Your ArcGIS stays the source
Nothing changes for the NSTA’s GIS team. Data keeps being managed in ArcGIS; this site reads it, can refresh on a schedule, and gives users a faster way in: one dataset per layer instead of one per coordinate system, search across everything, maps that load instantly, and queries that run in the browser.
