How do I connect to the CT ECO map services in ArcMap?

There are two ways to connect ArcMap 9.3.1 (or more recent) to the available ArcGIS Server map services.

Method 1 - Open the map service directly from the CT ECO Map Services page

  1. From the Map Services page, click on the name of the map service you want to add (e.g. Habitat) and then click on the word "ArcMap" where it says Open in ArcMap to the right of the thumbnail.
  2.  

    Open in ArcMap

     

  3. In the File Download window that opens, click the Open button to automatically add the map service to ArcMap. If not open, ArcMap will launch with the map service connected. Use this method repeatedly to add more than one map service to ArcMap.
  4.  

    Add map service to ArcMap

Method 2 - Make a connection directly to the appropriate CT ECO ArcGIS Server and choose from the available map services.

  • http://www.ctecoapp2.uconn.edu/arcgis/services - ArcGIS Server URL for base map and other thematic map services.
  • http://www.ctecoapp3.uconn.edu/arcgis/services - ArcGIS Server URL for othophotography.
  1. In ArcMap, click the Add Data button. From the Look in text box at the top, click the down arrow and choose GIS Servers.
  2.  

    Add ArcGIS Server dialog box 1

     

  3. In the list, click on Add ArcGIS Server. The CT ECO Map Services use ESRI ArcGIS Server 9.3.1 map services.

  7. Double click on arcgis on ctecoapp2.uconn.edu. As shown below, open the maps folder that contains the thematic map services.

    List of map services

     

    Alternatively, if you connected to http://www.ctecoapp3.uconn.edu/arcgis/services, an images folder contains image services of orthophotography.

    List of image datasets

     

    Choose the map service you want and press the Add button. Below is an example of ArcMap connected to the maps/Base_Map map service. As show below, once a map service like Base_Map is added, you might need to turn on its visibility checkbox in order to see the information. Note, in addition to turning on the map service’s visibility checkbox, depending on the map service, you may need to turn on a layer within the map service and zoom in to a more detailed scale in order to display information.

     

    List of Base Map Layers

    The data is already symbolized for you in these map services. You can view the data and turn individual layers on and off, but you cannot edit the data, nor can you open an attribute table for any of the datalayers. You can, however, use the Identify tool and retrieve feature database information in this way.

I am using ArcMap 9.2. Why am I unable to see the list of services in the images folder?

ArcGIS Map services in the images folder are only compatible with ArcGIS Desktop 9.3 or greater, however with ArcGIS 9.2 you can use a WMS connection to access these (orthophoto) map services in the images folder. The ArcGIS Map services in the maps folders are compatible with ArcGIS Desktop 9.2 or greater. ArcGIS Desktop includes ArcView, ArcEditor and ArcInfo software.

  1. With ArcGIS 9.2, use the following URLs to access the individual orthophoto WMS services.

How do I connect to the CT ECO WMS map services in AutoCAD Civil 3D 2010?

Follow these instructions to connect an AutoCAD Civil 3D 2010 session to the CT ECO WMS services. Similar approaches can be achieved through older versions of AutoCAD Civil 3D and AutoCAD Map as well as other CAD software such as Microstation. Additional instructions are available online from Autodesk (for AutoCAD software) or Bentley (for MicroStation software).

Enable the Geospatial Workspace. (There are multiple avenues to invoke and access AutoCAD tools. The following is just one way to access tools to pull in WMS services.)

  1. Depending on the initial workspace, the User Interface dialog box needs to be invoked. This can simply be access by typing CUI or going through the Manage ribbon on the Default Civil 3D Default workspace then clicking on User Interface tool as shown below:
  2.  

    Autocad Example

     

  3. Once the User Interface dialog appears right-click on Task- or Tool-based Geospatial under the Workspaces tree, then click on Set Current.  Click Apply and then OK to switch to one of the geospatial workspaces.
  4.  

  5. Set up the Map.  In order to pull in the CT ECO WMS services, a Coordinate System needs to be defined for your AutoCAD session.  The CT ECO WMS services are utilizing the Connecticut State Plane NAD 83 coordinate system.  Click on the Map Setup ribbon then the Assign tool. 
  6.  

    Autocad Example

     

  7. Once the Assign Global Coordinate System dialog box appears, click on the Select Coordinate System button. 
  8.  

  9. On the Select Global Coordinate System dialog box there are two options for selecting Connecticut State Plane NAD 83 (Feet) coordinate system, click on the Category: pull-down list or type the appropriate starting code in the Search box then click Find.  If you utilize the Category pull-down list, you click on the pull-down list then type U Eight (8) times to get to USA, Connecticut category.  If you utilize the Search tool, just type CT to get to the USA, Connecticut category.  Once you have the USA, Connecticut category select CT83F then click OK.  Once back to the Assign Global Coordinate System dialog box, click OK to assign Connecticut State Plane NAD 83 (Feet) as the coordinate system.
  10.  

    Autocad Example

     

  11. Once you have selected the coordinate system for your drawing, you can now connect to the CT ECO WMS services.  With the Map Setup ribbon active, click on the Connect tool.  This will bring up the Data Connections dialog box.  Please note, there are many different Geospatial Data Connections available through this dialog, such as ArcSDE and Shapefiles (SHP) and this dialog provides access to those difference data types through the same dialog.
  12.  

    x

     

  13. At this dialog a web-based connection string (URL to a CT ECO WMS map service) is needed to connect.

    Lookup the URL of the map service you want to use in the CT ECO WMS map service list.

    For this example, we will connect to the 2004 State of Connecticut Black and White orthophotography (Ortho_2004).  It is good practice to type in a useful Connection name in the Data Connection dialog, there may be instances whereby multiple WMS maps services are utilized in a drawing and you want to be able to turn these WMS layers off or on.  After typing in a useful name into the Connection Name box, copy and paste the URL of the specific WMS service you want to add to your drawing into the Server name or URL box.The URL for the 2004 State of Connecticut Black and White orthophotography is:

    http://www.ctecoapp3.uconn.edu/arcgis/services/images/ortho_2004/ImageServer/WMSServer?
  14.  

    Autocad Example

     

  15. Click the Connect button.
  16.  

  17. You will be prompted for a User Name and Password.  Leave these blank, but check the Remember password checkbox so that when you re-open your drawing you will not be prompted to re-enter you <blank> password.  This makes it useful when you are connecting to a different but password-protected  WMS server.  Click on the Login button. 
  18.  

    Autocad Example

     

  19. Once you are connected, there are several options on how let AutoCAD handle the WMS feed.  The properties that the end user should change under the WMS_Schema property section are Image Format and Server CS Code (Server Coordinate System). What seems to work for the CT ECO WMS services is a jpeg image format and EPSG:2234 (Connecticut State Plane NAD 83 Feet).  Other combinations will not work properly for the Orthophoto WMS services.  This may be different for other WMS services provided by CT ECO or other providers.  Once these are set properly, click on the Add to Map button below the WMS_Schema property section.  Then close the dialog with the X in the top right corner of the dialog box.
  20.  

    Autocad Example

     

  21. The resulting map will resemble the example below when starting from a blank drawing.  You will be able to zoom in, zoom out and pan throughout the drawing and the background 2004 Connecticut Black and White orthophotography will refresh after each release of the mouse.
  22.  

    Autocad Example

     

    Go to the CT ECO Map Services section for CT ECO Data Guides and/or GIS metadata that document data included in each CT ECO map service. For example, the 2004 Orthophotography Data Guide includes a description, purpose, use limitations, and list of originators.

What type of orthophotography is available for Connecticut from CT ECO?

Orthophotography available from CT ECO covers the entire state or a particular region in Connectiut, depending on the type and year of the aerial survey. For example, statewide orthophotography is available for 1990, 2004, 2006, 2008, and 2011 in either black and white, full color, or infrared, and either taken during the summer or early spring, depending on the year. Orthophotography for the summer of 2004, 2005, and 2010 in both full color and infrared is available for towns along the Connecticut coastline and Connecticut River. Orthophotography for the Greater Bridgeport, Hartford, and New Haven urban area is available for the spring of 2008. Orthophotograhy for towns covered by the Capitol Region and Plainville is available for the spring of 2009. Photography taken during the summer is generaly referred to as "leaf on" orthophotography, and photography taken during the early spring is generally referred to as "leaf off" photography. Leaf off photography is captured immediately after the snow cover melts and before stream levels rise and leaves blossom on the trees. It is ideal for observing features on the ground surface in developed, open or wooded areas. The leaves on trees and shrubs that would normally obstruct the view from above during the Summer are largely absent in the early spring, allowing for the observation of features such as stone walls, roads, and structures in wooded areas, lawns and yards.

Refer to Connecticut Digital Orthophotography for a list and brief description of orthophotography available from CT ECO.
