	The objective would be to integrate the Aparapi library in gvSIG, so it might be used in the development of new parallel geoprocessing algorithms which take advantage of current GPUs. Also some geoprocesses would have to be developed or converted to use the Aparapi library to check the benefits and the proper operation of the idea.

−	~~'''1. Introduction'''~~
−
−	gvSIG Scripting Framework is a small environment for development and execution of scripts that interact with the application.These scripts allow us to automate small tasks or add some functionality that we need and that we can implement. This feature helps the developers to test their implementations locally with much less effort.
−
−	~~'''2. Background'''~~
−
−	At this moment, using Scripting Framework one can load raster layer and perform some filtering operations. This was implemented as part of GSoC 2013 idea [https://google-melange.appspot.com/gsoc/project/google/gsoc2013/kumarsandeep2357/6526151266664448 Add Raster Format to Scripting in gvSIG]
−
−	~~'''3. Idea'''~~
−
−	This idea concentrates on extending the capabilities of Jython Scripting in gvSIG Desktop. A lot of Raster functions like histogram analysis, flow direction analysis, geoprocessing etc., which stand as a major advantage of using Raster data should be implemented in Scripting Framework.
−
−	Filtering of raster images is one of the key feature of image analysis. As of now, the filtering operations consume lots of time even on small images. This can be optimized by making use of the already implemented gvSIG kernels from Java.
−
−	As of now, one can load .tiff files using Scripting Framework. This should be extended such that one can load .ecw, .jp2 files. Loading a layer in a tiled way, loading WMS and WCS layers, getting the ROI of a layer as a vector layer etc., should be implemented.

-The idea is about adding to gvSIG Desktop 2.x a new data provider for reading XLS files (Microsoft Excel spreadsheets). Taking into account that the latests versions of Microsoft Excel don't support DBF file format (the most common table format used in gvSIG) this feature would facilitate the data transfer from MS Excel to gvSIG.
+The management of alphanumeric information contained in tables is a critical question of spatial analysis, but often the desktop GIS applications are not as powerful as a spreadsheet application for this kind of tasks, so having the possibility of transfering data between both types of applications would be very useful.

OGR offers us the perfect platform to implement demanding format transformations and the corresponding file format outputs as many desktop GIS application already do.

		+	At this moment, gvSIG gets access to a reduced list of file formats and transformations.
		+
		+	'''3. The idea'''
		+
		+	The main idea behind this project is about integrating the OGR library into gvSIG Mini. The OGR library provides several capabilities for simple features vector data; however it should be mentioned that OGR is also part of the GDAL source tree, so that by integrating OGR we do integrate GDAL as well, getting access to GDAL raster capabilities(for future developments). This proposal improves the application interoperability, and in general terms, the supported range of geoprocesses and transformations.
		+
		+	Once the solution is adapted and compiled, we would proceed to adapt and connect the full OGR data model with the data model gvSIG works with and provide full support to the SHP format. The implementation is intended to be done in a way future formats supports are easily developed.
