Historical tracts and grocery access: Layers → Census Tracts (2010) draws independently styled outlines on native 2010 Census polygons. The existing 2020 Census Tracts layer remains separate. The 2010 outline is off by default. In Browse Metrics, search LRAM in the ordinary metrics table to see all 21 individual USDA 2019 indicators, alongside other published metric series. Selecting an LRAM metric colors the 2010 tracts even if its outline is unchecked; no 2019 values are projected onto 2020 tract polygons. LRAM 2019 measures access to supermarkets and large grocery stores using 2010 tract definitions and 2014–2018 low-income context; USDA 2025 SRAM uses 2020 boundaries and a different retailer definition, so the two are not directly comparable as a trend. For LRAM Yes/No flags, the legend distinguishes zero, one and missing; missing is never treated as zero. The historical source and tract vintage appear in map tooltips, legends, detail popups and downloads. Large selections use paged, simplified boundary shapes; closer zoom shows original TIGER/Line polygons where available.
For a newly chosen numeric metric, Equal numbers of areas puts approximately the same number of counties or census tracts in each color. Equal values stay together, so class counts can differ. Equal value ranges instead gives each color the same numerical width; an outlier can leave most areas in one class. All selected counties determine the ranges, regardless of zoom. Gray means missing data, not zero; the legend reports each class count and the total number of areas.
Lock bucket ranges when counties change freezes the exact numerical boundaries for comparison. Adding or removing counties then changes the class counts, including empty classes, while the cutoffs stay fixed. Unlock to calculate fresh boundaries. Changing the metric, year, geography, number of colors or grouping method releases the lock. Clearing all counties retains a locked scale until counties are selected again. Saved, shared and duplicated maps keep the method and locked cutoffs. Older saved maps retain their original grouping until you choose a method. Yes/No metrics keep their binary display and have no grouping or lock choices.
Food Programs is alphabetical in Points, immediately before Food sources. Restore default styles resets only Points marker appearance, including the seven food children; it keeps checked categories, Organizations, the view, metric colors and other settings. It marks the draft changed and saves only when you explicitly save. Geographic metric tooltips put the area name on the first line and the metric on the next; use keyboard focus or tap an area for accessible details. Downloads wait for the current map data and use its classification and legend.
In Points, Food Programs selects or clears all seven food categories. Show categories opens the individual choices; a mixed checkbox means only some are selected. Each category starts with the same map-pin shape and a distinct color. Use its style sample to change shape, color, size, opacity or grouping. A food site belonging to several selected categories appears once; the first selected category in the list supplies its style, and its details show all food memberships. Street Feeding & Outreach is unavailable when the selected area has no existing verified map points. Programs without public locations can still appear in the county Food Resource Guide. Food category choices and styles are remembered in saved maps.
In Circles, choose a radius, Add circles, pan or zoom as needed, then click or tap the map to place each circle. Click the style sample to rename or adjust its colors. Escape or Finish adding exits placement.
Changes to counties, public layers, metric colors, organization points and roads update automatically; data-backed layers may show Updating while results load. Save Map is still a separate action, and Retry unavailable layers is offered if a source fails. Tract metric colors have no built-in borders; check Layers → 2020 Census tracts to draw independently styled outlines, or leave that layer off to show ZIP-code boundaries over metric colors. Adjust tract outline width, color and opacity independently. Browse Metrics to search validated canonical public metrics. Duplicate source batches are reconciled without losing approved counties; true year, subgroup, source, and county/tract variants remain separate. Select a metric row, then use the dark-green Show selected metric on map button at the upper left. A county estimate colors the whole county, not tracts. Sorting and reference-year filters do not change underlying observation data. The Metrics option Suppress best bucket displays the best-ranked area in white without changing data and is remembered when you save or reopen your map. Drag or use arrow keys to pan; use + and − to zoom. Tap a visible tract or location for details. The Point-layer Shape picker also offers a classic teardrop Map pin with its tip at the location. Unchecking Group nearby points keeps individual site markers at their exact coordinates, even if they overlap; the Overlapping point locations panel inside Organizations lets you open concealed sites. Opacity sliders read Transparent on the left and Opaque on the right. Missing data is not zero. Map settings use live data when reopened; they are not historical snapshots.

Cities, directly below County seats under Labels, initially displays all Florida municipalities in the selected counties. Search and Add to switch to a custom subset. Search by incorporated place name and filter by city, town, village or county. Pins represent 2025 Census internal place points, not city halls or municipal boundaries; some municipalities span county lines. Selected Census GEOIDs remain in saved and exported maps. Unavailable layers and changed source vintages are reported. Conservation shading does not imply public access. Roads are simplified reference lines, not navigation directions.
