Introduction

Spatial Information Science

• Geo-technology, as one of the three most
  important emerging and evolving fields, along
  with nanotechnology and biotechnology , U.S.
  Department of Labor, (2004, Gewin, Nature)

15
Spatial Information Science Why?

• role played by geospatial analysts, mining
  satellite images for information to help
  authorities make crucial decisions.
• geospatial technologies have changed the face and
  broadened job prospects across public and private
  sectors.
• private sector hasn't traditionally offered many
  jobs, but location-based services and mapping -
  or 'geographic management systems'- are changing
  the field.
• US 5-billion worldwide geospatial market will
  grow to 30 billion by 2005
• NASA26 of its most highly trained geotech staff
  are due to retire in the next decade, and the
  National Imagery and Mapping Agency is expected
  to need 7,000 people trained in GIS in the next
  three years.

16
Spatial Information Science Why?

• The demand for geospatial skills is growing
  worldwide, but the job prospects reflect a
  country's geography, mapping history and even
  political agenda.
• In the United States, the focus on homeland
  security has been one of many factors driving the
  job market. Another is its vast, unmapped
  landscape.
• European countries are integrating GIS into
  government decision-making, their well-charted
  lands give them little need for expensive
  satellite imagery.

17
Spatial Information Science Why?

• The integration capabilities have extended
  research frontiers across many fields, in the
  areas ranging from ecology to medicine to
  transportation.
• Geographic information science and technologies
  have today become critical components of the
  global science infrastructure both in the
  university and in society.

Definition

• Photogrammetry has been defined as the art,
  science and technology of obtainning reliable
  information about physical objects and the
  environment through processes of recording,
  measuring and interpreting photographic images
  and patterns or recorded radiant electromagnetic
  energy and other phenomena. (American Society for
  Photogrammetry and Remote Sensing (ASPRS))

20
Definition

• Photogrammetry is the technique of measuring
  objects (2D or 3D) from photo-grammes. We say
  commonly photographs, but it may be also imagery
  stored electronically on tape or disk taken by
  video or CCD cameras or radiation sensors such as
  scanners. The results can be
• coordinates of the required object-points
• topographical and thematical maps
• and rectified photographs (orthophoto).

21
Definition

• The name photogrammetry" is derived from the
  three Greek words phos or phot which means light,
  gramma which means letter or something drawn, and
  metrein, the noun of measure.

22
Analytical Photogrammetry

• Analytical Photogrammetry is a term to describe
  the rigorous mathematical calculation of
  coordinates of points in object space based upon
  camera parameters, measured photo coordinates and
  ground control.
• Analytical photogrammetry generally involves the
  solution of large, complex systems of redundant
  equations by the method of least squares.
