How can I split a (poly)line in segments of a given length in cartodb?
I want to be able to visualize segments of street, each 4m long, following the road curve. One way would have been to trace the road side with a line and then cut it in chunks of 4m.
I cannot use a simple "grid", as the 4m have to be tangent to the path, and I did not find a way to create points or lines with a given distance of each other.
It seems possible in QGIS and OpenJump (How to split a line every x meters?) but I cannot find a way to do it in cartodb.
