How the Interactive Map Generator Works
Traditional GIS software requires complex desktop tools, heavy shapefiles, and specialized database training. SparkMap brings advanced map generation directly into your browser.
Select any of six curated data lenses—including Income Mobility, Child Opportunity Index, School Quality, Health Infrastructure, Economic Security, and Incarceration Risk. Adjust percentile thresholds to isolate specific neighborhoods across MCPS, PGCPS, or BCPS school districts and download publication-ready map images for town halls or county council testimonies.
