Is there a GIS source that contains the location and type of obstacles along the USA Southern border? Additional meta data would be great as well; when it was install, dimensions, materials, number of repairs, and so on.
all I know is they might have what you are looking for...
They have their geospatial data there.
Homeland Infrastructure Foundation-Level Data (HIFLD) has an Open Data Portal where most of this data can be found.
HIFLD 2018 Data Catalog (
.xlsx) lists all of their open data wares for the year.
Note: if the portal isn't definitive enough, go through the data catalog; searching for "border" returned six results, whereas searching the portal for the borders tag only yields three.
