The Civil War Preservation Trust (CWPT) is “America’s largest non-profit organization (501-C3) devoted to the preservation of our nation’s endangered Civil War battlefields. The Trust also promotes educational programs and heritage tourism initiatives to inform the public of the war’s history and the fundamental conflicts that sparked it” (from their “About Us” page).
There are many different resources on their site that help bring Civil War battles into the 21st century. In additional to historical images and maps, several key battles have animated videos depicting troop movements (here is the one for the Battle of Fredericksburg). The website provides statistics for each battle, including casualties, the names of commanding officers, etc. There are also virtual tours of historic battlefields, photos of these sites as they appear today, bibliographies of recommended readings, information on historical markers, and the steps for becoming a member. Of course, since their primary focus is on preservation, you can also find information on preservation attempts (from their online newsletter called “Dispatches from the Front“).
