Montana DEQ Layers
These Map Layers represent information collected and maintained by the Montana Department of Environmental Quality (DEQ). Montana DEQ Layers that are made visible will be those whose items are searched for within a specified distance of the Map Note coordinates. Please see the Map Notes section of the Help for more details on this type of search.
Reference Layers
These Map Layers are used for reference and provide more context to the map than just the chosen Basemap.

The viewable and searchable area of the map is confined to the State of Montana. The map will not let you move too far away from its intended spatial focus of helping you understand Montana's environment.

Many different basemaps are available to choose from to use as the base or primary layer for all other Map Layers to sit on top of.
Basemaps can only be used one at a time and but can be viewed at any map scale to help you understand the spatial context of the Map Layers you have turned on.

By clicking once with your left mouse button on the map a pop-up information window will appear providing details "About This Location".
Along with coordinates that become more defined the further you are zoomed in you will be provided with specific information about features found within its included Map Layers.

Find Features Around the Identified Location
Just below the declared Latitude & Longitude coordinates in the "Location" tab you can search for items in the Montana DEQ Layers you've made visible. You can then specify a search radius up to 30 miles of that location. A results window will show you the items found within your search area. Individual Feature Reports
Some map layers will present more detailed information via their own tab. These specific Map Layer information tabs may provide the count (#) of those features found at that location as well as more details about each item found within that layer.
Pop-up Window Locatino
The pop-up About This Location window is not a floating window on top of the map, but anchored within the map at location you clicked. Depending on the size of your monitor and screen resolution, the Map Note may be rotated around its anchor point in a way that places it in a area of the map not currently in view. If this happens, pan or move the map to encompass the area the Map Note is anchored to.

You can search for specific mapped features or locations in the map via the Search menu above the map window.
Search for Address
You can search for a town or specific street address in Montana. The address search engine will place a marker on the map at the location found and provide you with the formatted address that best matches your search.
Search for Coordinates
