The Legend
Each entry in bold is called a

Attributes that will display when
active.
To activate a Feature, place a check
in the box.
To view the Attributes, click on the
Feature name.
Example: With the “Public
Building/Locations” Feature turned
on, the Attributes listed are what
appears on the map.
13
The Legend
Zoom in to the map if a Feature you checked
is not visible. Some Features are scale
dependent and require you to zoom in.
Use
or
, in the toolbar, to zoom in.
Please Proceed for an example…

, but not displayed…

to an area of the map.

16
Map Topics
The first map displayed when you enter the
site is “GIS Base Map” . You will notice a
black dot next to it showing that it is
currently the active map.
Each Map Topic in bold contains related
interactive maps.
Note: The topic “Sheriff” is
not accessible by the public.
Notice in the legend how the Features
change depending on the Map Topic you
are viewing.
The Query
capabilities also change as
you view different Map Topics.
17
Query
A Query
is a question or
inquiry. It’s a
way to search
through data.
Notice the
different topics
listed across the
top of the Query
box.
Each topic
contains different
ways to Query
that information.
Examples on the
following slides…
18
Query Examples
A Query for the Address “110 Sycamore St”, displays only one result,
Therefore the map is automatically generated for that location…
19
Query Examples
However, if you remove the “Street Suffix” from your search criteria,
multiple results appear.
Click the pin
next to the result you want and a map will generate.
20
Query Examples
When searching for an Owner of a parcel, it is recommended that you minimize the
information you enter.
A Query with the last name “Smith” and first name “Mike” doesn’t return any results.
When the search is minimized to last name “Smith” and first name “M”, many results
return.
21
Review of the Query Function
If only one Query result is found, the map will automatically redraw
to display the result.
If more then one result is found then select the result you want to
display by clicking on the pin
.
If your Query returns no results, try limiting the information you
entered. In turn this will broaden your search.
You can Export your Query results to an Excel Spreadsheet by Right
clicking your mouse on the blue bar of the results and select “Export
to Excel”. (This is an Internet Explorer function, not a tool of
GISWeb.)
22
Export to Excel
To Save your Queried results, Right click on the blue bar above
your search results. You will be given the option to “Export to Excel”.
(This is an Internet Explorer option. If you do not have this option under the
right mouse click, visit the Microsoft website to find out how to install this
option.)
Right Click
Here…

landscape.)
24
Hidden Tools
Using your mouse, right click on the
map for additional tools…
The “Magnify” tool displays the map in a
magnified window allowing you to read
small text or decipher busy areas of the
map.
“Text Magnification” will enlarge text that
is hard to read.
The “Redline” tools are used to draw and
make temporary notes on the map. The
following slides will further explain the
Redline tool.
25
Redline Tools
Redline allows you to place text or lines on
a map.
First, adjust Text Size and Line Size: Right
click on the map, highlight Redline and
choose Text Size or Line Size.
Right Click again and choose Text to start
typing, or select the type of Line you’d like

be saved as a CGM file.
