Shapefiles have a 100 byte header. As you indicated, the 2D point datatype uses 28 bytes. The maximum file size for a .shp or .shx is 2^31-2, because Esri chose to keep the 2^31-1 filesystem limitations in existence when the format was published (see this question/answer), and the 16-bit word size assures that the file will always be even*.
The general ...
To remove gaps and overlaps you should use the Topology tool. The Topology tool helps validate your data based on different rules you choose appropriate.
One of the many rules available in that tool is: (features) "Must not Overlap".
The tool has an "Error Fix" button that let you zoom to the error (in your case, an overlap) and let you choose what to do - ...
Using the Union tool is the answer. But, you will need to do a bit more work after you run the tool. All the overlapping and non overlapping polygon WILL show up in the attribute table. You will need to detect which are the overlaps an which are not by simply looking at the FID (some will have a -1 and some will carry over the FID from the overlapping ...
The previous answers are not complete/correct. There are two options for creating spatial functionality in a PDF. The first is the open standard Geospatial PDF. Users do not require the any proprietary plug-in to read geospatial PDFs created following the PDF 1.7 specification, which was published as ISO 32000-1 standard. Geospatial PDF's can be create ...
As you say in an answer that you have included within your question this appears to be Bug NIM084228:
Summarizing attribute tables return incorrect results with null values.
Esri have therefore acknowledged that this bug exists in ArcMap. ArcMap uses an architecture that is 20-25 years old, and which was superseded by ArcGIS Pro a number of years ago.
If I understand correctly, you are trying to remove overlap between polygons. I would suggest looking at the ERASE and CLIP tools. If you are talking about slivers (gaps) between polygons, you can use the align to edge tool on the editor toolbar, as well as the snap tool. If you can provide screenshots of your workflow and examples of your issue I may be ...
You need to connect the output "anomaly" to a make feature layer tool that becomes the input to the select layer by attribute tool. You need to do this because that tool takes as input a feature layer the output of the iterator is a feature class which is a very different type of object.
For clarity, let's call your two polygon layers Green and Blue. If I understand correctly, you want to:
Select those Blue polygons that intersect any Green polygons.
Export the selected Blue polygons to a third layer
To select the Blue polygons, I would use the Selection > Select By Location tool, with Blue as the Target layer, Green as the Source layer, ...
I also face that problem. I did not do anything mentioned above. I just uninstal the ArcHydro tool box. Then reinstall the ArcHydro tool for ArcMap 10.7 specifically. Then every thing is running perfectly. Try this
After a little research, I finally came up with the answer I was looking for.
when using Global Moran's I index (I) with incrementally increasing distance searches (thus, changing the weight matrix at every iteration), only the the z-values are independent from both weight matrices and variable intensity variations, thus, they are comparable across multiple ...
I have never gone the way you describe, probably it is just lack of arcgis.
What I do when I need an inundation boundary map is to produce the GIS file(s) directly from Ras Mapper, available as part of HEC-RAS.
In the result tree I add a new results map layer, then I choose an "inundation boundary layer" type and from there, that layer could be exported ...
This does not sound like a use case for the ArcGIS Spatial Analyst or a TIN data format.
If you know the area of a particular polygon, and that is easy to calculate for a shapefile, or is automatically calculated for a geodatabase feature class, then all you need do to get the volume that you are after is to multiply that area by the height you want to ...
Everything flowing into the iterator needs to run once. But as EVERYTHING runs as many times as an iterator loops then EVERYTHING is running...
Not what you want. The iterator and everything downstream of it needs to be in its only model and that sub-model connects to the output of the split by attribute.
You could look at a help file or search this site ...
This can be done in an edit session. (right click on your layer, then "start editing")
Select the entities that you want to move
go to the Editor menu in the Editor toolbar
enter the shift values for X and Y translation (also Z if you have 3D analyst)
Yes this is possible, but it is most easily done with the Network Analyst Extension. This extension is super in depth, and it will allow you to create routes for more than one driver, adding more than one stop, giving them a predetermined maximum time they can drive, timeframes to be at each location, adding start and end times, etc.
I think @PolyGeo is correct if you have ArcPro then Contingent Values is the way to go. But if you don't then domains and sub-types would work if when you create your feature on the map you use the template. If you then went back into the attribute table then yes you see the list of all values rather than a subset.
So to explain I created a text Domain ...
I believe you may need to reset the gamma using the Image Analysis window. If you read this thread (https://community.esri.com/thread/3285) and scroll down to the reply from allisamcmasters and follow their instructions this might make your image appear when you click 'zoom to layer'. It certainly worked for me with a similar problem.
There may be slight variations of a single approach that can be used. Let me elaborate that single approach step-wise.
1. Define or calculate intersection of roads
To split the road intersections into quadrants, intersections must be 4-way intersections only. Better if you already have only 4-way intersections point shapefile. Otherwise, you may need to ...
Or maybe this Python Function will be useful to some.
'''Converts Radians (East = 0 then counter-clockwise)
to Geographic Degrees (North = 0 then clockwise).'''
theta = math.degrees(theta)
theta = theta - 90.0
if theta < 0:
theta = theta + 360.0
theta = -1*(theta *...
I had a workaround to do this with a few conditions. it works and keeps the angle as you want between 0 and 180, transfering Geographic angles (Azimuth in this line of code) to your Arithmetric angle:
if(450-Azimuth<180, 450-Azimuth, if(450-Azimuth>360, 450-Azimuth-360, 450-Azimuth-180))
Make a seed2d file in microstaion where you define your projection and unit. In Arcgis desktop while using Export to CAD, Use the seed file in optional box. That will solve your problem. Same work for Dwg too.
Symmetrical Difference (Analysis)
Features or portions of features in the input and update features that do not overlap will be written to the output feature class.
Usage - The input and update feature class or feature layer must be of the same geometry type. Attribute values from the input feature classes will be copied to the output feature class.
If you have a Spatial Analyst Licence, you can use the Extract Values to Points tool which:
Extracts the cell values of a raster based on a set of point features
and records the values in the attribute table of an output feature
If your 5000 xy coordinates are not a Feature Layer, you can follow these steps to convert a table (e.g. a csv or ...
You do not specify which ArcGIS Desktop application you are using so I will assume ArcGIS Pro. In any event the workflow is probably the same in ArcMap for this part of the software.
You could try to do the following for each species:
Use the Select (Analysis) tool to create two feature classes for one species from each survey. I'll call them SurvA_sp1 ...
You have a tag for ArcGIS Desktop so I assume that you are using ArcGIS Pro 2.x or the ArcGIS Desktop 10.x applications (ArcMap, ArcCatalog, etc).
In any event the word "tranchieren" does not appear in the German documentation for ArcGIS Desktop: https://desktop.arcgis.com/search/?q=tranchieren&p=0&language=de&product=any&version=10.7&n=...
This is most likely due to numerical rounding and precision. As currently implemented in TauDEM, the aread8 results are held in a "float" variable in C++ which has about 7 decimal digits of precision (line 152 in https://github.com/dtarb/TauDEM/blob/Develop/src/aread8.cpp). Specifically, if the number 1 is added to 26648268 numerical effects will result in ...
If you follow exact steps from ESRI, it works and will produce something like that:
I don't like that they are disconnected. Perhaps create sub-catchments from stream network and assume that divides between them ARE ridges:
Note smaller flow accumulation threshold you'll use to derive streams will result in more detailed ridges network.
Consider erasing ...
What you are describing sounds like the use case for contingent values:
Contingent values, sometimes referred to as contingent attribute
values, are a data design feature that allow you to make values in one
field dependent on values in another field. Attribute domains allow
you to restrict the valid entries on a field to a set list or range of
I found a solution/work-around:
I've simply split my polygon (that contains 6+ million records) into smaller parts (sub-watersheds in my case) and dissolved the smaller feature classes (which varied between 300k records to 1.2 million records)
Next, I took those sub-watersheds feature classes and merged them all together. Lastly, I dissolved the merged ...
To export GPX files as CSV from Garmin Basecamp, select the waypoints you want to export and then:
Save as Type csv and select where to save the file
You can find more information on Garmin's info page here.
Alternatively, ArcMap can directly import gpx files using the GPX to Feature tool. Documentation on the tool is ...
What have you set the output of the copy features tool to be? You need to make it a unique value on each iteration, otherwise you simply end up overwriting the output.
You typically get the value out of the iterator. So I would expect to see the output featureclass to be something like:
%Name% is coming from the iterator ...
This happened to me with 10.6.1.
Sometimes the window moves so that you can see a very small portion of it on the edge of your active monitor. Look closely at the edge of your screen to see if there is just the border of the window there. If so you may be able to grab it (even enough just to resize it a bit) and then drag the window into your main screen.
One other solution is to create/insert two legend element, one for each of your column (each containing only the layer you want depending on the column and each with the correct option to display all or only visible classes)
The downside are you spend twice the time fine tuning the legend and the alignement between the two are not always easy to get right......
I have the same issue with DDP and I get around it by having the the first two items in the legend, "Preserved Lands" and "Conservation Easements" for you, be what will always appear on every page. Then have the third item be what will only sometime show. Then on the second item check the "Place items in new column" and make sure it is unchecked from other ...
I created a blank seed file of the drawing file and assigned unit meters and projection system sweref99 12 00 to it. While running a model in the setting of export cad, given seed file as an optional, after that all converted .dwg files are having correct unit and projection system.
For someone willing to consider any alternative (not just ArcPy), the Union geoprocessing tool in QGIS provides precisely the desired functionality. Within QGIS, go to Vector --> Geoprocessing Tools --> Union and select the two layers.
My initial approach was to use the Data Management Tools --> Raster
--> Raster Processing --> Clip function with a shapefile of the lower 48 as the Output Extent.
From that description it sounds like you have a single shapefile with 48 polygons representing the lower 48 states. The tool has likely used all polygons so it's clipping out a ...
Alright: I've figured this out. It has to do with the settings.
I was exporting my map with high resolution settings
Resolution: 300 dpi
JPEG Quality: 100
This led to the output PDF being exported without the WMS layer (imagery). However, with the settings set to:
Resolution: 300 dpi
JPEG Quality: 85
Everything exports properly and ...
I could be way off here as I cannot offer the complete answer but wouldn't the tool be failing at the select data point because you have just imported the accounts from an excel spreadsheet, there has been no feature geometry created yet to assign XY coordinates to?
Your coordinates look like they could be in WGS 1984 - Pseudo Mercator (Web Mercator, EPSG 3857. Web maps often use Web Mercator, so it is a likely candidate), or World Mercator (EPSG 3395). In both cases, your example point would fall near the UAE - Oman border. Check to see if one of these fit your data correctly.
Some tools like projfinder and epsg.io ...
As pointed by mkennedy, the Description of CRS - SI_D48 / SI_TM, from the Information and Service System for European Coordinate Reference Systems, expresses that SI is the 2-digit country code for Slovenia and D48 is the datum.
The description of the projected coordinate system defines also the parameters of the Transverse Mercator Projection conversion ...
Create two lists, one with even and one with odd numbers. Then sort each and combine. I copy-pasted your data into a csv file.
import arcpy, os
testfile = r"C:\GIS\data\testdata\sortme.csv"
outdb = r"C:\GIS\data\testdata\testdatabas.gdb"
outtable = 'sorted2'
How do you do this using ArcGIS Desktop?
You use it as an external data source, you can query at any point location to get the underlying data (the clay layer is queryable), but you can't directly access the full data though the WMS.
I put full data here, because as can be seen in the GetCapabilites response for the clay service:
You can't*. A WMS serves rendered map images not data.
You can use data.isric.org to download the actual data instead.
* You can save a georeferenced raster of the WMS map image, but you're still only getting the rendered map, not the actual data.
If you aren't comfortable guesstimating based on the building addresses on the street, try looking in the local county or municipality geoportal for some sort of grid of address ranges. For example, the image below is a screenshot of the address grid of points from Pima County.
Correct. Python is for "Pros" and people who want to advanced themselves. Model Builder is limited, and good for beginners or people who just don't understand how to program. Yep dead end threads are true simply because Model builder is a dead end solution. ;)
Python is really powerful and where its at, and and can be used just about anywhere. Take the ...
