Hi all, I was doing some cleaning up and some building mapping in the Makati CBD area and I noticed that the satellite imagery in Yahoo! (provided by GeoEye) has some really bad stitching (multiple satellite imagery were stitched into one "seamless" mosaic). One particularly bad example is that Rufino St. (Herrera) is broken along Ayala Avenue. The stitching of the imagery seems to be along Ayala Avenue and Buendia. If you'll check out the parts of Buendia near the RCBC Plaza, you'll notice that there are two shadow images of Buendia there.
I think this means that the data in the Makati CBD area might be quite off in some parts. I think that we need to supplement this with some really good GPS traces (the existing uploaded GPS traces are quite noisy) but the problem is the urban canyon effect that makes GPS a bit ineffective in this area. What do you guys think? Eugene / seav -- http://vaes9.codedgraphic.com
