  24. Please rate each software functionality with respect to the priority for including this functionality in a hydrologic information system - USU

  25. Independence - USU:Please indicate the following on a scale of 1-5, where 1=not important, 5=essential HIS software should work independently from any 3rd party software HIS software should work on all computer systems

  26. Independence - CUAHSI:Please indicate the following on a scale of 1-5, where 1=not important, 5=essential HIS software should work on all computer systems (Windows, Linux, Mac, Unix) HIS software should leverage commercial software systems (e.g. ArcGIS, SAS) HIS should be implemented using open source software

  27. List data standards and file formats that you think CUAHSI should adopt - USU • NetCDF • check the ALMA convention for Land Surface Modeling • Grib • USGS • NASA - hdf

  28. Are there data for which CUAHSI should define standards - USU • Standards are important, but I do not know what they all are. • Streamflow, Precip, Landuse, Topography, Landcover • Unpublished data in technical reports must be protected, esp when graduate theses and dissertations are involved • Of course, mostly in terms of denomination of the variables. Check ALMA standards as an example. • Time series of any sort should have a standard that controls how they are stored and distributed (this is primarily so that qualifying comments or metadata are not lost). • Data should probably be available in a variety of export formats. • EPA storet- have good chemical data AND flow from the same sample site. Otherwise it is pretty useless.

  29. List data standards and file formats that you think CUAHSI should adopt - CUAHSI • Time series • Space time grids • Some image formats • Hydrologic Observations • ISO • HDF • NetCDF • NASA DIF • GeoTiff • XML based formats • At least conversion from difficult data formats • Flat files • Data model for time series needs more development • How should I know? I’m just a user. • Any raster grid supported by ESRI • Ascii, shapefile, MS Access, XML • XML, XML, and XML

  30. Are there data for which CUAHSI should define standards - CUAHSI • Probably • Transboundary datasets • Sediment transport • Domain specific data – whatever is going to be offered to users • Adapt existing standards • In situ observational data – such as SCAN network data • Metadata format and ontology structure • Vector data, raster data, image data

  31. USU

  32. Rate the ease of access to hydrologic data and information - CUAHSI

  33. USU Other data mentioned Water Use/Diversion data - 2 ET, Groundwater level, Water Quality/Chemistry, Energy balance components (latent and sensible heat)

  34. Rate the priority for data inclusion in HIS - CUAHSI

  35. Other National Datasets you think should be considered - CUAHSI • Corps of Engineers Stream stage/discharge • WRRI – Institutes • Reservoir storage/elevation/chemistry (Corps of Engineers, Bureau of Reclamation) • National orthophotography • Higher resolution HUCs • Urban/anthropic/water-related infrastructure • General geology • Population density • Various NRCS/WCC & NOHRSC data • NADP precip chemistry • Stream sediment data • Hydrogeologic data (K, Chem, etc.) • Snow courses • Vegetation maps • US Census/population data • Ecological data/ecoregions • Agricultural census data

  36. Local Datasets that you think should be included - USU • Geomorphic/Channel Characteristics, (.shp) • Fish Distribution and abundance (Excel) • Other biotic data on streams( Excel) • Abiotic data on streams (Excel) • LIS (Gribs) • U Washington (NetCDF) • Unidata • Real time river diversions and reservoir elevations (txt) • Real time water quality monitoring data • Real Time climate/weather observations (like Mesowest) • Local government records indicating land use changes • US govt Population Census data • Meteorological and edaphic state variable data from CSI loggers • Precipitation (ASCII, Excel)) • Soil Moisture (ASCII, Excel) • Soil temperature (excel) • Soil characteristics (ascii) • Meteorological data (wind speed, humidity, air temperature, solar radiation) (ASCII)

  37. Local Datasets that you think should be included - CUAHSI • Borehole data – geologic electric and geologic logs – locations • Seismic reflection lines • NPDES sites • Geologic surface profiles with original data points • Groundwater raw water chemistry • Irrigation diversions • Pressure, moisture, concentration (SQL) • USGS FRI – Forest growth data • National rangeland condition data • US breeding bird survey • Airborne Lidar – filtered bare earth and first return • High resolution orthorectified aerial photographs • Various mountain datasets • RAWS & other mesonets • Precipitation isotope data • Calsil (data system), Cdoc (data system) • Weather Mesonets • High level land use • High resolution topography • Land management practices • Water management practices • Model input for specific watersheds • Met and flux tower • Realtime water quality data • Diversions, water management, water rights • Water use • GAP analysis

  38. USU

  39. Additional Comments/Suggestions • Transboundary approach should be included into the HIS project (e.g., all watersheds along the US/MX border are binational on both surface and GW hydrology • Need tools to easily register raster data at different scales (e.g., MODIS, Landsat, orthophotos, NED, gridded climate) • Consider uncertainty • Consider anthropic influences • Prioritize ingestion and dissemination of data, methods for data visualization, manipulation and, analysis • Need attention to ease of use, intuitive interfaces, responsiveness, etc. • Don’t forget the hydrogeologists, hydrochemists, and stream geomorphologists • Is there more interest in accessing unfiltered data than model results? • Each observation needs quality information (adequacy of time series data model) • Priority on simple data model for hydrologic observations with derivatives for groundwater, streamflow, etc. Priority 2 = data fusion and assimilation technology • Needs – integrated models, data to models, standard models, software for analysis of model output and uncertainty
