Projects / GeoTools


GeoTools is a GIS toolkit that is used for OGC-based projects via GeoAPI interfaces. It includes two great SLD based renderers and tools for raster access and reprojection as well as plugins for Shapefile, ArcGrid, ArcSDE, Postgis, OracleSpatial, MySQL, and many more.

    Release Notes: This release brings structured grid coverage readers to allow raster data sources that publish composite data products. Efficient support for multiple coverages in GridCoverageReader provides ad-hoc access to raster formats that publish more that one data product. The transform module has graduated to supported status, providing a seamless way to rename, retype, and hide SimpleFeatureSource attributes, as well as create new ones based on OGC Expression. Additional OGC modules for the WCS 2.0 and WCS 2.0 EO models, as well as the addition of XML parsers and encoders.

      Release Notes: This release fixed problems where joining more than two tables resulted in mismatching attributes, virtual table metadata did not work for column aliases, additional headers needed correction, and the GeoJSON module could not parse geojson objects with null geometries. It also added support for graphics-margin vendor options for graphic fills, removed proprietary com.sun package classes, and upgraded jaitools to 1.3.1.

      •  23 Jan 2013 13:18

        Release Notes: This release features several fixes in the WFS client, making it work against TinyOWS and the ArcGIS WFS server, and improvements in the usage of filter fuctions from SLD (some functions did not properly convert their arguments from string to numeric). Some tiling artifacts when rendering oversampled grid coverages were removed. FIDFilter objects in map rendering are now faster.

          Release Notes: This is a bugfix release made in conjunction with uDig 1.2-RC3. It adds support for Oracle Georaster access and many small but interesting improvements, including interpolate functions which are very useful when styling maps. Generated SLD files no longer write out "default" values, which will make for a more readable result.

          •  10 Dec 2008 21:13

            Release Notes: This release fixes an encoding problem from the shapefile attribute reader. WFSDataStore no longer hangs indefinitely on a connection. Inconsistent behavior in org.geotools.styling.StrokeImpl has been fixed. The 1.0 filter properly encodes FeatureId elements. A bug in the equalInterval function for non-numerical attributes has been fixed. CQL datetime values no longer throw an exception in Oracle. The encoder closes feature collections. A BBox filter with an empty property name should be supported.

            Wonderful API for GIS Apps. using Applet
            Thanx to James and his team for their continous effort and dedication which has resulted into a wonderful Java API for GIS Apps.

            I personally found the API very structured and featured which has been giving me constant thrill as I am exploring and learning the possibility.

            At somepoint sometimes it is difficult to clearly intrepret the meaning but with little code it becomes a see-thru-crsytal.

            I am glad to hit this site accidently. Thanx to google.

            Cheers Guys
