[EM] Block group map of Texas
I generated some pdf maps of Texas. They are pretty big as they include all the lines that are included in the census data. They would stress even the best of computers. However, it shows the kind of shapes that are included in the census system. County - 1MB (7MB expanded) http://www.electionsciencefoundation.org/temp_images/county.zip Tract - 4MB (32MB expanded) http://www.electionsciencefoundation.org/temp_images/tract.zip Block Groups - 7MB (60MB expanded) http://www.electionsciencefoundation.org/temp_images/tract.zip I also did a block one, but it comes to 420MB.

Re: [EM] Block group map of Texas
I also added blocks for Maine. http://www.electionsciencefoundation.com/temp_images/maine_blocks.zip There are island blocks which are completely surrounded by other blocks. It is probably worth scanning for them and designating them part of the block that they are enclosed by. Unless they have a population greater than a district, it is not possible for them to be placed in a different district to their parent block.
