The Horizontal Positional Accuracy Values are 0.50 meters (Boston-Providence and Worcester) and 0.52 meters (Springfield). The design accuracy is estimated not to exceed 1.52-meters NSSDA 95% confidence (0.88-meters Root Mean Squared Error (RMSE)) XY (0.62 meter RMSE X or Y). Spatial Data Quality - Horizontal Positional Accuracy The horizontal datum was the North American Datum of 1983 (2011), and the vertical datum was the North American Vertical Datum of 1988. This VRS network is consistent with the National CORS at the centimeter level. The KeyNetGPS Virtual Reference System (VRS) service was used to georeference each station. The National Spatial Reference System (NSRS) was used to provide control for the network. was contracted by Fugro to provide ground control survey to support photogrammetric mapping and blind QC points. The source imagery is cloud free, and was acquired in generally leaf-off conditions.
at about 2,896 meters above mean terrain during mid to late April in 20. The raw ADS80 image data were collected by Fugro EarthData, Inc. These data also support The National Map. These image data were created to provide easily accessible geospatial data which are readily available to enhance the capability of Federal, State, and local emergency responders, as well as plan for homeland security efforts. It can also serve as a reference layer or basemap for myriad applications inside geographic information system (GIS) software. This digital orthoimagery can serve a variety of purposes, from general planning, to field reference for spatial analysis, to a tool for data development and revision of vector maps. View Index Map (7MB PDF) of available imagery (based on the 2013/2014 Aerial Imagery Index layer). Pixel resolution is 0.3 meters (30 centimeters), or approximately one foot. Each band has pixel values ranging 0-255. Image type for all of the areas is 24 bit, 4-band (red, green, blue, and near-infrared RGBN) portions of the spectrum. The rest of the state was captured in 2014. In 2013 those areas were the greater metropolitan Boston, Worcester and Springfield areas. Geological Survey contracted for true-color imagery covering three urban areas in Massachusetts as defined by the USGS.

The direct download link is (if this doesn’t work then try the reddit link above):
The link for the tool is on this sub-reddit post: This tutorial shows how easy it is to use from start to finish.
Import google earth into terramodel simulator#
There’s an amazing tool over on the /r/FS2020Creation sub-reddit called the Google Earth Decoder and it lets you simply select an area of a map and then it automatically pulls down the Google photogrammetry data, generates the model files in a flight simulator 2020 ready format.Īll you need to do is drop them into a scenery project, build and you are then ready to fly over the custom Google photogrammetry scenery in Microsoft Flight Simulator 2020!
Easily bring in Google Maps Photogrammetry Data into Flight Simulator 2020 with Google Earth Decoder ** MAKE SURE YOU HAVE THE MSFS 2020 SDK INSTALLED: WATCH HERE … **
