+Implementation in version:
+
+== Summary ==
+
+It is proposed that a set of functions or methods for raster band object are written to support "raster algebra", i.e., a set of operations, which modify bands or compute values from bands. An example of a modification is adding a value to all the cells of the band. An example of a computation is the maximum cell value in the band. Operations may or may not arguments, in addition to the band itself, and if they take, then the argument may be a numeric value, a complex data structure, or another band. Similarly, the computed value may be a simple numeric value, a complex data structure, or another band.
+
+== Rationale ==
+
+Raster algebra is a well known branch of geospatial science and technology and an often needed tool. Currently GDAL does not have comprehensive support for raster algebra in core.
+
+== Changes ==
+
+The RFC can be implemented as methods in the !RasterBand class or as a set of C callable functions. This needs to be decided.
+
+== Drivers ==
+
+Drivers are not affected.
+
+== Bindings ==
+
+The functionality will be added to the bindings.
+
+== Utilities ==
+
+A new utility will be written to take advantage of the functionality.
+
+== Documentation ==
+
+Will be written.
+
+== Test Suite ==
+
+Will be written.
+
+== Compatibility Issues ==
+
+== Related tickets ==
+
+== Implementation ==
+
+The implementation will be done by Ari Jolma.
+
+The proposed implementation will be in https://github.com/ajolma/gdal
