GeoTools 2.2.M2 Released

Geotools开发小组宣布Geotools 2.2.M2 发布。

GeoTools是比较成熟的开源GIS中间件，有近10年的历史，并且还有一定的OpenGIS官方背景，是英国Leeds大学提供的地理java基础类和源代码。

可从www.geotools.org下载源代码。

geotools采用java实现，架构非常优秀，容易扩展。geotools中采用了另一个著名的开源软件JTS（java拓扑套件）。JTS封装了常用的geo算法，并且实现了OpenGIS的简单特征规范，也提供了基于内存的空间索引

新版本添加了PENN UNIVERSITY的ColorBrewer项目。
the offical site said:
This release contains an improved API for aggregate functions (min, max, average, etc…), and contains optimized implementations for most SQL based datastores. We are pleased to included ColorBrewer from Penn State University. Also we have a a couple of exciting house keeping changes. How exciting? Main has been split into four: Referencing (for implementations of GeoAPI), api (for all the stable interfaces), coverage (to help those working on ISO compliant raster support) and finally main (returning for a repeat engagement of our default implementations). This release in made in conjunction with uDig 1.1.M0.
