Louisiana Department of Transportation and Development Data Sources for use in WMS

Data Sources

The primary gateway to accessing data for WMS can be found at: http://www.xmswiki.com/ and then go to the GeoSpatial Data Acquisition Page http://www.xmswiki.com/xms/GSDA:GSDA Some of the primary locations there are:

DEMS: http://nationalmap.gov/viewer.html

LandUse: http://www.webgis.com/

Soils: http://websoilsurvey.nrcs.usda.gov/

Aquaveo: http://www.aquaveo.com/

The LSU site can also be helpful, especially for DRG Images of USGS Maps. To download and use these maps:

  1. Go the site: http://atlas.lsu.edu/
  2. Choose Download Data
  3. Choose the map scale such as http://atlas.lsu.edu/q24k/ Scanned Topographic Maps
  4. Use the map to navigate to the area to be utilized.
  5. Select the map
  6. Choose the Download button
  7. Unzip the map on the computer
  8. Open WMS
  9. Right Click in the Project Explorer of WMS
  10. Choose Preferences
  11. Change the Image options to Always Convert Tiff and to Save the new JPG in the current directory.
  12. Open the image.
  13. The image is now in WMS. Repeat for other Quads as necessary.

Louisiana DOTD Models Using the NRCS (SCS) Method

Creating an NRCS (SCS) Project

  1. Using the WMS Wizard set the project coordinate system to UTM, NAD83, Zone 15
  2. With the Microsoft Virtual Earth Utility identify the study area – make sure it is “bigger” than the study area
  3. With Web Services download the DEM (10 meter cell size recommended) and Topo map (aerial photograph too if desired)
    1. Try to get the land use and soils data from the web services as well. They are currently on the Aquaveo server and there is not an intent to remove them but not a guarantee the will stay.
    2. Download the land use file(s) from http://www.webgis.com/
    3. Ask for the Ssurgo data and get an email with an ftp from: http://websoilsurvey.nrcs.usda.gov/
    4. Read these shapefiles into WMS and be sure they are converted to the UTM, NAD83, Zone 15 coordinate system

    2. In this load the standard LADOTD NRCS table (the current definition for Residential is for ¼ acre lots, some may want to adjust this value or any other as appropriate). This table can be downloaded here.
    3. Compute Basin Data and select the Lag Time – SCS equation.
  8. Set up the Job Control and Precipitation data for an HMS model if desired, but it is not necessary.
  9. Clean up the model.
    1. Turn off the Model Checker
  10. Exit the wizard and identify the data necessary to run the model.
  11. Go into the Display Options under Drainage and turn on the Maximum Flow Distance and Maximum Flow Slope.
  12. Save the WMS Project
  13. Use NOAA Atlas 14 or the LADOTD Hydraulics manual Figure 3.4-2 and Table 3.4-2 to get the desired rainfall depth.

Louisiana DOTD Models Using the USGS Method

USGS Project

  1. Using the WMS Wizard set the project coordinate system to UTM, NAD83, Zone 15
  2. With the Microsoft Virtual Earth Utility identify the study area – make sure it is "bigger" than the study area
  3. With Web Services download the DEM (1 arc Second recommended for larger areas) and Topo map (aerial photograph too if desired)
    1. If there are problems with the topo map, go to http://atlas.lsu.edu/ and navigate to download the DRG Files
    2. For the DEM, go to http://nationalmap.gov/viewer.html
    3. The Land Use and Soils files shouldn't be necessary for these projects because they do not require to compute CN, but if wanting to run HMS or something else then refer to the SCS document to process the land use and soils files
  4. Delineate the watershed
    1. Before delineating turn on the Create TC Coverage option
    2. Set the Accumulation Threshold to 1-3 sq. miles
  5. Clean up the model
    1. Turn off the Model Checker if desired
  6. Exit the wizard and identify the data necessary to run the model.
  7. Use the Maximum Flow Slope *5280 to get feet/mile
  8. Save the WMS Project.
  9. Open the Louisiana Mean Annual Rainfall .wms file file and determine the Mean Annual Rainfall.
  10. Run the model with the standard LADOTD program.
