It's not particularly obvious but it can be done per data frame:
Open your data frame properties;
Click the coordinate system tab;
Click the dropdown next to the coordinate system (globe) button;
Here are a couple of items to explore to determine why ArcGIS is not registering your PostGIS tables as feature classes:
ArcGIS will refuse to acknowledge tables that have mixed geometry types. To clarify, "POLYGON" and "MULTIPOLYGON" types can be mixed within the same column, but POLYGON and POINT cannot. In your case, coming from a shapefile, this is not ...
Based on @Felix's answer, here's an approach that uses built-in methods on geometry objects. Supported on 10.3+.
from math import atan2, pi
e = 1e-10
def tangentLine(line, dist):
'''creates a tangent line of length dist at line midpoint
line - arcpy.Polyline() object
dist - distance in meters
midpoint = line....

In the field calculator, your parser should be set to Python. With "Show Codeblock" checked, your function definition should go in the "Pre-Logic Script Code" and the expression box at the bottom should be populated with:
Your code block should end with the return function as well.
The "Calculate Ranges" example on the ArcGIS help page ...
If you only have access to ArcGIS Desktop or Engine, you need to install the Background Geoprocessing for 64bit, check Python scripting with 64-bit processing at the ArcGIS Blog. If you have ArcGIS Server, the 64bit Python will be automatically installed.
A Help page on that:
What is 64-bit Background Geoprocessing?
You are almost there. What you are trying to do is:
if field_value == 'S1100':
if field_value == 'S1200':
You have to evaluate the value of MTFCC field and then make decision based on that.
Imho a more elegant solution is to use a Python ...
Create midpoints, using one of multiple possible techniques.
Buffer them by small number, e.g. 0.5 m
Clip originals by buffer, output - SHAPEFILE
Use this field calculator expression on field Shape:
A DataFrame object has an extent property, the extent property/object can be used in the basic spatial relationship methods of contains, within, equals, overlaps, touches and disjoint as well as distanceTo, see here for more details on those methods.
With that in mind you can loop over the layers you retrieve from calling arcpy.mapping.ListLayers(mxd,"&...
QGIS is made to use Write Ahead Logging (WAL) by commit https://github.com/qgis/QGIS/commit/f939e9cff598b95e95b0de099d0c9a92eed0ea9c
The new behavior should be to open gpkg database file in WAL journal mode if file is on local disk but turn it back to the default journal mode when the connection is closed.
I made a test with QGIS 2.18.2 and that seems to ...
As a quick and dirty method, you could compare extents, as already answered. However (also mentioned), that doesn't necessarily indicate whether a feature is visible in the current view (e.g. if you zoom in far enough within a feature class' extent, at some point you will not see any features).
There's a definite performance hit if you need to find visible ...
Click on Customize > Customize Mode
When the window opens, just drag the Customize menu option from your toolbar.
Now the Customize option will be gone from your menubar.
To get it back you will need to open Customize Mode again, this time from a right-click on a toolbar > Customize (since you've removed the Customize menu). On the toolbars tab scroll ...
Because the properties of a 'Describe' object are not a fixed list as they are for the other object types in your autocomplete examples. The list of properties depends on the type of object passed to arcpy.Describe(). As the Esri documentation puts it:
The Describe function returns a Describe object, with multiple
properties, such as data type, fields,...
Unfortunately, the Portal for ArcGIS is not available directly to ArcGIS Server 10.1 users. You are supposed to obtain the software/license via your local Esri distributor. In 10.2, however, the Portal for ArcGIS media is included with ArcGIS Server. This means you are able to install the software on your own (i.e., download via Customer Care portal). The ...
You can do this for many fields with some Python. This is a stand alone example, but it'd be easy to write this into a script/Python toolbox. Or you could embed this into another loop and do this on a list of feature classes/tables.
Keep in mind this approach will make the changes to all short/long integer fields:
features = 'SomeGDB.gdb/...
Tkinter is not compatible with any version of Arcmap desktop. As a script you are running pure python, and not using the ArcMap desktop application at all, which is why you are seeing different behavior. Esri has determined that tkinter and Arcmap desktop conflict in their messaging designs and they will not resolve the conflict, so tkinter is not supported ...
You can set the placement properties which should take care of this. Go into your layer properties and click on the Labels tab across the top. Click on Placement Properties... and then check the Only place label inside polygon box as shown below.
There is a bug discovered in ArcGIS 10.3, so it probably applies to newer versions since it hasn't been solved:
Bug BUG-000084520 - Field values in a shapefile attribute table are corrupted when viewed in ArcGIS 10.3.
It shouldn't occur in older versions, but I can't test this to confirm, and it's probably not a convenient option for you neither.
Esri provides a guide on how to choose CELLSIZE, Assessing lidar coverage and sample density
For sampling, choose CELLSIZE. You might think the average point spacing is a good cell size for the output raster, but this typically results in too many empty, or NoData, cells because lidar points are not evenly spaced. Also, the output raster could end up ...
Data is not stored in the MXD, so if you move only the MXD the data will not be moved as well.
If the data is moving with the MXD, then under File > Map Document Properties check off "Store relative pathnames to data source".
If the data is not moving with the MXD then make sure the path where the data is stored is accessible on the new machine.
In your answer screenshot you opened the python interpreter in your command prompt by typing python. This is similar to the ArcGIS (or QGIS) python consoles. This is where you can write python code, but it is not how you install new python packages.
To install a new package, all you need to do is run pip install <package name> from within your command ...
You are listing field objects with ListFields, not the field names which should be input to DeleteField. So change:
[field for field in fields if field != "FID" or field != "Shape"]
[field.name for field in fields if field.name not in ("FID","Shape")]
But it is probably better to use the required property since object id and shape fields can have ...
The download for the 64 bit geoprocessing installation is not freely available. I found it in my.esri.com under My Organizations -> Downloads -> ArcGIS for Desktop 10.4 -> ArcGIS for Desktop Background Geoprocessing (64-bit).
I tried this code and it worked.
arcpy.env.workspace = r'C:\GIS\MyRasterFolder' #My directory of rasters
rastList = arcpy.ListRasters()
myNewRast = arcpy.CompositeBands_management(rastList, r'C:\GIS\rasterCombined.tif')
(If this doesn't work for you, if you could post the code you're trying to run and the error message you're receiving, that ...
An m-aware polyline has the ability to store m-values (in addition to x and y values). M-values are 'measurement' values, for example the distance along a given line. They are often used in linear referencing datasets.

Assuming r"E:\depthtester2.npy" is a saved array, use numpy.load to avoid the ValueError, and as noted in the comments, you need to pass a point object to NumPyArrayToRaster or you'll get a TypeError.
myarray = numpy.load(r"E:\depthtester2.npy")
myRaster = arcpy.NumPyArrayToRaster(myarray,arcpy.Point(0.0,0.0),1.0, 1.0, -99999.0 )
Script below designed to run from mxd. It assumes that you have empty a table (“nearLines”) to populate in mxd:
Where pointID and lineID are fields to store OIDs of input layers (type long), Distance field type double.
# parameters to re-type
mxd = arcpy.mapping.MapDocument("CURRENT")
# get lines
lines = arcpy.mapping....
Assuming your polygons are stored in a geodatabase and are in a projected coordinate system (PCS), you could set a label expression based on the SHAPE_Area field. That field contains the area of your polygon in whatever unit your PCS uses, for example if you are using UTM with meters as the linear unit, SHAPE_Area will give area in square meters. It's also ...
Firstly, "SHAPEFILE@WKT" should be "SHAPE@WKT".
Secondly, your WKT will be in exactly the same coordinate system as your shapefile. If you're getting strange results, your data is probably not in NAD 1983 UTM Zone 13N, but some other spatial reference and is being projected on the fly when you view it in ArcGIS.
To specify the output spatial reference for ...
