I was recreating the ArcPy Feature Vertices to Points tool using GeoPandas and Shapely and I was unimpressed with the length of time it took to perform against its ArcPy counterpart when it came to processing dangles. However, that was until I applied a spatial index to the workflow, which rapidly sped up matters. Rapidly …

If you head over to the ArcPy page you will find a couple of custom toolboxes that we have been creating. These are great, you can access via ArcGIS Pro and use to perform their intended tasks. But what if you want to add these to chained workflows in a Python script? There’s a very …

You may come across a couple of scenarios…1. You have published a hosted feature service to ArcGIS Online (AGOL) with domains and the dataset has matured with edits. You do not want unshare, export, download, and republish to overwrite the feature service but you need to update the split/merge policy to make edits easier and …
The Sort (Data Management) tool has limited functionality on a Basic and Standard licence, you can only sort by one field and cannot use a spatial sort. We saw in this blog post how we can use the Export Features (Conversion) tool to sort a feature class or table by multiple fields, unfortunately that Export …

The Create Random Points (Data Management) tool is available with an Advanced license or on a Basic or Standard license if you have 3D Analyst or Spatial Analyst. In this post we will look at creating the tool for use with a Basic license. We’ll keep it simple for now and just generate the desired …

I remember being thrown into the deep end when it came to using ArcPy. The manual tasks were racking up, the human errors in a long-winded workflow were being compounded by fatigue, and let me tell you, it took about 60-90 hours to complete one of the workflows, waiting for the output from one geoprocessing …

This became a pet project of mine back in 2017 where I first implemented using open source geospatial Python modules, osgeo and shapely. I then converted the workflow to ArcPy before Esri had brought out the Generate Points Along Lines tool. This third iteration of the workflow uses the Generate Points Along Lines tool to …
A common task is to calculate the percentage overlap between a polygon feature class overlaying another polygon feature class. One general workflow is to use the (Pairwise) Intersect tool with the Join Attributes parameter set to Only feature IDs, add a field to store the percentage overlap attributes, join the underlay polygons to the output …

Not the most fanciest of tools but another one none-the-less that you can by-pass the Advanced license requirement and create your own tool using ArcPy. The Feature Envelope To Polygon (Data Management) is only available in ArcGIS Pro with an Advanced license. You can achieve quite similar to this tool using the Minimum Bounding Geometry …

The Table to Excel tool from the Conversion toolbox is a stalwart amongst Geoprocessing tools but it does have its limitations, namely; you cannot subset the records directly with the tool itself, you cannot subset the columns to be exported and the order that you want them in the spreadsheet, and you cannot sort the …
