This is a quick write up that’s related to the blog series I’m doing on custom symbology in ArcGIS Pro. Well sort of, it just so happens to be the perfect dataset to use to use for UK based mapping projects where you don’t want to use a costly licenced dataset (maybe the forthcoming Open MasterMap may change that?). Now, I know I normally write about 3D and CityEngine related stuff but I do love a good 2D map as well! This post assumes a simple working knowledge of ArcGIS Pro. I’m considering making this a video as well so you can see the entire process.
First you need to download the OS Open Zoomstack as a ‘geopackage’ don’t worry whilst ArcGIS Pro doesn’t support direct editing of a ‘geopackage’ it does support native reading of it. * there’s some discussion in the comments at the end of this post, if you’re reading on the front page click here to view
Fun fact: the GeoPackage is an ‘open format for geospatial information’You can read about it here.
A word of warning this is a UK national dataset, so naturally the size is large (10.1 Gigabytes!).
To help as well I suggest you download the Ordnance Survey’s custom symbology for this dataset which you can get from github.
- Download for QGIS, Esri etc all style templates here.
- Or directly down the styles here.
- Instructions for using these styles on the Zoomstack Geopackage in ArcMap and QGIS can be found here. (PDF)
As you can see there are some instructions on what to do with style sheets if you’re an ArcMap user in that PDF linked above… well I do not use ArcMap much anymore more so I’ve pretty much made a complete transition to ArcGIS Pro so here’s what you do next.
Step 1: New ArcGIS Pro project and then ‘insert’ a new ‘map’.
Step 2: Convert the Geopackage into a File Geodatabase… as far as I am aware you don’t need an Advanced licence or FME or the Data Interoperability Extension (if I’m wrong comment below on this post) you can drag in each layer manually into a Map in ArcGIS Pro and then right-click the ‘export data’ function. Or better yet, you can use the copy features GP tool (using the Batch function). *I’ve created a toolbox with two tools that simplifies this process for me. I will share this as a separate blog post soon…
Step 2: Remove the prefix ‘main_’ from all the feature classes you imported into the new file geodatabase, otherwise you can’t use the lyr file on them….
Step 3: Find your “OS-Open-Zoomstack.lyr” (link to download it here) and drag it in to your Map, notice all those red “!” marks, this means it can’t find the data these symbols are linking too. Click on one of these red “!” to fix them all. It will ask you where the data layer is located ( in this case ‘names’). Find the data in the new file geodatabase you created.
Step 4: Well it should all work and all those “!” should have gone and you have a nicely symbolised OS Open Zoomstack data set courtesy of the nice folks at the Ordnance Survey.
A final note this workflow unbelievably helped me find where Esri hid the ‘repair data’ function went, basically they built it into the “!“… d’oh.
