Java Out of Memory Issue

[nb1...@gmail.com]

Hi I'm trying to use this software to map the migration flows of students in the UK.

When I run the code I keep getting the following message 'java.lang.OutOfMemoryError: Java heap space'

Any ideas if this is caused by my computer memory or because my dataset is too large?

Many thanks,

Neil

Hi Neil,

Have you tried giving it more memory? If not, you could try to run the following from Terminal:

java -Xmx1024m -jar jflowmap.jar

Thanks - i can now plot my flows but cannot get the shapefile to display behind them. Is there a maximum file size that flow map can handle? 

Many thanks,

Neil

If it's really too big, you might try to simplify it. Check out http://www.mapshaper.org/
