Change the basemap (satellite view)

1. Find the basemap switcher in the top-left corner of the map, just below the zoom buttons.
2. Click Satellite for aerial imagery, OpenStreetMap for a general-purpose street map, or Streets to return to the atlas's built-in map.
3. Your choice is remembered for the next visit. Streets works offline; the other two stream from the internet.

Switch between Basic and Advanced mode

1. Use the Basic / Advanced toggle in the top bar.
2. Basic keeps six core layers with plain-language names. Advanced unlocks every dataset, variable switcher, filter, and the report builder.

Turn on dark mode

1. Click the moon icon in the top bar. Click the sun to switch back.
2. The basemap, panels, and charts all follow the theme.

Turn layers on and off

1. Open the Layers panel (on smaller screens, tap the Layers button; on desktop it is the right-hand panel).
2. Layers are grouped by topic — Flooding, Extreme heat, Severe weather, People & vulnerability, Context. Click a group header to expand it.
3. Tick a checkbox to add the layer to the map; untick to remove it.

Show or hide place-name labels

1. Expand the Context group at the bottom of the layer list.
2. County, city, and town labels are separate layers — tick exactly the ones you want.

Change a layer's colors, line width, or opacity

1. Find the layer in the Active layers widget in the bottom-left corner of the map.
2. Hover the layer's row (on a phone the buttons are always visible) and click the pencil.
3. Adjust color, width, and opacity — the map updates live. Revert to default style undoes everything.

On a phone, the pencil opens a full-width editing sheet above the map so the color picker has room.

See what's on the map, and remove layers quickly

1. The Active layers widget in the bottom-left corner lists every layer currently on the map, with its legend.
2. Click the × on a row to remove that layer. Click the widget's header to collapse it out of the way.

Pick a scenario, time period, or filter

1. When a layer offers choices, they appear right under its checkbox.
2. Projected heat and projected rain have baseline / mid-century / late-century time periods; observed heat has AM / afternoon / evening; storm events have type and decade filters; SVI and demographics have variable dropdowns (Advanced).

View buildings in 3D and tilt the camera

1. Building footprints are on by default (Context group) and appear once you zoom to level 15 or closer.
2. Under the Building footprints checkbox, switch the 2D / 3D toggle to 3D.
3. Buildings extrude to their estimated heights.
4. To tilt the whole map into perspective, right-click and drag up or down (on a phone, drag up or down with two fingers — pinching still zooms). The basemap, flood zones, and every other layer tilt together, and buildings stand up out of the tilted ground.
5. Drag back down to flatten, or switch to 2D — that always resets the view to straight down.

Get details and charts for any spot

1. Click anywhere on the map. A window lists every active layer at that point — one section each, with charts for historical, current, and projected values where the data supports it.
2. Hovering a feature previews its numbers in the top-right corner box without clicking.

Expand details full screen, print them, or download CSV

1. In the click popup, press any maximize button (top-right corner, next to a section title, or the bar at the bottom).
2. The full-screen view has Print / PDF for a clean document and Download CSV for every number on display.
3. On a phone, clicking the map opens this full-screen view directly.

Read a neighborhood's combined report

1. Click any census tract on the map.
2. The Tract readout in the side panel combines vulnerability, population, income, projected heat, and plain-language flags for that neighborhood.

Create an advanced report

1. Switch to Advanced mode (top bar).
2. In the side panel, click Build a report.
3. Pick a scope — the whole region or one jurisdiction — and tick the sections you want. The preview updates live.
4. Print / PDF makes a clean document; Download CSV exports the tract-level table behind it.

Use the atlas on a phone

1. The layer panel becomes a bottom sheet — open it with the Layers button, swipe the list inside it.
2. Tapping the map opens the full-screen details view directly, with print and CSV built in.
3. Styling a layer opens a full-width editing sheet, so the color picker and sliders are easy to hit.
