The Layer Visibility Component
This component allows the user to view several layers at once, as well as change the transparency of each layer. As you check the boxes to turn on or off the layers, you will become familiar with how they look and can then customize the Viewer to your needs when you open it.
Please note that some layers are only visible as you zoom in. Sometimes you have to zoom out in order to select or deselect layers.
The layers that open by default are Imagery Background, Labels, Roads and Current FEMA Data.
To go to another Component, click on the title.
The Search Parcels/TRS Component
This component allows the user to search for parcels in several different ways: Owner Name, Address, APN (Assessor’s Parcel Number) and Township-Range-Section.
The default search is by Address. Click on the Select Search Type dropdown to choose another way to search.
Click this box to type in your search criteria. You must have a complete APN or Township Range and Section to use either of those search types. However, when using the name or address search types, you can use a partial name or address.
For example, if you only have the street number, your results would look like this.
If you do not see the record you are searching for in the list of records displayed, often there are more records available below what is able to be seen in the small window.
To locate the additional search results, place your cursor over the search results displayed and use the scroll feature of your mouse to scroll down to the record you are looking for. If you do not have a scroll feature on your mouse, you can left click anywhere in the records showing and use the down arrow key on your keyboard.
When you have found the desired record, left click anywhere in the row of that record and the Viewer will Zoom to that parcel.
