AGENDA BILL NO. 6 3. O £. , Dept. Hd.
DATE: March 18, 1980 Cty. Atty.
DEPARTMENT: PLANNING Cty. Mgr.
SUBJECT:
PURCHASE OF AERIAL PHOTOS AND BASE MAP SYSTEM
STATEMENT OF THE MATTER
The various departments within the City of Carlsbad Government are
constantly faced with a number of significant and complex projects.
In order to evaluate and process these projects, the staff needs
current, complete information including an accurate base map system.
Photo Geodetic Corporation is offering the aerial photos and a base
map system of the City of Carlsbad for $6,745. Adequate funds now
exist in the professional services categories of the Planning and
Engineering budgets. Planning will pay $4,745; Engineering will
contribute $2,000. The price is substantially lower because Photo
Geodetic, while on a survey flight for another contractor, took
the photographs on speculation and therefore does not have to ;:pay
for another flight or survey crew.

Resolution No. £> / 2J_
RECOMMENDATION
Staff is recommending that the City of Carlsbad authorize by reso-
lution the purchase of an aerial photo base map system from the Photo
Geodetic Corporation for $6,745.00.
Council Action:
3-18-80 Council adopted Resolution 6121, authorizing the purchase of an aerial photo
and base map system.
MEMORANDUM
DATE: February 26, 1980
TO: Frank Aleshire, City Manager
FROM: James Hagaman, Planning Director
SUBJECT: PURCHASE OF AERIAL PHOTO AND BASE MAP SYSTEM
A set of aerial photos of the Carlsbad coastal zone were
included as part of a contract between the Coastal Commission
and the consulting firm of PRC Toups for the Carlsbad Local
Coastal Plan. The firm, as speculation, took additional
photos of the entire city and has offered them as a base map
system. If the City Council agrees to purchase the aerial
photos and base map system, a bid process for selection is
not necessary. Photo Geodetic will be simply supplying a
set of ortho photo maps and image sheets from their existing
stock of photographs. Therefore, a resolution authorizing
the purchase is sufficient.
For $6,745 the firm, Photo Geodetic Corporation will supply
the following items:
1) Orthophoto Contour Maps
Reproducible 24"x36" maps made from a perfectly scaled
aerial photographs with the contour lines superimposed. The
scale is 1" = 400' with 20' contour lines and 10' supplemental
lines on flatter areas. ($5,520)
2) Orthophoto Image Sheets
Reproducible, scaled 24"x36" photographs (1" = 400')
with no contour lines; these sheets would be needed as a
clear map for such uses as property line overlays. ($600)
3) Control Points
Survey points used to control size and elevation in
photographs. ($400)
4) Air Photos
Reproducible 9"x9" air photos; copies of the original
prints with a scale of 1" = 3000'. ($225)
As stated before the total cost would be $6,745. The Engineering
Department has agreed to contribute $2,000; the Planning
Department's share would be $4,745. Adequate funds exist on
both departments professional services categories.
Other firms were asked to quote rough estimates over the
phone of the work. The estimates ranged between $15,000
and $30,000. These estimates were higher because field
crews and flight time would have to be paid for; Photo
Geodetic has already taken the aerial photographs with the
assistance of a field crew for another project.
Currently, the city uses a cadastral map system which is
based on property lines and a map series based on aerial
photographs and addresses. Both map systems are outdated.
The proposed maps are based on aerial photography of the
topography of the city and will not become as dated as other
systems.
A current base map system is needed for the following reasons:
1) For accurate reports, maps, and memos to City Council
and other decision makers.
2) For an aid in the preparation of studies and in the
evaluation of projects;
3) To provide maps for the public and that are clearly
legible and understood.
For these reasons and due to the unique and substantially
lower price, staff is recommending that the City Council
authorize the purchase of the orthphoto contour maps,
orthophoto image sheets, control points, and air photos
for $6,745 from Photo Geodetic Corporation.
