Next and Previous Views
After you have moved around om the map by panning and/or zooming,
the and buttons will allow you to quickly move backwards and
forward through your views.
The "JumpTo ..." drop-down list provides a means to
quickly re-orient the map to various areas in the County.
Pick the desired area from the list and wait a moment
while the map re-draws.
Zoom to Longitude / Latitude
Select the 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:
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 postion to be off by several hundred feet.

Finding things on the map
The MapServer can find properties by:
Searches can be entered either as free-form text in the search box, or in the "advanced search" by clicking the search button.
- Street address
- Legal description (Subdivision and Lot, or Township, Range, Section)
- Property owner name
- Parcel ID Number (PIDN) or Tax Roll Account number
- 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 an address 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 a single lot to be mapped.
- Township, Range, Section searches generally take the form of: T20N R90W SEC 4. The free-form text 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.
- Search by Parcel Number
- PIDNs are formatted as: 2090-04-1-00-001-00 however a partial PIDN works also
- Tax Roll Account Numbers must begin with a letter followed by 7 digits (all padding zeros must be included) e.g. R0012345
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 button.
There is too much information to show all of at one 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 to 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 and Areas
Approximate distances may be scaled from a map using the "Ruler" tool . Select the tool, and then click a starting point on the map. Subsequent clicks on the map allow you to measure distances along a route or around a polygon. Double click to terminate a distance sequence, and the total distance will be displayed on the left side of the bottom status bar.
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.
Saving & Sharing a Map View
Printing, Saving & Sharing a Map View
Printing: The "print" link places the current map view into a new browser window without the toolbars, legend, or other map elements. Use your browsers print options to print the window. Before using the "print" link, you should size your browser appropriately for landscape or portrait orientation. e.g. if you want a portrait orientation, adjust the size and shape of your browser window so that it is taller than it is wide before clicking on the "print" link.
If you would like to save a view of the map to your favorites (bookmarks) or email a view to someone, click link. This will copy information into your brower's address bar that defines the center of your map, the zoom, the layers that you have turned on, and anything that you have selected on the map. You can now use your browser's "Add to Favorites" or "Bookmark This Page" menu option to save the view.
To email a view, click link and then copy the contents of your browser's address bar into an email. Be sure to get the whole address (URL) which may be quite long. Below is an example of a long link centered on the Big Horn County Courthouse with the aerial photography layer on.
linkIf 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 window is usually the most reliable method of saving a copy of a map view to your own computer. If you do not have a PDF writer, the print window can be used to save the map as a GIF, JPG or BMP image. Right click on the map and select "Save Picture As" or "Save Image As". Your browser may not correctly identify the image type, so you may have to help it. If you have aerial photography turned on, try saving as JPG. If you do not have aerial photography on, try saving as GIF. If neither of these options work, try BMP. Also note that not all picture viewing software reads all image formats correctly - if your picture viewer says "Invalid format" or something simular, try opening the file with a different program.
Adjoiner Buffer List
The buffer 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 parcels 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.
