Background Information for Students

Background for GeoTools Community

Sample Idea to cut and Paste


h3. Lite Swing Example

GeoTools used to have a StyledMapPane viewer that a lot of people used as an
example when creating their own Applications (and Applets - remember GeoTools
is old). This example was dropped after years of neglect (it was not updated
to an OGC compliant CoordinateReferenceSystem implementation if you must know).

Can you *please* over the course of the summer make us a new "lite" example.
We are excited by the idea of the Spring RCP framework (so you could test your
component there), but the example should be "lite" enough to work as an applet.






JMagick integration.

JMagickis an open source Java interface ofImageMagick. It is implemented in the form of Java Native Interface (JNI) into the ImageMagick API. Jmagick has proven to be very fast and quite stable with jpeg and png files especially when compared to imageio plugins.

It would be great to try and hide JMagick behind imageio-ext (some work has already been done in this direction in order to later expose imageio-ext plugins as geotools plugins. 

MrSID and ECW plugins based on gvSIG JNI wrapper.

gvSIG has direct JNI wrapper for ECW and MrSID. Even if the license is not fully compatible with the geotools one it would be nice to provide a few imageio-ext plugins to expose this capabilities in geotools afterwards.

GCP Support in GeoTiff plugin.

It would be nice to add support for Ground Control Points in the GeoTools geotiff plugin. This would mean doing some refactor of the current plugin. We could also port the work performed last year by Jan during the SoC 2007 on warping into geotools trunk.

BigTiff support.

Actually SUN's ImageI/O doesn't provides support for BigTIFF format. Tiff files size is limited to 4GB (Having file offset encoded as a 32 bit values).
BigTIFF format allows to handle larger files. It would be great to extend ImageIO capabilities by adding suppor to BigTIFF.
Further details on BigTIFF are available at BigTIFF file format proposal page.

WCS Client library

It would very useful for the users to have a GeoTools client library for WCS similar to the ones for WMS and WFS. They could retrieve raster sub-datasets for processing or visualization on GeoTools based clients.

Emergency Response or MIL2525B Symbols

There are additional "well known" symbols besides those mentioned in the Style Layer Descriptor specification, it would be very valuable to make the Emergency Response and MIL2525B symbol sets available to the community.

Here is an RnD page: Custom Symbols for MIL2525B and EmergencyResponse

H2 spatial indexing

Currently we have a data store implementation based on H2. To be a true format for handling large amounts of data a spatial index is needed. H2 itself does not have a built-in R-tree index. Therefore a alternative method of spatial indexing is required. A proposed solution is to use the approach taken by arcsde in which indexes are built with auxiliary tables. This project involves exploring and implementing that type of index in H2.

Geo-spatial analysis with R

R is an open-source, multiplatform language and environment for statistics. It consists of a core application together with a huge number of available packages, each of which provides additional analytical capabilities. R has become widely used for geo-statistics (see here for a summary).

A very interesting and useful SoC project would be to explore ways in which GeoTools could work with R: exchanging data, running analyses and visualizing results. This work would be at proof-of-concept level.

Analytical coverage

An analytical coverage can be thought of as ...a spatially bounded set of direct positions, and a mathematical function that relates direct position to feature attribute value (quoted from here).

This SoC project would explore how analytical coverages could be implemented in GeoTools. One possible starting point is Jiffle, a scripting language for raster data (images, grid coverages) which might provide the basis for a spatially-aware, expression evaluator working in continuous space.
