Initial view: The map opens zoomed to the full Town of Wolfeboro extent. Every parcel is drawn with a thin 0.75 px yellow outline so the base revaluation layer stays legible against the imagery basemap.

Search: Open the Search panel from the header and enter an address (e.g. 289 Center Street), an owner name, or a Map/Lot/Sublot identifier. The map zooms to the parcel and highlights it in cyan.

Click: Click any parcel on the map to see its attributes in the sidebar. If the location contains multiple overlapping records (common for condominium buildings — some sites have 100+ units), a pager is shown so you can step through every account.

Home: Click the Home button (top-left) to reset the view to the full Wolfeboro extent.

When a click or search returns more than one record, the sidebar displays a results pager at the top showing the total count (e.g. “107 records found”).

Chevrons: use the ‹ and › buttons to step one record at a time.

Jump to record: type a record number directly into the input between the chevrons and press Enter to jump to that account.

Current-record emphasis: the active parcel is drawn with a bold magenta outline on top of the cyan group highlight, so it stands out among its neighbors. The map auto-pans to keep the active parcel in view.

Once a multi-record result set is loaded, the following shortcuts are available:

Scale dropdown: choose a standard engineering scale such as 1” = 200’, 1” = 100’, or 1” = 50’ from the dropdown in the header (or in the sidebar on mobile). The map snaps to that exact scale.

Arbitrary scales: the map view has tile-LOD snapping disabled (snapToZoom: false), so the selected scale is applied precisely rather than rounded to the nearest tile level.

Map Information button: the button in the bottom-right corner of the map opens a dialog showing the current Scale, Zoom level, and WGS84 Extent coordinates. Each value has a Copy button that writes the value to your clipboard — useful for sharing views or including a specific extent in a report.

The Filters & Themes block in the sidebar narrows the map to specific properties. Filters are cumulative — they combine with AND.

Tax Impact: show parcels whose 2020 tax changed by a specific percentage band.

Land Use: show only parcels of a given property type (Single Family Home, Commercial L&B, etc.).

Reset All: clears every filter, restores the default theme, and zooms back to the town extent.

The measurement toolbar sits in the bottom-left of the map. Measurement results render inside the sidebar, below the attribute panel.

Distance: click to start, click to add vertices, double-click to finish. Units: US feet.

Area: click to outline a shape, double-click to finish. Units: square US feet.

Clear: removes the measurement from the map and sidebar.

The layout adapts automatically at a 768 px breakpoint:

Desktop (≥ 768 px): the attribute panel sits on the left of the map. Drag the right edge of the panel to change its width.

Mobile (< 768 px): the attribute panel docks above the map at a 50/50 split. A drag handle (the small pill at the bottom edge of the panel) lets you resize the split anywhere from 120 px tall up to 85% of the screen. The Scale dropdown is duplicated into the sidebar so it stays reachable without opening the header menu.

Full-window parcel view: on mobile, when a parcel or multi-record set is opened, the attribute sheet expands to fill the entire window for comfortable reading — the same pattern used by the ArcGIS Map Viewer. Tap the × in the upper-right of the sheet to return to the map.
