chiang mai city
Chiang Mai City
  • In the case study of Chiang Mai city, we utilized the aerial photographs from the 1946’s period from Williams-Hunt collection to compare to the current land use of the year 2000’s from high resolution satellite images, IKONOS, with 1 meter resolution. The two sources of data were geo-referenced to match each other in all area.
  • After the data set were prepared, the study can be conducted to identify the movement of the urban area. How the city was changed? By utilizing the old aerial photographs, we can identify the original water system inside and outside the city.
  • This is a very important topic to study since there are many cases that the new constructions did not consider the water ways in the city. These constructions caused the flooding inside the city when there were heavy rain fall. Only by utilizing this information together, we can study and identify the problem very effectively.

Land Use/Land Cover Study
  • In order to conduct the land use/land cover change study, we need to compare the land use of different periods. As mentioned previously, if we need to compare the land use/ land cover from the period that there is no satellite images available. For example, in the period of 1950’s or before that period, we have to utilize the old aerial photographs of the period of interest. Then the comparison can be made after we perform geo-reference processing to the aerial photographs with the new information, such as the satellite images that we will utilize.
  • By utilizing the information from these old aerial photographs, we can identify the land use/ land cover change of the study area. We can identify the area that had been converted to agriculture area after the period of 1946 when the old aerial photographs were taken. In order to study the series of change of the land use / land cover, we need to integrate information of the interval that we are interested, for example, the information in every 10 years period of the interested area.
