I'm trying to recreate some network diagrams on a consistent basis based on our geometric network data. The layout algorithms I'm selecting are getting me close but I can't seem to fine tune the layout task to generate a consistent diagram with the desired layout. This is the approximate style I'm looking to recreate. The important part is the roughly even distribution of the links / branches. This is roughly what I have going (some of the time) when using the Schematic Editor. 1A / 1B: These are links that overlap that should not. 2: This is a link that need not extend to the right at all. It would great if it was just a straight link downwards. 3: This branch is an example of where better placement would be on the other side of the main line. I used a Composite algorithm of the following tasks: 1 - Orthogonal 2 - Relative - Main Line (using a line attribute) 3 - Geo - Rotate Nodes Along Links 4 - Separate Overlapping Links 5 - Square Links 6 - Bypass Nodes Anyone have a clue as how these tweaks can be achieved?

The build query achieves the same thing as my restriction does already. As I mentioned, the remaining roads are all valid routes. Pre-adding snapping distance as a cost doesn't solve the issue since the snapping distance is part of the total cost variable.

The purpose of the tool is to minimize / eliminate this type of decision making for the end user.

In designing a routing tool, I'm attempting to minimize the amount of surface streets (non-motorways) needed to reach the closest facilities. The only options available in Network Analyst are snap to closest feature or snap to first feature (within some tolerance radius) when using the AddLocations tool. As you can see from the image below, the code will snap the input location via part 1 every time (either by closest or by first). The favorable direction is to snap via path 2 to avoid that southern loop. Does anyone have any ideas of how to route using part 2? (Note: The Network dataset shown below is from OpenStreetMap and prohibits travel on motorways and motorway links. All the remaining roadways are to be treated equally in this scenario.)

According to ESRI documentation: "In geodatabases in Oracle and Informix, the XML columns use ArcSDE XML, which stores information as BLOBs in a series of separate tables. As such, they cannot be directly accessed with SQL." http://resources.arcgis.com/en/help/main/10.2/index.html#/A_quick_tour_of_geodatabase_system_tables/006z000000tr000000/ As such, the XML metadata cannot be accessed directly by a simple query to the database. (I tried to hunt for this as you have in the past.) I suggest using a Python script/Model to fully export the metadata. Use the XSLT Transformation tool and with an identity XSLT to extract all the metadata. You can save the code below as a XLST document to feed into the tool. See: http://www.usingxml.com/Transforms/XslIdentity <?xml version="1.0" ?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">  <xsl:template match="/ | @* | node()"> <xsl:copy> <xsl:apply-templates select="@* | node()" /> </xsl:copy> </xsl:template> </xsl:stylesheet>

Yeah, that was the idea. I have a duplicate of each layer and planned on using the context menu to turn it on/off to simulate the function in ArcMap.

I'm attempting to add a context menu to the TOC widget provided by nliu here: http://gmaps-utility-gis.googlecode.com/svn/tags/agsjs/2.09/src/agsjs/dijit/TOC.js I can get the context menu to appear however, it cannot see the data associated with the node. // (Within the PostCreate function) var pMenu; pMenu = new Menu({}); pMenu.addChild(new MenuItem({ label: "Turn On", onClick: this._manualTurnOn })); pMenu.startup(); pMenu.bindDomNode(this.rowNode); // (Reference - Code above was added before this section shown below) if (this.containerNode) { domStyle.set(this.containerNode, 'display', showChildren ? 'block' : 'none'); } I add a _manualTurnOn function and was hoping to interact with the serviceLayer using this context menu (as well as some other functions later). However, when the function is triggered, there doesn't appear to be any context of the TOCNode object that was used to create the node this Menu is associates. It's clear I'm misunderstanding how this widget is structured (possibly even how widgets actually work). Any clue how I might retrieve/interact with the underlying data associated with the node?

Some sample code or more detailed context might get more replies. In some previous code, I've tried to loop through and pull an extent from a group of points that happen to have the exact same coordinates and would throw a null object reference error because a graphic that consists of a single mappoint does not have a second dimension and thus no extent. Not sure if this applies to you or not.

If by basemap you are referring to your own map service, you'll need to provide a token in order for it to appear. Here's some documentation on how to acquire a token for use. http://resources.arcgis.com/en/help/main/10.1/index.html#/Acquiring_ArcGIS_tokens/0154000005rp000000/ If you're referring to tiled map service like Bing Maps or ArcGIS Online, this could be another reason. You may want to use a tool like Fiddler or HTTPFox to determine what the response/error is. Hope this helps you get started.

Have you considered using the asc2dssGrid tool directly? It's the command line tool that's included with HEC GeoHMS. An example: ASC2DSSGRID.exe INPUT="C:\inputTempGrid.asc" PATHNAME="/SHG/SCE/TEMPERATURE/01JAN2012:0600/1HOUR/OBS/" DSSFILE=" C:\tempOutput.dss" GRIDTYPE="SHG" DTYPE="INST-VAL" DUNITS="DEG F" You get more options than using the toolbar utility.

Nevermind. The javascript API library was not being accessed properly. Once that was fixed, that function was restored.

In the 1.0 version of Geoportal, I used to be able to search for all the posted metadata entries, check the " Apply action to the entire result set:" checkbox and apply the "Set as Approved" action on all the records. Now it doesn't work for Geoportal 1.2. It complains that there are no selected records, but all the records should automatically be selected when the check box is toggled. Anyone else experiencing this in version 1.2? (And before any suggests, we have over 1000+ layers that need to be published. So I would prefer not to sit there and approve 50 records at a time...)

You'll probably need to define the projection first using arcpy.DefineProjection_management http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//001700000077000000 Then re-project the data as you have now using the arcpy.Project_management tool.

The info you need should be retrievable using this REST method: http://help.arcgis.com/en/arcgisserver/10.0/apis/rest/layers.html

In testing Geoportal, we've published some metadata using the ArcCatalog Publish Client. After approving the uploaded metadata, we decided to delete the record of the metadata. In trying upload the metadata again (without changing anything), the Client says the metadata was successfully uploaded, but there is no record of it in the administration page. We've tried with a couple different layers and it appears Geoportal does not allow you to upload the same metadata more than once (or one with the same name.) Any thoughts on what's going on? Is this a bug?
