The new site features an updated design and new tools to strengthen learner engagement, support focused learning goals, and personalize the user experience. One thing that's not changing: our laser focus on providing easy access to…(Show moreShow less)
From what I can tell, it might not be possible to perform image classification on a basemap. Take a look at this thread for potential alternative ideas: raster - Image classification from "Imagery" basemap ArcGIS 10.2 - Geographic Information Systems Stack Exchange Would using Landsat data be a suitable alternative?
Charles, I do not think you can sort a text field numerically. You will have to make a new field that is an integer (or float) and sort it from there. However, there are some options listed here: How to Sort String Type Numbers by Absolute Value In Attribute Table
Hello, I have a column for elevation for a point data set. I would like to create a new column to show a difference between Row(n) and Row(n+1) values. well, I assume that the easiest way is calculating in EXCEL (=abs(A1-A2)) then make a join at ArcGIS. However, I would like to the process with "Field calculator" Does anyone know how to do…(Show moreShow less)
Learn GIS ... some python? Could make this into a script or copy and paste into the python window or your python IDE # ---- # (1) specify the table you want to use, with the OBJECTID field and # the field you want to get sequential differences for # (2) convert the table to a numpy array... there is some magic in that we # 'view' the…

There is probably a more elegant way to do this, but one approach would be to use the Dissolve (Data Management) geoprocessing tool. When running the tool, to make it dissolve based on spatial location, do not check off any of the checkboxes under the setting Dissolve Field(s) (optional). This will result in a feature class with one record - a…

When I add XY (lat,long) data to the map in the same PCS and GCS as the other layers, the points are added to the map but do not line up with the other layers. I am using GCS: GCS_North_American_1983, and PCS: NAD_1983_UTM_Zone_16N. When I change the XY data to WGS_1984, the points appear on the other layers. However, I am unable to run any…(Show moreShow less)
Here is what I would do: decide what projection you want to perform your analysis in. My guess is since you already have the polygons in some system, you'll probably use it. Add your xy data with the method that gets aligned correctly and then save that event layer as a feature class in the same projection of your polygons.
Back in December 2018 we released the following sample dashboard related to local law enforcement. We leveraged selectors that enabled the end user to easily filter down the dashboard to a specific time window, police division and/or crime type. With the latest April 2018 update to Operations Dashboard for ArcGIS, we’ve added the ability to…(Show moreShow less)
