Michael's reply to you about the "trivial transformation guideline" of 30 October agrees with this - in his terms it provides no new "physical observations" and the intent of the license is to capture those for share-alike, not to extend share-alike to any technique used for storing or transmitting the data.<br>

What are the other examples you had in mind? Real-world examples are exactly what we need for this.</blockquote><div><br></div><div>Some more:</div><div><ul><li>Various forms of algorithm-driven generalizations: simplifications of roads and polygons, merging of polygons with same or similar landuse, elimination of polygons that are too small for given map scale (like buildings), amalgamation...<br>
