International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol XXXV, Part B6. Istanbul 2004
During this decade we witnessed the first PhD degree in
photogrammetry which issued by Tehran university. Now there
are 5 graduated people in the field of photogrammetry and
remote sensing and more than 10 students are working on their
research topics. Due to appropriate relations with good standing
universities in the world of Geomatics, it can be stated that the
qualities of most of these educational programs are compatible
with international standards.
As mentioned before most researches in fundamental contexts
in the field of photogrammetry and remote sensing is carrying
out by universities during MSC and PHD rescarch period.
According to the recent development in number of involved
universities and their students in this field, a good improvement
in research activities can be observed. As a witness to this
claim, the number of accepted papers and research reports from
Iran by national and international scientific conferences and
journals can be mentioned that exceeded from 30 in number
during the year 2003.
Within the past four years, fast development in different fields
of Geomatics was motivated NCC to increase its cooperation
with academic centres in order to promote application driven
researches in them. For better accomplishment of this task,
NCC established the NCC Research Council which aims to
define, guide, support, supervise and assess research projects at
NCC. This council specially promotes research activities which
improves the accessibility and availability of data for the
public. One of the major acheivments of NCC in relation with
Tehran University is the domestic photogrammetry workstation
which now is fully operational within NCC and many private
companies. This cooperation resulted in the first R&D private
company in Iran who is highly active in developing hardware
and software systems in the field of photogrammetry and
remote sensing.
Very recently NCC decided to establish the first Geomatics
research centre in order to develop its role and presence in the
research domain. This centre started its activity in the field of
photogrammetry with a research topic about LIDAR with the
title of: Comprehensive Evaluation of the Potential of LIDAR
for 3D Geospatial Data Collection.
3. CURRENT SITUATION
3.1 Proposed Strategic Plan and Related Projects
In 2002, strategic plan for mapping activities in Iran including
photogrammetry and remote sensing has been proposed by
NCC to the government. It has been designed to fulfil future
national requirements in the field of Geomatics. This plan is
mainly concentrated in the following issues:
= Training and education;
« Standardization and documentation of technical procedures;
= Research and development;
= Privatization;
= Developing the applications of spatial information;
= Revising the legislations in this area.
Although, the present structure has the technical and
educational ability to meet today's needs, but due to rapid
changes in technology and user requirements, a few national
projects have been planned which some of them in relation to
this report can be addressed as follows (some of them have
already begun):
238
= Completion and updating the 1:25000 scale base maps and
NTDB;
= Development of national DEM with 10m resolution;
= Completion and updating large scale digital maps of cities;
= Production of 1:10000 scale maps of rural areas around
cities with more than one million population;
= Development of standards required to fulfil these projects;
= Large scale mapping and development of topographic
database for rural areas with population greater than 200
families;
* Development of Iranian NSDI;
= Development of National Spatial Data Transfer Standard.
This strategic plan and related national projects can guarantee a
stable development of the country in terms of spatial data
production and usage as well as education and research in
Geomatics domain. In any case, many efforts have been made
during last decade to change the situation of the country in
terms of available map and spatial information and a
comparison to ten years ago shows a dramatic change in this
relation. The following paragraphs briefly explain the current
situation.
3.2 Digital Topographic Maps and National Topographic
Database
Fortunately, the current situation of available topographic maps
compared to ten years ago shows a dramatic change not only in
terms of number of map sheets, but also regarding the
restrictions of individual access to geographic information. In
order to explain the current situation in terms of topographic
maps and database, the following projects have to be addressed:
1:25000 scale base map series: This project was started in
199 1using analogue technology and then switched to digital
products. By the end of 2003, the number of digital maps
produced in this project passed the number of 8300. Note
that the country will be covered by about 10000 map sheets
in this scale. The remaining parts mostly consist of border
areas that confront with some security problems for aerial
photography.
In the mean time, preparation phase for updating these data
has been finalized and proper action will be executed during
the year 2004.
= National Topographic Database (NTDB): As a consequence
to new digital technology, NCC decided to create National
Topographic Database of the country based on above
mentioned 1:25000 base maps. The first step was design
and standardization of this database followed by applying
necessary changes to production line. The NTDB standard
was published in 1994 and creation of this database started
at the same time. At the time being, all the produced
1:25000 maps have been entered to this database.
« 1:2000 scale map series of the cities: In 2001, increasing
demand of governmental and private organizations for
reliable and updated large scale maps of cities for various
purposes motivated the MPO to assign responsibility of this
project to NCC. This project started with 630 cities but it
exceeded the number of 900 cities during past three years.
Although, digital maps of about 220 cities have been
produced within this project but still a great number of
cities (about 570 cities) are suffering from lack of updated
