Publication of 1:25,000-scale US Topo maps in Alaska began in July 2013. The production schedule is determined by availability of IFSAR elevation data and SPOT imagery provided by the Alaska Statewide Digital Mapping Initiative. 412 maps were produced in 2013. At least 700 are planned for 2014, with increasing numbers in the following years. More than 11,000 maps will be required to cover the state, which will take approximately 6-8 years.
