• To replace ECO, which will be discontinued on
  March 12, 2010

• To display data that may not be included in the
  new SIMS viewer

ECO Layers NOT In Envirodata

• Not Included for one of the following reasons

  Viewer
• are not included for other reasons, e.g. file
  size issues, lack of metadata, outdated data,
  etc.

Three Major Differences BetweenECO and Envirodata

• No Map Redraw Button
• The map redraws EVERY TIME you turn a layer on
  or off.

• Grayed Out Layers
• The layers are grayed out and cannot be turned
  on until you zoom in to the proper scale.

• No Environmental Conditions Report
• in Envirodata. If you need this type of report,
  use the SIMS Viewer.

8

• No Map Redraw Button

To minimize redrawing time, turn the category off
before turning new layers on or off. This will
stop the redraw until you check the category name
back on.
9
Grayed Out Layers
Layers are grayed out until the proper display
scale is reached. The check mark will
disappear at that point and allow you to turn the
layer on.
10
No Environmental Conditions Report
There is no Environmental Conditions Report in
Envirodata as there was in ECO.

Navigation Tools
Zoom In, Zoom Out, and Pan Use the mouse button
to click, drag and release to zoom to a
specific area. Or Just click on the map
after activating the zoom tools.
Or Use the on-screen pan and zoom tools
12
Navigation Tools
Full Extent, Back Extent, Forward Extent These
tools are self explanatory and require only a
click directly on the tool to cause a change in
your map view. Be aware that the extent buttons
do not show previous layers that were turned on,
merely your current layers in the old extent.
Full Extent Example
13
Window Magnifier Tool
Magnifier Window Allows you to magnify a chosen
area without changing your map scale. Magnify
your area from 2 times to 10 times larger.
14
Identify Tool
The Identify Tool will give you information about
the features that are visible on your map.

• First, click the point on the map that you would
  like to identify.
• Click the arrow beside the first layer name to
  see a complete list of layers that were
  identified.

15
Identify Tool

• To view the identify results for that layer,
  click on the layer name.
• You now have the option of adding this
  information to the Results area on the Console
  where you may print the results with your map, or
  right click in the Results area and choose Print
  to print only the results.

16
Measure Tool
The measure tool allows you to measure distances
and areas and to find the coordinates of a
specific point.
To measure a distance, click on the line icon.
To measure an area, click on the polygon
icon. To find the coordinates of a point, click
on the point icon.
17
Overview Map Tool
The overview map shows you where in the state of
Connecticut your current map view is
located. Click to turn it on and Click again to
turn it off. NOTE The overview map is not
interactive and cannot be used to navigate to a
new location.
18
Find Address
This tool allows you to navigate to a specific
address or a street. Click on the tool. Then
type in a street address or just the street name,
followed by the type of roadway, i.e. Rd.,
Ave., Blvd, etc.
In this dialog box, although it offers
Intersection as an option, this is not
available. Also, beside the word Zone, type in
the town or city name. Zip codes cannot be
entered.
19

After zooming to the cluster of addresses in the
list, each represented by a red push pin, you can
hover over a pin and it will display the address.

21
Find Town

town. You must choose a town from the list
provided. You cannot find village names, borough
names, etc. For example, Kensington would not be
a choice, but Berlin would be a choice.
22
Find Town
After clicking on Find, the town will be
highlighted in your map view and the town result
will be placed in the Results section of the
Console.
Right click on the town name and choose zoom to
or pan to. This will place the entire town in
your map view.

• Your choices are
• Title your map
• Choose a size for your map
• Choose to print Identify results with your map
• Choose to print only the Identify results with no
  map

About the Layers
Drawing Order The layers draw from the bottom
up. Make sure that you do not have one polygon
layer drawn on top of another. Only the top
layer will be displayed.
Example Although both the orthos and the topos
are turned on, only the orthos will be visible
since they are on top of the topos.
27
About the Layers
Categories The layers are organized into
categories so that related data are logically
placed together. In addition, for some
categories, the layers are mutually exclusive.
That is, only one layer within a category should
be turned on at once. These categories
include Administrative Boundary Index,
Watershed, Geology and Soils, and Imagery and
Topos.
28
About the Layers
Overlapping Features For some categories, there
may be layers that have overlapping features.
For example, DEP property features are also
contained in Protected Open Space. This means
that those two layers may have some overlapping
features.
29
About the Layers

• Overlapping Features
• Examples of other categories that have
  overlapping layer features are
• Waterbody (All Waterbody and Hydrography)
• Water Resource Management (Assessed Waterbody
  2006 and 2008)
• Geology and Soils (Soils, Wetland, Farmland,
  Septic Potential, etc.)

30
Thematic Maps

• In Envirodata, Thematic Maps must be created by
  the user, unlike in ECO where Thematic Maps are
  already made for you.
• A list of suggested layers you might use to
  create thematic maps is shown on the next slide.
• You can also visit GIS Home on Inside DEP and
  choose List of Datalayers Available in DEP.
• Turn the appropriate layers on and off to create
  your customized map.
• Thematic Maps and Favorite Locations cannot be
  saved in Envirodata.
