Viewing and Editing Maps
All available maps can be found under the Maps tab. When a map of interest is found, clicking on the title will open a viewing window very similar to the layer viewer described in Viewing and Downloading Layers. This view provides a quick view of the map and metadata information.
Viewing a Map
The View Map button opens the larger map viewer. This viewer allows editing of the map, including adding or removing layers, changing the basemap, changing layer order, etc.
The Layers tab on the left of the map shows all layers on the map (listed under ‘Overlays’) and all available basemaps (listed under ‘Base Maps’). Layers can be turned off by unchecking the box next to each layer, which will temporarily remove the layer from the map.
Changing Base Maps
Base maps can be changed by clicking the radio button next to the base map of interest.
Identify/Get Feature Info
The Identify/Get Feature Info tool functions similarly to the Get Feature Info tool described in Viewing and Downloading Layers.
The Measure tool functions similarly to the Measure tool described in Viewing and Downloading Layers.
The query tool can be used to return features of the selected layer that are either inside the current map extent or match an attribute search. The current layer – the one that is highlighted in gray on the layer panel – is the one that is queried. The query box appears at the bottom left of the screen, and results are returned to the right of this. Either of both of the query options can be chosen using the check boxes.
- Current Map Extent: Features of the selected layer within the map extent will be returned. Changing the map extent will change the result of the query
- Attribute Search: Features matching the attribute search terms will be returned. One or more attribute filters can be created. Note that search terms are exact and case sensitive (so ‘Atna’ or ‘atna river’ will not return a result of ‘Atna River’).
Maps can be printed to PDF using the Print button. Here you can select the paper size as well as the resolution of your map.
