Thank you for the usable, non-pdf link.
Something I learned yesterday: Apparently La Guardia has a midnight curfew, meaning that any planes that need to land after midnight get rerouted to JFK. Although this curfew often gets extended due to weather, it's still something worth keeping in mind when booking return flights into LGA that get in after 10pm in general.
Really a pdf...government.
A simple jpeg would of worked.
Not really. This file is 1.5MB, and a 150dpi low-quality JPEG export of that is 2.7MB and the street names are barely legible. For a map like this, consisting of mostly text and really simple vector data, with only a handful of colors, raster images are really inefficient.
Would svg be better? I mean, lighter and legible.
Not likely. A quick test of several compression formats shows that this file can only be shrunk by about 20KB, so it's already had most of the redundancy removed. Re-encoding the same information as SVG isn't going to make it more compact. What would make for a more compact download would be removing detail: the coastlines could be simplified, and perhaps not all the roads need to be shown. That would also speed up client-side rendering time, which is the biggest downside compared to raster images.
Does anyone know anything similar for Jersey City?
Voluntary evacuation for downtown. http://www.jerseycityindependent.com/2011/08/26/jersey-city-...
