geoportale salerno: timeline istituzionale webGIS

Historical timeline infographic titled "Evoluzione del Geoportale Comunale di Salerno". Create a VERTICAL timeline ribbon as the dominant visual, centered on the launch and modernization of the piattaforma geospaziale comunale di Salerno, Italia, in era contemporanea. Use 5 milestone events only, each with precise date, short heading IN Italian, one-line caption IN Italian, and a clear visual cue tied to digital cartography and amministrazione pubblica. Since this is an institutional platform timeline rather than an empire, structure the ribbon around a modern civic evolution arc overlaid as: "Avvio → Sviluppo → Modernizzazione → Integrazione → Accesso pubblico". Include clean map-based interface mockups showing the costa di Salerno, rete stradale urbana, livelli di zonizzazione, sovrapposizioni catastali stilizzate, dati di pianificazione pubblica, and GIS dashboard panels without any real logos or trademarks. Add a small territorial inset map of southern Campania highlighting the Provincia di Salerno with the label "Provincia di Salerno" and, where relevant, a smaller municipal highlight labeled "Comune di Salerno".

Milestones to render along the ribbon:
1. "2006" — heading: "Avvio del SIT" — caption: "Nasce l'infrastruttura comunale per la gestione digitale dei dati territoriali." Visual cue: rolled map transforming into a wireframe grid map.
2. "15/09/2010" — heading: "Lancio del geoportale" — caption: "Il portale cartografico online apre la consultazione di carte tecniche e tematismi urbani." Visual cue: desktop monitor with coastline map of Salerno.
3. "2014" — heading: "Catasto e zonizzazione" — caption: "Si integrano livelli catastali, vincoli urbanistici e strumenti di piano in un'unica vista." Visual cue: layered parcels, zoning blocks, cadastral overlay.
4. "2019" — heading: "Modernizzazione webGIS" — caption: "Interfaccia più chiara, servizi più rapidi e consultazione tematica semplificata per cittadini e tecnici." Visual cue: modern browser window with toggled GIS layers.
5. "2023" — heading: "Dati aperti e servizi" — caption: "Il geoportale amplia l'accesso ai dati pubblici, alle mappe interattive e ai quadri conoscitivi." Visual cue: open data nodes, map pins, planning charts.

Include 3 key figures as generic professional roles, shown in small portrait medallions or side labels with exact Italian text: "Pianificatore comunale, 2006-2012", "Amministratore GIS, 2010-2019", "Responsabile innovazione territoriale, 2019-2023". Do not use real identities; portray them as archetypal municipal experts with professional attire, tablets, map sheets, and GIS screens.

Design notes: modern textbook diagram, monochrome textbook palette, grayscale with subtle charcoal, stone gray, white, and light silver accents; highly legible editorial layout; clean sans-serif typography; crisp date markers; thin connector lines; icon legend in Italian; neat callout boxes; sharp readable labels; understated civic-technical mood; precise contemporary institutional aesthetic. Include editorial historical illustration, textbook-grade clarity, period-appropriate imagery, vector-clean lines. All text MUST be written in Italian (it). Every heading, label, caption, legend and metric name in the image must be in Italian — not English. Spell each Italian word correctly using Italian characters and diacritics. Numbers stay as digits, no watermarks Render dates in Arabic numerals. Avoid graphic battlefield gore, no real death photos, no flags or symbols of hate movements. For contested historical narratives, present neutrally — no propaganda framing, no glorification of atrocities. Period-appropriate but tasteful.
