Gravity Anomaly Maps and The Geoid - NASA Earth Observatory
Gravity anomaly maps (see globe below) show how much the Earth’s actual gravity field differs from the gravity field of a uniform, featureless Earth surface. The anomalies highlight variations in the strength of the gravitational force over the surface of the Earth.
Gravity anomaly - Wikipedia
Gravity anomaly map from GRACE. Currently, the static and time-variable Earth's gravity field parameters are determined using modern satellite missions, such as GOCE, CHAMP, Swarm, GRACE and GRACE-FO. [29] [30] The lowest-degree parameters, including the Earth's oblateness and geocenter motion are best determined from satellite laser ranging. [31]

World Gravity Map (WGM) denotes a set of 3 global anomaly maps of the Earth’s gravity field realized by the Bureau Gravimétrique International (BGI), a service of the International Association of Geodesy (IAG).
Gravity Data - National Centers for Environmental Information
The NCEI gravity database includes land and marine gravity surveys, grids, models, and geoids. Data parameters include latitude, longitude, Bouguer Gravity Anomaly (land), Free-air Anomaly (ocean), and observed gravity and elevation.

Summary : WGM2012 is the first release of a high resolution grids and maps of the Earth’s gravity anomalies (complete Bouguer, isostatic and surface free-air), computed at global scale in spherical geometry.
Gravity Anomaly Map Using GRACE Data
This map from September 2015 shows deep drought in California, Nevada and Texas.
Gravity map - Wikipedia
Mars free-air gravity map. Venus gravity anomaly map. A gravity map is a map that depicts gravity measurements across an area of space, which are typically obtained via gravimetry. Gravity maps are an extension of the field of geodynamics.
