Thanks for filling in the details on that Jeff, since we're not using the Map application I forgot all about it. Losing the ability to use this app is a definite downside to using Geoserver, however we have found with the numerous other ways to access the data it has not been a major problem for our use. It would be great to see a Geoserver option for Hydroserver map in the future though!

Francesco,

I think you have gotten good advise here from Tim and Piper. Tim and Piper – thanks for responding.

Generally – there are two functions served by ArcGIS Server for the HydroServer software stack. The first is publishing geospatial data as web services, which can easily be done using GeoServer (as Piper Describes). The second is that we built the HydroServer Map application using the ArcGIS Server Application Developer Framework. This is a component of ArcGIS Server that is used to create maps within web applications. Unfortunately, that application won't work without the component and so if you do not have ArcGIS Server, you can't use that application. But, that doesn't affect the rest of the HydroServer software stack. There are links to the map application from the HydroServer website, but they can easily be removed if you are not using it.

We are having a critical look at the HydroServer Map Application right now given that we used ArcGIS Server 9.3.1 to build the tool, and ESRI is now up to 10.1. It is due for an update, and we will consider alternatives.

Subject: Re: HydroServer without ArcGIS server

Hi Francesco,

We use Geoserver as our WMS here at the NPCA. The only real impact this has had on our CUAHSI implementation was adding notes to inform users of our WMS locations, and the need to customize the map elements on the Hydroserver website. This was fairly trivial if you have javascript skills. It requires the use of OpenLayers which is installed with Geoserver.
You can see an example of the maps customization by viewing the page source here: http://www.his.npca.ca/hydroserver/GIS-Data/1

The biggest effort for our implementation was getting Geoserver running on an IIS server. In case you are faced with the same challenge, I have attached some documentation. Basically, we first had to install Apache Tomcat server on our IIS machine, then install Geoserver within the Tomcat container. This work was done in 2010 and we plan to upgrade both Tomcat and Geoserver this year, you would be well advised to investigate the latest versions before following our documentation as things may be easier or different now.

I hope this helps you in your efforts,
Piper McKinnon

Dear All,
I'd like to know wheter it is possible to design a Hydroserver implementation that does not make use of (the expensive) ArcGIS server and instead uses another map server application in place of it.
I found something about the possibility of using GeoServer in these pages:
http://cuahsihis.blogspot.it/2012/11/what-is-hydroserver.html
http://hydroserver.codeplex.com/workitem/7113
but I didn't find anything more in depth about tecnical installation information.
Do you have either some experiences or further information about it?
Thank you

Sincerely

Francesco

New Post: ODM conversion

katmckee — Thu, 20 Dec 2012 15:58:29 GMT

Hello,

Can the conversion script from ODM 1.0 to 1.1 be put in downloads?

Can instructions for both conversions (1.0 and 1.1 to 1.1.1) be put in documentation?

thanks,

New Post: ODM Tools: Editing Existing Data Series ERROR

erna — Tue, 09 Oct 2012 13:33:54 GMT

Hello,

I successfully installed ODM Tools 1.1.3.2. I can querying and visualizing the data series. But something went wrong with the editing tool. The first step to creating a quality controlled data series from the row data series is to create entirely data series from data series that are already stored in the database. After the new window 'Derive New Data Series' opened and I selected the radio Buttons "Create a Quality Controlled Data Series for Editing" and “Automatically generate a Method Description” and the new Quality control Level the derive new data series was not successful. The following error message appear:

Unable to update the DataValues Table with the values for the new Data Series: Cannot Continue!!

Unable to create the Values for this Data Series: Cannot Continue!

Thanks for your help,

Erna

New Post: Error in deploying WaterOneFlow

coolkids1988918 — Tue, 17 Apr 2012 13:44:06 GMT

Well, when I deployed WaterOneFlow of current release following the document, I got the error that

in this line '<compilation debug="false" targetFramework="4.0" />', the 'targetFramework' property couldn't be recognized.

So I wonder how this problem cause and how to solve it.

New Post: Discover geospatial datasets / Geoserver instead of Arcserver

AnjaC — Sat, 03 Dec 2011 19:46:13 GMT

Hi everybody,

As far as I understand HydroServer currently doesn't offer the possibility to discover geospatial datasets, I was wondering if there are plans to change this behaviour in the future? In our department we are also interested in downloading extra metadata (documents and tables) related to specific sites.

Another question is if there is any experience in using Geoserver instead of Arcserver for the web mapping services?

Thanks for the information!
Anja

New Post: WaterOneFlow and Apache Server

jncole — Thu, 01 Dec 2011 01:11:53 GMT

Hello and thanks for the quick reply. I misspoke earlier, I meant apache tomcat in my first post. Thanks for offering to temporarily host my service, that's very kind of you. What would that entail?

If I read the setup guide correctly, IIS and the SQL server can be on separate servers. I'm now thinking that it would be possible to setup up a VM running Win 2008, IIS, and WaterOneFlow and hosting the web services there while I rebuild my HydroServer.

New Post: ODM design for Variables, Time support

katmckee — Mon, 26 Sep 2011 14:07:25 GMT

I have a database

SFE_CTDsondes to track a network of sondes we have in a basin. Some sondes are in groundwater, some are in surfacewater. Some have QC = 0, some have QC = 1. Some data points are 15 minute, some are hourly. I have to create multiple variables for specific conductivity. Then when I use ODM tools or Hydroexcel, these datasets are all separated and not viewable togehter on a graph without doing programming:

GWSpec_Cond_Hourly

GWSpec_Cond_15

SWSpec_Cond_Hourly

SWSpec_Cond_15

As a user in Hydrodesktop for example, I would like to choose Sites that are groundwater sites, then see all the Specific Conductivity. The variables table should not have to worry about wether the info is collected in GW or sW, 15 min or 30 min.

Maybe Sample Medium should be associated with a site record? is a groundwater site, or a surfacewater site?

New Post: ODM design for Variables, Time support

katmckee — Fri, 23 Sep 2011 20:48:07 GMT

This is an important discussion. Some of the tools use the data series stored in the database that DavidV refers to as designed for internal data needs. But the users are having to choose betweem and decipher these multiple dataseries and it is a barrier for data analysis and tool usage. ODM Tools and HydroExcel use these data stored in multiple variables with different time support, e.g., and users must know to look for multiple variable codes and data series for what are the actually the same variables (as the scientific community defines the word variable). I am happy this is being considered as part of the next ODM revision.

New Post: ODM design for Variables, Time support

valentinedwv — Thu, 08 Sep 2011 21:32:20 GMT

Translation: Data management needs are different that data analysis needs. Internal data needs are different that external datasets (raw vs processed and quality controlled).

Kat's thoughts better match the management of data done by Kisters and the USGS. Observations are associated with a sensor at a location, and different processing creates additional streams/series. In the USGS, the same "variable" say 00060 means the same thing across all datasoruces: real time, Daily, and sproadic. In fact, the real time sampling rate of a station may change if they are trying to capture an event.

Kathleen,

I believe that this is part of a bigger question. I believe that measurement time series and analysis time series are not the same thing. The current design of ODM has only one type of time series that is used for both purposes, and we have foreced it to fit to both purposes. As we analyze the data needs of the community as part of revising ODM, I believe that some way of managing measurement metadata such as time support is needed seperately from the analysis groupings. Kathleen's issue is one example of this. Another example is evident with the vertical offsets. Here we sometimes have the opposite problem, where we would prefer to analyze data with different offsets seperately, even though the data points use the same variable. So, this is one of several issues that are being considered as part of the next ODM design revision.

New Post: ODM design for Variables, Time support

katmckee — Tue, 06 Sep 2011 20:32:27 GMT

In the ODM, a new variable must be defined if you change time support for your instrument.

We changed from 15 minute collection to hourly collection. this required that I defined a whole new varialbe for Specific Conductivity. This is problematic for outputs, graphs, reports, hydrodesktop, user training. It is actually the same variable, just collecting it less often.

I want to submit an official request to change odm in a future version so that time support is not part of the variable record. We want to graph the 15 minute data with 1 hourly data etc.

You should also consider removing the definition in the variable record of continuous vs. average. I would still want to graph averaged values with continuous values if I had both. This also should not be part of the variable record.

thank you!

New Post: How To Rename Database

katmckee — Fri, 02 Sep 2011 18:42:20 GMT

I am working on implementing HYdroserver website and Hydroserver capabilities database on my server. This gave me incentive to clean house, and have inventoried all the services/databases I have in SQLServer and have decided to delete a few and rename the rest.

I have created a table of all the services/databases including Db name, Network Vocab (as seen in HIS Central), DataSource string and new db name. indicator if it is a database I would like to delete.

Maybe I would have to

Rename the database in SQLServer
Rename each folder on the server in P:\wateroneflow
Open the IIS manager and rename/redirect the services there
1. Edit the Aliases for each
2. Change the Network name in each web service
3. vocabulary for each will remain = FLWI
Then go to HIS central and request a harvest?

Thanks for your help,

Kathleen

New Post: Time Series Analyst and Map

coolkids1988918 — Sun, 03 Jul 2011 16:52:06 GMT

Well, I meet with two problems when I'm setting up the HydroServer.

One is for time series analyst of website. I use MS SQL Server 2008 Chinese edition, and the time format differs from in English, and this occured: "Error While Plotting Data: Error Occured in DatabaseFunctions.OpenTable Conversion failed when converting date and/or time from character string".

The other is for the map application. I use windows 7 32bit OS, ArcGIS 10 sp1 and I replaced the ArcGIS reference of 9.3.1 with the same reference of 10, then I use the ERSI's map service, and I got the NullReferenceException in line 99

"Dim MapSR As ADF.Web.SpatialReference.IDSpatialReferenceInfo = Map1.SpatialReference.CoordinateSystem",

and VS2010 points that "SpatialReference" on the right refers to "Null".

New Post: TSA: DatabaseFunctions.GetConnectionString Index was out of range

prokein — Tue, 11 May 2010 05:22:02 GMT

Thanks to Jeff for pointing out that this error occurs when the HydroServerCapabilities database has not been populated yet.

Once the HydroServerCapabilities database has been populated with at the very least content under the ODM Databases option the above shown error will disappear and data will be properly displayed.

New Post: TSA: DatabaseFunctions.GetConnectionString Index was out of range

prokein — Tue, 11 May 2010 03:33:20 GMT

Not sure what's happening, I think I followed the setup instructions precicely but I am running into the following error using the Time Series Analyst:

Error Occured in Default.Page_LoadComplete
Error Occured in DatabaseFunctions.OpenTable
Error Occured in DatabaseFunctions.GetConnectionString Index was out of range.
Must be non-negative and less than the size of the collection. Parameter name: index

Here's a screenshot of the page as I see it:

Not entirely sure where I should start looking to troubleshoot this. It looks like it can't connect to the OD database. The TSA application currently has one connection string to the HydroServerCapabilities database. I confirmed that the read-only user I created works properly by using the read-only user credentials in ODM Tools running on the local machine and the connection was made just fine.

Windows 2008 R2 Standard, IIS7, .Net 3.5.1
