ONLINE MAPPING FOR LANDSLIDE DISASTER PREPAEDNESS IN BO KLUEA NUEA SUBDISTRICT BO KLUEA DISTRICT, NAN

Abstract

Bo Kluea Nuea is a subdistrict prone to landslides due to heavy rainfall and steep slope, thus objectives of this study are to develop online map for landslide disaster preparedness and to disseminate online map to villagers, volunteers and disaster prevention and mitigation officers. Online map shows vulnerable household, evacuation sites and shelters, temporary collective centers, village broadcasts and rain gauges stations. By this online map can be accessed from the QR code. Local communities, volunteers and disaster prevention and mitigation officer’s disaster preparedness knowledge were surveyed before and after using the online map by questionnaires. Sample size were determined using Taro Yamane formula at 95% confident level and error at 0.05, The sample size were 1,488 people from 2,591 (villagers that more than 12 years old). Result showed that villagers’ ability, before use online map, were low level (x̅ = 1.62, S.D. = 1.18), while after using online maps were highest level (x̅ = 4.74, SD = 0.49). Similarity with volunteers’ ability, before use online map, were moderate level (x̅ = 2.48, S.D. = 1.19) and after using online map were highest level (x̅ = 4.81, S.D. = 0.28). For the result of disaster prevention and mitigation officers’s opinion of map using, before use online map, were moderate level (x̅ = 3.25, S.D.= 0.48) and after using online map were high level (x̅ = 4.08, S.D.= 0.82). Moreover, the opinion about online map’s utilization after using online map, were the highest level (x̅ = 4.50, S.D. = 0.50). These results showed that disaster prevention and mitigation officers realized that online map can be a spatial database for landslide disaster preparedness in Bo Kluea Nuea subdistrict.
