Create a definition query on your DDP layer to only show the pages you want. Refresh your Data Driven Pages. Run your DDP again. This will only print the pages that you specify.

This can easily be done by using a spatial join. Here are some step by step instructions: http://support.esri.com/technical-article/000008599

The easiest way to achieve this is to use the Spatial Join geoprocessing tool. After running the tool, a new field Join_Count will be calculated in the states feature class with the number of features that fell within each state. Target features: states; join features: points.

A standard ESRI tech support response would be to rename the templates et al folder (C:\Users\your user name here\AppData\Roaming\ESRI to see if that fixes it. If it does but you have customizations you don't want to redo, you could get rid of the new folder and rename your old back to the original, and then try renaming individual templates starting with ...

you could create thiessen polygons around each raster value (using euclidian allocation tool). Then you can extract the value for each point using extract value to point. Note that distance analysis at global scale has two problems: 1) there is a rupture in the map (usually between -180 and + 180) and the scale is not constant.

If your extent is a round number of kilometres in each direction then I would use the Create Fishnet tool twice: Once to create a single cell fishnet (LINE not POLY) that matches your DEM extent The second one to place label points in rows and columns at the 1 km interval you desire, ensuring that the outside ones fall on the extent Then you can use the ...

As commented by @MichaelMilesStimson: I've always found in a right pain to edit inside a geometric network. In order to re-model connectivity is necessary to break, move and then reconnect. There are also times when you'd like to move a line over another without breaking it. Usually I would edit without the benefit of a topology or network and ...

I ran the zonal statistics as table again with all the setting identical to the previous try on arcGIS 10.3x and got the correct output with all the desired columns (Image as below).

This is a bug, let's hope that it will solved soon because you loose the median column. The Feature ID header is missing then all column header are shifhted one step left.

Try editing the file once installed on your system. You are getting the error noted above because you have changed the file as recorded in the digital signature which violates the signature. Once installed the file should be located at "C:\Users\username\AppData\Roaming\ArcGISSolutions\ConfigFiles\loaded.water.config". The AppData folder may be hidden and ...

I am not sure what are you going to extract from the following formula because it is strange. The formula says multiply the elevation of the DEM by 1000 OR if the DEM values are more than or equal to 2m it will output 1 where the condition is met, and 0 if the condition is not met (thanks to Luke for his clarification), which does not make sense. But the ...

You need to add another data frame to your layout. In that new data frame you copy all the layers you want to display in your inset. The easiest way to do this is to just drag and drop from your main data frame into the new one. This will copy them to the new data frame. Insert Data Frame Copy layers to new Data Frame Once you have your new data ...

I have figured out what the issue was. I had to add the ArcGIS Online Reader for the existing Feature Layer before adding the ArcGIS Online writer. Then I had to copy the "Layer Definition" from the previously added ArcGIS Online reader for that Feature Layer. Then it worked as expected.

There is a tool where you can export your active dataframe as a garmin custom map. Its a toolbox with a python script that exports what you are seeing on your active data frame to a .kmz that is also readable by your GPS (the garmin webpage tells that your GPS should be able to). The advantage of this toolbox (beside nothing necessary to install, free ...

ArcGIS, assuming you are browsing the data, doing edits, analysis and what not, needs virtually "continues" access to the database. Each zoom or pan request will trigger SQL statements send to the database to get the latest results. You are live on the database with ArcGIS Server (ArcSDE). If your administrator is not familiar with (ESRI) GIS and is ...

Export it as tiff with world file and then use OkMap's MapTiling/Garmin Custom Maps utility to create a tiled kmz for uploading to your GPS. I believe OkMap is free, at least for this functionality, and they do ask for donations if you like it. The utility always asks if you want to overwrite the projection and do so, and then find their version of the ...

When you make the kmz the image tiles have to be in jpeg format. The easiest way to do it is to put your kmz on an SD card. Make a Garmin/CustomMaps directory and put the kmz in there. I tested this on a kmz I just made and used it on a 64S and it worked fine. Visible in BaseCamps also.

According to Add Field tool help: Fields set as required are permanent and you will not be able to delete them with future processing. To allow for deletion at a later time set the field to non-required (the default). I think you can try to make a copy of your feature class to convert required field to non required and then create a new integer ...

I would suggest you to have a look at Image Analysis toolbar, which is very powerful and easy to use. In fact there is an in-built NDVI function as an answer to your query. Additonally I strongly suggest Band Aritmethic function in this tool for your possible further enquiries. Please see http://desktop.arcgis.com/en/arcmap/10.3/manage-data/raster-and-images/...

No, the values do not correspond to a probability but rather a confidence region. The 14 values are, a rather arbitrary, set of nominal representations of each of the predefined confidence regions. Analogously, think of a linear regression line with a set of confidence envelopes, with each incremental envelope indicating less certainty in the estimate. In ...

You need to use each single band as an image to do raster calculator in ArcGIS. Raster calculator cannot give you access to the multiple bands composited into a one image. However, you can access each band of the composite image from ArcCatalog. Navigate to the 5-band composite image from raster catalog, Drag and drop each band into ArcMap, Now you ...

Since you're only interested in areas where WPC is greater than 3, you can start by creating a subset of your wind potential shapefile which only contains polygons where this is true. Go to Insert > Select By Attributes, ensure your wind potential shapefile is selected, then create a query to select where "WPC > 3." Click OK, and those polygons should be ...

You could easily achieve this with modelbuilder: use a featureclass iterator to iterate over your shapefiles, this feeds into an add field, then calculate tool using inline substitution from a parse path tool to store the file name. Once you have run that you can run a merge tool bring them altogether into a single dataset. Basically read the help file and ...

You are using the ArcGIS 10.x for Desktop architecture while that documentation is for ArcGIS Pro. Consequently, for the ArcMap application, you will need to manually Save Edits.

SelectLayerByLocation requires a Layer to select features, you can't select features directly on a feature class, which is what your script is trying to do. The reason it worked in ArcMap is because in ArcMap you were referencing the map layers rather than feature classes. Add a MakeFeatureLayer and set your SelectLayerByLocation to select that. for grid ...

I assume you have elevation data with you and based on that u wish to assign slope values to the polygon. Step1: Divide the center line into segments the way you wish to have the slope calculation.

In layout mode, hold ctrl+shift+b then use left-click to zoom in or out (left-click-hold+drag cursor) or right-click to pan (right-click-hold+drag cursor). It's a long reach for the fingers, but is really nice for layout adjustments.

Was going to write long answer on how to solve this issue but I think this, and this will do a better job explaining if its not obvious(and no Geonet Login).

The problem is maybe with the type of your geometry as you see its type is Polygon Z in ArcGIS but you are trying to convert it as polygon to use it in PostGIS. I did some search and found this workaround: run Feature Class to Feature Class tool then (before executing it) in 'Environments' at the bottom > expand Z values > set 'Output has Z Values' to ...

You can try this code instead: arcpy.Calculatefield_management(fc,"time",!DATE![9:len(!DATE!)]) Len gets the length of the string the square brackets are saying, "Return the 9th character of the string (in date) to the last character of the string"


2

You are close, but the (r)split will create a list. Therefore you need to get the element from the list (-1 for the last one) arcpy.Calculatefield_management(fc,"time",!DATE!.rsplit()[-1])


3

arcpy.CalculateField_management(fc, "time", "!DATE!.split(' ')[1]", "PYTHON") This uses Python to split the string at the space (which returns a list containing the date as a string and the time as a string), and populates the field with the second item in the list, which is the time.

No need to export to single bands, there are a couple of ways of adding individual bands directly from the original multiband dataset: double click on the raster dataset in the file dialog. click on the + symbol next to the raster name in the Catalog window in ArcMap (or ArcCatalog). If you can't see any + symbols in the Catalog window tree, click the ...

Paraphrasing a comment by @SaultDon: If the buffers use ARCS/CURVES instead of regular linestrings, then be aware that the openfilegdb and esri filegdb api driver both don't support curves in geometries unfortunately. See QGIS 2.8.1 OpenFileGDB compatibility with ESRI FileGDB?

Another solution (not guaranteed) might be to open the installation file. I once reopened an installation file in order to identify the exact file the toolbar was stored in (to remove it with the Add-in manager). The developers had placed the tool removal option in the the installation package.

You can simply add a new field named area with type double, then right-click the field name, go to calculate geometry. In the property field, select area and choose meter square as units. Then go to Select by Attribute and select the areas that is more than the threshold area and save the selected polygons into a new shapefile.

Yes it is possible to create a custom basemap for a Garmin unit. It isn't straightforward or well documented. It definitely isn't supported by Garmin. There are a few ways of doing it, but the steps I used involve these software: GPSMapEdit - import shapefiles into a Polish Map format file http://geopainting.com/ Cgpsmapper - convert the Polish Map Format ...

The parentheses in your label "(" and ")" are text values that are added to your [AREA] value, so you can add any other text you want with it. "(" & [AREA] & " sqft)" will produce something like (1000 sqft) as your label.

If I understand what you are trying to do, you don't need to dissolve, you just need to summarize by landscape zone after intersecting the two datasets. If you do this in a geodatabase the area of each polygon is calculated when the intersection is completed.

Be sure to check "Code Block": def calc_X(A,B,C,D): if A == 0 and B == 0: return calculation_1(A,B,C,D) elif A == 0 and B != 0: return calculation_2(A,B,C,D) elif B == 0 and A != 0: return calculation_3(A,B,C,D) else: return calculation_4(A,B,C,D) Then: X = calc_X(!A!, !B!, !C!, !D!)

In your Table of Contents (the list of layers usually found on the left side of your ArcMap window), right-click on your US border shapefile and click "Zoom to Layer". That will zoom to the extents of the layer and center your view on the layer. FYI, you can also zoom to one (or several) features in the layer, instead of the entire layer. To do that, open ...

If you center your map in data view, layout view should show the same extent.

Since you are using the field calculator on that given field you can just use this with codeblock enabled.

You donĀ“t need to bring your calculated field in the return part of the function: Try: if [Area_Ha] <=70 then [Area_Ha]^1.22 * 2.85 else ([Area_Ha]+9.97)*7.1 end if
