SPATIAL COVERAGE OF TYPE “physiographic features” IN THE ADL GAZETTEER

---

There are 575,964 items of type “physiographic features” in the ADL Gazetteer as of January 25, 2001.

The spatial coverage of the items is graphically shown by the tiled map below. Each tile represents a 10° × 10° area of the Earth's surface. The color of a tile reflects the number of items that overlap that tile; the lighter the color, the more items that overlap. The legend to the right of the map shows the correspondence between color and number of items.

The following table shows the spatial coverage numerically. Each cell in the table represents a 20° × 20° area of the Earth's surface centered at the indicated latitude and longitude. The value in a cell is the number of items that overlap that cell.
