URL parameters in Hajk

Here's a quick overview of the URL query string parameters that Hajk uses:

Example of the string as shown in the browser address field:

#m=ext&x=110600&y=6283796&z=2&l=58%2C100&p=layerswitcher

Explanation:

• #: the list of parameters always starts with this character
• m: name of the map file (as displayed in Admin)
• x and y: center coordinates in the projection of the map (refer to map configuration in Admin to determine your choice of projection)
• z: zoom level (an integer between min and max zoom as specified in Admin)
• l: list of IDs of layers and group layers. IDs are delimited by a comma which is URL encoded (hence %2C)
• p: name of currently active tool(s)
• q: loads Hajk with the search tool active and the value of q provided as the search term
