Houston Hybrid

July 23rd, 2005
 

The whole Internet seemed to be abuzz today with news of the latest Google Maps innovation: a hybrid map that combines map graphics with satellite photos (the detailed photos of urban areas are not satellite photos, but aerial photos taken from airplanes). I really like the hybrid views, but I think the image generation heuristics need some fine tuning: look at how many times I-610, the "loop", around Houston is labeled in this hybrid map:

If I-610 is over-labeled, then I-45 and I-10 are under-labeled. I-45 is coincident with US Highway 75, but the road is repeatedly labeled 75, and is only once labeled I-45. I-10, the major east-west highway through Houston, is coincident with US 90 and State Highway 53, but it not once labeled I-10. Most maps give precedence to the Interstate designations over the US and state highways designations. Google has apparently decided to do things the other way around.

    Hehe, I was playing with Google Earth yesterday, and zooming in to my local area, noticed they’d completely obliterated I-5 in WA state, opting instead to label the more minor highways that ran alongside it or combine with it here and there. Made me snerkle. It takes so little to amuse me, I guess.
