# Spatial Opimization ZillionInfo Online supports spatial optimization on points (site selection), lines (routing), and polygons (redistricting). **Redistricting** Redistricting divides an area to a number of districts that meet multiple goals and satisfy multiple constraints. For example, political redistricting requires to produce districts that balance population, keep compact boundaries, minimize crossing of administrative boundaries, satisfy COIs, etc. School redistricting requires to produce districts that balance student enrollment and school capacities, have compact boundaries, minimize the distance to schools, etc. iRedistrict Online: Please contact to subscribe to iRedistrict Online. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
