I have a projected shapefile created by MapWindow 4.x that loads OK in that program but which is way off when reprojected "on-the-fly". Here are the prj contents:

PROJCS["unnamed",GEOGCS["NAD83",DATUM["North_American_Datum_1983",SPHEROID["GRS 1980",6378137,298.257222101,AUTHORITY["EPSG","7019"]],TOWGS84[0,0,0,0,0,0,0],AUTHORITY["EPSG","6269"]],PRIMEM["Greenwich",0,AUTHORITY["EPSG","8901"]],UNIT["degree",0.0174532925199433,AUTHORITY["EPSG","9108"]],AUTHORITY["EPSG","4269"]],PROJECTION["Albers_Conic_Equal_Area"],PARAMETER["standard_parallel_1",29.5],PARAMETER["standard_parallel_2",45.5],PARAMETER["latitude_of_center",23],PARAMETER["longitude_of_center",-96],PARAMETER["false_easting",0],PARAMETER["false_northing",0],UNIT["Meter",1]]

I would be glad to send the entire shape file (it is small) if that would help.

I am actually needing to get this fixed in an application I have developed using the MW6 libraries, but it is easy to reproduce using the MW application too.

Could you say whether this is related to one of these bugs? http://dotspatial.codeplex.com/workitem/list/advanced?keyword=projection&status=All&type=All&priority=All&release=All&assignedTo=All&component=All&sortField=Votes&sortDirection=Descending&page=0

Or perhaps, one of the open bugs? http://dotspatial.codeplex.com/workitem/list/advanced?keyword=projection&status=Open%20(not%20closed)&type=All&priority=All&release=All&assignedTo=All&component=All&sortField=Votes&sortDirection=Descending&page=0

I reviewed the bug reports and my issue doesn't seem to be similar to any of them. No error message occurs. When I load the shape file and have MW auto-reproject, the shapes are way out in the middle of the Atlantic Ocean rather than in Florida, but as I said, the shapefile loads fine using MW4.

Let me know if the shape file would help.

Feel free to create an issue and attach the shape file (and steps to reproduce problem and the expected result -- perhaps a screenshot from MW4) on the DotSpatial site: http://dotspatial.codeplex.com/WorkItem/Create.

Once it is fixed in DotSpatial, it will bubble up to MapWindow 6.

Thanks for your reply. Oddly enough, the exact same file now appears to be projecting itself properly (no DLLs or files were changed). If I can reproduce the problem, I will certainly post the file as you suggest.
