Yellowstone River Corridor –
Yellowstone County, West Half
Triangulated Irregular Network Elevation(TIN) Data
ESRI Generate Format
September, 2004
A collection of data files, each covering a 1200x1200-meter area, is available for the colored parts of each of the rectangular areas shown on the map below. Click on a rectangle to download the data for that area. Most of the files are between 20 and 50 megabytes in size. All of the data are in Montana State Plane Coordinates, NAD83, units meters. These data are in ESRI "generate" format and must be converted by you to a format that is useable by your software. See the FGDC Metadata for these data for instructions on using ArcMap to convert the data. You may also download all the files at once, at a file size of about 405 megabytes.
These TINs were derived from LIDAR (Light Detection and Ranging) data collected by an ALS40 sensor.
These data are also available in TIN format at:
