Hi, It looks like your ECW file has a RAW projection - this means that it does not have any lat/long or Easting/Northing information in it. You can only do coordinate conversions etc on file that are not RAW, because there is not conversion function. You will need to register your ECW files. This usually means that they need to be rectified using ER Mapper (this step is usually done before compressing the data).
Hope this helps. cheers Mike > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED]]On Behalf Of ricoh starter > Sent: Tuesday, 23 July 2002 8:37 PM > To: [EMAIL PROTECTED] > Subject: the Geographique Projection database > > > Hello, > > Am tryin to include a function like in the sample15.htm > of ermapper, to show lattitude and longitude of a point on > a ecw photo by clickin on it. > So as a test I took the code of the sample and I changed > only the image, but I got an error message: > "coordinate conversion failed" > Unknown map projection > could not setup coordinate system to perform the conversion > to lat/long.This is due to the Geographic Projection > Database being unable to locate the appropriate data for > the projection RAW. > How can I customize that sample to test it with my own ecw > photos? > Do I have to create a database of coordinates ? > > Thanx for any answer > > Tony, France > ______________________________________________________ > Bo�te aux lettres - Caramail - http://www.caramail.com > > ----------------------------------------------------------- To make changes to your subscription, please visit our website, http://www.ermapper.com/technicl/ermapperl/index.htm
