<dd>This tech note primarily provides an overview of data collection methods for calculating the volumes of surface mineral material remaining at abandoned mine land sites or the volumes of material removed from gravel or sand sites. The goal of this tech note is to assist BLM field staff in (1) understanding the available data collection methods and (2) determining the most appropriate data collection method for their project. Each data collection method is rated qualitatively based on the following criteria: applicability, level of effort, reliability, and others. The data analysis methods highlighted in this tech note include digital terrain model software, average end area, and geometric calculations</dd>
