<p>UTFGrids can be used to output highly optimized feature "hit grids."
|
|
The UTFGrid encoding scheme encodes interactivity data for a tile in a
|
|
space efficient manner. It is designed to be used in browsers for
|
|
interactive features like displaying tooltips without having to hit the
|
|
server for an "info query."

|
|
detail on using UTFGrids in OpenLayers. For more info, view the
