GBRC GIS Web Training

Introduction

The GBRC web viewer service provides many layers of regional data and information, as compiled by Greater Bridgeport Regional Council or supplied by various government agencies� Reasonable efforts are made to ensure the accuracy and currency of the information con-tained in this web viewer� The web based GBRC GIS viewer is a pro-gram to view and analyze maps on the internet� The web viewer can be accessed by a link off of you town’s Municipal website or GBRC’s website (pending)�

Like paper maps, these map layers have information about location of features (e�g� property boundaries, roads, building footprints, pavements, driveways, rivers, trees, flood plains, cities, etc�)� These map layers are dynamic which means the can be updated from time to time as well as turn on/off different combination of available layers�

To use the GIS web viewer, you need a computer (PC or Mac) with a web-browser,

the Microsoft Silverlight Plug-in and a relatively fast internet connec-tion� The current version of Firefox (Mozilla) or Internet explorer works very well with this site� Chrome does not support Silverlight and thus will not support our current set of GIS viewers�

The training materials are meant to provide a overview of the viewers and the current set of GIS information� In time, additional map layers and application functionality are envisioned� Please provide any feed-back or questions to Mark Goetz, GIS Director, Greater Bridgeport Regional Council�

Abutters List / Buffering



A GIS Buffer is defined as a proximity analysis used to select fea-

tures within a specified distance from an origin feature (point or a

line or a polygon area). The output is a larger zone or region that

surrounds and encompasses the origin feature. The output of a Buf-

fer is often used to define or determine any features that are within

a specified distance of a point, line or polygon. For example, you

might use a buffer to create a circular area encompassing 250 feet

around a property defining this region as neighbors who are required

to be notified of a permitted project.

1. Select property by street address or property ID search tools. With a selected record in the results panel, click on the Buffer Feature link. This same tool can be invoked by right clicking on the selected record.

2. Enter the desired buffer distance (200) and keep Feet as the measurement units from the drop down list

OR



3. Check the Add Buffer to Markup if you want your buffer to draw on the map.

4. Click the Results for drop down window to check any map layer you want to include in your buffer analysis. To gen-erate an Abutters list, make sure Property is selected.

Note: Other layers can be selected for inclusion in the buffer analysis.

5. Click the Preview Buffer to view before you run the buffer tool to see what the Buffer will look like prior to running the analysis.

6. Click OK to run the buffer tool. The selected records will appear in the Results panel as well as the buffer shape ap-pear in the map.



7. Within the Results panel, click the Select All tab to see all properties selected by the 200 foot buffer on the map.

8. To export your result to an excel spreadsheet, click Table View and Export to CSV

9. You will be prompted to save a CSV file to you local PC

Documents folder (depending on OS). Browse to where you want to save the file and provide a useful name.

10. Click Save

Pictometry / Google / Google Street View


Pictometry / Google / Google Street View The Municipal Viewers are integrated with several external mapping resources� When one of the external mapping sources are invoked, a new browser window is opened with the external mapping resource� The two windows are two-way synchronized by the center of the map (Pictometry and Google Map) such that when you pan or zoom in one of the windows, the map or Pictometry View re-centers to the current window center location� For Google Street View, there is a one-way synchronized such that changes in Google Street View (move along street or change view rotation) updates the viewer window centering and updates the perspective indicator location and rotation�

Note: This concept works better with dual screen running

Pictometry View

1. Search property by address or property ID or simply pan and zoom to a location of interest.

2. Right click anywhere on the map and select Open Pictometry View Here. This will open another browser window.

Note: Different browsers behave differently when the Pictometry View is opened. This may open a completely separate browser window or open a tabbed window. It is desirable to have two separate browser windows open at the same time to leverage the synchronization of the GIS Viewer and the external mapping source(s).

3. Click and drag the Pictometry view to the second



screen if you are using dual screens to view both the web viewer and pictometry side by side.

4. If you are using a single screen and the Pictometry View was launched in a Tab Window, right-click on the Pictometry View Tab and Select Move to New Window. Either re-size the both the GIS Viewer win-dow and the Pictometry View window to be viewable. Another option, with Windows 7, is to left-click and hold down the left-click button on the top of Pictom-etry View browser window, then drag the mouse to the far left or far right of the monitor until an outline appears in the left or right half of the monitor then re-lease the left-click button. The browser window (or other application windows) will automatically fill one half of your monitor. Do the same with GIS Viewer in the opposite side of the monitor.

5. With the mock dual monitor configuration set, pan within the map. The Pictometry View should move the and re-center at the same location as the center of the map.

6. The navigation within the Pictometry is primarily with the Pan tool. When you pan in the Pictometry View, the map will also re-adjust

based on the center point of the Pictometry View. If your mouse has a scroll wheel, you can zoom into the image by moving the scroll wheel forward and zoom out by moving the scroll wheel backwards.



7. Click the Image Date drop down arrow to access dif-ferent imagery available. Shortly, the default imagery will be from the Spring of 2015.

8. Click the Rotate Clockwise or Counter Clockwise view property at different directions. The photos to

the right are the same location with the four different orientation views (North, East, South and West)

9. At the bottom of the Pictometry View is information regarding the Orientation (North, East, South, West), the Zoom Level (Neighborhood or Community), Type (Angled or Top View), the Photo Date and the zoom Scale.



Google / Google Street viewThe Google Maps and Google Street View are a single viewer� Google Street View is available along most public streets, not all though� If you engage the Google mapping on a location that does not include Street View imagery, a Google Map will appear in the viewer� The Street View can be invoke by dragging the Street View “Pegman” on top of a street segment (highlighted in blue) that has Street View imag-ery� Unlike the Pictometry Viewer, the synchronization is only sup-ported when the Google Viewer is in map mode� When the Google viewer is in Street View mode, re-centering the GIS map will not cause the Google Viewer to re-center�

1. Search property by address or property ID

2. Right click anywhere on the map and select Google Street View Here. For best results, click on or near a public road.

3. The Google Street View operates very similar to the Pictometry View in the sense that it will open a separate browser window. Follow the same steps in the Pictom-etry section to be able to view both the GIS Viewer and the Google Viewer windows at the same time.

4. Use the Compass to rotate imagery in both clockwise and counter clockwise directions and the arrows on the street view to move the view along the street.

Note: As you rotate and move along a street, a light blue tri-angle rotates and moves on the map indicating locations and street view perspective.

Working with Map Layers


Working with Map LayersThere are a handful ways to interact with the provided map layers. The Map Layers tab is available within the Informa-tion Panel, left of the map. There are two primary styles of layers, Operational Layers and Base Maps as well as a pre-defined grouping of Operational Layers and Base Maps called Layer Themes.

Operational Layers are broken down into individual layers and group layers (with the minus (-) and plus (+) symbols). Layers are turned on by clicking on an open check box and turned off by clicking on a checked check box. Group layers can be ex-panded to show all of the layers within the group by clicking a group layer with the minus (-) symbol in front of the name. Individual layers may have scale dependencies whereby the layer is designed to become visible above and/or below de-fined map scales. A layer that is currently able to be visible has a black font color and a layer that is not currently able to be visible has a green font color.

Base Maps are a single map layer that may contain several map layers but behaves as a single layer. These can be turned on and off in the Map Layers tab or the Base Map / Layer Theme Menu.

Layer Themes are predefined groupings of Operational layers and Base Maps that provide quick access to commonly needed groupings of layers and Base Maps. When a Layer Theme is selected, only those predefined layers are available in the Map Layers tab. These are changed in the Layer Theme control at

Layer Transparency

Working with Map Layers


the top of the Map Layers tab as well as within the Base Map / Layer Theme Menu.

Certain layers and group layers also have the ability to have the layer transparency to be adjusted by the end user. This allows underlying layers to be visible through the overlying layer.

1. Practice adjusting layer combinations.

2. Using the Base Map / Layer Themes menu, change the Base Map Topographic to Imagery (Aerial Photo).

3. Using the Base Map / Layer Themes menu, change the Layer Theme to any of the available categories.

4. Within the Map Layers tab, turn on or off individual layers and group layers.

5. Change the map scale and see the resulting changes in available layer visibility.

6. Turn on both the Topographic and Imagery Base Maps. Alter the top most Base Map transparency by selecting the transparency slider and moving it to the left and right to see the transparency effects.

Advanced Functions


Creating Markup on MapThe viewer provides the end user with the ability to add vari-ous markup to the map. This markup can be various geometric shapes (points, lines, polygons, and freeform shapes) as well as text annotations. The markups can be different styles, borders, colors and transparencies depending on the markup type. These will appear on generated PDF maps as well as exported images. These even can be extracted as GIS shapefiles.

Search and zoom in to the section/area you wish to mark up

1. Click I Want to menu drop down arrow and select Draw on the Map or open the advance toolbar, then select Tasks and chose any of the drawing tools to activate the markup options include point, line, ellipse, polygon, triangle, text, freehand, circle, rectangle and arrow.

2. Select one of the markup types, then change the drawing color, style and thickness by using the available tools as

Map Measurements

The viewer provides tools to measure distances and areas� The tools allow the units of distance and area to be specified. Both the graphic of the measurement as well as the distance or area values plus the units are placed on the map� These are added as measurements by default, or can be converted to markup� The measurements are avail-able to be printed on the a PDF printed map or exported image� The measurement tools are located on the Advanced Toolbar under the Analysis tab, but also can be accessed through the I Want To menu�

1� Click on the I Want to menu then click on Measure distance� Begin with a single click at the desired starting point� A measured line can have multiple segments which will have a cumulative dis-

tance within the Measurement Info box in the Advanced Toolbar Analysis tab as well as labels in the map for each segment�

Advanced Functions


2� Measure area is only available through the Advanced Toolbar� The perimeter and area are calculated when measuring area� To mea-sure an area get to the Analysis tab of the Advanced Toolbar� Click

on the Area tool� Start the area measurement with a single left-click on the desired starting point� Additional left-clicks will add to the measurement polygon� Segment distances will be labeled on the map as the measurement progresses and the perimeter and area added to within the Measure Info boxes on the Analysis

tab� To stop the measurement, double click on the desired end location� Please note that the system will automatically connect the starting point and the end point so there is no need to put the end point on top of the starting point� The Perimeter and Area units can be changed at any time and the labels on the map will reflect those changes in units.
