Polygons with WKT extension load extremely slow
Geographic Information Systems Asked on May 31, 2021
I am quite new to QGIS. I have temporal data per month for the period of 8 years for all Indian districts (+/- 650 districts). This means I have approx. 65.000 objects in my attributes table. Once I upload my file as a layer (a text delimited file) in QGIS using WKT-text, the polyons load extremely slow.
Is there anything I can do about this? I would ultimately like to use the time-manager to visualize my temporal data on India.
One Answer
You can speed up CSVs by using the spatial index as stated at QGIS user manual within this chapter.
However, as already stated in comments, using another file format or especially a spatial database like PostGIS can have more effect.
