    Tool Failures

    Hi Simone, You should be able to run the Rasters To GeoVolumes tool in batch mode. I have tested this for a set of TINs and rasters and it seems to work fine. Also, am not encountering the crash you mentioned. If this is still an issue please let us know. Thanks, Gil
  2. Hi Simone, See below some suggestions: Regarding the closed volumes – we have also found that in some cases the features created are not closed which means you cannot calculate their volume. We are still trying to figure this out and are going back and forth with ESRI’s 3D team. We do not have a solution at this point, but I have a few suggestions you can try. The spacing and smoothness of the TIN is a factor – you can try to smooth/simplify the boundary polygon before creating the TIN. Create the TIN with a larger spacing - the denser the points (more detailed TIN) you have more chance to run into issues with the volume. Increase the minimum thickness parameter in the Rasters to GeoVolumes tool. Using a single TIN for multiple boundaries: Your approach of using a single TIN for multiple raster boundaries can work however there are some complications here: If you are using a single GeoRasters raster catalog to store the rasters then you need to specify for each run which of the rasters should be used. It won’t make sense to run the Rasters To GeoVolumes tool for all rasters at once as the tool looks for horizon ids and then fills between them. A workaround would be to use the Definition Query to filter the GeoRasters you want to use for each run. I tested this and it works nicely. Using the Definition query on the raster catalog you can specify each time the rasters you want to use and then run the Rasters To GeoVolumes tool only on those rasters. In this manner you are using a single TIN, but the rasters change every run. Should be fairly easy to write a small python script that modifies the Definition Query on the GeoRasters and then runs the Raster To GeoVolumes tool. This way you would be able to create a list of runs and execute them using a script. Creating multiple TINs: Another option is to create a TIN for each zone/lens you want to calculate. You can do the following: Batch the Tin to Polygon tool to create a set of TINs. Notice that you will need to have each boundary polygon in a separate feature class as the tool doesn’t work on multiple polygons in a single feature class. Batch the Rasters To GeoVolumes tool to work on the set of TINS created in the previous step. This doesn’t really solve your initial problem as you will still need to edit/filter the raster catalog each time you want to run the tool. Thus, probably the easiest way is to have the single tin and apply the Definition Query as mentioned above.
  3. Hi Fang, We identified the problem and fixed the tool. this fix will be available in the next release. Thanks for reporting this. Gil
  4. Hi, The MODFLOW Data Model (MDM) is documented here: http://www.archydrogw.com/ahgw/MODFLOW_Data_Model Gil
  5. Hi Fang, I was able to replicate this problem and we are looking into it. Will post something once we are able to identify a solution. Thanks, Gil

    adding toolbar

    Hi, I am not sure what the problem is. Are you able to run the Geoprocessing tools? In any case you should not be adding the toolbar from the DLL. Please contact Technial Support: http://www.aquaveo.com/technical-support. They will try to help you in more detail. Best regards, Gil

    Hi, You can try using the following to uninstall: http://support.microsoft.com/mats/Program_Install_and_Uninstall. Gil
  8. A tutorial on handling Time Series related with Wells is available at the Arc Hydro Groundwater Learning Center: http://www.aquaveo.com/ahgw-learning. This tutorial describes a process of taking measurements, calculating statistics, and interpolating surfaces representing water levels (or water quality). A number of users have asked about automating this process. The following python script helps create a workflow to automate the production of water level and water quality maps. The workflow includes the following steps: Use the Create Time Series Statistics to calculate statistics for a specified time frame (e.g. average water level for a time period). Interpolate a raster from the summary statistics to represent a continuous surface over a defined area (e.g. county). Add the raster to a RasterSeries catalog with its time indexes (this helps you manage the raster sand animate them). To use the script just copy over the python file and toolbox file to the same directory. if you want to use the model available in the toolbox you will need to Edit the model and specify the input parameters to match your data. You can batch the model/script to create a set of rasters for different time periods. example script and toolbox.zip

    adding toolbar

    Hi, You need to install the tools by getting the installer from the Aquaveo website:http://www.aquaveo.com/downloads?tab=0#TabbedPanels Uninstall any of the Arc Hydro Groundwater tools you have on your machine. Run the instalation and then register the product. You cannot simply copy the DLLs from a different machine and try to load the tools. Hope this helps. Gil

    adding toolbar

    Hi, You cannot add the toolbar by just browsing to the DLL. The DLL has to be registered by running the installer. Once you run the installer you should be able to select Customize -> Toolbars -> Arc Hydro Groundwater Toolbar to add the toolbar to the map. Did you install the tools before trying to add the toolbar to the map? Best regards, Gil
  11. The Arc Hydro Groundwater toolbox is located in the System Toolbox. You can add the toolbox by Selecting the Add Toolbox option and browsing to the System Toolboxes. Once you loaded the toolbox into ArcMap or ArcScene you can right click anywhere in the Arc Toolbox window and select the option to Save Setting -> To Default. Now anytime you open ArcMap or ArcScene the Arc Hydro Groundwater toolbox will be available in your Arc Toolbox window.
  12. Hi Simon, We are aware of this issue but have not yet been able to resolve it. For now, I think the best approach is to export the model you created to a python script that with minor edits would enable you to batch the process. Attached is an example model you can use as your base. You will probably need some minor edits to make sure the paths in the model point to the right location on your computer. You can run the script in batch mode from the attached toolbox in Arc Map. Let us know if you have any questions. Best regards, Gil water level map script example.zip
  13. Hi, Yes, you will need to have ArcGIS 10 to do the volume calculation. In ArcGIS 10 there is a new toolset as part of 3D Analyst named 3D Features, in there you have different tools for 3D operations. The Add Z Information tool will allow you to calculate a volume on a multipatch. Gil
  14. You can set the grid on a data frame using the Set Layer As Map Grid tool available on the AHGW toolbar (). The tool lets you select the feature classes and the grid value attributes (). You can also set the grid in the data frame properties, but the tool automates this. Gil
  15. This is part of a separate post by Simon: "when i try to pull say one cross section into a new map im not able to use or set up a customized grid where the major and minor grid line shape files are able to create the grid, it automatically does this for me when i create the cross section in the fist instance. Is this likely to be an issue with my extensions or something."
  16. Hi, Regarding the first topic - i don't think the problem is because you are using 9.3. looks like the tool is not able to read values from the DEM raster. Make sure that the raster is projected in the same coordinate system as the section lines and outcrop polygons. Also make sure you are using an appropriate discretization distance. If you check both of these and are still having a problem, please send me the map + geodatabase + raster and i will take a look. Regarding the grid lines - i opened a separate post for this: http://aquaveo.invisionzone.com/index.php?showtopic=1335 Please feel free to ask as many questions as necessary. We learn a lot from our users. Gil
  17. Hi, Are you getting a line in the XS2D data frame, but it is flat? Not sure I understand the issue. If you can send some more details that will be helpful. A figure showing the result/error would be good. Thanks, Gil
  18. Hi, You need to first create a new feature class that is referenced in the XS2D Catalog table. The drop down list you refer to is created from the catalog table. There is a tool for this named Create XS2D Line Feature Class that is located in the XS2D Editor toolset. You can take a look at the tutorial named Creating 2D Cross Sections, look for the section named "Adding Data From Geologic Maps" it includes a detailed description of the process. Gil
  19. From looking at your data, the problem was that the domain defined for the feature dataset was too small. Especially the Min Y that was 1900. Gil
  20. The easting/northing attributes of the bores shouldn’t matter. The XS2D Wizard uses the coordinates from the geometries of the bores and not from the attributes. If the bores appear in the right location on the map and everything is in the right projection (if you put the section lines and bores in the same feature dataset and make sure the projection is correct you shouldn’t have any problem with this) then the wizard should work fine. If you want the easting/northing values to be added to the bores as attributes you need to create fields for them in the Bore feature class and match these fields in the import process. Gil
  21. Make sure to assign a HydroID to your section line, if the HydroID is Null the Wizard will not execute (this will be fixed to give an error message in the next release of the Arc Hydro Groundwater tools).
  22. Hi Dan, Currently the tool will only process a cross section if it is within the extent of all rasters specified in the raster catalog. So the limit is the raster with the smallest extent. However you can "trick" the tool to process all cross sections by changing the selected features in the section line feature class and changing the clip/fill values in the GeoRasters raster catalog. Here is an example: We have 3 rasters where the top raster has a smaller extent than the two other rasteras shown in Figure 1. also notice there are 3 section lines and one of the section lines extends beyond the extent of the smaller raster. If we run the tool for all 3 section lines we will only get GeoSection features for the section lines that are within the extent of the smaller raster, as shown in Figure 2. To create GeoSections for the section line that extends beyond the extent of the top raster we can disable that raster by going into the GeoRasters raster catalog and setting the clip and fill attributes to 0 (as shown in Figure 3). When setting the values to 0 the tool will ignore this raster in the filling process. The final step will be to select only the section line that we want to process and rerun the Raster To GeoSections tool (make sure that the append option is active so you don't overwrite the GeoSections already created). The tool will only run on the selected section lines and will create the GeoSection features for that cross section. The only drawback is that there will be no GeoSection feature created for the top raster as it was disabled from the process. The final results are shown in Figure 4. Gil
  23. Hi Adam, All the tutorials are also available on the Arc Hydro Groundwater Learning Center: http://www.aquaveo.com/ahgw-learning So you don't need to get all the tutorials if you are interested only in a specific one. Gil
  24. When creating a new Arc Hydro Groundwater (AHGW) geodatabase using the GP tools users do not have control over the XY and Z domain extents. One of our users from Brazil has found a way to set the coordinate systems and still maintain control of setting the extent of the domain: Create a blank Arc Hydro Groundwater (AHGW) geodatabase with no spatial reference set. Using Arc Catalog define the spatial reference for the feature datasets - during the process of defining the spatial reference you can modify the Min and Max domain values (XY and Z) so the spatial reference can contain your 3D data. Load data and apply the AHGW tools to create features.
  25. When creating 3D features using the Arc Hydro Groundwater tools it is important to define your coordinate systems correctly. A few common mistakes that lead to errors in applying the tools are: The vertical coordinate system is not defined. The vertical coordinate system is defined incorrectly. A few examples are: Tools creating 3D features require that your XY coordinate system is a projected coordinate system. The tools will not work with data defined in geographic coordinate systems as the vertical information cannot be defined in geographic coordinates. The vertical coordinate system units should match the units of the XY coordinate system. For example if you are using a projection with units of meters your vertical units should be defined in meters as well. The vertical coordinate system units do not match the units for of the data. If you have borehole data with depth defined in feet you need your vertical coordinate system to be in feet. If your XY coordinate system is in meters you should either project the data into feet or convert the vertical data to meters. [*]If you are using the XS2D component make sure that your domain is large enough: When creating cross sections the coordinates will start at 0 or even at a negative value (because the cross section coordinates are defined along the section line). So you need to make sure that Min and Max X are defined such that cross sections can be created. Remember to account for the vertical exaggeration. If you apply a vertical exaggeration of 20 you need to make sure that the Min and Max Y values are defined to support creating features with the exaggeration applied. Remember that you need to define the domain when creating the feature dataset where your feature classes will be created. Once the feature dataset is created you cannot modify the domain. If you want to check the domain values before creating the feature dataset uncheck the Accept default resolution and domain extent option (this is part of the process when creating a new feature dataset in ArcCatalog). You will then go through an interface that allows you to define the Min and Maz Z values. Another option to control the Z coordinate system is to use the Create Feature Dataset GP tool. When using this tool you have the option to specify Min and Maz Z values for your feature dataset. Under the Environments -> Geodatabase Settings you have the option to define the Z domain.
