M.Irfan thnx but I have failed to get "ESRI.APWR.ApRegWork.exe". Sorry, what issue are you having in downloading the ApRegWork folder with executables? [ATTACH=CONFIG]27942[/ATTACH] Secure ftp to the Esri Water Resources download site. Revised log-in details here. Change directory --> Incomming --> ApRegWork and download contents of directory.  Run ESRI.APWR.ApRegWork.exe from downloaded location. Stuart ... View more

Beverly, Suggest you select a project appropriate projected coordinate system--California State Plane Zone 2, or UTM Zone 10--and import the decimal degree shape files into File Geodatabase feature classes in that projection. Stuart ... View more

Beverly, Since in your other post you mention you are starting from shape files, would first suggest that you migrate your river reach data out of Shape Files and into a proper File Geodatabase. You may find that one of the NHD data sets already has your reach of the Sacremento already delineated. Anyhow, you need to select a projected coordinate system California State Plane Zone 2, or UTM Zone 10 and import the decimal degree shape files into feature classes in that projection. Then you'll want to prepare your route (the linear referenced reaches) and events (sampling stations, gauges, etc.) along the routes. Pretty well explained in these and related help resources: http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/Designing_a_linear_referencing_system_in_your_geodatabase/003900000007000000/ http://resources.arcgis.com/en/help/main/10.1/index.html#//003900000001000000 http://resources.arcgis.com/en/help/main/10.1/index.html#//003m00000005000000 Stuart p.s moving this to the Hydro forum from the Geodatabase and ArcSDE as more likely to provide you with useable assistance. ...

Koabi, No need to reinstall the ArcGIS 10.1 license manager just to service CityEngine seats. Believe that the CityEngine 2012.1 concurrent use license fulfillments on the ArcGIS 10.2 License Manager will work without issue if on conclusion of a fresh CityEngine installation you do not run the "authorize now". Rather, you can avoid problems by directly creating the correct concurrent License configuration in each user's home directory. Format for the esriLicense.config file to write into each user accounts home directory: CITYENGINE_CONFIG=TRUE SOFTWARE_CLASS_CITYENGINE=Advanced SEAT_PREFERENCE_CITYENGINE=Float LICENSE_SERVER=port@FQDN (or @IP) Stuart ...

Was the password recently reset? No changes, as I was just able to connect and transfer data a moment ago.  A temporary connectivity outage for you? Stuart ... View more

Teresa, Where can I find the new version of Arc Hydro tools that are compatible with ArcGIS 10.2 ? Open the secure ftp site as in this thread, and navigate to: /incoming/ArcHydro/Setup10.2 Stuart ... View more

@Esri Water Resources Team, Installed ArcHydro 10.2.0.6  for ArcGIS 10.2 using the 64-bit geoprocessing based build. Clean install with nothing amiss on review of a verbose install log. Cursory testing has everything functioning as expected. Thanks! Stuart ... View more

Cindy, %APPDATA% environment variable depends on your operating system: XP and prior  -->  C:\Documents and Settings\<username>\AppData\Roaming Vista and newer --> C:\Users\<username>\AppData\Roaming    (hidden by default in Windows Explorer, but its there) Always can confirm by entering "echo %APPDATA%" from a command window (cmd.exe) Stuart ...

Jessie, It sounds as if you are working with AHPS archive data -- specifically the Observed, Yearly Archive, Shapefiles format data.  http://water.weather.gov/precip/download.php The 2005 yearly archive download would be nws_precip_year2date_observed_shape_20060101.tar.gz  and extract to nws_precip_year2date_observed_20060101.shp (with helper files) Those shapefiles are derived from consolidated RFC XMRG formated records and are already projected for you into a HRAP compliant Spherical North Polar Stereographic including a usable .PRJ projection file.  It has the correct spherical radius but not the control latitude for HRAP--not critical as the grids are fixed and geographic coordinates already calculated for you--correctly we'll presume.  If you look in the Shapefile attribute table for one of the yearly precipitation observed archives, you'll see that in addition to the calculated Lat/Long for the HRAP grid center point you have the actual HRAP grid cell reference for the value.  In short you already have the cell values that an actual XMRG StageIII or MPE value report would provide, the grid cells and values that would be extracted by parsing the XMRG's Run Length Encoding.  Also, the shapefile point is positioned at the  center of the HRAP grid converted from grid Meters to Lat/Long.  In other words you do not have to export or manipulate them beyond handling, or not handling, the transform between spherical coordinates and the ITRS/GRS-80 ellipsoid used in Albers Equal Area. So, you could  1) work backward and reconstruct the HRAP grid, and include reference lattitude of 60 deg and grid length, and then use that to resample from nominal 4K HRAP grids (i.e. 4762.5m at 60 deg north) into a denser, or sparser, raster then projected into Albers Equal Area Conic--review the Reed & Maidment article.  Or, 2)  you can project the GCS shapefile center points and value into Albers Eaqual Area Conic, not as precise,  and interpolate that regular grid into a precipitation surface, and intersect county features against that statistical surface.  Or, 3) what is probably simplest just use the HRAP spherical GCS center point and value, and convert directly from feature to raster--but set the cell size against the full range of the AHPS HRAP data set--(found  http://water.weather.gov/precip/p_download_new/nws_precip_allpoint.tar.gz  ) which would let you normalize the raster across the data sets (yearly, monthly daily), and then project that to Albers Equal Area Conic and  intersect that raster with county features. Here is the 2005 yearly file with option 3, on HRAP sphere as GCS, and then Albers Equal Area [ATTACH=CONFIG]26483[/ATTACH] [ATTACH=CONFIG]26480[/ATTACH] [ATTACH=CONFIG]26481[/ATTACH] Stuart ...

Bradley, Asked, and received a note back from Christine D., they are working on it already... "You need a specific installation package for 10.2. We created one so far using the same code base and found some issues (so far raster processing was ok but we need some code changes for some of the raster to vector and vectors function (e.g. catchment))... it is not ready yet." So keep an eye out in this forum, you'll know about it pretty quickly once released to the sftp site. Stuart ... View more

Jessica, HRAP, cast on the National Weather Service (NWS) 1/40th Limited Fine Mesh, is gridded system used to encode WSR-88D NEXRAD Level II Radar Product Generator (RPG) Precipitation Processing System (PPS) and current Multi-Sensor Precipitation Estimator (MPE) precipitation reporting for each NEXRAD station, and it also is used by the NWS - River Forcast Centers (RFC) for Stage III, now MPE, mosaic precipitation reporting.  HRAP grid is a projected in polar stereographic with the North pole arbitrarily assigned Grid cell (4330, 4330), each NEXRAD station is positioned into the same grid, but the RPG generates reports into a 131 x 131 array of HRAP grid cells with the radar located in the local (66,66) cell for its reports. The RFC's mosaic each RPG output back to its correct HRAP location and issue Stage III or MPE summaries in full HRAP for their respective reporting areas. That is each NEXRAD site has a reporting grid (fixed at 131x131 cells) and each RFC has a reporting grid (fixed to its reporting area), and also the NWS mosaics input from the RPGs/RFCs into a full CONUS map based all based on HRAP grid, nominal 4km grid. The HRAP 1/40th Limited Fine Mesh is defined like this.    North Pole Stereographic    Lattitude of origin 90.00    Longitude -105.00    Reference Lattitude 60.00    Earth radius 6371200.000 m    grid cell size 4762.5 m (nominal, actual inscribed length varies with lattitude) While the NEXRAD radars operate in local polar radial segments and distance bins, HRAP provides an efficient run length encoded mechanism for delivering converted Radar Product Generator radial bin data as compressed Level III grid data reporting--Hourly Digital Precipitation (HDP), Three Hour Precipitation (THP), or Storm Total Precipitation (STP) arrays. But since xmrg Level III and Stage III/MPE reporting is encoded lowerleft to upper right, it also has to be inverted to load as Esri Grid, done by reversing the read order if you do obtain XMRG (RPG level III/MPE or RFC Stage III/MPE). Also byte order conversion between big-endian (NWS AWIPS HP Workstations) and little-endian (Intel Linux & Windows OSs) formats is required for some of the older XMRG data. Obtain and have a read of the S. Reed & D. Maidment (April 1999) article Coordinate Transformations for Using NEXRAD Data in GIS-Based Hydrologic Modeling from the Journal of Hydrological Engineering, Volume 4 issue 2, pg 174-182. It will give you an better idea of how to visualize HRAP grid laid over the Polar projection.  This is fig 4. from the article (but I've marked it to show the 1/40 LFM values, North pole would be at 4330,4330): [ATTACH=CONFIG]26298[/ATTACH] It can be a little confusing, especially if you have to unwind the Run Length Encoding of archival the RPG Level II/III, or RFC StageIII/MPE data.  And now, with faster network connections, the HRAP grid based data exchange is being replaced with more real time RPG Level II distribution via the UCAR Internet Data Distribution digital interchange. If interested in that visit the Unidata folks at http://www.unidata.ucar.edu/data/#levelII Good luck. Stuart ... View more

Andrea, Do you have ArcGIS Desktop 9.3, or 9.3.1? The ArcHydroTools9.msi installer (build 1.4.0.258, Jan 9 2013) on the secure download site will install and run for either release of ArcGIS. Once you install, the ArcHydro Tools Help article will take you through the map algebra processes ArcHydro Tools perform for conditioning the DEM (filling sinks), and identifying flow direction, flow accumulation, stream network and/or basin,  and finally raster to feature conversion. Also, the ArcGIS 9.3/9.3.1 Spatial Analyst help, has some guidance. But is a bit disjointed and out of sequence compared to the Help presentation in ArcHydro Tools, and be sure to review the "Learn more about..." Help panels as well. It will work, but the data handling is a bit more demanding when using Spatial Analyst extension compared to ArcHydro Tools. Post back if still stuck. Stuart ... View more
