DESCRIPTION:The Mapping Service at the Center for Urban Research at the Cit
 y University of New York (CUNY) Graduate Center engages with foundations\,
  government agencies\, businesses\, nonprofits\, and academics to use spat
 ial information and analysis to develop research projects. Our most recent
  set of web maps focus on the decennial redistricting process in the Unite
 d States. Redistricting is often a complex and complicated process. Delays
  in publishing data from the 2020 Census due to COVID-19 shortened the tim
 e frame for redrawing legislative lines in many states. Given the often ru
 shed nature of redistricting it was crucial to provide fair district advoc
 ates\, journalists\, and lawmakers with accurate maps and data shortly aft
 er the proposed districts became publicly available. \n\nIn previous proje
 cts\, we relied on proprietary back-end stacks using ArcGIS\, Microsoft SQ
 L\, and the .NET framework. These products afforded a viable but inflexibl
 e solution to our GIS needs. The online mapping platform for ArcGIS is not
  as elegant as its open source counterparts\, Microsoft SQL did not provid
 e a solution for directly serving vector tiles\, and each upgrade of Windo
 ws\, IIS\, and Visual Studio presented unique challenges. \n\nLast year we
  implemented a new back-end stack to connect our spatial databases to our 
 web sites using FOSS solutions: QGIS\, PostGres with PostGIS\, Mapbox\, an
 d Nodejs. The result is a free\, fully customizable solution that is easy 
 to update\, maintain\, and migrate. We are currently using it in about a d
 ozen applications to serve vector tiles and query demographic and other da
 ta. With our new workflow we were able to quickly upload dozens of map pro
 posals\, calculate metrics to analyze the potential impacts of each one\, 
 and present them on our website within hours of the data being made availa
 ble to us.
