Hi all, I've created a national county, MSA, and state map of the United States. It's at: http://www.margieroswell.com/svg/nation.htm
It has some drawbacks: - It's large and therefore sluggish. (Zipped svgz file is 2 mb. The original FCC MapInfo file was not very generalized.) - Also, this doesn't do much. In fact, it does little but default viewer behavior That's where you come in! (well, if you want to.) (Actually, apart from default behavior, there is some nice javascript for turning on and off layers that seems to work well. Another feature is that the IDs match the state and county FIPS codes) What else can we do with this (if anything)? First of all, looks like I need to find tools to generalize boundaries (or maybe it's easier just to purchase pre-generalized county maps?) I want to eventually be able to do choropleth mapping, and variable sized pie charts. Here are some good county-level data sources, in case you want to work at that level: http://www.census.gov/popest/datasets.html http://www.ssi.nrcs.usda.gov/CustomData/DataCounty.html http://fisher.lib.virginia.edu/collections/stats/crime/ (That's "Uniform Crime Reports County Data") I do promise to release a state file (subset of this--just the state layer) so that screen redraw isn't a problem, over the weekend. When that's up (it's not yet) it'lll be at: http://www.margieroswell.com/svg/states.htm The Holy Grail (great sample SVG map applications): http://www.carto.net/neumann/cartography/vienna/ http://www.carto.net/papers/svg/us_population/index.html http://www.statistics.gov.uk/about/methodology_by_theme/area_classification/la/svg/index.html http://www.InstantAtlas.com/ I'm aiming to climb the learning curve, and welcome others joining in the merriment, at whatever level. If anybody comes up with something interesting from this, carto.net has mentioned an interest in hosting innovative solutions and basic tutorials...Carto.net is truly an awesome resource. On the homepage front, I should add that my margieroswell.com site is, alas, hopelessly out of date (well... a year old) ..Will maintain as time permits. Have to dig up some old MySQL password, I think. I welcome participation by others in learning and sharing information on building GIS-style SVG apps. Drop me a line if this sort of mapping interests you... Let's see if we can figure it out together, and maybe "give back" to carto.net, too, as we develop our skills.
