[SoC] GSOC weekly report 2 : Spatial clustering in PostGIS and CartoDB

[mohit kumar]

HI all,

*What I got done this week?*
Implemented the Sp-gist algorithm on a small postgres database.
The code was taken form the spgist homepage
<https://www.cs.purdue.edu/spgist/> and needs to be modified as per our
needs of cartoDB.
The code is not modified yet and so not updated on the repository due to
copyright issues.
Will modify the code this week and will update the repository

*What do I plan on doing next week?*

Modify the code for sp-gist to inculcate another integer field for various
levels of clustering based on zoom levels.

*Am I blocked on anything?*

I had some issues with the Sp-gist indexing implementation, but were sorted
out in discussions with sp-gist developers.

This report is also updated on the project page
<https://github.com/CartoDB/cartodb/wiki/GSOC2014-:-%22Fuzzy-visualization-on-low-zoom-levels-in-CartoDB-using-Sp-GiST-indexing%22>
.
