Map View: Importing Overlays & Radial selection (2.8+)

    New in 2.8: import additional datasets into a Map view and show as overlays on top of the chosen base map.

    Configurable "Point" overlays show the additional dataset as reference points beneath the main data's markers. The "Spider" option shows links between overlay datapoints and main datapoints, such as linking the sales person to the customer.

    "Line" overlays (where the additional dataset is a series of lines, each represented as a series of points) allow you to show routes, for example.

    "Area" overlays (as per "Line", but where the path is closed and filled) allow you to show political or administrative areas, areas at risk from natural disaster, or areas within a certain distance of another area or point, for example.

    All overlays are highly configurable and can be data-linked to the main datapoints - so overlay data will disappear or re-style as you filter in the sidebar.

    You can also use area overlays to select data (by optional join field, or by geometry).

    Note that the Map view's "Connect by" menu has also been extended to support equivalent additional functionality such as filled areas.

    We have also introduced a Radial selection mode, allowing you to drag from a centre point outwards to select all points accurately within a given distance.

    All overlays currently assume WGS84 coordinates.
