{# Viewer routes (/catalogue/#/dataset/4, #/map/new, #/metadata/4...) are known from the URL before MapStore loads, so mark them at first paint: the footer stays hidden and the header is full width from the start, instead of the footer showing under the header and the header jumping when the viewer mounts. #}
Published map compositions — catalogue layers styled, stacked and framed for a specific question. Open any map in the viewer, or copy it as a starting point for your own.
