GIS - F.A.Q.

Screen Resolution

The Glastonbury GIS has been designed to work best with monitors that have 1024x768 pixel resolution or higher. Lower resolution monitors will not be able to display the entire window, which means that the user will need to scroll from top to bottom or from left to right.

If you find that you cannot see the entire map window, you may be able to simply increase the resolution of your monitor. To do so, take the following steps:

· Click on your “Start” button, click the Settings option, and then click the Control Panel option.

· When the Control Panel window opens, double-click on the Display icon

· Click on the Settings tab

· Where it says “Screen Resolution”, note the existing resolution so you can restore it to the original setting if desired later.

· Where it says “Screen Resolution”, drag the bar over to the right until the screen resolution is 1024x768 (or greater). If you have dragged the bar as far as it will go to the right, and the resolution is still less than 1024x768, your video card does not

support the resolution needed to make the scrolling disappear.

· Click the “Apply” button. The screen may temporarily turn black.

· You may get a message saying “Your desktop has been reconfigured. Do you want to keep these settings?” If you get this message, click “Yes”

· Click the “OK” button to close the Display window.

· Close the Control Panel window.

Preferred Internet Browser

The Glastonbury GIS has been designed to work best with Microsoft’s Internet Explorer 5.5 or higher.

The Glastonbury GIS also works with Mozilla and Firefox browsers, but some functionality is disabled when

using these browsers.

Pop-Up Windows

There are some features in the Glastonbury GIS that generate popup windows, so some configuration may be needed to allow popup windows from this site. Since there are many products that block popup windows, this document does not explain how to configure all of the products. However, the most popular popup blockers display a message when a popup has been blocked, and you can usually click on the message to allow the popups.

Additional Software

The Glastonbury GIS generates Adobe Acrobat (PDF) files when generating printable maps, property reports, or mailing labels. To view these PDF files, you will need to have a minimum of Adobe Acrobat Reader 5.0. The latest version of Adobe Acrobat Reader can be freely downloaded from: http://www.adobe.com/products/acrobat/readstep2.html

Login Requirements

The Glastonbury GIS does not require logins for general access mapping services that are displayed on the splash page. Logins are required for select specialized services for internal use. Logins and passwords are assigned on a need basis.

Service Selection

The Glastonbury GIS will have several services for the general public and staff. These services are customized to display different items at different scales. Explanation as follows:

“Glastonbury” Service has all available layers available for display and is the base map for all other mapping services.

“Assessment” Service has been culled of layers to display only those layers pertaining to the Assessment Office.

FYI – Look at the legends for each service, note that not all layers are available in the Assessment Service.

Mapping Data

The Glastonbury GIS has data from several sources, and below is a brief description of there source and age.

All Planimetric and Contour Data are from the aerial photometric flight done in May of 1998. The Planimetric data includes Buildings, Roads, Brooks, Utility Poles, Trees, and other surface features including the contour data. This data has not been updated since the original aerial flight.

All Cadastral Data or Parcel Data is updated on an ongoing basis, and includes easements for Town Utilities and Conservation Areas.

Town Utility Data ie., Storm and Sanitary Sewer is from 1997 and is in the process of being brought up to date.

Aerial Images

The Glastonbury GIS has Aerial Images from two sources, and below is a brief description of there source and age.

Town wide color images are from the 1998 aerial flight and have a higher resolution and greater accuracy. These images where used as the base for the planimetric and contour data shown on the GIS web site.

The Black and White images are from a 2004 aerial flight that was created by the state of Connecticut and put into the public domain. These images are for reference use only, and are not to be construed as accurate.
