You can use GRASS in QGIS as described here. Just create a slope layer then, using the raster calculator, make a new layer of a range of acceptable slope angles. You can then run the r.cost and. r.drain tools as mentioned in the other post and then polygonise the r.drain output and you've got your road. Remember that when you run the r.drain tool that you ...

Although this was asked two years ago, I'd like to provide a more thorough answer to this question, as there are a lot of views on this topic and the technology in ArcGIS Online (AGOL) has not changed much in the last two years since the original post regarding Enabling Attachments for "Hosted" Feature Layers. Two of the options listed listed below will ...

If you don't have Visio for Diagramer- All of the other answers here breaks any joins. I found this to work well in my case: Export the schema for the whole db using Arccatalog (Export - XML) - I didnt export the data, schema only Use some online Pretty Print service to format the xml Open the XML file in a text editor and Reorder the fields as you like ...

As alexGIS already said, it would be easiest to create a replica between your SDE database and your local backup fileGDB Make sure that your SDE database is versioned and all feature classes have a GlobalID. If you want to work with a fileGDB check-in/ check-out replicas is the right choise: ...

This is the expected result - the getCapabilities request goes via the proxy as it could be prevented by the browser as a Cross Origin Request. As the tiles themselves are loaded as images these are permitted cross-origin and so don't need to be loaded via the proxy - this can't be forced by configuring the Javascript API. If you needed to force the tile ...

The accepted method did not work for me because my basemap layer wouldn't show up in the Input Features dropdown. I solved this by doing the following: At the View menu, choose Data Frame Options. At the Data Frame Tab look for "Clip Options" Choose Clip to shape Then click the Specify Shape button Then select the boundary layer as input Apply and the ...

You can't use linear units with the projection your data is using. The feature class you have is using a Geographic Coordinate System, which only use angular units like degrees and radians. You have to Project this feature class to a Projected Coordinate System, like State Plane coordinates, to be able to use linear units like meters. The Project tool is ...

I will also recommend a free tools developed by Jenness Enterprises It is just in case you need to use other shapes or point grids.

You can do this with both the Create Fishnet tool or the Grid Index Features tool. Create Fishnet is a bit more configurable, and can output either polygon or polyline. Both will allow you to set a width and height.

The Field Calculator is the wrong tool for the job for the summary portion. Either use the Summary Statistics tool to create a summary table that has the FID as the case field and join it to the original and calculate the value over or create a standalone Python script that uses cursors and a dictionary to do the sums and write the values. For the Python ...

So, I was working in both the ArcGis GUI and arcpy scripting and accidentally found somewhat of a hacky solution. I tried creating sessions and was looking to execute the script from within the GUI's python window. In experimenting there, I found that the session appeared in the same list as versions when connecting to the Oracle DB. So, if I connect to a ...

Ghetto method would be to add two copies of the shapefile, add a different label system for each, and then turn the dissolve on one up to 100%.

Think this would be a 2 process thing (in Arc anyways). Create an event theme (or run Make XY Event Layer) and then use the z and m values from the attribute fields in the resulting feature to populate the geometry values. I would do something in Python, but you could run "Feature To 3D By Attribute". I'm not sure what an m value represents in your point ...

So it's actually very simple, as suggested by @FelixIP: Spatial join one to many in ModelBuilder, then export the resulting table to excel and create a pivot table to summarise values of the B polygons.

You can use the label expression builder to create a label that incorporates any field of the feature. See the link provided or search labeling tag for examples

Since it hasn't been mentioned so far and it seems to be the right tool for exactly what you are trying to achieve: Aggregate Polygons Set the minimum_hole_size to the minimum size of a polygon hole you want to keep. Smaller ones will be eliminated. PS. The optional minimum_area value in the same tool does the same for the polygon parts that are not ...

Aggregate polygons tool is probably what you want? It can join polygons within the same layer based upon a defined distance tolerance. You can also set minimum size of polygons and holes to retain.

Thank you for your valuable input. I took into account all your suggestions but I am not able to get the desired result when I want to create a buffer for 1000's of points. 1) SO for the table, as you had suggested create external table enodebuffer1 (EnodeBStatus string,shape binary) ROW FORMAT SERDE 'com.esri.hadoop.hive.serde.JsonSerde' STORED AS ...

ArcGIS doesn't handle HDF files very well, so you might need to use some other methods to extract the data. You could use the MODIS Reprojection Tool, or if you have access to ENVI/IDL, you can use them to read and export the data.

This is an issue with using the Enclosed JSON option when running JSON to Features. When this option is selected, the entire file is read into memory (json_fc = json.load(json_file)). You will want to use the Unenclosed JSON option, which means that you will also need to create your Hive table using the UnenclosedJsonInputFormat. For Example: CREATE ...

Also, an easy way is to use Reclassify tool where you should click the button Classify and change the number of classes to 1. Click Ok. Now, the output raster can be easily converted using Raster to Polygon conversion Tool. ;)

If you're working on an arcgis engine app then check your licence initializer change bindingarcgisruntime method the below code void BindingArcGISRuntime(object sender, EventArgs e) { // // TODO: Modify ArcGIS runtime binding code as needed // if (!RuntimeManager.Bind(ProductCode.Engine)) { ...

This is a slightly different way of doing this, but you can do this with the ArcGIS Maps for Office add-in. I downloaded some crime stats and made a map out of it very quickly:

Obviously this answer comes too late... maybe. I had exactly the same problem due to updates I made to bus routes using the "Reshape Feature" Tool. Dissolve, Merge and Unsplit were not working because the multipart features were not coincident. If you haven't noticed this by now, take a closer look at the vertices that must coincide between your multipart ...

Try using arcpy to back up your geodatabases. Example: workspace = r"workspace\file\path" arcpy.env.workspace = workspace print "Set Workspace" backup_location = r"new\folder\path" + "\\" + "workspace.gdb" print "Backing up workspace" arcpy.Copy_management(workspace, backup_location) print "Clearing Workspace cache" arcpy.env.workspace = "" ...

I am posting this just so you can mark this format as the answer. The IN syntax is the most compact way to write the expression you want: [OU] IN ('001', '002') AND [Formation] = 'Residuum'

I know this is an older post but I had a similar problem and found this tool http://www.arcgis.com/home/item.html?id=1dd4a6832b3d40b494dbf8521cc5134c, was the easiest solution. Hope this helps!

There appear to be no other postings about AnswerWorks either here or at GeoNet, and so I think your best option will be to post an ArcGIS Idea to have the ArcGIS Help enhanced to support partial word searches.

For the record: Enterprise geodatabase libraries were available for both 32-bit and 64-bit servers at 10.0, and have shipped exclusively 64-bit since ArcGIS 10.1. There has never been a "32-bit bottleneck" in ArcSDE client applications (as of the time of the original post, the increased 64-bit instruction size actually slowed performance, though modern ...

For that you need to find another point on the polygon outline (with reasonable accuracy, that is set to 0.01 m in below script) connect 2 points by line split polygon using this line INPUT: OUTPUT: To make script below work, you’ll need to put three layers listed from the top down in your mxd table of content: empty polygon layer to store ...
