• Purpose– Display listings on map– Display surrounding information ( schools, parks,
etc …)
Mapping

Current Metrolist Mapping
• ESRI– Provides Metrolist with a map server– ESRI provides a way to put layers on the
maps ( roads, parks, etc … )– Static images and dynamic maps

Current Metrolist Mapping
• Current maps for listings are static1.Calculate coordinates2.Get map as image3.Listings show up as part of image
• Metrolist’s dynamic map– The dynamic map allows full navigation– The dynamic map doesn’t show listings on it

• Problems with current approach– Static maps don’t provide much information
about surrounding region– Hard to tell precise location– Multiple listings on a single map make it hard
to distinguish between listings
Current Metrolist Mapping

Future Metrolist Mapping• Dynamic maps with dynamic content
– Navigation – zoom in/out, scrolling– Listing information available on the map– Polygon selection and search integration

Detailed Mapping• Mapping DHTML
– Dynamic navigation using JavaScript (on click coordinate recalculations)
– IMG tag changes src element to get the correct image
– Markers are loaded with information and info is hidden from view

• Polygon Selection– Concave polygons– Graphics library - wz_jsgraphics by Walter
Zorn– Line drawing and Vector collision detection
• Can’t intersect– Unlimited number of points– Client vs. Server

Challenges
• Compatibility issues– DHTML and browser compatibility– Current mapping browser support
• Speed– Client bottlenecks– Server bottlenecks– Transfer bottlenecks

Future Features
• Dynamic loading of large image blocks for instantaneous scrolling.

Future features
• Integrated search engine– The Metrolist search engine will be integrated
with the map.
