[JPP-Devel] Perfomance-tips for large vector-layers?

2010-08-18 Thread Nils Kuhn
Hi, unfortunatily, I have to work with some very large vector-layers at the moment (more than 800.000 polygons in some shape-files). I have to select features by attribute, write some selections to new layers, union features by attribute, etc. (classical GIS-tasks). That's actually no fun! Has

Hi, OpenJUMP is doing all the work in the memory so if you are going to keep all the data open in OpenJUMP then the question is mostly about what is the fastest format to open. Probably shapefiles are. But it is not allways necessary to keep all the data open and for some part of your work

Nils, you might try looking at JEQL to do this. http://tsusiatsoftware.net/jeql/main.html It's based on the same geometry library as OJ (JTS), and is probably a little more suited to running batch operations on large datafiles. Feel free to contact me directly for more info. Martin Nils Kuhn
