View does not display places without coordinates

Note that, like all GeographyGeography View modes, ONLY the Places with a defined Longitude & Latitude will be plotted.

Ancestors Map Geography view

This GeographyGeography Category addon view mode plots tagged pins on a Map at the Places associated with Ancestors of the Home Person.

Ancestors Map is an interactive Charts Geography category view addon that overlays pins for certain known Places on downloaded Map tiles.


Change the designated Home Person before changing to the Geography Category view to map the Event Places associated with a different Person's Ancestors.

There are 4 pin types:
Still looking for correct pins. This map use left-handed versions of the normally right-handed magnifying glass.

Pin Description Place types
Gramps-zoom-in.png Zoom-in Magnifying glass Places with Birth Events
Gramps-zoom-out.png Zoom-out Magnifying glass Places with Death Events
Gramps-zoom-best-fit.png Magnifying glass pins with an X Places with Marriage Events
Gramps-geo-mainmap.png Green Push pins Places with multiple Event types

Right-click on a map pin to reveal a pop-up menu listing the Events & People at that Place.


Places of Ancestor Events that do not appear as pins on the map are probably missing the correct GPS longitude and/or longitude. Determining which Places are missing and need correction can be finicky work. This is most easily done with custom filters... but it takes multiple stages.

The objective is to find the Places of Events of Ancestors of the Home Person. That's 4 stages of filtering.

You can set up a multi-stage of filter that shows only Places for Ancestors & configure the Places Category view to show the Longitude & Latitude columns. This will tell you how many of Ancestor related Places will be omitted from being plotted on the map.

For this multi-stage custom filter, create the following Cascade of custom filters:

  1. Create a Person custom Filter "ActivePerson" using the "Active Person" add-on Person General rule.
  2. Person custom Filter "ActiveAncestors" using Ancestral filter "Ancestors of <filter> match"; filter=ActivePerson
    You might add a 2nd rule to include the Active Person and then select the "At least one rule must apply" option. Otherwise, the Events & Places of the Active Person might be omitted
  3. Events custom Filter "ActiveAncestorEvents" using Events General filter "Events of persons matching the <person filter>"; person filter=ActiveAncestors
  4. Places custom Filter "ActiveAncestorEventPlaces" using Places General filter "Places of events matching the <event filter>"; event filter=ActiveAncestorEvents
Making Filters that are more reusable

You could built this using a Person custom filter set to the built-in Default Person (a.k.a. Home Person) General rule. That would more directly correspond to this add-on Geography view mode.

But a custom Filter using the "Active Person" add-on Person General rule is much more flexible. It stays synchronized to the Person being edited instead of continually resetting the Home Person designation or editting a rule that had been preset to a specific PersonID.

Download and use the incredibly useful add-on Person General Rule that was created in early 2020. It replaces the awkward PersonID based rules and makes Custom Filters MUCH more dynamic. Thanks Paul!
