activities and have instruments for that purpose, besides the
three big organizations mentioned above.
Activities of private companies related to photogrammetry
have been increasing day by day. They especially interest
with the large scale (1/1000 and 1/500) urban mapping,
orthophoto and DEM production and establishment Land
Information System for the requirements of majorities.
Besides the four big private companies, Air Silver also can
be considered as photogrammetric company. Employment
in photogrammetry including all big official organizations
and universities is about 200. That is about 100 in private
sector.

Recently, numbers of person employed in photogrammetry
have been decreasing in official organizations while
increasing in private sector.
2.2. TYPES OF ORGANIZATIONS
Number of private and official organizations providing
photogrammetric production and number of employment
can be shown sequentially in table 2. and table 3. .
Table 2. Number of private and official organizations
providing photogrammetric production.
2.3. APPLICATIONS
Activities of official organizations in photogrammetry can
be summarized as follows :
- Topographical mapping and revision at 1/25000 scale.
- Topographical map production by using stereo satellite
images at 1/25000 scale.
- Forestry mapping.
- Digital mapping of motorways.
- 1/5000 scale standard topographical map production
pertain to rural area cadastre.
- Point determination with aerial triangulation.
- Terrestrial photogrammetric applications in architectural,
engineering and other fields.
- GIS applications
Activities of private companies in photogrammetry :
- Digital mapping and city plans of urban area in large
scales (1/1000, 1/2000 and 1/5000).
- The production of orthophotos and photomosaics in large
scales.
- Digital production of various types of carriageway
mapping (i.e. water, road, railroad, drainage and power
transmission lines).
- Establishment of city information system with digital
data.
- Revision of city maps produced in various scales.
Activities of universities and researching institutions in
photogrammetry :
- Personnel training and education in photogrammetry,
- Scientific researches in photogrammetry,
- Technical consultancy for activities of official and private
sector, in photogrammetry,
- Organizing of various symposiums in photogrammetric
fields.
Primary application field of photogrammetry in Turkey is
topographical and project mapping.
Training and education have the big share in spent time for
photogrammetric activities.
Application of close range photogrammetry is in limited
level and in the fields such as, protection of environment,

Official organizations use mostly analog and analytical
instruments, on the other hand , private companies prefer
analytical and especially digital instruments.
