Zoom to Longitude / Latitude
list will zoom the map to various areas in the County. Pick the desired area from the list and wait a moment while the map re-draws.
tool from the tool bar and enter the longitude and latitude of the location that you wish to center the map on. Longitude and latitude may be entered in various ways:
|| negative sign before longitude is not required
|Degrees Minutes Seconds
|| 110 45 42.89
|| 43 28 48
|| degrees minutes and seconds separated by a single space
seconds can have decimal fractions
|Degrees Decimal Minutes
|| 110 45.4592
|| 43 28.9517
|| degrees and minutes separated by a single space
minutes can have decimal fractions
The longitude and latitude that you enter must
be on either the NAD83 or WGS84 datum (generally used in GPS and newer maps)
and not NAD27 which was used on the original USGS topo maps. Entering a NAD27 longitude / latitude
could cause the map position to be off by several hundred feet.
Getting Information from the map
tool from the tool bar and then either:
- Click on the map
- Hold the mouse key down and drag a box over the area on interest to select multiple lots or parcels
Basic information will be displayed with links to more detailed data.
Finding things on the map
Searches are initiated in the Search
tab. The MapServer can find properties by:
- Street address
- Legal description (Subdivision and Lot, or Township, Range, Section)
- Property owner name
- Parcel ID Number (PIDN) or Tax Roll Account number
Searches can be entered either as free-form text in the search box,
or by category by clicking the "advanced search" link.
- Search by Street Address
- You may enter a street address number (not required), and a street name. Generally it
is best to leave off the "Road", "Street", "Ave", etc.
In the free-form text search, a full street name is required. In the advanced search,
a partial street name works (this is handy if you are not sure of the spelling of a
street name). You will be presented with a list of addresses matching your search.
From the list you may pick one or more addresses to map.
- Search by Legal Description
- You can enter a subdivision lot number (optional) and a subdivision name.
You will be presented with a list of matching lots. From the list you can
pick one or more lots to be mapped.
- Township, Range, Section searches generally take the form of: T20N R90W SEC 4.
The text search may return more results than the "advanced search".
- Search by Owner
- You may search by property owner name. A list of matching property owner names will
be presented, from which you may select a property to be mapped.
- The advanced search allows partial names, for example "Green" will find "Green, Greenwood, Greenberg", etc.
- Search by Parcel Number
- PIDN. A partial PIDN may be entered to find all parcels in given a Township, Range, Section
- Tax Roll Account Numbers must begin with a letter followed by 7 digits
(all padding zeros must be included) e.g. R0001234
After you have used the "Map It" button to highlight a selection from any
of the above searches, the selection will remain highlighted until another searches
is run, or until it is "Unselected" by clicking the
There is too much information to show all of it at the same time,
so the map is organized in "layers" of data. A list of available
layers is displayed to the right of the map. There are labels, foreground layers, and
background layers. The foreground layers are lines and hatches, which are more or
less transparent, so you can turn on as many as you want. The background layers are opaque,
so it is only possible to turn on one background at a time.
Many of the layers are scale dependent, especially the labels. This means that even if a layer
is turned on it may not be displayed if the scale is too large or small (if you are zoomed
in too far, or zoomed out too far). For example, street address numbers simply can't be read
at scales smaller than 1:10,000 so they are not displayed. If you do not see a layer
that you have turned on, try zooming in a bit.
Measuring Distances, Bearings and Areas
Approximate distances and bearings may be scaled from a map using the "Ruler" tool
Select the tool, and then single-click a starting point on the map. As the mouse
is moved over the map a red "rubber band" is drawn, and the distance is
show near the top of the screen. Additional single clicks on the map allow you to measure
distances along a route or around a polygon.
Both a running total distance and an individual segment distance are displayed. Double click
within the map window to terminate a distance sequence.
Approximate areas may be calculated by using the "Area" tool
Clicking points on the map will draw a polygon. Double click to finish the polygon,
and the total area will be displayed on the left side of the bottom status bar.
Printing, Linking and Saving maps
: The "Print Layout" tab puts the current map view into a printer friendly layout.
You may set the scale in either feet per inch or miles per inch. The initial scale values will approximately match the current map view.
Click the appropriate link for your desired paper size and orientation.
- Click the scale bar in the page layout to reset scale, page size or orientation
- Set margins in your browser and/or printer setup
- Turn off "Shrink to fit" options to get accurate scale when printed.
- The map can be dragged into other programs or documents.
- The map can be saved to your computer by right clicking on it.
Linking: To bookmark or email a particular map view,
click on "link". This will copy
a new URL into your browser's address bar that defines the layers and location that
you are looking at. You can bookmark (Add to Favorites) the address to return to the
view at a later time, or you can copy the URL into an email. Be sure to get the whole
URL, it is quite long! If you don't like such a long URL, you can use a free service
of tinyurl.com to shorten it.
Saving to your computer: Saving a link is usually preferable to saving
the image, but if you do need to save the image, printing to PDF from the Print Layout tab
is usually the most reliable method of saving a copy of a map view to your own computer.
The Print Layout tab can also be used to save the map as a GIF or JPEG image. Right click on the map and select "Save Picture As" or
"Save Image As". The map in the Print Layout tab is a high dot-per-inch resolution than the same map in the Map tab.
Adjoiner Buffer List
tool creates a list of all parcels within a specified radius of a parcel(s) and also
shows all of the parcels within the radius on the map. This can be used to create an
adjoiner notification list.
- Before the buffer tool can be used, one or more parcels must be selected (highlighted).
Parcels are selected by using the Map It link on either the Info Tool window or the
query Results List page.
- With a parcel(s) selected, click the buffer tool. You will be prompted to specify a buffer
radius. All parcels within your specified radius will be selected even if only a very
small part of the parcel(s) lie within your buffer.
- A mailing address list suitable for use in a Mail Merge is created, and the map window is updated.
- The buffer radius is shown in blue.
- The parcels within the buffer radius are outlined in orange.
