The following words and terms, when used in this chapter, shall
have the following meanings, unless the context clearly indicates
otherwise.
(1) Geographic information system (GIS)--A system of
computer hardware, software and procedures used to store, analyze
and display geographic data and related tabular data in a geographic
context to solve complex planning and management problems in a wide
variety of applications.
(2) Geographic dataset--Digital data which illustrates
and describes some characteristic of the earth's surface or a region
near the earth's surface. A geographic dataset employs a defined,
earth-based coordinate system which allows its use in a geographic
information system. For the purposes of this rule, geospatial shall
have the same meaning as geographic.
(3) Geographic dataset enhancement--Substantial alteration
of a geographic dataset which increases its usefulness through the
addition or modification of attribute (tabular) data fields, improvements
in spatial accuracy, or extension of geographic coverage.
(4) Geospatial metadata--A description of the characteristics
of a geographic dataset, recorded in a standard format. Characteristics
include data content, quality, purpose, condition, format, spatial
coordinate system, availability, etc. The Federal Geographic Data
Committee has defined a formal content standard for digital geospatial
metadata for use by federal agencies.
(5) GIS map product--A geographic representation, in
paper or electronic format, displaying features from one or more geographic
datasets. Small scale images that are clearly intended only for graphic
illustration within a larger publication are not considered to be
GIS map products.
(6) High priority imagery and datasets (HPIDS)--HPIDS
are geographic datasets identified by the state Geographic Information
Officer as high priority for acquisition or enhancement, developed
or acquired by state agencies, and intended for sharing and integration
into a single statewide compilation.
(7) State Geographic Information Officer (GIO)--The
official coordinating, establishing, supporting, and monitoring geographic
information technology in Texas pursuant to Water Code §16.021(c).
The GIO serves as director of the Texas Natural Resources Information
System (TNRIS) within the Texas Water Development Board.
