55 Photogrammetric Compilation The Aerial triangulation calculations were performed using PATB-RSG software, which the project received as a B release. This project was the first big project where this software was used. Two photogrammetric experts, one from Indonesia and one from Norway went to Germany to get training in using this software. The photogrammetric section was established in July 1993, the section had four stereo instruments (Zeiss P3) and nine employees. Three of the employees were expatriate experts. Along with the teaching and training activities, production routines were established and operator handbooks written, all based upon the specifications for the project. Two of the Indonesian employees had newly graduated from University within the field of geodesy and photogrammetry, the other local staff had background from high school or additional course within computer science. After approximately half a year with training activities and another half year with production under close supervision, new local employees were hired and trained. At this time three additional new stereo instruments arrived, which mean that production could go parallel to the training activities. The new staff were trained by the senior Indonesian Staff, based on the training programmes made during the initial training period. It was noticable that the training gave better results when the instructors were fluent in Bahasa Indonesia. After half a year the new photogrammetric operators were in full production. At peak production in the photogrammetry there were 24 specialized operators working three shifts a day on seven stereo instruments. At peak production about 45 map sheets were produced monthly. Two photogrammetric instruments were available to the Project Advisory Group at BAKOSURTANAL to perform quality control at the digital geographic information collected. Field Compilation The land surveyors with experience from the scale 1:50.000 topographic mapping in East and South Kalimantan were still employed by PT.NARCON. These Surveyors were now active in hiring and training of new young surveyors in field compilation. BAKOSURTANAL have establish routines for field compilation that should be followed by Blom-Narcon Cooperation Surveyors. The procedures were for the Surveyors to verify the map content for completeness and correctness. The basis for the field compilation was a colour plot that contained all information that were interpreted from the aerial photographs. They should collect all additional geographic information according to the map specifications. Twenty five Surveyors are at present performing the field compilation and in addition to this five operators are digitizing the field information using AutoCad Software. The digital information collected during this production process is the geographical names and the additional and corrected geographic information collected in the field. Quality control routines are established for the geographic information digitized prior to the transféré of the information into the central database. Database Establishment This is not on production activity by itself, but a result of the collection of all the digital geographic information produced. The project has defined different databases which again are basis for quality control, approval and invoicing. Database “O’", is a result of an automatic procedure that have been set up to transféré information collected during photogrammetric compilation to the cartographic editing process. This procedure establish a database per mapsheet. Several preprocessing programs are running to give all information its initial value for date, quality and accuracy. The batch processing procedures runs round-the-clock, is unmanned and checks for more work every half hour. The hardcopies produced are checked by the photogrammetry section and later they are transferred to the editing archives, along with a MAIL message to notify that the cartographic editing may start. The digital geographic information collected for one map sheet it now at a production level called Database “0” and ready for approval by the Client. The Cartographic editing is divided into three phases, resulting in Database 1, 2 and 3. They are five local employees running the computer systems in the production office, all trained by the experts on the project plus different courses they have followed outside of the office. There are running the local network two DEC/VAX server operating under VMS operating system connecting 25 Work Stations. There are one Windows NT server connecting 30 PC’s of different capacity. All back up routines and plotting routines are handled by the computer section. Cartographic Design Database 1; the maps are annotated with nine different landuse types and during the batch processing for Database 1 there are generated closed polygons for all area symbols. Contour lines are generated from a terrain model generated from all 3D information collected during photogrammetric compilation. The contours are manually labeled. The Database 1 plot in colour shows the complete map legend with patterns and symbols. Database 2; is generated when the digitized information from field compilation are merged with the Database 1 information. Here the real cartographic work starts with nameplacings and using the correct line signatures and line widths. When the editing of this database is completed and approved by the Client this is regarded as the final geographic database. Database 3; is produced for the purpose of offset printing. The geographic information produced for Database 3 is sorted according to printing colour and transferred to Corel Draw for final refinements of text fonts, symbols and patters/screens. Check plots are produced for each printing colour and approved by the Client prior to being printed out on an in- house image setter at 2000 dpi. The production of Cartographic Design employs 30 employees of whom two are expatriate experts. The training of the
