Thinking in GIS

birt is a powerful Open Source Business Intelligence and Reporting Tools I came to use in the last weeks for a project. Its key features are:Eclipse based report solutionVery nice report designer producing a standard file. This file can be then used to deploy the report in several waysruntime component for easily serving reports on a server, also by a web server (like Tomcat)outstanding Java APIs for creating and modifying the report design (DE API), for consuming and deploying the reports in several ways (RE API) and for creating and rendering charts (CE API)For creating a BIRT report...

Here I post a sample Java class I developed some months ago, working with geometry creation in GeoTools 2. This class, given an input Shapefile, will elaborate an output shapefile merging the input polygons on a common field.Geotools is an open source (LGPL) Java code library which provides standards compliant methods for the manipulation of geospatial data, for example to implement Geographic Information Systems (GIS). The Geotools library implements Open Geospatial Consortium (OGC) specifications as they are developed, in close collaboration with the GeoAPI and GeoWidgets projects. The capabilities of Geotools are presented in the feature list./* * Created on...
