I want to create a map of the USA that highlights the top 100 metro markets. I want four markets -- New York, Chicago, Washington and Seattle -- to be highlighted in one color and the other 96 markets to be highlighted in another color. This would be the source for the top 100 markets --http://en.wikipedia.org/wiki/List_of_Metropolitan_Statistical_Areas Any tips on how I can do this? Thanks for your help. |

Various methods are possible. You could use an OpenLayers or Leaflet map embedded in a web site (this will be zoomable and pannable) and save your 100 dots in a KML/GeoJSON file which you could create with any suitable editor (among others, Google Earth). Then instruct OpenLayers/Leaflet to display your file. There are platforms, e.g. Github, where you can simply drop in a GeoJSON file to have it shown as a map. If you'd rather have an image generated (and not some kind of web map), you'll probably not want to use OSM since it is a much too detailed data set - just create a KML file or Shape file or something with your markers in it, fire up a GIS editor like Quantum GIS, load a background GeoTIFF from somewhere, and put your dots on top. All these methods will require that you have coordinates for your dots, not just city or region names. If all you have is names, you need to run them through a geocoder first to get coordinates. Also, all methods will require some scripting and/or programming.
