GIS Web Mapping

As more and more municipalities, irrigation districts and other water related entities begin to utilize the World Wide Web, the WWDO and the WRDS have taken the opportunity to make water and climate data available using customized ArcIMS services. Customized ArcIMS applications allow users to examine numerous aspects of Wyoming water and climate simultaneously, and this approach provides “one stop shopping” for access to important sources of data and information. These efforts are funded by the Wyoming Water Development Office, and these tools will be a key component of updates to the State Water Plan.

• PRSIM Climate Data Server
  PRISM climate data, provided by Oregon State University (http://prism.oregonstate.edu/), uses point measurements of precipitation, temperature, and other climatic factors to produce continuous, digital grid estimates of monthly, yearly, and event-based climatic parameters from 1895 through 2010.

  Using a routine to query a specific PRISM raster cell, WyPCDS retrieves monthly and annual climate data for mean, maximum, and minimum temperature and precipitation data for any point in Wyoming from 1895 to 2010.  These data are returned to a user in a separate browser window in a CSV format that can be copied to a user-preferred database or spreadsheet.

• Wyoming Water and Climate Map Server
  Known as the Wyoming Water and Climate Map Server (WCMS), this online web-mapping system brings together real-time observations and summary products from multiple federal agencies (NOAA-NWS, NRCS, USGS) to provide "one-stop-shopping" for key water datasets. Likewise this system is providing a platform for data delivery, archiving, and QC/QA for a new statewide hydroclimatic monitoring network.
• Powder River Basin IMS Web Mapping Site
  The primary objective of this web-mapping portal is to relate water quality analyses from water, oil, gas, and coalbed methane wells to specific coal beds or geologic formations in the Powder River Basin, Wyoming. The project will enable developers, water users, or regulators to more effectively estimate the quality of water before it is produced.

1. Be sure to disable popup blockers or at least allow popups from .wrds.uwyo.edu before accessing the Map Server. Please check the documentation of your specific blocker for how to accomplish this. Not all layers are visible at all scales. Most layers are not visible when zoomed in closer than 1:24000 scale. Many layers are also not visible at the statewide scale, either. Be sure to zoom in to a general area of interest before turning on layers. If a layer is not visible at your current zoom level, the box next to it will be indicated with the following symbol
2. Please note that the first time the map is accessed, it may take 15-20 seconds to draw.
3. First time users are encouraged to read the HELP menu, located to the right of the screen, before using the IMS application.
4. Please be aware that certain browser toolbar buttons, ie refresh, back and forward, will not work with this application. You will need to use the IMS application tools to perform these tasks.
5. While WRDS strives to make this IMS application available at all times, please be aware that the application can be down at times for upgrades and data maintenance.
6. The IMS application will work with current dailup speeds, however the user should be aware that certain functions and drawing times will take longer. Please be patient. Application performance can be increased through the use of broadband access available from local telecommunication providers.
