การใช้ระบบสารสนเทศภูมิศาสตร์ในการกำหนดเขตของหน่วยเลือกตั้ง ในเขตเทศบาลเมืองชลบุรี / พิพัฒน์ นวลอนันต์ = Delineation of the electoral precincts in Chon Buri municipality using geographic information system / Piphat Nualanant
This research studied how to apply Geographic Information System for the delineation of electoral precincts. Under the requirements that the number of voters per precinct should not exceed 1,000 and the travel distance of voters should be less than 2 kilometers, voter distribution data of 1992 from the municipality of Chon Buri were used to test the delineation procedure through the use of the Network Program of the PC Arc/Info. The result was satisfactory. For each precinct, both requirements were met. The longest travel distance for all of the precincts is 894 meters comparing to 1,142 meters of the last election in 1992. In addition, this research also provided programs written in Simple Macro Language of PC Arc/Info and Structured Query Language of dBASE IV such that the delineation, data query and data updating can be done interactively and step by step, by a potential user who has limited knowledge of Geographic Information System. These programs can also be applied for various purposes such as the delineation of the service areas of schools, hospitals, police stations etc.
