Hey I've had an entertaining morning going through pretty much all of the posts to this forum, and many of my initial questions are answered already (OSM newbie here). I do have a question or two which i am hoping someone here can help me answer.
I'm busy building an application that is looking to leverage OSM data (commercial application, distributed with some hardware, not open source). In order to distribute that application in an offline environment, and not sit with 100Gigs worth of files, I understandably have to filter out everything the end user won't need, and try store the data in a format that is highly optimized. Background facts: I am not going to change any underlying OSM data... everything will come from the planet file and the subsequent diff files. I would just filter out things that are not absolutely required (so basically keep street level data). I am looking to store the data in a custom (potentially binary based) format to try save space, so I will change the way it is stored... the OSM XML is really bloated for what we need. Here are the questions: 1. Would I be allowed to leave out the "user" and "timestamp" tags in the version that I create? Could I leave out any unnecessary tags (there are a few)? These tags just create extra data storage requirements and really don't help the situation (I want to filter down to the size of a single DVD if possible). The way we want to store the data, it's not likely that users would be able to access it in any case. 2. Do I need to make this data available in any other way other than on the DVD that we distribute with the software? There's no added benefit that I see for others, as it's just a cut down version of the OSM database (other people loose out on data). There is a concern that we would have to incur a substantial cost if we were to make this freely available over the internet as we are operating in a costly bandwidth environment. This may not be possible. We may also change the format with software updates, and don't really want to have to publish our format, get other people hooked on it.. then get restricted in our efforts to change it at whim. We would obviously attribute the map data source to Open Street Map... or the users... or whatever make sense (suggestions?). Thanks for any replies.
