The Intersect tool does not require two inputs. The help for How Intersect (Analysis) works says "Intersect can run with a single input. In this case, instead of discovering intersections between the features from the different feature classes or layers, it will discover the intersections between features within the single input. This can be useful to ...

"Could creating a geometric network solve the problem? (ArcCatalog > Geodatabase > Feature dataset > Geometric network). Junctions will be created automatically at the intersections of the rivers." https://geonet.esri.com/thread/21850 Spatial ecology plugin does it simply as well. The tool is isectfeatures (Intersect Features) ...

I don't believe you can do this, but one workaround is to add a dummy polygon layer to your project which has no features in it, but has the same symbology as your extent indicator. Add that layer to your legend.

For best logo results, make sure you start with a PNG that has high pixel values, like 3500x3500 (if it's a square). Next, make sure you shrink that down to at most a couple inches. For export settings, set DPI to 600, and Image Compression to "LZW". Then export to PDF.

If this is a linear referenced network then create an event table with two measures (i.e., the midpoint measure you calculate in step 1 and a second measure at X distance offset from the midpoint measure). Then if the values you want to sum are also events then you can merge the event tables using Overlay Route Events. This will only merge events on the ...

If I am understanding you right you started out with an NLCD raster and a polygon feature class of your grids. You then converted the raster to polygon within each of your grids cells to yield polygons with the corresponding NLCD land cover class. Spatial Analyst Approach: I would redesign your workflow as follows: Before converting to polygons I recommend ...

My general opinion is that this is a lousy tool for creating a DSM however, @Andre Silva hit the nail on the head in using the maximum argument and you should mark his answer as correct because it directly addresses your question. Ideally, for a DSM you should use the first or last returns with an interpolation algorithm, and not merely a binning approach. ...

An average point spacing of 0.3 is approximately equal to a point density of 11 returns per unit of area. In theory, it should be sufficient to generate a DSM with pixel of area 1. As explained here, my understanding of a LiDAR DSM is: DSM as a raster. This represents the first echo the laser received for each laser pulse sent out, and represents the ...

An alternative to CSV or dBase is to write to a personal geodatabase table, which is essentially an Access table. You if need your data in Excel (xlsx) then you could import it with the tools in Excel. I would recommend writing to a personal geodatabase as it will accept unicode characters, so all your problems discussed above simply go away. You also write ...

You can download Python package XlsxWriter, write a script and import to your toolbox for use in your model: https://pypi.python.org/pypi/XlsxWriter

Try this on a new numeric field def isWrong(shp): try: b=shp.firstPoint.X; return 0 except: return 1 ------------------------- isWrong( !Shape!) and select records with 1. Note you can delete features using tool outside editing session. If the outcome are 0s only, I afraid there something else, not a bad shape.

Use summary statistics with your counties layer Use Get Field value to grab the sum from the summary table And Calculate Field to update somewhereland

ArcMap has Extend Lines in the Editing Toolbox. A Standard or Advanced license is required. The Parcel Polygons might need to be converted to Lines and added to the same feature class that you are extending.

A feature only ever has one row in an attribute table. If you have a requirement that suggests you need two or more then I recommend using a second table and adding a relate to it. The help page About joining and relating tables is well worth reviewing.

I believe it is GDB_ITEMS. Look for records in this table with a type of 4ED4A58E-621F-4043-95ED-850FBA45FCBC

Assuming your species binary raster is represented by 0 (absent) and 1 (present) MAJORITY — Determines the value that occurs most often of all cells in the value raster that belong to the same zone as the output cell. MAXIMUM — Determines the largest value of all cells in the value raster that belong to the same zone as the output cell. Since it ...

If you have access to an Advanced ArcGIS license, you are able to run the Simplify Line tool, which remove unnecessary vertices while preserving the feature's basic shape. If not, you can access similar functionality via the Generalize or Smooth tools on the Advanced Editing toolbar in ArcMap. You could therefore: simplify the features to a known ...

The supported mechanism would be to edit the version pinning the top of your state tree, but that will cause attribute conflicts with every row in every version unless you also apply that edit to every version. Then you could reconcile this 51st version and post the change. For this particular case, it would be faster (and risky, and unsupported) to make ...

You can create two new fields in your hydrants feature class attribute table, populating them with the x and y coordinates of your hydrant points. Then use both of these as your analysis fields within the Grouping Analysis tool.

Convert the font or image into an EMF vector graphic in graphic software such as Adobe Illustrator then use it as the picture marker symbol and it will be rendered as vector. You can also add any EMF vector (i.e. logo) to map layour as image and it will also render as vector. You can introduce 100% transparency to remove backround but only solid and 100% ...

Look at the Spatial Join tool. In the Field Map, you can right-click a Field name, select Merge Rule, select JOIN. Join acts as Concatenate. You can also define the delimiter, such as a comma, in the Properties dialog of the Field.

Looking at your model it appears you have accepted default naming. I'm guessing that one viewshed that is created is always the viewshed for the very last row in your input table? I guessing that the model runs for a long time but creates a single output? The reason this is happening is that you are not changing the name of the output of the Viewshed tool, ...

Create centre points using one of possible technique. I suggest centre of largest inscribed circle. You can find solution in here: Checking if polygon fits inside another polygon using ArcGIS or QGIS? Create 8 same length long lines starting from same point outside any of your polygons. Select them, copy,paste and drag to the centre points. They'll snap. ...

As a one time operation, I would do the Spatial Join to create a new FC and then transfer the data over using a standard join and field calculation. Then destroy the temporary spatial join feature class. In my experience this will be faster than any method based on looping through multiple Select By Location operations for each point or polygon or other ...

Sadly the Nibble tool requires an integer input. However, you could create an integer grid by multiplying you data by a factor equivalent to your acceptable scale. So, if you can accept, say five decimal places, create an integer grid from your raw input raster by multiplying by 100000. Perform the nibble and then divide by the same factor. Obviously ...

This would be a two or three step process. First dissolve all lines into a single feature (do not indicate a dissolve field). Next, split lines at points using your station feature class as the point input. You may then need to perform a multipart to singlepart as a final step.

This is comment, but comments box is too small. Are you able to make end points and delete spatial duplicates? The answer should be yes, because ArcGis has this tools. Are you able to assign nodes IDs to lines? Answer should be yes, there are multiple posts, e.g. Assign point IDs to respective start and end attributes of a polyline Thus your question ...

To answer my own questions (as far as I can tell) No: The random point generator does have the same feature as the buffer tool. It cannot accept text Yes: the units random point minimum distance uses are the map units. I was wrong about this (idiot -- can I downvote myself? I can't). One needs to be aware of the map units and convert appropriately

I'm sure you've moved on since the question was asked but I wanted to pass along a doc on what might be happening here for users who land here. Error: Failed to connect to database. Bad login user.
