Description

The United States Census Bureau regularly releases a geodatabase named TIGER. This dataset contains the 2020 census blocks, roughly equivalent to a city block. There are just over 240,000 polygon features covering the United States, the District of Columbia, Puerto Rico, and the Island areas.

For full technical details on all TIGER 2020 products, see the TIGER technical documentation.

Visualize as a FeatureView

A FeatureView is a view-only, accelerated representation of a FeatureCollection. For more details, visit the FeatureView documentation.

var fvLayer = ui.Map.FeatureViewLayer('TIGER/2020/BG_FeatureView');

var visParams = {
  opacity: 1,
  color: {
    property: 'AWATER',
    mode: 'linear',
    palette: ['d8d9d9', 'aaaaaa', 'b6dfe9', '2ea3f2', '0c71c3'],
    min: 0,
    max: 1e7
  }
};

fvLayer.setVisParams(visParams);
fvLayer.setName('Water area by US census block group');

Map.setCenter(-74.0637, 40.6852, 13);
