v1 v2 218 218 * polygonize with GDAL or GRASS, that generates some internal structure for those libraries, and you turn that into a WKT form of polygon. That can be passed to PostGIS, and you don't need to link to liblwgeom.[[BR]][[BR]] 219 219 1. Best practice for band referencing: having a band parameter (index?) or always use RT_Band()[[BR]][[BR]]-e.g. SELECT RT_AsTIFF(RT_Band(raster,2),60) FROM coverandtemp[[BR]][[BR]]SELECT RT_AsTIFF(RT_Band(raster,2),RT_Band(raster,1),60) FROM coverandtemp[[BR]]or[[BR]]SELECT RT_AsTIFF(raster,2,60) FROM coverandtemp[[BR]][[BR]]Pierre: Having a band parameter (or a list of band) for each function trying to access a band would be preferable to avoid useless memcopy of band data.[[BR]][[BR]] 220 1. Architecture & design issues: 221 220 1. Architecture & design issues:[[BR]][[BR]] 222 221 * How to handle no NODATA? Pierre from Frank input: We'll need a HasNoDataValue flag for each band.[[BR]][[BR]] 223 1. Documentation 224 225 * Setup a structure (likely on a Wiki), sections for developers and for users 226 227 * Update existing documents like RFCs - they are out of date. 228 222 1. Documentation[[BR]][[BR]] 223 * Setup a structure (likely on a Wiki), sections for developers and for users[[BR]][[BR]] 224 * Update existing documents like RFCs - they are out of date.[[BR]][[BR]] 229 225 * Describe key terms: canonical format, serialized format, transfer format (WKB), in-db raster, out-db raster, etc. This should help people to grasp the WKT Raster key elements quickly, and help them to decide which document/RFC to read in details.[[BR]][[BR]] 230 1. Development Roadmap 231 226 1. Development Roadmap[[BR]][[BR]] 232 227 * Review current schedule. 233 228 * Add note on a website where users should (or should not) expect 1 release - clear statement.
