Dear friends,

I am using ILWIS 3.3 and 3.8.5 with Windows 7 operating System. When I
import Arcview Shapefiles (projection – UTM, WGS 84, Zone 36N) to ILWIS
(at 3.3 through Import-> Map or Import->GDAL->ArcView Shape; at 3.8.5
through Import-> GDAL->Vector->ArcView Shape) in the result I have 5
files  (*.dom, *.mpa, *.mpap#, *.mpat#, *.mpz#) and projection –
UNKNOWN.
Why ILWIS lost the projection?
How to change UNKNOWN to UTM or how to aviod projection losing?

Thank you,
           Victor

I can only speak for Ilwis 3.8.5. It depends a bit on what the underlying library (gdal) returns. ArcGis and Gdal are not 100% compatible with wkt strings they use for defining coordinate systems. Its unfortunate  (and who knows, it might be an interpretation error on our side of what strings gdal returns). Fortunately you can easily create a new utm system with right zone if you go to the file menu, use the create coordinate system, choose the right projection (utm) and zone and attach that to your map via the property form ( 1 minute work).
