A major expansion of the mid-atlantic LIDAR map is currently underway. This is a huge project that I've been working on for months. Right now, the bottleneck is the amount of rendering time required, my computer is processing data 24/7 and it's going to take two or three more weeks before I'm done. My estimate is 18 million new tiles with a total size of about 500gb. This is actually very efficient, I had to download around 4,500 LIDAR DEM files from the USGS totalling about 2.4 terabytes. But lots of time-consuming processing is involved.
When completed, the entire map will be about 40 million tiles and 1.1 terabytes. Am planning to rename it "Northeast LIDAR" since it has expanded way beyond the bounds of the "Mid-Atlantic".
But for now, this is just a "heads up" because I'm going to start uploading bits and pieces to the server which might affect performance at times. There will be around 50 big "chunks" of data to upload and each one has to be individually de-compressed/installed. Not ready to make a real estimate, but hopefully it will be completed by the end of this month. Will post updates here from time to time.
When completed, there will be 2d and 3d grayscale versions in the same style as the existing Mid-Atlantic map. High resolution elevation readings will also be available through the whole area and you'll be able to view it in the terrain viewer as well. Will have to see how much disk space is left when I'm done. Am hoping there will be enough left to expand the 2023 USGS/NAIP aerials to this area as well (they now match the existing Mid-Atlantic coverage). They are used to create 3d aerials in the terrain viewer.
Beyond that, am considering adding another terabyte of disk space (which would increase the total to 3tb) when I renew the server lease at the end of the month. This would allow further expansion to the South and West to match the 24k Legacy Topo coverage area. Would like to expand the street and hybrid maps to a larger region as well.
