TN Base Map program moves forward
In a meeting yesterday that I attended along with representatives from a good number of counties in eastern Tennessee, Dennis Pedersen shared the vision for the next four years of the TN Base Map Program (TNBMP). Tennessee is one of the first states in the country to have an entire county-by-county cadastral and ortho program completed. From TNBMP’s inception in the late 90’s, every TN county had its entire parcel dataset digitized and also received new B/W orthos. Many of the orthos are now considered old and technology advancements in new digital orthophotography have caused prices to drop. The next phase will provide the counties with a new ortho every 4 years through a partnership with the Tennessee DOT, which will fly each county by region, capturing 25% of the counties each year. Over a four year period, every county will receive new color 1′ orthos. West TN counties will be the first to benefit from this program with flights beginning in 2008.
