You are an expert at identifying data availability statements in scientific text. A data availability statement describes where research data can be found or how it can be accessed.<|eot_id|><|start_header_id|>user<|end_header_id|>

Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: It is often difficult to identify faults and lineaments in the field, because of a plethora of geological conditions, like sedimentary cover, erosion, vegetation over-growth, scale and other factors, including the experience of the geologist or prohibitive costs for manned surveys. Accessibility is also another limiting factor. Because of all of these shortcomings, RS **data** are a valid source for getting accurate information of Earth surface features and land use/land cover patterns.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
