Resource Abstract:
- description: (<a href="http://maps.vcgi.vermont.gov/gisdata/metadata/VTORTHO_0_15M_CLRIR_2017.htm" target="_blank">Link
to Metadata</a>) This metadata record describes the acquisition and production of 15 centimeter ground sample distance
(GSD) natural color and color infrared digital ground orthoimagery covering a portion of Vermont State. The digital orthophotography
and color infrared digital orthos are composed of 24 bit natural color digital orthos with a 0.15 meter GSD. Geographic extent
is limited to specific buy-up areas in central Vermont including portions of Addison and Chittenden counties, approximately
30 total square miles. Poor weather and ground conditions precluded capture of all areas originally planned. Product: 15-centimeter
color orthoimagery tiles (uncompressed GeoTIFF and compressed JPEG2000). Geographic Extent: The 15 centimeter buy-up areas
were limited to specific areas in central Vermont within portions of Addison and Chittenden counties, approximately 30 total
square miles. Dataset Description: The Vermont 2017 Imagery project called for the planning, acquisition, processing and derivative
products of imagery data to be collected at an ground sample distance of 15 centimeters.Project specifications are based on
the ASPRS Positional Accuracy Standards for Digital Geospatial Data. The data was developed based on a horizontal projection/datum
of NAD83 (2011), State Plane Coordinate System Vermont, meters. Raw imagery data was produced in 16-bit 4-band (RGB-IR) uncompressed
format, then processed to create 24-bit 4-band (RGB-IR) orthorectified tiles. Compressed orthoimagery was produced in JPEG2000
format. An additional set of uncompressed GeoTIFF and compressed JPEG 2000 data was produced in black and white. A total of
97 of the originally planned 712 tiles were produced with a tile size of 900 meters x 900 meters. Tile names use the following
naming convention &quot;VT_(TILENUM)_(YYYYMMDD).(FileExtension)&quot;, where TILENUM = the 8-digit value of the TILENUM
attribute in the master index files YYYYMMDD = the flight acquisition date (or majority date) for that particular tile. Ground
Conditions: Imagery was collected in spring of 2017 during minimal shadow conditions. In order to post process the imagery
data to meet task order specifications, Quantum Spatial utilized 2 checkpoints provided by the Bryant Associates, Inc. These
checkpoints were established throughout the project area and used to check the accuracy of the data.; abstract: (<a href="http://maps.vcgi.vermont.gov/gisdata/metadata/VTORTHO_0_15M_CLRIR_2017.htm"
