Here we present a geospatial dataset representing local- and regional-scale aquifer system boundaries, defined on the basis of an extensive literature review and published in GebreEgziabher et al. (2022). Nature Communications, 13, 2129,

The database contains 440 polygons, each representing one study area analyzed in GebreEgziabher et al. (2022). The attribute table associated with the shapefile has two fields (column headings): (1) aquifer system title (Ocala Uplift sub-area of the broader Floridan Aquifer System), and (2) broader aquifer system title (e.g., the Floridan Aquifer System).

- 440 features (polygons) stored as a shapefile
- each feature represents one study area defined by GebreEgziabher et al. (2022)
- each feature has a unique aquifer name identified in the field entitled 'Aquifer' (see attribute table)
- some features are sub-areas within a broader, regional-scale aquifer system that is identified in the field entitled: 'BroaderSys' (see attribute table)

When I access the link corresponding to Web Feature Service through GIS software, it will prompt: 000228: Cannot open the dataset. Can you help me to see how to solve it?
