Data Layers

You can customise your map view by overlaying different data layers in order to give you the combination of information you need.

Customising allows you to:

  • access a range of different map views
  • apply different data layers to your map view – the default displays all ESTA incidents
  • create a record of information captured during an incident that can be accessed and reviewed

Which map view to use:

If you want to see… then the Map view to use is…
 a clear presentation of streets in 2D  VicMap Cartographic
 real features, including major infrastructure  VicMap Satellite
 countryside and roads in 1D  VicMap Book by Spatial Vision
 countryside and roads in 1D in grey so coloured
shapes and lines you add stand out
 VicMap Book by Spatial Vision in greyscale
 urban layout and roads in 1D  Melways
 geographic areas outside Victoria  Google or Open Street Map
 topography in 3D with streets  Google Physical
 detail features in the landscape  Google Satellite
 detail features in the landscape with road names  Google Hybrid
 a comparison to the VicMap Book maps  Google Streets
 a comparison to the Google Street map  Open Street Map

Data Layers
Data layers are the geo-information that can be placed on top of the Map layer.  Layers are turned on and off by checking and un-checking boxes next to their name. You may also shut off all data layers by clicking the “Turn Off All Layers” button at the bottom of the drop down menu.

Data layers are organised in a tree file structure.

GIS Users and Administrators can import data layers under the “Data” menu. This creates new data layers in the “Upload” folder.

Use the double arrows >> to View Active Layers and View Active Legends.

Tracking Layers:
Tracking layers, unlike data layers, are very dynamic and designed specifically to allow the mapping/plotting of GPS-enabled devices within  EM-COP. These are usually based upon near-real time data feeds from instrumented vehicles, aircraft, apparatus, and personnel, also called Automated Vehicle Location (AVL), Automated Flight Following (AFF) and Personal Location Information (PLI). Some uses for Tracking layers are for managing units in a field, following a moving target, or just marking hotspots of activity while in the field.

Weather Layers:
Weather layers are also dynamic layers related to current meteorological conditions. They can be turned on and off from the weather menu in the upper right corner of the map.
