<div dir="ltr"><div><div><div><div><div>Mike,<br><br></div>Firstly, I think Tom Chance has covered all the significant issues.<br><br></div>I'm assuming that the types of assets your potential users are interested in are of the order of schools, libraries, health facilities etc. rather than street furniture. In these categories I would estimate a typical level of coverage in OSM will be between 30-50%. With open data there is scope to improve coverage in many of these areas. However such POIs are likely to be mapped in diverse ways: from a single point for a school to a polygon for the school grounds with buildings, staff parking, playgrounds and playing fields all mapped, In initially presenting information it will probably best to abstract things to a single representation (e.g., polygon centroids). A related problem is of duplication: a school polygon with a separate node containing the school name. Again some kind of pre-processing of the data for specific assets may be useful.<br>
<br></div>The potential complexity of the underlying representation may create problems. Tom has covered this in his point 2.<br><br></div>Regards,<br><br></div>Jerry Clough<br></div><div class="gmail_extra"><br><br><div class="gmail_quote">
