User notes for Qld Community Intelligence Map (CIM)

December 6, 2011

Geospatial, How To...

Novice users of the new Queensland  Community Intelligence Map (CIM) can stymied by the small things.  For those who are comfortable using Googlemaps the CIM is very intuitive, but to make GIS more accessible to a wider audience sometimes a newbie starter kit can help! (This will be a work in progress…I’ll try to add content when I find time )

1. The “More Information” box

OK, so to begin.  The box on the right, labelled “More Information”,  is  what is sometimes called a “Layers” box in GIS-speak.  It shows  the layers of information on the map that you can control and make visible,  turning “on” or “off”  by checking or un-checking the box.
Tip:  If you check the box and see nothing on the map there are several possible reasons.  One possiblility is that there is no data for the geographic area you are looking (for example, Traffic Cameras data is only available in the Brisbane metro and Goldcoast area). Another likelihood is that you need re-zoom. This is because layers are preset to only display at certain map extents.   If this happens to you, try zooming in or out of the map.
CIM User Note 1

Some layers are pre-set so that they can only be viewed when you zoom in.

(Slightly) Technical Note: There is a good  reason why layers such as the Disaster Districts  are set to turn off when the map is viewed at a small scale (ie zoomed far out).  This  is because when you are looking at the entire state of Queensland the Districts would completely fill the map with red clutter and would not provide useful information . (Google “Map Scale” if you want to dig deeper)

Traffic Cameras – The CIM provides Web Camera Integration, giving users the ability to access an XML data feed for Traffic Cameras from the Queensland Department of Transport.  The Traffic Cameras import live traffic camera images, updated every minute, from Brisbane and Gold Coast metro locations. Click a camera to zoom the map to the location and see a live image of the traffic conditions. Click on a camera to open the viewer. You can maximize the camera view or close it again using the [x] box

Tip:  The image does not automatically refresh.  Look at the time stamp on the image:  If it is older then one minute you may want to close and re-open to update the content.
