latitude and longitude quirk

Support - Assistance technique
#1

Never noticed this before ... when we serialize the coordinates of a
point like this [30.02538,-2.18537] we interpret this as <long>,<lat>.
This seems odd. I think the convention is <lat>,<long>

#2

I think this is the default on GML 2.1, WKT and WKB formats, so this
probably explains it. ogr2ogr will by default export long/lat instead
of lat/long.

And geojson also, which is what we are using this for.

In conventional math the order is (x, y, z) and most GIS tools and frameworks use the same order, afaik. Including geojson/openlayers.

How to avoid java.lang.OutOfMemoryError: PermGen space

I run Tomcat 7,

Java version:
1.7.0_05
Java vendor:
Oracle Corporation

You can set JAVA_OPTS environment variable to something like:

-Xmx512m -Xms256m -XX:PermSize=128m -XX:MaxPermSize=128m

-XX:NewSize=128m

these values may increase/decrease depending on your available RAM.
