    Hi Tobias,

    Are you sure it’s Mapper++ and not Mapper Classic? Either way, the mappers do not do any kind of data conversion. All they do is read the data so if you are reading a time to one ft, it will be 1ft or 0.3048m or time to 2ft or 0.6096m.

    Hi Eric,

    I think if you plot the max water surface elevation map, it includes the channel. Are you seeing a hole where you expect your channel to be.

    You can also get that plot in QGIS and in Profiles.

    Can you open the image in Lesson 1? If not, please run the patch. See Installation Problems first post on the forum.

    Hi Hamid, I do recommend that you use QGIS Plugin instead of GDS if you have problems building a *.pts file. Please try this update. It will give you a corrected GDS. There may have been a bug that wouldn’t read *.pts data.

    And a *.pts file is simply an ascii xyz file. You can build it with any program such as ArcGIS, ArcMap, QGIS, Global Mapper. It’s just a text file with the extension set to .pts.

    Gabriela,

    You might need to wait for it to complete or here is an update that might fix the issue.

    Hi Gabriela, I’m sorry about that. Here is that program.

    I probably don’t need to say this but you should copy your project to a new project folder before you do this interpolation so you don’t overwrite data you might need.

    Hi Eric,

    Sorry I missed your post. You can do this with the GDS but instead of importing the data, you can simply use the Interpolate from Multiple Files option. It will overwrite the old elevation data. If you only want to overwrite a specific area, select that area first with a polygon or shapefile. Your data will need to be in the xyz text file format with space delimiter.

    It looks like you are trying to run GDS from the download folder. The FLO-2D folder is installed to c:\program files(x86)\FLO-2D Pro

    Hi Fernando,

    Did you get help with this issue. I think I recall Noemi helping you with this.

    Hi fpcampomanes,

    I think your problem might be that your region limits. When you create your grid, extend the region limits so that you are absolutely sure the whole polygon is within the grid.

    Make sure there is only one polygon in the shapefile.

    It may be necessary to simplify the verticies of the shapefile. You could use a Simplify and limit the space between vertices to 5 ft 1.2 m or something like that. That will create less verticies to intersect to the grid.

    Our hydrograph data is pretty simple to create. Take a look at the *.hyd file from any example project. You will note some simple things from those.

    0 23.92
    0 0
    0.08 0
    0.17 0
    0.25 0
    0.33 0
    ….

    You get the start time end time
    Hydrograph pairs

    You can build them yourself using any filename and assign them using the in/out condition dialog box.

    They are space delimited so take out any tabs that might come from other programs. So if you want to get data from a RAS unsteady hydrograph, you can copy that data from the Data Tables or I think you can save that data to a text file. Just make sure you convert all tabs to spaces.

    Or Take a look at any inflow.dat file. You’ll see that they are also super easy to construct using a text editor or copy paste from Excel.

    They require a control line with a grid element and the inflow hydrograph in hours. Again, take out any spaces you see.

    Good question. Those values are pretty specific to Pima County so if you aren’t using the formulas exactly shown in the GDS manual, you will likely get an error. For example, if you are using a category that isn’t listed in the Pima County classifications, you’ll probably get an error. I suggest that you would be better off developing your own system using rasters or shapfiles and a field calculator to generate a shapefile that has only curve numbers.

    FLO-2D Basic does have limitations. The error message you are receiving is correct, cell size limit is 100×100 and grid element is 50,000.
