I might expect the results for area calculated in the projected space to be different from those using geographic coordinates. It just depends what areas the tool claim to compute. Consider the "square" whose corners are at the UTM coordinates 18n 528007 4467447 18n 528008 4467447 18n 528008 4467448 18n 528007 4467448 It might be plausible to ...

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 ...

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.

So the reference work for understanding what has happened here is Understanding Coordinate Management in the Geodatabase (unfortunately, Esri broke their website this weekend, so I can't link to their site at this moment). Essentially, the fact that "projections match" is of no consequence, because a coordinate reference in ArcGIS encompasses more than just ...

Why not try to add the attribute table from .dbf file, open it in Excel, create your table design, and in the end, add it in ArcGIS as an object?

You can do the analysis described in your post without converting the raster to a polygon. Use the raster::extract function to extract the raster values to each polygon. You can then use lapply on the resulting list object with table to return cell counts of each class. For area of each raster class, you just use a standard conversion of cell area and ...

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 ...

You have 1000 images for which you have built a mosaic dataset and they are in some coordinate system, or even a mixture of coordinate systems? Your client wants all the source rasters supplied in an equal-arc coordinate system? In ArcGIS 10.4 there is a tool Export Mosaic Dataset Items which honours the environment setting output coordinate system. Run ...

Remove overlaps and zonal statistics will perform as expected. Extract from tool help: If the zone feature input has overlapping polygons, the zonal analysis will not be performed for each individual polygon. Since the feature input is converted to a raster, each location can only have one value. An alternative method is to process the zonal ...

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

Have a look at EUDCEDIT. It's a "hidden" program that is included in most windows versions that can be used to edit and create fonts. I have used it do do exactly what you are trying to achieve. Once you create your font, it will appear under the name "EUDC" in your list of fonts available through the "Character Marker Symbol" type in the "Symbol Property ...

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% ...

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 ...

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 ...

As @MichaelMiles-Stimson says a 10.4 toolbox would not open on a 10.3 machine. But it is not clear if you have tried Save As? Simply right click on your toolbox and Save As to save in a different version. Also I have 10.4 and have had troubles with saving backwards when the toolbox contains a script tool (did not seem to affect models). I opened a long ...

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.

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.

No 100% solution, but i did find a trick that seems to improve the crashing on launch. When I crash on launch over and over I start the task manager and look for two processes: ArcGISCacheMgr.exe and ArcGISConnection.exe, and i force-quit both processes. I believe they are supposed to quit themselves after quitting ArcMap, but I often find they do not, ...

You may download the image section you need from http://glcf.umd.edu/data/ http://landsat.usgs.gov/ https://lta.cr.usgs.gov/high_res_ortho The downloaded image-subsets should be rectified. Also you could use SASPlanet, a software to view and download georeferenced images of high resolution satellite maps.

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.

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.

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, ...

Feature Builder is part of the Production Mapping Extension. A useful tool I have used for measuring bearings is the COGO Report tool. It is included at the Basic license level, I believe, so you should have access to it. Find it on the COGO Toolbar. One of its functions is described as such: Reports the direction and distance between two points you ...

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. ...

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.

You cannot add a display indicator as an element to a legend in ArcMap. You could build an element using graphics and just place it underneath your legend. It's usually not terribly hard to copy the formatting of the patch and text.

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 ...

Your question sounds quite odd. .tfw and .mxd are totally different in their character, and there is no way to convert them. The first is a World File - text file containing parameters used to georeference raster; .mxd is a map document (equivalent to .qgs). But I deduce that you cannot open your GeoTIFF in ArcGIS. This might be a problem with .tfw World ...

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 ...

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 ...

A lot of online services display in WGS84 Web Mercator, which calculates distances terribly, so they calculate distance along the ellipsoid (geodetic distance) in the background, rather than the direct planar distance. (Whether they are using the correct ellipsoid formula or not is for another question.) ArcMap is more of a professional tool and makes no ...

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 ...

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.

You can use the Path Distance Allocation tool to get the nearest source to each cell on your raster. Let's call the result of using the tool the source_raster. The source here would be the unique ID of your health facility points. This will be your service area raster if you just want to know the nearest health facility. If you want to distinguish areas that ...

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.

I don't think there is an elegant way to do this but the following will work, it would be best as a Model Builder model or python script, but it will be much slower than just doing a spatial join: If you first use the 'Near' tool, that will add the unique ID of the nearest polygon to your point feature class. It will also tell you the distance between the ...
