java gis library [closed]

Question

What is the best/user friendly GIS/arcGIS Java library for basic academic assignment?

Answer 1

I haven't used it myself - but you might start by taking a look at GeoTools:

Sample app tutorial: http://www.ibm.com/developerworks/opensource/library/os-kmlservice/index.html?ca=drs-

Answer 2

Java Topology Suite is a good option for 2D spatial operations. http://www.vividsolutions.com/jts/jtshome.htm

Answer 3

Esri released our Java Geometry engine under the open-source apache license.

https://github.com/Esri/geometry-api-java

It should cover most, if not all, of the geometry operations that you need.
