[Gvsig_english] Congressional districts, a nicer US map

[Juan Lucas Dominguez Rubio]

Hello, Roger
 
The shapefile with the congressional districts you mentioned uses an international coordinate system, in which the outline of the US does not look very good (Alaska and Maine, for example, look awful). Generally, US maps use a different (nicer) coordinate system and remote states like Alaska or Hawaii are re-scaled and moved to printer friendly (false) places. Here are some random examples:

I have changed the coordinate system of that shapefile to make it look nicer, and have moved Alaska, Hawaii and Puerto Rico to the place they usually are in national US maps. If it's useful to you, you can download it from:

All the shapes still have the official congressional district ID, of course, so you can map as many bills as you like, and with gvSIG's symbology and layout options, your maps will look as nice as this one:

(Perhaps you don't even need to know this, but in the new shapefile, the US mainland is in the coordinate system EPSG:3083)
 
Cheers,

Asunto: [Gvsig_english] opening a MapInfo file



As someone new to GIS I don't know if I can convert a set of MapInfo (ESRI) files so that the map can be opened in gvSIG. The group of files that together describe a map in MapInfo end in .ID, .IND, .MAP and .TAB. Does anyone know if it is possible to open this in gvSIG, and how it's done?

 

Thanks,

 

Roger Taylor
