Microsoft Excel is a popular format for storing and analyzing tabular data. While you cannot edit Excel data in ArcGIS Pro (worksheets are read-only), it’s easy to view Excel worksheets and do things like
- Join an Excel table to a layer attribute table, then use the Excel data for queries, field calculations, feature labels, or map symbols.
- Use Excel data as input to geoprocessing operations.
- Export Excel data to a geodatabase table so that it can be managed with and related to GIS data stored in the geodatabase.
ArcGIS Pro supports XLSX files (Excel 2007) and XLS files (Excel 2003 and earlier). Before working with Excel data in ArcGIS Pro, there are a few things you need to be aware of. Here are some common things to check. Continue reading

In ArcGIS Pro, the mapping module is called arcpy.mp. To try the snippets below for yourself, make a copy of an ArcGIS Pro project file (APRX) and move it somewhere for testing purposes. You don’t have to be an experienced Python scripter—simply enter the code below into the Python window and check out the results. Continue reading

Have you been meaning to try out the ArcMap Python window, but just aren’t sure how to start? Well, the five code snippets below are a great tool to familiarize yourself with the Python window and the arcpy.mapping module. Make a copy of an MXD file and move it somewhere to test out these snippets. You’ll soon see how useful a few Python tricks can be for map management tasks.
- Each snippet below works with ArcMap 10.x, an existing map document (MXD file), arcpy.mapping module, and Python 2.x.
You don’t have to know any Python syntax to use these snippets. Simply enter the code into the Python window and check out the results. Continue reading
In a previous post, we covered how to add data to ArcGIS Pro, prepare it for your project needs, time-enable the layer, then share the layer as a time-enabled web layer to an ArcGIS Online organizational site.
This post takes you through the steps to create a web map featuring the time-enabled web layer. The third post shows how to create a story map that features the web map.
- Go to www.arcgis.com and sign in to your ArcGIS Online organizational account.
- In My Content, right-click the web layer and add it to a new map.
You can immediately see that the web layer is time-enabled because a time slider displays at the bottom of the map viewer. Continue reading
This blog’s most popular post ever is about visualizing temporal data on a map. The ArcMap workflow described in that post is still valid. Five and a half years later, though, we have a tightly integrated platform and new options. An exciting new desktop app. Easy ways to share GIS-driven insights with a wide audience.
It’s time to give that post a modern refresh. We’ll use the same scenario as the original post: piracy incidents in and around the Gulf of Aden. Continue reading
For millions of homework- and test-weary youth in the USA, “June” is a magic word. It conjures the end of the school year and the start of sublime summer vacation. June is the month that students—laggards and high achievers alike—anticipate with glee. Not to mention teachers.
For non-teaching working adults, though, June is a continuation of routine—projects, meetings, to-do lists, and deadlines. For us, work doesn’t stop in June. And neither should learning.
That’s why we decided to share a different ArcGIS tip every day in June, thirty tips in all. We culled product documentation, GeoNet forums, blogs, and brains around the Esri landscape for practical info, tips, and tricks ArcGIS users can apply immediately. Continue reading
There are many ways GIS professionals can get their work done these days. Technology is providing new capabilities and, at the same time, the user experience is becoming simpler, more intuitive, and integrated. Case in point: ArcGIS Desktop, which now includes ArcGIS Pro and an ArcGIS Online organizational subscription.
ArcGIS Pro is associated with an ArcGIS Online organization and integration is built into the interface. You can directly publish content you create in ArcGIS Pro to the organization and easily grab content from ArcGIS Online to support mapping and analysis projects. Continue reading
After sampling the ArcGIS Pro geoprocessing environment, it was time to sit down for a meal. Mapping was on the menu. In ArcGIS Pro, there’s a lot about mapping to like and some things to love.
- Note: Membership in an ArcGIS Online organization is required to use ArcGIS Pro. Your organizational administrator will need to provision you with an ArcGIS Pro license.
Starter Course: The Interface
When opening their first ArcGIS Pro project, ArcMap users may experience something akin to a new-house sensation. Familiar furniture fills the rooms, but the new space has cast the pieces in an exotic light. Continue reading
Given that technology—the Internet, e-commerce, smartphones, the behemoth that is social media—has dramatically changed consumer and personal behavior over the last decade, it’s no surprise our professional lives have evolved. For many of us, what we do at work and how we do our work have changed a great deal.
At the same time, more and more organizational leaders have grasped the business value of getting geospatial content out of a department silo and into the hands of knowledge workers using ArcGIS Online and a variety of enterprise applications.
As a result, many GIS professionals are being asked to share. Of course, the profession as a whole is a generous lot, so sharing itself is nothing new. What’s new is the ease with which things can be shared.
The ArcGIS Online organization has become an integrated content platform that supports enterprise GIS workflows and the information needs of both GIS and non-GIS professionals, collaborative working groups, and the public.
When there are many potential content consumers, the question of what to share needs to be carefully considered. If you’re in the process of crafting a sharing strategy for your ArcGIS Online organization (or on-premise portal), here are three tips to help the process along.
This is the third post in a three-part series on creating geoprocessing models in ArcGIS.
If you’ve read the previous posts in this series, you’ve got modeling basics down and you know how to add model parameters to support easy reuse and scenario testing. In this post, you’ll learn some techniques to do more with less—effort, that is. Continue reading
