Yes, they can both read shapefiles and geodatabases but there is some additional functionality with the newer Pro version.

I’ll also discuss managing the data behind the scenes, all with the goal of making better sense of complex data.ArcGIS Pro is the new ArcMap: As Dave Ramsey likes to say "The paid-off home mortgage is taking the place of the BMW as the status symbol of choice", in the case of GIS software, ArcGIS Pro is taking the place of ArcMap as the desktop software of choice. I’ll highlight the binning techniques that give you additional control over bin drawing, symbology, and calculating additional statistics. In a future blog post, I will walk through the feature binning process using sample tornado data from the United States. To fully understand feature binning, I recommend reading the web help topics linked below for reference before jumping into it. An equal area projection for your data is strongly recommended. For example, your data must be a point feature class stored in an enterprise geodatabase such as SQL Server, PostgreSQL, or Oracle.
With these new capabilities, there are requirements regarding the type of data storage required, setting up the data, and managing updates to the data. The calculations and summations of the data are done when binning is first enabled.

This means the scale at which bins draw instead of points, the size, and symbology of the bins update on-the-fly without impacting drawing performance. With dynamic feature binning, there is no need to rerun tools-it’s dynamic. New map scales could not be visualized without rerunning the tools. This had to be done for every desired map scale, and there was no dynamism. Then you would perform additional data processing to assign values to each polygon. Previously you had to manually create bin layers (tessellations or fishnets) using various geoprocessing tools. However, the process has been improved greatly for ArcGIS Pro starting with the 2.4 release. The highest number of earthquakes occur over the Philippine Sea, near Timor, and the northwest coast of Sumatra.Įnabling dynamic feature binning on the feature class shows where earthquakes are most frequent.īinning techniques are not new to mapping or GIS. Using an unclassed color scheme, I can visualize the data for areas with high earthquake frequency. In the example below, the bins are symbolized with the total number of points in each bin. Once this is done, my ‘bin-enabled’ feature layer has two components: the underlying point features (like the image above), and the bin polygons (see below). You can view whether a point feature class has feature binning enabled by viewing the layer’s properties. To apply dynamic feature binning in ArcGIS Pro, I first enable feature binning on the feature class. You can aggregate points into bins for any type of data, but it is best suited for data that is not bound by political boundaries or preexisting geography. Bins are arbitrarily generated polygon frameworks that are used to summarize dense information. The high number of point features make it difficult to determine earthquake density in certain locations.ĭynamic feature binning takes the hundreds or millions of point features in this feature class and groups them into bins at multiple scales. It’s not the best mapping option for this situation, and in some cases, you may need to preserve the symbology of the points. How can we better explore this data? We could create a heat map, but the way heat maps interpolate and extrapolate data would show that Thailand is also heavily impacted by earthquakes. The high density could mean there are 5 – or 500 – earthquakes covered by one symbol. Beyond that, we can’t be sure how many points there are in certain spots. So many, in fact, that we can’t even see the Philippines under the morass of symbols. Even at this scale, there are too many points. The image below shows XY locations of recorded earthquakes for the entire world since 1900 and is zoomed in to Southeast Asia. Say hello to dynamic feature binning, a method of feature aggregation and a great way to visually represent point data.Īdded emphasis on ‘dynamic’: we’ll come back to this in a bit.įor now, take a moment to consider any data you use that is densely packed or contains millions of locations or points (for example, every recorded lightning strike in the world in the last 30 days.) When you first add data like that, it’s usually in the form of a feature layer and symbolized with a default point symbol. We are happy to introduce a new feature in ArcGIS Pro 2.4 to help simplify, summarize, and speed up data analysis. Hello there! My name is Greg and I am a Product Engineer for ArcGIS Pro.
