Hello DSpatial developers, Version 0.3.1 of the DSpatial kernel was released on Sourceforge today. This is a maintenance release with no new features, but a truckload of bug fixes. Most of these bugs came to light during the development of release 0.1.2 of the gridmath module, also newly available today. The new gridmath module release 0.1.2 contains a new unit that implements a fairly extensive array of mathematical functions that operate on a single raster band. These functions include simple arithmetic, trigonometry, power and logarithms, and a few support functions. With this module it is now for the first time possible to manipulate raster data with DSpatial! Attention is now shifting back to the kernel where a so-called filtered data access object is being developed. This filter maintains a defined region of a raster band and it supports notions such as current pixel and relative pixel addressing. This filter access will greatly reduce the complexity of analysis functions that operate on multiple raster bands, or local functions on a single raster band such as those to be included in the terra and orbit modules. Documentation of DSpatial and the gridmath module are still sorely lacking. Especially needed right now are detailed documents on programming with the DSpatial kernel and the extension modules, and on how to develop additional raster drivers. A volunteer who could take this task on would be greatly appreciated. A DSpatial news group has just been added on news.gmane.org. The news group gmane.comp.gis.dspatial.devel is a news mirror of the mailing list on SourceForge. The news group has been added to lower the effort to discuss DSpatial issues, using your news reader of choice. More news groups will be added on GMane when the need arises. Thanks, DSpatial development team |
