Availability of Chinese data for Visitation & Recreation model

G’day everyone!

I’m hoping to use the INVEST tool to model data for my Masters thesis, looking at the public use patterns of various urban green spaces in Beijing, China.

I know that the Visitation and Recreation model is based on user generated data from Flickr, however this website is among several social media platforms that is currently banned in China (or only accessible by those of the population with access to a VPN)

Is there any possibility of still being able to use this model in the Chinese context? For example, drawing on Weibo data? I know that one of the major partners of NatCap is the Chinese Academy of Sciences, so maybe they have sourced an alternate data source for this part of the INVEST suite?

Cheers,
Georgie

Hi @Georgie,

The dataset used by the InVEST recreation model is indeed based on Flickr data between 2005 and 2017, and it is not currently possible to use other data sources, though I know our Recreation modelling team is looking into other possibilities. I would suggest trying out the model and seeing how it compares with what you’d expect.

After a quick search through the forums here, I also came across this post from @dave that you might find helpful:

Let us know if there’s anything else we can help with,

Hi @jdouglass, thanks for your swift response.

Unfortunately when I run the model for any/all years between 2005 - 2017, I receive no data within my AOI (Beijing). Attribute table pulls up nothing under each of the headers. I’m 95% sure that this is because flickr data isn’t available for China, but just wanted to check in and make sure. What do you think?

Hi @Georgie, Well, that is interesting that there are no results being returned from the model at all, since there are some points in the flickr dataset that correspond to that region so I’d expect there to be some result coming back to you for the Beijing region. This makes me wonder if there’s something else going on. Would you be able to share your inputs and logfile from a recent run with me so I can take a closer look? Feel free to share them here if you’re comfortable with that, or else feel free to email them to me at jdouglass@stanford.edu if you prefer. Any filesharing service will typically be best.

Thanks,
James

Hi James,

I used the file ‘natural.shp’ as my AOI, and have attached here the log file from a recent run, as well as the results.

What am I doing wrong?

Georgie

Thanks @Georgie! I don’t see your inputs in my inbox, though, and it doesn’t look like they all attached to this forums post either. Could you try uploading them to a filesharing service and then sharing the link to the directory?

Thanks,
James

Ok take two! Try this link: https://drive.google.com/drive/folders/1zEHfjfDr4uy3qJD1e7VNTIR5XwPSW3y1?usp=sharing

Let me know if this doesn’t work…
