I am happy too that he made it :) And may add what Christopher is planning to work on:
below you will find his proposal (excerpt): ******************************************* *JTIN v2: database backed, multi-resolution triangulated irregular network for Java GIS* *Describe your idea* Introduction: I plan on expanding my previous work on implementing a terrain model within OpenJUMP. Specifically, I want to work on triangulating, storing, and displaying large datasets. This will include work on integrating the H2 database as a native data format for OpenJUMP. Background: Last summer, I was fortunate enough to participate in the Google Summer of Code working on OpenJUMP under the OSGeo umbrella. I coded into OpenJUMP a basic terrain representation that included a binary file format, in-memory representation, triangulation from points, and display within OpenJUMP. While happy with the end result, I had envisioned a much broader idea for what surface modeling within GIS should entail. I would like to devote myself this summer to bringing JTIN closer to my vision. The idea: Expand JTIN to support extra large TINs by developing a stream oriented tringulator and storing the resulting TIN within a spatial database in a multi-resolution format. *Project plan (how do you plan to spend your summer?):* 1. Integrate H2 + spatial extensions into OpenJUMP as a native read/write format. 2. Add a TIN data format to H2 that would allow for storing a spatially indexed TIN that can be queried to extract arbitrary subsets at varying resolutions. 3. Expand OpenJUMP to use the caching ability of database backing to only load into memory the portions of the TIN it needs at the coarsest resolution acceptable. 4. Write a new stream oriented triangulation module that could triangulate DEMs that exceed system memory. Data would be streamed from disk, through a triangulator, then stored back to disk in an H2 database. Future ideas: Once the ability to deal with large datasets is settled, work should turn toward the user interface side. Examples include optional OpenGL accelerated 3D display, expanded TIN theme options, and new plug-ins that use the TIN data like hillshades, stream finding, watershed delineation, and future hydrographic modeling. ************ so you see he plans to work on something very important too - our in-memory problem :) congrats Christopher! stefan Sunburned Surveyor wrote: > Christopher DeMars was selected for an OSGeo Google Summer of Code > project.
