PHOTOGRAMMETRIC ENGINEERING & REMOTE SENSING
a perspective photograph by removing those displace-
ments of points caused by tilt, topographic relief and
central projection (perspective). Sometimes called an
orthophoto map, an orthophoto is georeferenced and is
geometrically corrected such that the scale is uniform:
the photo has the same lack of distortion as a map and
can be used to measure distances, locations, angles, and
the relationships between objects on the earth, to within
a specified accuracy. Accuracy depends on process and
project design parameters.
•
Ownership:
Is the state or fact of exclusive rights and
control over property, which may be an object, land/real
estate or intellectual property.
•
Product Sales
: Sale of standardized products, usually
according to an established pricing structure and often
offered under license agreements for specific uses; spec-
ifications are established by the provider, though the
purchaser may be able to choose from several options.
Refer to Table 1 for a detailed definition of products.
•
Professional Services
: Projects that require spe-
cialized knowledge and skill, require independent judg-
ment, and require a level of professional expertise and
ethical conduct to ensure that the work meets the best
interests of the client and public. Refer to Table 1 for a
detailed definition of professional services.
•
Product Support
: Provider services such as in-
stallation, configuration, data maintenance, data
reformatting and training to support a product. Also
include delivery services such as Provider Hosted,
Software as a Service (SaaS) or Data as a Service
(DaaS). Service Level Agreements, fee for service or
annual maintenance fees typically apply
•
Published Price List
: the providers’ publicly pub-
lished retail sales price for a product offered to the
market. Retailers, wholesalers, or resellers may dis-
count form this list at their discretion.
•
Qualifications Based Selection
: Qualifications
Based Selection (QBS) is an objective and competitive
process used by a procuring entity (owner) who evalu-
ates and selects the most qualified firm to procure ser-
vices based on a professionals’ qualifications in relation
to the work required, found in Federal law (40 USC
1101), the American Bar Association Model Procure-
ment Code for State and Local Government, numerous
state laws and referenced in the FAR, Part 36.
•
Remote Sensing:
Gathering and processing informa-
tion about an object without direct physical contact.
•
Rectified Imagery:
Imagery that has been trans-
formed and processed to be projected onto a common
surface. Historically the geospatial term of rectification
was defined as the process of correcting a photograph
for displacement due to camera tilt only. Currently, the
term is often used more generally to apply to a wider ar-
ray of transformation processes used to project imagery
onto a common coordinate system. “Ortho-rectified” im-
agery is corrected for camera tilt, distortion and terrain
relief. “Rectified imagery” is a more general term and
implies that a less robust transformation, which typical-
ly would not directly correct for terrain relief.
•
Referential Mapping
: Mapping that does not rep-
resent authoritative locations or survey data. This
mapping is for reference purposes only and not for the
purpose of determining reliable locations to be used as
the basis for making measurements or other determina-
tions. Locations of features are approximate (i.e., rela-
tive) and are not expected to comply with a specific posi-
tional accuracy requirement. Refer to NCEES materials
cited in the references section for further clarification
and examples for applying this term.
•
Specification:
(often abbreviated as
spec
) is an ex-
plicit set of requirements to be satisfied by a material,
product, or service. Should a material, product or ser-
vice fail to meet one or more of the applicable specifica-
tions, it may be referred to as being
out of specification
;
Specs are a type of technical standard.
•
Standardization:
is the process of developing and im-
plementing technical standards.
•
Subscription Service:
This business model is where
a customer must pay a subscription price to have access
to the product or support service for a defined period of
time. The content or service provider typically delivers
to a set specification with support services to the clients’
use.
•
Technical Products
: Standardized products for spe-
cific tasks that do not require independent professional
judgment and where the client is responsible for ensur-
ing that outcome best meet customer and public inter-
ests.
•
Technical Services:
Standardized services for spe-
cific tasks that do not require independent professional
judgment, and where the client is responsible for ensur-
ing that the scope of work and outcome best meet client
and public interests.
•
Value Added Service:
Services available at little or
no cost, to promote and support their primary product.
These support services can be delivered by the product
provider, reseller, or third-party authorized agent for
the product.
•
Warranty:
In business and legal transactions, a war-
ranty is an assurance by one party to the other party
that specific facts or conditions are true or will happen;
the other party is permitted to rely on that assurance
and seek some type of remedy if it is not true or followed.
