New query string parameter polygon_threshold=<0.0..1> is introduced. The float value of this parameter (defaults to 0) is passed to ST_SimplifyPreserveTopology() on geometry we're about to output in one (or many) requested formats such as GeoJSON, KML, etc. This is useful when getting border polygons for whole countries, but rendering them at large scale, when most of the high resolution details cannot be seen anyway. For example, the unsimplified polygon data for Germany in GeoJSON format currently makes for about 3 MB response body. With use of this new parameter, the application can greatly reduce the amount of downloaded data and server response time while providing its users with the same picture. On a typical laptop screen resolution, zooming out to fit the whole country borders on screen, only 1/100 amount of details could be well enough. |
