The Legend • Each entry in bold is called a Feature. Each Feature has a list of 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.
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…
The Legend • “Aerials” is turned on , but not displayed…
The Legend Zoom by rectangle to an area of the map. The aerials are now visible.
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. • 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. Note: The topic “Sheriff” is not accessible by the public.
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…
Query Examples A Query for the Address “110 Sycamore St”, displays only one result, Therefore the map is automatically generated for that location…
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.
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.
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.)
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…
Print a Map • Most maps Print better in the Landscape Orientation. • The “Color” option is automatically set to Black & White. You can change to Full Color. • Legend Entries allows you to choose the information needed in the legend. If you leave an entry unchecked it will still be visible on the map, just not noted in the legend. • Select “Preview”>File>Print (you may need to change your printer properties to print landscape.) Print Options
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.
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 to add: • Callout • Simple line • Circle • Compound line • Redlines are not saved on a map and therefore will not print. To get around this, Right Click go to “Save…” and the map will be saved as a CGM file.
Hotspots • Many features on the map are Hotspots. • Some Examples Are: • Annexations • Schools • Parks • Public Buildings • When selected on the map, either an additional Attribute box or picture will appear.
