As a new user of GRASS, what would be the best way to import that data? Ultimately, I wish to reproject state plane meters to state plane feet then use those files to import into a MODFLOW project. Perform the modeling, then export that information back
to GRASS for additional processing.<BR>> <BR>I see in the EPSG database that NAD_1983_HARN for Delaware with units of feet is EPSG code 2880:<BR># NAD83(HARN) / Delaware (ftUS)<BR><2880> +proj=tmerc +lat_0=38 +lon_0=-75.41666666666667 +k=0.999995 +x_0=200000.0001016002 +y_0=0 +ellps=GRS80 +to_meter=0.3048006096012192 +no_defs<BR>Does that exactly match ESRI's 102257?<BR><BR>And the EPSG code for for the CRS with meter units is 2776, as listed at the bottom of your website..<BR><BR>So if you create two locations, one based on each of the EPSG codes, you can then import your data (into the correct location), and reproject to the other location to get units in meters.<BR><BR>> In case there is interest, the web site http://datamil.delaware.gov/geonetwork/srv/en/datadownload<BR>> Thanks in advance,<BR>> Bob<BR>> <BR>> <BR>> <BR>> This mail was received via Mail-SeCure System.<BR>>
