I need to have a line graph in my layout and I want to show the series without the markers on the line. The dialog to adjust symbology for the series does not offer any way to influence the markers, other than changing the colour (for the entire graph). The issue for me is that the markers are out of my control and the chart in my layout is essentially dominated by those markers and not by the line graph, thereby obscuring the information.     ...

I have the issue that information from a colormap file are simply ignored in our 10.9 portal. Creating either a mosaick or an image collection, I can provide a colormap file during the setup. When I click in the checkbox a 'File upload' dialog opens and I select my clr file. However, the checkbox never gets 'checked' and when the imagery layer is created, the colormap is never used. Instead, the imagery layer comes with a grayscale stretch, and styling the layer inside the portal is, at least in 10.9, not really possible. Styling imagery layers in 10.9 is/was also beta functionality... There is also the range of pixel values shown in the Map Viewer that puzzles me. The stretch goes from 0 - 255, while the pixel values only are 10, 20, 30, 40, 50, 60, 70, 80, 90, 95, and 100. ArcGIS Pro does understand the colormap when adding a single TIF file, but the portal does not use the information. When I select 'Unique values' as symbology type in ArcGIS Pro then a raster attribute table needs to be created and thereafter all the non-existing pixel values do disappear from the legend. In addition I can label the different classes. Initially, I started with a colormap syntax like this one: 10 0 100 0 255 Tree cover Looking at https://pro.arcgis.com/en/pro-app/latest/help/analysis/raster-functions/colormap-function.htm I threw the last two values over board and ended up with 10 0 100 0 But the colormap I created should also not be necessary, since the colormap is already encoded in all the TIF files I am using for the imagery layer. -> Not regarded!   Is that a problem that was solved in portal version 11.*?   ...

I was trying to use Streamlit with my arcgis pro python clone, and while I can install version 1.10.0 of Streamlit, I cannot import it. import streamlit as st returns the following  File "C:\...\AppData\Local\ESRI\conda\envs\pro-py3-open30\lib\site-packages\pyarrow\__init__.py", line 69, in <module> from pyarrow.lib import (BuildInfo, RuntimeInfo, MonthDayNano, ImportError: cannot import name 'RuntimeInfo' from 'pyarrow.lib' (C:\...\AppData\Local\ESRI\conda\envs\pro-py3-open30\lib\site-packages\pyarrow\lib.cp39-win_amd64.pyd). Does anybody made better experiences using Streamlit? I also had to realize that Python 3.9.x is in 'security fix only' state and thereby the last version coming with a binary installer is 3.9.13... ArcGIS Pro 3.0.2 is using 3.9.11 and I was wondering with Python in stable release of 3.11.1, if ArcGIS Pro 3.1 will come with a more recent version of Python?   ... View more

I have one calculation where it works great getting a variable in:     arcpy.management.CalculateField(sector_angle, 'Buffer', "getBuffer(!Area!)", "PYTHON3", f"""def getBuffer(area): if area < {median_area}: return 1 if area > {median_area}: return 2""", "TEXT", "NO_ENFORCE_DOMAINS")     And I have another calculation on the same feature class where it does not work.     arcpy.management.CalculateField(sector_angle, 'Buffer_Radius', "setDistance(!Buffer!)", "PYTHON3", f"""def setDistance(buffer): if buffer == 1: return {pnt[2]} elif buffer == 2: return {pnt[3]}""", "FLOAT")     Some example on how the variables look: pnt[2] = 2043.8900146484375 pnt[3] = 4087.780029296875 The type of both variables is float, but the resulting 'Buffer_Radius' field contains only NaN.   I tried all sorts of stuff on how to get the variables into the code block, but while it was so easy in the first function, I don't have luck with the second one. How do I get my variables into the 'Buffer_radius' field?   ... View more

I need to analyze the area covered by some polygons. The analysis are based on mosaic and LAS datasets. Since the mosaic/LAS datasets contain several thousand raster and las files it seems to take ages to do the analysis. For example, to create my workflow I used a minimal subset of the LAS files to create a LAS dataset and the *StackProfile* analysis went within seconds. Now that I have more las files building the LAS dataset it takes 2 minutes to do the analysis. Hence, I was thinking to use the polygon to identify the files of the mosaic/LAS dataset intersecting with the polygon, extract their name (or better source path) and create smaller mosaic/LAS datasets on-the-fly. Can somebody help me out on how to query a mosaic/LAS dataset for the footprints and get the footprint name or source path returned? ... View more

When creating buffers, you have several options to dissolve the buffers, but what I am missing in Buffer, as well as in Multiple Ring Buffer, is the possibility to specify at least one attribute of the input features to be transferred onto the resulting buffers. Of course you can argue that I can do a spatial join, or intersect or something else to make the connection, but on one hand that means an extra geoprocessing tool run, and on the other hand, that only works as long as the object used to create the buffer is intersecting, or touching the buffer, or you search within a specific distance. Especially when creating multi ring buffers the intersecting and/or touching falls possibly short in case of all the ring buffers. The buffersize I use to create the multiple ring buffers depend on a feature value in the attribute table, which goes into a formula and the resulting distance for the buffers is calculated on the fly. Thereby, fishing for buffers in the vicinity is not much fun. Hence, I propose that the buffer tools functionality is extended by the possibility to transfer one, or multiple feature attributes from the initiating feature over to the resulting buffer(s).   ...

I need to project geometries in an spatial dataframe and try to do it with this code   import pandas as pd from arcgis import geometry from arcgis.features import GeoAccessor, GeoSeriesAccessor in_csv = r'C:\Path\to\points.csv' point_df = pd.read_csv(in_csv, sep=';') point_df = pd.DataFrame.spatial.from_xy(point_df, x_column='Longitude', y_column='Latitude', sr=4326) point_df['SHAPE'] = geometry.project(geometries=point_df['SHAPE'], in_sr=4326, out_sr=3006)   A check on the geometry column in the SeDF returns I am logged into our Enterprise portal when running the code, and I am getting: Exception: Invalid Token (Error Code: 498)   I am running ArcGIS Pro 3.0.2, our portal is in version 10.9 and arcgis is in version 2.0.1 PS: I am getting the same error when trying to find the transformation needed to do the projection   arcgis.geometry.find_transformation(in_sr=4326, our_sr=3006)     ...

I am just getting started with SeDF and I was wondering on how I can actually visualize objects with multiple geometries. Following the introduction, a buffer geometry is added to the dataframe. The map widget of my notebook is however, only showing the points. How can I visualize the buffer geometries? Is there a way to specify what geometry column should be used for the visualization?     # generates map widget visulizing the points, though info widgets places two objects there, when I click on a point point_df.spatial.plot() # AttributeError: 'Series' object has no attribute 'spatial' point_df.Buffer_2.spatial.plot() # Since plot generates a MapView, the object is not subscriptable point_df.spatial.plot()['Buffer_2'] # or has no attribute 'Buffer_2' point_df.spatial.plot().Buffer_2     ...
