Take the 2-minute tour ×  Does anyone know of any examples of
web-apps that allow user-input to change variable weights used
to calculate symbology?  My organization is looking to build a
dynamic mapping application and while I have the tech-savvy to
envision and outline the project, I don't have the coding
experience to implement it myself (I've been working with GIS
for close to 10 years, but I am new to development). I have
access to both GeoServer and ArcGIS Server, and I'd appreciate
any input on how to go about this task (FLEX vs REST vs JS vs
MYSQL vs POSTGIS vs GeoServer vs ArcGIS, etc)  We are creating a
series of opportunity maps based on neighborhood indicators.
Essentially, we compile a set of data at the census-tract level
for an MSA and convert the variables to Z-scores. Then we
aggregate Z-scores to create a composite index for a certain

into 6 quantiles and shade them accordingly. For example:
