Convert GeoJSON to Feature (polyline) takes ages

WumboB

Hi folks,

I seem to have an issue with importing GeoJSON files to features (polyline) in ArcGIS pro (version 2.9.5). The JSON file is quite large (about 340 MB). I made sure the JSON file is on my local drive such that no netwerk delays are present. Still the import takes something between 8 and 16 hours.

I'm running this one a descent computer (win 10, Intel(R) Core(TM) i7-10850H CPU (6 core with hyper threading), 32 GB of RAM, a descent 1 TB SSD). When looking at the task manager while importing such an GeoJSON file, the CPU is not loaded at all (up to 25%), ArcGIS uses about 2 GB of memory and also the SSD is hardly transfering any data.

Does anyone know what might cause this long import times?

 

Kind regards,

Wumbo

25% load on a 6-core system means that one CPU is fully engaged and another at 50%. Parsing a big text block like that isn't terribly efficient, and could easily suffer from poor performance (though 8-16 hours seems far too long).

How many features, with how many vertices/feature? What exact procedure are you using to convert the data?  Have you tried using Python to load the JSON to a dictionary then processing it from there?
