Abstract:
This dataset (MISC_0_3M_CLR_2008) includes truecolor ortho imagery covering an area north and south of the VT/Canadian border. VCGI extracted the imagery from a larger dataset developed by 3001 Inc for the Federal government. The MISC_0_3M_CLR_2008 extract is limited to all collected imagery north and south of the VT/Canadian border. The imagery has been kept in its native coordinate system (UTM zone 18 and 19).
For this dataset, the natural color orthoimages were produced at 0.3-meter pixel resolution (approximately 1-foot). The design accuracy is estimated not to exceed 6 meter horizontal RMSE for locations within the United States. Each orthoimage provides imagery for a 1500-meter by 1500-meter block on the ground. The projected coordinate system is UTM with a NAD83 datum, spheroid GRS80. There is no image overlap between adjacent files. The naming convention is based on the U.S. National Grid (USNG), taking the coordinates of the SW corner of the orthoimage.
Purpose:
These data have been created as a result of the need for having geospatial data immediately available and easily accessible in order to provide geographic reference for federal, state, and local emergency responders, as well as for homeland security efforts. Orthoimages also serve a variety of purposes, from interim maps to field references for earth science investigations and analysis. The digital orthoimage is useful as a layer of a geographic information system. These data can be used to provide reference information for web browsers and for map applications at a scale of 1:100,000 or smaller.

Attribute_Accuracy:
Attribute_Accuracy_Report:
Sample points taken from overlapping areas of adjacent image frames along a single flight line and between strips along adjacent flight lines are typically consistent to the 2-3 pixel level. This not only ensures that a consistent mosaic can be created from the adjacent frames and image strips acquired with the DMC digital frame mapping system but also means that the images have good precision and as a group are spatially self-consistent.
Logical_Consistency_Report:
Compliance with the accuracy standard was ensured by the use of photo identifiable ground control points and/or the collection of airborne GPS data.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The accuracy value for locations within the United States was determined by measuring photo-identifiable control points collected with GPS survey methods in the orthophotos.

Source_Contribution: Aerial imagery was captured with a Z/I Digital Mapping Camera.
Process_Step:
Process_Description:
Ground control consisted of photo identifiable surveyed points within the United States. The imagery was collected at an average altitude of 9843 ft above mean terrain (AMT) using a frame-based Z/I Imaging Digital Mapping Camera (DMC). Overlap between adjacent frames along the flight line was approximately 60% and overlap between adjacent flight lines was approximately 30%. Corrections for camera and airplane exterior orientation (EO) variations were made with input from a combination of ground-, plane-, and space-based survey inputs (e.g., ABGPS, IMU, CORS Stations, Base Stations). The DMC collects 12-bit image data per channel which are resampled during post processing to standard 8-bit image data. The reduction in dynamic range (from 4,096 to 256) is performed in a manner designed to capture the greatest amount of information in each image, and preserve bright and dark values. Image quality was verified during the post flight review phase. Factors considered during this review included but were not limited to the presence of smoke and/or cloud cover, contrails, light conditions and sun glint. Pan-sharpened red, green, blue, and NIR bands were combined to generate digital image frames. Geometric correction of mosaicked frames of land areas within and laterally contiguous to the United States was performed via aerial triangulation and orthorectification using a recent DSM of the area provided as GFI (SRTM2, DTED2, Intermap NEXTmap USA, Canada NED, Mexican Border Lidar), and supplemented with higher resolution DSM data where readily available. The vertical accuracy of the DSM varies based on the elevation postings of GFI products and requirements thereof. Color balancing was performed to reduce radiometric variability between frames, and seamlines were generated using both automated and manual methods. Project specified tiles of the red, green, and blue bands were extracted from the mosaic to produce a natural color digital orthophoto image map. Final image tiles were reviewed for artifacts and anomalies and adjusted as part of quality control procedures. When necessary, local corrections to the imagery were performed to minimize such effects.

Copy of boarder imagery provided to VCGI by USGS. VCGI extracted portions of AOI #055 and #056 falling north and south of the Vermont/Canadian border. VCGI tweaked the file names to comply with VIL naming conventions. VCGI kept the data in its native coordinate system, UTM zone 18 and 19. VCGI created JPEG2000 versions, created metadata based on metadata provided with the data and posted everything to the VCGI Image Library (VIL).

Entity_and_Attribute_Overview:
Natural color orthoimagery is organized in three color bands or channels which represent the red, green, and blue (RGB) portions of the spectrum. Each image pixel is assigned a triplet of numeric values, one for each color band. Numeric values range from 0 to 255. Pixels outside the project boundary are represented with the numeric value of 0,0,0.
