I'm in the process of writing some ISL files, and I'm fairly new to this so please forgive me. In creating a data source with the<datasource> tag, is there an attribute to subset the spatial domain? I see the 'times' attribute, but it would be nice to be able to subset the spatial domain, too. I guess I could use jython method to do the loading of a datasource with spatial subsetting, but I like the ease of ISL language and was wondering if spatial subsetting was an option in ISL or if I'm just stuck with jython to do this? Thanks!
There isn't, but it could be easily added by the IDV developers.Here's something that should work. On your IDV invocation where you pass in the isl file, add the following:
-Didv.data.geosubset.bbox=latul,lonul,latlr,lonlr where: latul - upper left latitude lonul = upper left longitude latlr - lower right latitude lonlr = lower right longitude for example: runIDV -Didv.data.geosubset.bbox=40,-113,20,-95 foo.islThat sets the default bounding box for all data sources in that invocation. In theory, that should work. ;-) Let me know if it doesn't.
