4. Implementation
Implementation of a project of this magnitude and ramifications required effective coordination of the various activities. A Core Committee to oversee the project implementation was constituted by PWD with officials from PWD, C-DAC and MRSAC. Proper work breakdown structures for the activities were prepared and task allocation and schedules for completion was made unambiguous. During the entire project duration, spanning almost two years, regular monthly meetings were conducted to review the progress and sort out the problems. The entire process of data creation - both spatial and non-spatial, required the involvement of a number of engineers and experts of the three agencies. The digital raw data supplied by the MRSAC was printed talukawise and circulated amongst the respective PWD division offices for ground checks. The maps were then updated based on the confirmation obtained through the ground checks conducted by the PWD field engineers. The updated spatial data layers created by MRSAC were then subjected to the quality checking by the PWD officials and C-DAC experts. The success of this entire process (Fig. 3) was ensured through extensive orientation training provided to over 500 PWD field engineers across the state.  Fig. 3 : Project Process Flow The taluka-wise entry of road data for the creation of attribute database was again spread over 250 division offices of PWD, across the state. The individual PWD division offices in a campus are connected internally through a LAN (Local Area Network), while each campus has been connected to the regional headquarters through a WAN (Wide Area Network), which in turn is then connected to a central location. A proper methodology for non-spatial data collection and compilation was formulated. Properly designed data collection sheets were circulated to all the PWD division offices. The data collected through these sheets was then entered in the application software at the respective PWD division offices. All these databases were then merged to form district-wise, region-wise and statewide databases, by replication over the WAN (Fig. 4). Provision for future updation of the attribute database has been planned through its linkage to a completed works database, which is being created as a part of the comprehensive computerization of the department. |
