Long time to load shapefiles
I have a similar spec to yours, with i7 instead. I have successfully read it, but first time it crashed (I think because memory was exhausted). It took about 20min. I would work on subsetting the part you want with an ogr2ogr incantation if you want to stay away from GIS: http://www.gdal.org/ogr2ogr.html QGIS or similar would be able to read / crop this no-sweat, but it depends on exactly how you want to subset it, and that may be a topic for another forum Cheers, Mike On Thu, Oct 17, 2013 at 2:18 AM, philippe massicotte

Hi everyone. I'm trying to open some shapefiles, but the process is still not complete after 25 minutes. Looking at the shapefiles in ArcGIS, I find that these files have roughly 500K entries. I was wondering if this processing time to open the shapefiles is normal. Here is my configuration: Intel i5-2500 @ 3.3 GHz16 GB of RAMWindows 7 (64 bits) For information, you can download the shapefiles here: http://www.usna.edu/Users/oceano/pguth/srtm/rivers.zip Here is my code: library(rgdal)shape=readOGR("af_riv_15s.shp", layer="af_riv_15s") Thank you for your help,Phil [[alternative HTML version deleted]]
