Land Use/Land Cover Change and Its Driving Forces in Shenkolla Watershed, South Central Ethiopia
ScientificWorldJournal, Feb 18, 2021; DOI: 10.1155/2021/9470918

The main data sources for this research were semistructured questionnaires, complemented with field observations, remote sensing imagery, topographic maps, supportive data such as GPS records, and related literatures. This study involved the use of mixed methods to complement each other since the methods have their own weaknesses and strengths. Primary data were collected through extensive field observation, key informant interview, and focus group discussions. Ancillary data (training sites and ground control points) consisting of different LU/LC features and their location points were recorded using a Global Positioning System (GPS) instrument [28]. The images were freely obtained (downloaded) from the USGS Glovis website (http://glovis.usgs.gov/). ArcGIS 10.3 and QGIS v 3.0 software were used to classify the image and to delineate the study area. The acquisition dates, sensor path/row resolution, and the source of the images used in this study are summarized in Table 1.
