     62'''What did you get done this week?'''
     63 * Read Documents and [http://www.cef-cfr.ca/index.php?n=Membres.PierreRacine Pierre Racine]'s [http://www.cef-cfr.ca/index.php?n=Membres.PierreRacine#documents presentations] on PostGIS Raster; Learned more about the raster data storage and manipulation in PostGIS
     64 * Read [http://www.oracle.com/pls/db111/portal.portal_db?frame=&selected=7 Oracle Spatial Documents] on [http://docs.oracle.com/cd/E14072_01/appdev.112/e11827/toc.htm GeoRaster]; Learned about raster data storage in Oracle.

     67''' What do you plan on doing next week?'''
     68 * Learn more about PostGIS Raster development
     69 * Write a comparison of raster data storage and manipulation in PostgreSQL and Oracle
     70 * Write a proposal on how to adopt the concepts and algorithms of distance calculation in PostGIS.
     71
     72'''Are you blocked on anything?'''
     73 * It seems that Oracle Sptial dosenot provide distance analysis [http://docs.oracle.com/cd/B28359_01/appdev.111/b28398/geor_operations.htm#CIHIICDF functions for GeoRaster] data. '''Please let me know if I missed it.'''[[BR]]However, by reading documents of !GeoRaster, I got a better understanding of the raster data storage in spatial database. So I feel it would be helpful to write an analysis to compare the concepts of raster data storage and manipulation with PostGIS Raster and Oracle Spatial !GeoRaster.
