#2290 closed enhancement (fixed)

[raster] ST_ColorMap

Reported by: Bborie Park Owned by: Bborie Park
Priority: medium Milestone: PostGIS 2.1.0
Component: raster Version: master
Keywords: history Cc:


Apply a user-specified colormap to a user-specified band (defaulting to 1).

  rast raster, nband int,
  colormap text,
  method text

The color map is specified in the same format as that for gdaldem's color-relief. Some predefined color maps can also be specified by keywords (probably after the explicit mechanism works well).

cool any chance we can have this for 2.1?

comment:2 by Bborie Park, 11 years ago

Probably… I'll try to get it done for 2.1.

That'll be great. I've switched to 2.1 and we can always switch back if you can't get to it by then.

This is super neat. Now I don't have to create all these stupid bands to output my images in png bright color anymore and will be great for my geometry map charts.

I put in an example at r11394 . I still need to put in an example of a custom colormap.

Okay I added an example of a custom color map at r11398
