Are there any tools for interactive testing and prototyping?
A sample HTML file located in the map_server directory, glg_map_display.html, provides an example of an HTML and JavaScript-based GIS viewer. It allows the user to zoom and pan the map, change projection, select map layers to be displayed and change various map parameters. When the user clicks on the map, the script uses AJAX to query the map server and display the lat/lon coordinates of the mouse click. The HTML viewer requires setting up the GLG Map Server on a web server. To use the viewer, edit the map_server_url and map_script parameters in the HTML file to point to your web server setup. The GLG Graphics Builder may be used to prototype, test and debug Map Server setup interactively without setting up a web server. The Graphics Builder enables you to create a GIS object to display a map and change all parameters of the map request interactively. The Builder’s interactive zooming and panning capabilities allow you to test the map setup and automatic layer switching. The Builder al
