SVO names for basin shapefile from HydroSHEDS #11

Open ankushkhandelwal opened 4 years ago

ankushkhandelwal commented 4 years ago

I have a static shapefile which contains basins from HydroSHEDS database created at level 5. I need standard variable name to define these shapes. The attribute of a shape is just its ID which is a string. Here is the link to the dataset -

https://www.dropbox.com/sh/hmpwobbz9qixxpe/AACPCyoHHAQUt_HNdIbWOFF4a/HydroBASINS/standard?dl=0&subfolder_nav_tracking=1

I wrote a script to merge all continents into a single shapefile file.

Hi @ankushkhandelwal , I have not worked with shape files before, so please bear with me as I get up to speed. From reading the documentation you provide, e.g. here, I believe the variable for the basin id would be:

basin~drainage_boundary__hydrobasins_identification_code

To my understanding from reading the documentation, HydroBASINS has its own coding hierarchy that implements some aspects of the Pfafstetter code as well as some other aspects, so I introduced it as the 'hydrobasins' identification scheme. Is that a correct interpretation? Does this code completely identify the shape of the basin, or are there any other variables you are looking for?

ankushkhandelwal commented 4 years ago

This is great. The id that I am using is being assigned by HydroSHEDS and it is unique for each basin. There are other variables in the shapefiles that come from HydroSHEDS but I am using this dataset only to break the world into pieces, so for our use this is good for now. Also, what would be the associated URI for this one ?

mariutzica commented 4 years ago

Great. The URI would be: http://www.geoscienceontology.org/svo/svl/variable#basin%7Edrainage_boundary__hydrobasins_identification_code I need to add this to SVO so it will not show up immediately in queries. However, you should be able to add it to the data catalog at any time.

Hi Maria, So we just tried to access the variable "basin~drainage_boundary__hydrobasins_identification_code" from the data catalog but it appears it is not there. Please let us know if you have added this already or not. Thanks!

mariutzica commented 4 years ago

Hi Ankush, I had not added it before, but I just added it now so it should be there if you search for it.
