The absolute maximum any component can be is 2GB... merging, adding or editing datasets this large I would strongly advise against as they are prone to corruption and when that happens you will loose all your work. You could do OGR2OGR using a clpsrc to extract the area. | |
| Jul 28, 2014 at 20:29 | comment | added | Vince | 1Gb isn't all that descriptive, since the width of the dBase file record width is going to be the major determinate in how many features this represents (assuming the 4000 byte record limit is honored, the limit ranges from 25+ million features to ~250k features). With a three order of magnitude range, knowing the rough order of magnitude on the feature count would be useful. | |
