I am still having problems with mercator projections. My source data is in mercator has a latitude of origin of 29.61667. I created a new projected coordinate system with the correct latitude of origin and centeral merdian. The false easting and northing are both set to 0 (to match my source). However, when I bring the data into illustrator with this projection the longitude values are correct, but the latitude is wrong. The latitude readout stays near 0. If my source data is in WGS 84 I can bring it in and then perform a coordinate transformation and point to the same mercator projection I described above and the coordinate readouts are correct. The Mercator projection of your source data, is very specific to the hydrographic mapping, where the ‘latitude of origin’ parameter is both used as ‘latitude of true scale’ and origin of ground coordinates (eastings&northings). The official and more general use of the Mercator projection use the ‘latitude of origin’ as only the definition of the latitude of true scale. This is how the Mercator projection parameters defined by EPSG, and used in a lot of GIS software (ESRI product). This is why in MAPublisher, the ‘latitude of origin’ parameter only sets the latitude of true scale, but the northings are always measured from the equator. To make the projection of your source data work in MAPublisher (and other GIS software), you need to specify the appropriate False Northing (corresponding to the distance from the Equator to the latitude of your choice). You can use the attached Excel spreadsheet to make this calculation. Simply type in a new value in the ‘Latitude of Origin’ field and it will compute the False Northing to use in the MAPublisher coordinate system definition. There is a risk that MAPublisher will try to recognize the coordinate system from the source format. If so, you’ll have to manually specify the coordinate system that you have created with the appropriate false northing. Alternatively, if MAPublisher picks up a coordinate system during the import, click the ‘Specify’ button to open the Geodetic Datasource dialog box and then edit the imported coordinate system with the appropriate False Northing. I will reopen the discussion with our programmers if we should create a second Mercator projection with a different definition of the ‘latitude of origin’. What is the format of your source data? Do you know if the projection definition of your format always use the Mercator latitude of origin as the origin of northings? My source data is a microstation dgn file. There is actually two seperate entries in the source data for Latitude of Origin and Latitude of True Scale. These two values are usually the same in our data and the false northing is set to 0.
