problem : the as-is grump-reader only takes density data organized according to CIESIN. That is a directory hti_grumpv1_pcount_00_ascii_30 with inside a file htiup00ag.asc. also, the no value is different "-2147483647" instead of 0
go run grump-reader.go -country=hti -tkvdata=/Users/thomaspeugeot/tmp
pop total -110855243345056 ????

With the runtime server, locations seems one degree west by looking into the original file, one sees xllcorner -74.483333333334 yllcorner 18.025000000000 wetther the conf.hit.coord is
"XllCorner": -74,
"YllCorner": 18
As is : population density data is from CIESIN. Free but inacurate in some places.
To be : use landscan. Format is ESRI
