[maplab-users] The right projection for "non eart" objects in MapLab
Sat, 25 Jan 2003 21:54:15 +0100
Thank you, FRED, for your reply to my MapInfo .tab import problems.
I've resolved this issue following your clear guidelines.
However I've got another questions: after importing and creating new layers (using previous Mapifo .tab files), I've created a new .map Map File with MapEdit.
Well, files I've imported aren't georeferenced, which means they have got "non earth" coordinates, using a common Mapinfo definition.
Moreover these files reference to a different part of the world, specifically to a precise part of Italy (with a linear extension of 200 km).
In my project I've used default system projection of your file relative, instead, to Lambert Conformal Conic projection for Canada (I suppose).
The output, in MapBrowser, is a Map file with no formal error but, nothing is visible in the map window: I think my layers are too small or too big for a correct visualisation in the map.
So, I wonder (if I wan't to georeference my data), if you may suggest which settings (scale, zoom, projection) might I use in this my project.
Thank you in advance for any help.
