Paul, To verify your data you could also use the Province of BC's WMS Services. Here are two that you may find useful for the UBC Area.

UBC, Vancouver orthography, and street alignment (Paul Norman) ---------------------------------------------------------------------- Message: 1 Date: Sat, 30 Oct 2010 21:18:03 -0700 From: "Paul Norman" <[email protected]> To: <[email protected]> Subject: [Talk-ca] UBC, Vancouver orthography, and street alignment Message-ID: <[email protected]> Content-Type: text/plain; charset="us-ascii" UBC in Vancouver has been suffering from issues of building misalignment because the Yahoo orthography is misaligned with the ground and suffers from distortion[1]. The City of Vancouver offers some mapping data [2] which can be used with OSM. I've taken 16 tiles that cover most of UBC and corrected most of the streets to these as these reflect the GPS traces, CanVec data, and my knowledge from being a student. They are also high resolution, being listed as 40cm, but I can easily make out smaller features. I've also done some micro-mapping around the SUB, Buchanan, the Chan Center and Rose garden, and down by CEME. As the process to convert the .ecw files is a long and computationally heavy one if anyone wants the resulting slippymap which can be used with the JOSM slippymap plugin and is regularly at UBC I could burn them onto a CD. I also have all of Vancouver processing to make a slippymap, but it has only been about 25 hours so it is not finished yet. If anyone wants that, it'll take multiple DVDs. Of course, anyone could recreate it from the downloaded files but anticipate gdal2tiles taking about 30-40 hours on a good computer. If anyone notices misaligned streets at UBC and isn't able to get the Vancouver orthography working I'd appreciate knowing and I can align them.
