GeoServer is a software server that allows users to share and edit geospatial data. Designed for interoperability, it publishes data from any major spatial data source using open standards. GeoServer is the reference implementation of the Open Geospatial Consortium (OGC) Web Feature Service (WFS) and Web Coverage Service (WCS) standards, as well as a high performance certified compliant Web Map Service (WMS). GeoServer forms a core component of the Geospatial Web.
Geomajas is an extensible spatial application framework, enabling integrated GIS solutions for businesses and government. It has an integrated client-server architecture, with a high focus on server-side integration of your data (be it through GeoTools or Hibernate). This means that you apply your security and business logic on the server before anything gets sent to the client, resulting in robust applications and a real thin client.
Whiteboard lets the user draw freehand graphics on a Web page. It can create a canvas object for the whiteboard (if one does not exist) and let the user draw on the canvas area by dragging the mouse around. The color, thickness, line join, and line cap of the drawing pen can be configured. The object can also clear the whiteboard, export the coordinates of the drawn lines, or import previously drawn lines.
Gestures is an object that can recognize user gestures that form configurable shapes. It can listen to events of the user moving the mouse forming known gesture shapes. The object can recognize custom gesture shapes defined by a list of vertex points of the shape. A given callback function is invoked when the object recognizes a known user gesture shape. The object can also draw the gesture shape as the user moves the mouse.
Lightning effect JS is an object that can draw a random lightning bolt on the page. It can create a canvas on which a glowing random line similar to lightning bolt is drawn within given page boundaries. The position, color, and thickness of the lightning bolt are configurable parameters.
