Dear Sir or Madam,
I have recently encountered some difficulties while using the Habitat Quality model. Specifically, I aim to conduct a habitat quality assessment for multiple global regions from 2000 to 2020. Road network data plays a critical role in influencing habitat quality and cannot be ignored. While OpenStreetMap (OSM) is an excellent data source, it only includes global road network data from 2014 onwards. Data for the period between 2000 and 2010 is scarce and of poor quality.
I would like to inquire whether there is a solution to this issue or if there are any publicly available global road network datasets that I may not be aware of. Thank you very much for your valuable time and guidance.
Sincerely,
Jason
