A reminder: The UN's ReliefWeb website contains a wealth of detailed infrastructure and operational information for those who wish to be informed about the state of the region in considering humanitarian efforts now underway.
If you are feeling the need to understand the earthquake in Haiti beyond what is being shown on the cable TV news, this site may help.
Here is the Haiti earthquake master page:
UN ReliefWeb Haiti earthquake page
In particular, the site has a long list of updates, maps, and satellite images and analysis from a huge variety of sources that can be downloaded. Many of the maps are in amazing detail and can promote understanding of what relief agencies are dealing with on the ground in Haiti.
On this page, for example, scrolling down the list you'll find a series of 11 tiled map pages that analyze damage pretty much block by block if not building by building:

Another map shows that there is no "primary-class" road from the DR to Haiti.

You can access info from news sources as well as primary government and NGO/agency sources.
