A
geo-referenced DOQ is a computer-generated image of an
aerial photograph in which the image displacement caused by
terrain relief and camera tilt has been removed. The DOQ
combines the image characteristics of the original
photograph with the georeferenced qualities of a map. This
one is a composite of two photos. It is shown here mainly
to reference Kala Point properties. Compare to
2003 color photo.
Contour Map
Same
data as in Shaded Relief Map (top of page) with 3-meter
contour intervals.
Aspect Map
Same
data as in Shaded Relief Map at top of page.
Black is northerly, blue is westerly, white is southerly,
and red is easterly.
Aspect maps are used in viewshed analysis. For example, if
you were standing anywhere in the blue area, you would have
a potential view of the water and Cascade Mountains to the
east.
Note:
These maps were processed from raw data. For the average
user, one of the richest sources of easy-access information
and mapping for Kala Pointers is the Jefferson County GIS
(Geographic Information System). It is not only a gold mine
for parcel-specific details, but also for county-wide data
and maps. Very few counties of this size have such a
high-caliber GIS department. Be sure to look at both the
'Parcel Map' and 'Critical Areas' pages because each
contains unique information and layers absent in the
other: Jefferson County Interactive
