Querying displayed layersΒΆ

HSLayers.Control.Query is tool, which enables to the user to point with mouse in the map at some place and perform spatial query. Following layer types are queryable:

  • OGC WMS with capability to display information in text, html, GML or other format
  • Vector layer of any type, such as KML
  • Proprietary MapServer layer (not only point, but also box query is allowed).

It works in very straight-forward way. User does not need to take care about layer query type or server output format. HSLayers tries to display result of the query in a grid form, if possible. All visible layers are queried automatically. Along with query result, mouse position is displayed as well, so that user can copy and re-use it.
