NATIONAL REPORT OF TURKEY ON PHOTOGRAMMETRY AND 
REMOTE SENSING FOR 2000 - 2004 
Turkish National Society for Photogrammetry and Remote Sensing 
KEYWORDS: Photogrammetry, Remote Sensing, GIS, Education, Spatial Information Sciences 
ABSTRACT: 
This report comprises activities, organizations and important events on photogrammetry, remote sensing and 
information in the period of 2000-2004 
1. INTRODUCTION 
Although photogrammetrical applications have a long history in 
Turkey, these were implemented only in one or two public 
organizations for a long time. Historical developments of 
photogrammetric methods have taken place in these 
organizations. 
Depending on the amendments in mapping regulations and 
classifications, private sector have also taken place in various 
applications for at least fifteen years. 
Nowadays, geographical information is a necessity for almost 
daily life. Beginning from the vehicle tracking system, many 
practical applications depend on spatial information which are 
acquired by imagery and data processing. As a natural 
consequence, interest and activities in photogrammetry, remote 
sensing and spatial information fields are growing up both in 
public and private sector. 
2. TECHNICAL ACTIVITIES 
General Command of Mapping (GCM) is the national mapping 
agency of Turkey. GCM is responsible for 1:25.000 and smaller 
scale map production. Two Beechcraft B-200 are used for aerial 
photography with kinematic GPS hardware. 1:35.000 scale 
black-white aerial photographs in digitized format are used for 
25K map production. All steps of the production are 
implemented by digital methods. 1/6 rate of existing maps are 
produced in digital vector format and remaining parts will be 
completed in 6 years. 
Photogrammetric vector data are converted in to ArcInfo format 
to complete the cartographic process for printing. These are also 
data sources of topographic database. 
Orthophoto maps in raster format via CD-ROM's using color- 
negative aerial films are another production of Photogrammetry 
Department. A software called “Orthophoto Presentation 
System” developed in that department is used to present 
existing ortophoto mosaics to the end-users is used. Software 
was developed according to the user’s requirements and able to 
monitor any place in any scale, prepares any part of mosaic as 
output in desired scale and has some other functions.

In February, 2000 GCM started a project, called as 
DIMASMAP (Digital Map Supported Map Applications), 
which aims to develop a software to perform all applications 
done on paper maps, plus 3D visualization and GIS 
functionalities. This project has been completed in 3 months 
with release of the Version 1.0 of the DIMESMAP. This 
software makes use of GCM produced raster maps (JPG), 
matrix data (DTED) and gazetteers (MDB) in a encrypted 
format, so as to protect them from unauthorized use. The 
software itself is also protected by means of a soft lock based 
on hardware-locked user-id, which requires authorization after 
the installation. 
As of the date June 2004, DIMASMAP-Version 1.7 has 252 
functionalities which grouped into 13 modules, namely: 
e Raster Map Applications 
e Vector Map Applications 
e Situation Graphics Applications 
e. 3D Terrain Applications 
e. 3D Simulation Applications 
e Vehicle and Personnel Tracking Applications 
e Traditional Database Applications 
e GIS Database Applications 
e Display Applications 
e Query Applications 
e Measuring Applications 
e  Gazetteer Applications 
e Tools Applications 
DIMESMAP has its own on-line-help system which makes it 
easy to learn and use by all levels of users from an enlisted man 
to the army commander. As of today, DIMESMAP is for 
military use only. Commercialization of this software for 
civilian users is still going on. 
General Command of Mapping (GCM), as the National 
Mapping Agencies of Turkey, has the majority of the 
Topographic Data at national level both in printed - and digital 
forms. These data are comprised of 
e Printed maps at medium and small scales (1:25 K and 
smaller), 
e Raster maps scanned and geo-registered in projected 
and geographic coordinate systems, 
e Digital terrain elevation maps as vector maps in 
various commercial formats (e.g, DGN, ESRI- 
Coverage, ESRI-ArcExport, ESRI-Shape, DXF),
