For an ArcGIS solution, I’ve made a geoprocessing tool that creates points on lines. You can download it, and view the code here: Create Points on Lines
How to change starting point position in lwpolyline?
If you need to change starting point position, you should consider transforming 3D point from 3D space to LWPOLYLINE plane and then use those coordinates to change first DXF GC 10 of entity data of LWPOLYLINE…

How to find the end of a line?
The first vertex corresponds to an index of 0, the second vertex has an index of 1, etc. Negative indices can be used to find vertices at the end of the geometry, e.g., an index of -1 corresponds to the last vertex, -2 corresponds to the second last vertex, etc.
How to extract the start and end points of a vector file?
QGIS solution: It is possible to extract begin and ending nodes (coordinates) of a line vector file, simply by using xat and yat in the field calculator, with the respective indices 0 (start) and -1 (end). That is an one-liner for GDAL. This command creates a shapefile from the start nodes with selected attributes:
How to convert polylines to points in ArcPy?
Then you can convert your polylines’ vertices to point features as suggested Darren Cope and artwork21. If you prefer to do it in ArcMap take a look at Creating new points along a line help topic. As Darren Cope has suggested, converting your layer to a point vertices may be done using the Feature Vertices to Points tool.
