---+ Ducky's Info Vis Project [[http://www.cs.ubc.ca/~tmm/courses/cpsc533c-05-fall/projectdesc.html#proposals][Proposal specs]] -- my [[DuckyInfoVisProjectProposal][project proposal]] ---++ Current best idea: mashup Google Maps * darken all areas that are not within X meters of {grocery store, cafe, ATM, ...} * show different opacity/hue for different area levels * place little people (shape based on gender; color based on race) on a Gmap * have rollover that shows what districts a given point is in -- school district, US senate district, state rep district, city, water district, sanitation district, blah blah blah (man, that would be useful!) * simply showing the tiger census tracts is hard! ---+++ Resources * [[http://www.boutell.com/gd/manual2.0.33.html][GD library]] * [[http://www.google.com/apis/maps/documentation/][GMaps API]] * [[http://www.w3.org/TR/1998/NOTE-VML-19980513][VML]] (not sure exactly what use this is for -- maybe undocumented?) * [[http://forge.gridforum.org/projects/dfdl-wg/][Data Format Description Language (DFDL)]] * [[http://gis.ednet.ns.ca/gis_uses_in_US.htm][various GIS data, including e.g. place names]] * [[http://www.andysocial.com/wiki/index.php/Imagery_Programs][microdem]] * [[http://brainoff.com/geocoder/gmaps.user.js][simple JS to load points from a remote file]] * [[http://www.engadget.com/entry/1234000917034960/][annotated gmap howto]] ---+++ Tasks [[http://www.webfoot.com/gmaps/test.html][what I've got so far]] * Find good shapefiles * [[http://www.census.gov/geo/www/tiger/][TIGER database]] * [[http://www.census.gov/geo/www/tiger/tgrcd108/tgr108cd.html][more on TIGER]] * [[http://www.census.gov/geo/www/tiger/tgrcd108/tgr108cd.pdf][TIGER/Line format doc]] * [[http://www.flsenate.gov/senateredistricting/freds_data.cfm][Florida shapefiles]] * [[http://proximityone.com/tractscv.htm][Tutorial for Community Viewer]] * [[http://proximityone.com/tlfgeocoder.htm][Prox geocoder]] * [[http://www.esri.com/data/download/census2000_tigerline/description.html][ESRI Tiger shapefiles]] * [[http://shapelib.maptools.org/][Shapefile C library]] * [[http://shapelib.maptools.org/shp_api.html][.shp API]] * [[http://shapelib.maptools.org/shapelib-tools.html][shapelib utilities]] * Figure out algorithm for determining what tracts are visible on any given map * Figure out algorithm for drawing tracts on gmap * Figure out algorithm for how to resize overlays on zoom (need to remove and replace?) * Find candidates for area data * http://graphics.stanford.edu/~klingner/online_databases.html * [[http://countingcalifornia.cdlib.org/][Counting California]] * census -- too much data? * services: grocery, restaurants, bookstore, bank, bus stop, etc -- scrape Yahoo YP? * Calif STAR scores -- how get data on school district boundaries? * EPA data -- too much? * Select area data * Figure out how to create PNG * Try out GD library (<nop>ImageMagick as backup) * <strike>Figure out how to overlay one png on static map</strike> * <strike>Figure out how to overlay another png when map is recentered</strike> * Decide how/figure out how to convert data into PNG * Code to convert data into PNG * Code to overlay images * Code to pass scrolling information from overlay to map (so can "drag" map even with an overlay on top * (aggressive) sliders to allow changing the parameters of the * (aggressive) checkboxes to allow combining data sets * (extremely aggressive) allow semi arbitrary data to be mapped * design with XML format * design interactive * <strike>find information about Mike Beckerle's data description language</strike> ---++ Scratch * So far I know: * lines are easy * points are easy * icons are easy * shaded shapes: maybe with VML? maybe with one honkin' big icon? * mucking with the image directly is hard (given constraints of licensing, speed) * geocoding is hard * getting local services info is hard? * Yahoo also has API * MS also has API -- less functional and less well-documented tha Google API
