Getting Started

Zoom in and out of the map using the + and - tools located in the upper left hand corner of the map.

To move around the map, click on the map and hold the left mouse button while dragging, then release the left mouse button. This pans the map to different areas, but does not change the zoom.

If you get "lost" on your map and need to go back to the big picture, use the Initial View or Full Extent button.

Basemaps

A Basemap draws below the other layers in your map. The Connecticut Base Map is on by default. To change the basemap, click on the Basemap Icon in the lower left hand corner of the map and choose one. Although not technically listed under the basemap button, any of the Elevation or Imagery layers can be turned on in the Table of Contents and essentially function as a basemap.

Overview Map

The Open and Close Overview Map icon is in the lower right corner of the viewer. Click to open and show the map and click to close it.

 

Layers and the Table of Contents

Layer List

The Layer List is contained in a panel on left side of the viewer. To open the Layers panel either click on the Layers tab in the lower left corner of the viewer OR click on the Layer List button on the Map panel at the top.

Layers are listed in Groups. Click on the plus to expand a group. The group needs to be checked in order for layers inside it to be visible .

In this example, the Open Space Group is checked on as well as the Protected Open Space Mapping layer inside the group. The other layers are not visible.

Expand as many groups as you like and turn on (make visible) any combination of layers. Remember that layers draw in order. Layers higher up on the list will draw above (on top of) layers below it. Layers often overlap so may cover each other up. If this is the case, use transparency or turn the layer off.

Layer Actions

Many layers have a chevron to the right of the layer name in the Table of Contents which opens Layer Actions. Clicking on Layer Actions opens a panel that contains options like Zoom to full extent (of layer), Zoom to visible scale (of layer), link to a Data Guide if there is one and link to Metadata. At this time, raster layers like elevation and imagery do not have the layer actions option. To close the panel, click on the in the upper right corner.

Transparency

Transparency makes a layer partially or fully see-through. Transparency can be adjusted on some layers by moving the transparency slider next to the layer's name.

 

Legend

From the Layers panel, click on the Show Legend icon at the top right of the panel. Click on Show Layer List to open the Legend panel. The panel shows the legend for all layers that are turned on (checked) in the table of contents. To CLOSE the Legend, click on the at the top of the Legend panel to return to the Layers panel.

Symbology, or the symbols used for a layer (which is also shown in the legend) can be viewed in the table of contents. Click on the Legend info icon to the left of the layer name to show the legend. In the case where only one symbol is used in a layer, that symbol is visible instead of the legend information icon.

 

Tools

Bookmarks

Use the Bookmarks button to save specific extents during your session. Bookmarks make it easy to jump around the map to areas of interest. First, zoom to an area of interest then click the bookmarks button. Choose Bookmark Current Extent and give the bookmark a name. The named bookmark will remain in the list even while you move around and work with the map.

The Query button opens the Query panel to guide the query building.

  1. Choose the Data Source (layer) to query. The list is based on all layers that are available in the viewer.

The choices together create the query. Click search to find all cases that meet your query. All cases are listed with a pinpoint. Alternatively, view the results in a table by clicking on the Panel actions icon and choosing Switch to Table. The table is a good way to click on the results and view them on the map.

  1. Create the Filter by first choosing the Data Source or layer.
  2. Once a Data Source is chosen, all available attributes are listed in the Select filter dropdown list. Choose one.
  3. Once an attribute is chosen, operators are listed in the Select operator dropdown based on if its a numeric or text field. Choose one.
  4. Finally, any values assoicated with that attribute are listed. Choose one.

The choices together create the filter. Click Filter. If you are viewing the layer, you will notice that only the features meeting the filter criteria draw. If you are not viewing the layer, nothing happens! But when you turn on the layer, you will notice that the filter is being used.
