1998 Snow Survey for Green Lakes Valley, Niwot Ridge LTER, Colorado
Yearly snow surveys were conducted in the Green Lakes Valley in the City of Boulder Watershed at the estimated peak of snowpack in late spring. Over a period of several days, surveying teams (1 to several people) traversed valley slopes measuring snow depth with avalanche probes. Locations of each depth measurement were recorded as waypoints in Garmin hand-held GPS units (eTrex Legend and eTrex Legend H models). Snow depths were recorded on standardized field sheets along with dates, recorder names, waypoint numbers, and comments. GPS locations were downloaded as text files from Garmin units using Topo! software, specifying NAD83 for surveys conducted after 2009. Download files contained waypoint number, latitude, longitude, date, and elevation. Each file was imported into a Microsoft Excel spreadsheet and snow depths corresponding to waypoints were entered manually from field sheets. Shapefiles were constructed in ArcInfo/ArcGIS from dbf files generated either directly from Excel spreadsheets (before 2008) or after importing into Microsoft Access and then exporting as dbfs. All shapefiles are provided in a UTM zone 13 projection and NAD83 horizontal datum. NOTE: This EML metadata file does not contain important geospatial data processing information. Before using any NWT LTER geospatial data read the arcgis metadata XML file in either ISO or FGDC compliant format, using ArcGIS software (ArcCatalog > description), or by viewing the .xml file provided with the geospatial dataset.
