Hi, Attached below is an extract from a set of FAQs I am writing. They concern converting S57 to MapInfo.
Basically you need to set the Format Attributes that relate to your destination format symbology, for example mif_symbol_size or mapinfo_pen_color The FME Readers and Writers Manual (in the online help or available at www.safe.com/download) will give you the full list of Format Attributes for any format. You can set these by exposing them in your destination Feature Type and setting with a constant, or by creating them with an AttributeCreator transformer. Hope this is useful, Regards, Mark Mark Ireland, Product Support Engineer Safe Software Inc.

Why? According to the official S57 specification document... "The model... does not contain any rules for the presentation or display of information... Therefore the presentation of information is considered to be independent of its storage. Different applications must provide their own specific presentation model" In other words if you open the S57 data in an S57 viewing application then you will see symbols and colours not because the S57 data holds this information, but because the viewing application is automatically symbolising the data according to its own set of rules (its "presentation model"). If you convert the data from S57 to, say, MapInfo using FME all of the available information is carried across. You will not see the same display in MapInfo as in the S57 viewing application because MapInfo is not automatically symbolising the data (NB neither will the FME Universal Viewer). Your options are to either use FME to set MapInfo format attributes to simulate the S57 viewer display, or by applying these properties within the MapInfo environment. ------------------------------------------------------------------------ ----- When I convert my S57 data to MIF/MID the soundings do not have an attribute for depth. Why? As with symbology (see above) the only reason you are seeing numbers representing a sounding in your S57 data is that your S57 viewing application is automatically converting the Z value of the each sounding feature into an item of text annotation. If you convert the data from S57 to another format, FME does not create an attribute to hold sounding depth because there is no such attribute in S57. Each sounding feature will be in 3D with the Z coordinate representing depth. Because MapInfo Interchange Format (MIF) does not support 3 dimensions the Z coordinate is being lost. Therefore you are getting neither an attribute or a 3d feature. The extremely simple solution to this is to add a CoordinateFetcher transformer in your workspace, just after the soundings Feature Type. A CoordinateFetcher will retrieve the Z value of every sounding feature and place that value into an attribute of your own creation. ------------------------------------------------------------------------ ----- When I convert S57 to MapInfo I get the message "MapInfo file 'myfile.tab' could not be opened" or "unable to create new table" when I convert or open the TAB file in MapInfo. Why? The issue is that the S57 schema has character fields that are 254 characters in size and therefore too long for MapInfo to handle correctly. Because this is a limitation of MapInfo it is something that cannot be easily resolved by FME. The solution is to modify the output schema in Workbench to make destination fields have fewer characters. To preserve attributes that are 254 characters long you'll need to split them into sections and write each section to a separate MapInfo attribute. ------------------------------------------------------------------------ ----- > -----Original Message----- > From: Shamim [mailto:[EMAIL PROTECTED] > Sent: Thursday, March 10, 2005 8:25 PM > To: [email protected] > Subject: [fme] s57 feature colors > > > > Hi > > I would like to know how to extract the s57 chart feature > colors into other format , for example mapinfo ?. > > Thanks. > > > > __________________________________ > Do you Yahoo!? > Yahoo!
