With JS-GIS, the user is able to:
Please have a look at the JS-GIS sample page at http://jsgis.sourceforge.net/demo to see how a JS-GIS data browser looks like.
Basically, JS-GIS consists of:
GIS data is exported (published) into the following formats:
The geographic area of interest is subdivided into tiles as if it were a chessboard; this subdivision is done for each of the zoom levels defined by the publisher. The export files are generated according to nomenclature and disk location rules: tiles are located according to the zoom level and the map theme and named after row and column position in the "chessboard", while HTML data files are referred by means of the map objects IDs (primary keys), so they usually need to be named following the objects IDs.
The JS-GIS API allows to build a user interface to the published data, by means of:
The JS-GIS engine allows for some dynamic operations, such as geographic indexing, point location, dynamic vector object loading (limited to points).
JS-GIS allows to build quickly a simple query interface to geographic data; but being an API, allows for great flexibility and control, too.
