Duration: February 2000 – June 2000
        Phase I Data Collection involved collecting both social and spatial data. Phase I began several weeks prior to the arrival of the Household Survey teams in Nang Rong. GPS teams were responsible for some initial social data collection in the form of administering the Community Questionnaires in intensive and non-intensive study villages, assembling household and rice mill lists and providing these lists to the Household survey teams. In addition, the GPS teams obtained current market prices for selected items in Bangkok and several major towns in and around Nang Rong district. On March 2, 2000, a formal, monthly district-level meeting was held in Nang Rong town. Around 400 headmen and other village officials from Nang Rong, Chamni, Now Suwan, and Chalermprakeit were in attendance. IPSR faculty introduced the project to the audience, made them aware that interviewers would be visiting their villages in the near future, and asked for their assistance and participation in the survey.

Duration: July 2000 – November 2000
        Spatial Phase II Data Collection was performed in order to map the plangs used by villagers for each of the intensive study villages and match or link the mapped plangs to their corresponding plangs that the villagers reported using in Household Questionnaire Form 6. In the Household Questionnaire Form 6, interviewees were asked to think about each of the plangs that they used and to identify the users of the plangs that were adjacent to each of their plangs in the approximate North, South, East, and West directions. Adjacent users were either from the same village or from another village. The mapped plangs would eventually reside as spatially-referenced digital objects in a GIS layer in the Nang Rong spatial database and each digital plang would be linked to the corresponding socio-demographic household-level data gathered in the Household Questionnaire.
