My understanding of Ibycus topo is limited. I apologize if I'm getting this substantially wrong. In my opinion the answer to your question is this: Ibycus and OpenStreetMap are two different projects with different goals. What's wrong with Ibycus? 0. Ibycus is restricted by the non-commercial clause of the cGPSmapper compiler. cGPSmapper is also proprietary. This limits my interest in cGPSmapper and in Ibycus. 1. Is the entire Ibycus download in Garmin format? Isn't the Garmin format a proprietary format that is (imperfectly?) reverse engineered? Reliance on a proprietary data format is a very bad idea. Why would we restrict OpenStreetMap with data in a proprietary format? 2. Ibycus is described as "topo maps for Garmin GPS." Wouldn't that turn the Canadian portion of OpenStreetMap into just a topo map for a Garmin? That makes OSM Canada less useful than the rest of the World. 3. Ibycus is not the data source. Any conversion from original to Ibycus to OpenStreetMap is dependent on the Ibycus step. OpenStreetMap can go directly to the data sources without relying on Ibycus. What's good about Ibycus? Ibycus is good enough for Sam to be a fan. That suggests to me that Ibycus is good at the intended purpose, it is a good topo map for Garmins. Congratulations Dale, on creating Ibycus, and thanks for hosting the large downloads. What next? Other projects have been included in OpenStreetMap after demonstration as a separate project. For example, the cyclemap is now included as a layer on OpenStreetMap. It was a separate map, using OSM tools, plus tools modified and or created for the cyclemap. Many people enjoyed it and asked that it be included in OpenStreetMap. Not everything can be included in OpenStreetMap. For example, an added layer requires additional layer rendering. Serving additional layer tiles consumes more bandwidth. The additional resources of tile server bandwidth and rendering servers reduces the resources available for the rest of OpenStreetMap unless a sponsor can provide the resources to the new project. Conclusion The goals of Ibycus and OpenStreetMap differ in ways that make importing the Ibycus data to OpenStreetMap undesirable in my opinion. Ibycus enthusiasts can use the open and Free OpenStreetMap tools to demonstrate the utility of Ibycus to build support for including Ibycus in OpenStreetMap in future.
