3.1 Buffering refers to the process of creating a buffer zone or area around a feature, such as a river or a road, to protect it from potential disturbances or to manage the effects of the feature on the surrounding area.
3.2 In farming, buffering involves planting vegetation or trees around fields or waterways to reduce soil erosion and nutrient runoff. This can help to improve water quality and protect nearby ecosystems. Buffering may also involve the use of physical barriers or structures to prevent soil erosion or reduce the impact of wind and water on crops.
3.2 Attribute data refers to qualitative or categorical data that describes a characteristic of a feature, such as the type of vegetation or the land use of a particular area. Secondary data refers to data that has already been collected and is available for use, such as satellite imagery or government statistics.
3.3.1 One way to collect data about the topographical map is to use surveying techniques, such as using a transit or total station to measure elevations and map out the topography of an area. This can help to create detailed maps that can be used for a variety of purposes, such as land use planning or resource management.
8.4 The method mentioned in 3.3 is a primary data collection method, as it involves directly measuring and collecting data about the topography of an area. Secondary data, on the other hand, is data that has already been collected and is available for use.
