Introduction
|
Welcome to the
Jefferson County Mapping system. The application was produced
collaboratively by the County GIS dept. and a consortium of other
Oregon County / City agencies (especially Polk, Crook, and Lincoln
Counties and the City of Corvallis). Custom programming
was completed by Houston Engineering. GeoMoose is used
for the mapping interface which is an open source application
based on mapserver and Open Layers (other JavaScript libraries
are also referenced). Spatial and tabular data is stored
in a PostGIS database |
Browser
|
The application
has been developed to be compatible with all modern internet
browsers including Internet Explorer, FireFox, Chrome and
Safari. |
PC (RAM)
|
We recommend you
have at least 256MB of RAM on your computer.
|
Internet
Connection
|
To get the best
out of our mapping system you need to have as fast an internet
connection as possible. We recommend DSL, Cable or higher
internet connectivity. |
Pop-ups
|
Like many other
web-based applications users will be prompted to allow pop-ups
for the site. If you are using versions of Internet
Explorer you will be automatically prompted to either
temporarily or permanently allow pop-ups from this site.
Alternatively go to Tools, Internet
Options, select the Privacy tab and
under Pop-up Blocker click Settings. Next,
type http://maps.co.Jefferson.or.us/
and press Add to make sure pop-ups
are allowed for this site.
Yahoo and Google
toolbars installed in Internet Explorer also contain
pop-up blockers. If you allow pop-ups in Internet Explorer
these toolbars will continue to
block pop-ups by default. For instructions on disabling them
visit http://www.disasterhelp.net/popupblockers/ |
Functionality
|
There are
multiple versions of the County mappings system running,
consequently not all of the tools described in this document
will be available to all users. Tools only
available in the expanded subscription and staff services are
noted in red. Any questions? Contact the GIS dept. Tel:
541-416-3930 Email: crookgis@co.crook.or.us

Map Accuracy
|
Every effort has
been made to ensure the accuracy of the data provided.
Apparent positional errors between the air photo, parcels,
roads and buildings layers are due to the current DOR rural
map accuracy standards. By the end of 2011 this
difference should be improved substantially through the
cooperation of County GIS, the County Surveyor and the Dept.
of Revenue. | |
Navigation
Tools
|
The Zoom In
tool allows you to zoom into an area smaller than the area currently
visible on the map window. To zoom in to a specific area of
interest, click the zoom in button and move your cursor to
a corner of the map you wish to zoom to. Press and hold the left
mouse button and drag a rectangle around the remaining portion of
the area of interest. When you have defined the zoom-to area,
release the left mouse button. The map will zoom into the area you
designated. Alternatively you can click on the map zooming the
display into a specific location. |
|
The Zoom Out
tool allows you to zoom out to an area larger than what is currently
visible on the map window. To zoom out, click the zoom out
button, then click on the map at the spot in which you want to zoom
out from. The map will zoom out and re-center on that point.
Alternatively you can also click and drag a Zoom Out
window. |
|
The Zoom Back
tool allows you to go back to the previous extent you were
viewing. |
|
The Pan tool
allows you to re-center the map without zooming in or out. To pan,
click the pan button, then either click on the map at the
point you wish to re-center the map to, or press and hold the left
mouse button down and drag the map to the desired location and
release the left mouse button. |
|
The Parcel
Info tool allows you to click on a parcel on the map display
and obtain additional information about it. The information is
provided in the results frame to the right.
|
|
The Clear button allows
any highlighted features to be cleared and removed from the
map. This is needed after a search selects taxlots, graphics
are sketched on the map, or a line / area is
measured. |
|
The
Search Tools allows for tax lots to be found based on the following
criteria:
Maptaxlot
number
Account
Street Address
Owners Name
In addition, it allows for chosen roads
or places to be highlighted in the
map |
|
The Print tool allows
you to print the map display. You will be asked for the size
of the image and the quality. You are also able to specify a
title. |
|

are a number of sketch tools available from this drop-down
menu. Just hover over the menu and a number of options are
available to mark up the map by adding lines, points or
text.
