Work Completed

  • Created new image of MAEviz field mapping. The old image used fields that already matched which could be confusing to a user. This new image replaced the old one on the MAEviz wiki.
  • Meeting with Jong to discuss Market Maker and how we should proceed.
  • Worked on Market Maker issue with loading WFS feature layer in OpenLayer canvas MM-23. The problem was that we were making XMLHttpRequests which are not allowed if the domains do not match. The fix required us running a proxy that MarketMaker provided so the request could be motified to match domains. After doing this, we successfully loaded features from our geoserver onto an openlayers canvas.
  • Worked on MarketMaker issue MM-25. When loading WFS data from our Geoserver, we need to be careful with the amount of XML transmitted because a large number of features could cause the browser to crash. OpenLayers has a feature for displaying layers by zoom level so using this, we display census tracts as an image (from WMS) until the user zooms in to a small enough area and then we switch over to displaying the census using features (from WFS). I will look into this issue further to see if we can determine display based on the number of features that would be visible in the bounding box.

Work Planned
