Interactive Map

The CRI Interactive map is no longer functioning and there are currently no plans to update it due to lack of funding. Please visit the Thematic Viewers or Advanced Viewer on CTECO for interactive maps of Connecticut Natural Resource Data.



If you are familiar with Interactive Mapping (ArcIMS), feel free to

Two Important Tips

If your map gets hung up or you click too fast and break it, hold the CTRL button and press F5 to reload.

Legends (Two things)
Print out the Legends page (pdf) to go with any map you create on the Interactive Map.

Click on the swatch next to the layer name to see the legend for that layer (right).

The Basics

The interactive map has several parts. The Map display is the biggy because, well, it displays the map. The Table of Contents, on the left side, is where all data layers are listed and where they can be turned on and off. The tools are located across the top. Along the bottom is a window used by several of the tools including the Print to PDF tool and the Identify tool.


Layer Groups. The data layers are arranged in Groups according to the Community Resource Inventory Map Sets. To expand any group, click the arrow Right Arrow.

Closed Group
Open Group

On and Off. A data layer is turned "on" when there is a check
next to it. Click in the gray box to turn any layer or or off.

To the right, Major Roads and Named Lakes are turned on and the other layers are off.

Base Layers

Refreshing the Map
By default, "Auto Refresh" is checked. This means that each time you turn layers on and off, the map will automatically redraw. You can uncheck Auto Refresh if you prefer. Sometimes if you click too fast, the map will not catch up. Click the Refresh button in these cases. If you manage to break it, reload the map by holding down the CTRL key and then pressing the F5 key (top of the keyboard). Refresh

There are three ways to view legends. The first way is
to click on the color swatch to the left of any data layer
to view the legend for that layer (below).

The second way is to click Legend/Layers on the toolbar. This hides the Table of Contents and shows a Legend for all layers that are turned on (right). Click Legend/Layers again to bring back the Table of Contents.

The third way is to view and print a pdf of all the legends by clicking here.

Information About the Data Layers

Click on any data layer to go to the metadata page of the CRI. Nothing will open if you have pop-ups blocked. If this is the case, hold the CTRL key while you click and the page should open.

The images are set so that only one layer in the images group can be checked on at a time. This is because images cover every bit of the map and there is no way to see "through" an image. If both topography and land cover were turned on, the topography would completely hide the land cover. This is also why the images are at the bottom of the Table of Contents. Images

Scale Dependency
Several data layers have set scale dependencies. This is because they have too many features or too much detail to draw when zoomed out. You know a layer has scale dependency when it has been checked on but a checkmark doesn't appear. Instead you see Scale Dependent. Zoom in further and this layer will draw. The 2004 Aerials layer is highly scale dependent because the aerials are uncompressed, large files with great detail. Aerials

Print Map
Click on Print to PDF to create a map layout that displays your custom map. The layout (the parts that don't include the map itself) is consistent with the map layout used for other pdfs in the "Build Your CRI" section. After pushing the Create Layout button, you may need to wait a bit and then the layout will be available at the link. Click the link to open the pdf in a web browser. From here, you can view, print or save the pdf. To save, click Pdf Save A Copy, give the file a name and save it to your computer. Notice, also, that other formats are available on the dropdown menu besides pdf. Pdf Menu Map Layout

Zoom In. This tool is selected when the text is bright blue Zoom In selected. You will also notice that the mouse changes to cross hairs. You can either click once to zoom in on the clicked spot OR you can use the mouse to draw a box to zoom to the approximate area covered by the box (right).

Zoom Out. This tool is selected when the text is bright blue Zoom Out on. You will also notice that the mouse changes to cross hairs. You can either click once to zoom out from the place you click OR you can use the mouse to draw a box to zoom out the approximate area covered by the box.

Full Extent. Clicking Full Extent returns the map to its full area which is the state of Connecticut.

Zoom Back returns you to the previous extent. If you accidentally zoomed in or out way too far, this is an easy way to get back.

Pan. This tool is selected when the text is bright blue Pan Tool on. You will also notice that the mouse changes to four arrows. Pan lets you drag the map and move around. Make sure the Pan tool is selected, move the mouse over the map, then Click (hold it - don't let go) and drag the mouse to move the map. Let go.

Identify All. Every data layer in a GIS contains features (all the shapes on the map) and every feature has information behind it. The information is stored as attributes. The Identify tool displays the attributes associated with the displayed features (the layers turned on) at the exact spot of your click.

In the example (right), DEP property is green and Named Lakes are blue. After the Identify tool is selected (you know because the text turns bright blue Identify On), and you click on the map where the black cross hairs are, information is returned below the map (example below). Here, features from three layers were returned.

Identify All Results

If a layer was visible and you clicked at a place where there were no features, the result would say "No Features found."
