I have a large txt file with x,y,z format. The file size is almost 8 GB. So I don’t want to process in ArcMAP. What I wanted to do is, I have a end coordinates for polygon shapefile and i have converted that nodes into x min, ymin, x max, y max and I wanted to Clip all the points within that polygon and save a clipped version into a txt file. My point is how I am going to clip a txt file with a bounding polygon?
Can you provide any Python, R and GDAl/ogr2ogr code?
