I'm doing a GIS project[1] for fun to find out where I want to move in the next year. I have to constantly monitor RAM usage and save before running some operations because there's a chance OOM killer makes a fatal decision to kill the program. This is on a machine with 32GB and I could easily find myself using more.
1. Using QGIS. It's the first real GIS project I've done. I'm using to do this sort of work in code, so it's been a fun learning experience too.
- brailsafe 4y agoGIS can be hungry, but QGIS is incredible for what it is. Is there a remote sensing component to your project? Satellite tiffs are... big
- kelseyfrog 4y agoFor sure! And yes parts of it involve raster data. It doesn't help that I have very little control over the raster internals. My project is limited to NY,OR,WA, but this clearly has a potential sparse raster problem. If I was doing it in code, I'd reach for internally tiled cloud-optimized geotiffs with low compression and I'd be pretty sure that all the empty tiles would get compressed down to nothing. With QGIS, I can cross my fingers and hope it's doing something relatively sane with GDAL in the background.
