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: (3) Digital elevation model (DEM), which was downloaded from the Geospatial Data Cloud Available online: http://www.gscloud.cn/ (accessed on 26 April 2020). In the above data, the DEM data, with a resolution of 30 m, can be extracted into slope and elevation. (4) The highway, the primary road and railroad **data** procured from OpenStreetMap Available online: http://www.openstreetmap.org (accessed on 13 July 2020). The population density **data** was provided by Landscan Available online: https://landscan.ornl.gov/ (accessed on 18 December 2020). (5) The 1000 m Normalized Difference Vegetation Index (NDVI) **data** and 30 m land use and land cover change (LUCC) **data** were obtained from the Data Centre for Resources and Environmental Sciences, Chinese Academy of Sciences (RESDC) Available online: http://www.resdc.cn (accessed on 26 April 2020). NDVI and LUCC **data** were obtained by remote sensing image processing. NDVI **data** was based on inversion of SPOT/VEGETATION and MODIS satellite remote sensing and LUCC **data** was generated by manual visual interpretation based on Landsat 8 remote sensing images. (6) China Nature Reserve, the earthquake and landslide vector **data** acquired from RESDC. China Nature Reserve are surface vector data, the rest are point vector data.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
