I’ve been teaching GeoPython recently to beginners – still places on courses in September (GeoPython for beginners and Git for beginners – early bird rates for August). We do alot of foundational work in order to open the doors to then start doing impactful things with Python. The topic that seems to get most people… Read More »In praise of GeoPandas.explore
Just finished the July course and already had some great feedback ‘Excellent couple of days, thank you very much! Learnt loads!’ ‘I think you use the resources in a fantastic way the course is great and we leave with a lot of insights’. ‘Thank you very much Andrew! Really interesting and useful course. Thanks.’ ‘Was… Read More »New date for Geo Python course. 20th and 21st September 2022

This blog is loosely a transcipt from the scenefromabove podcast season 12 episode 6. You can listen to it below. These, though, are my opinions. Background When we started doing the podcast in Dec 2017 we were raving about Google Earth Engine (GEE) and if you’d asked me what Microsoft were doing in the Earth… Read More »GEE vs Planetary Computer
I’m writing a series of irregular short posts on some tips and tricks on using Geospatial Python. They may not be best practice, but I hope they are of help. I’ll try and give some context to when I’ve used the ‘tip’. Convert your command scripts to a GUI easily. Frequently I’ve been asked ‘should… Read More »Tips and Tricks #5 convert cmd line to GUI easily

I’m starting a new series of irregular short posts on some tips and tricks on using Geospatial Python. They may not be best practice, but I hope they are of help. I’ll try and give some context to when I’ve used the ‘tip’. First up, interoperability.

Way back in Feb 2019 I wrote a series of posts on Geospatial Julia and here they all are: Julia for Geospatial Programming part 1 – setting up Julia for Geospatial part 2 – speed test Julia for Geospatial part 3 – reading, displaying and writing raster data The good news is that for the… Read More »Julia part 4
This post was my ‘script’ from the scenefromeabove S11E6 podcast. If I have missed something it is entirely on me, this gives perhaps a 5% flavour of the Earth Observation world. I have not included all the links, the ones included are at random. If missed please do go back and look at the show… Read More »2021 year in review – scenefromeabove
Quite often I get sent / send shapefiles (zipped up mostly). I wondered if there was any way of reducing the filesize, sometimes these files can get quite big! In this notebook I wanted to run some checks / experiments on whether I could reduce the size of a shapefile. I tried various options, simplifiying… Read More »Reducing Shapefile size
I’ve been writting a lot recently about STAC, COG and Python. These are some of my recent posts: COG and Landsat in QGIS COG and Landsat with Python STAC, COG, Python and QGIS Smiley Face, STAC and COG I am very much aware that the majority of work with Earth Observation data is still within… Read More »Building virtual rasters from STAC
This is a light hearted post which hopefully you find fun. Let’s take a png of a (hand drawn!) smiley face and hide it in Satellite images that I have streamed as a Cloud Optimized Geotiff and found via a SpatioTemporal Asset Catalog (STAC). We are going to be using this 2kb png and hiding… Read More »Smiley Face, STAC and Cloud Optimised Geotiffs
I’ve spent a lot of time in the past trying to find satellite data. What the SpatioTemporal Asset Catalog (STAC) does is to build a common specification for how Satellite images (read Assets, they can include other things like drone imagery) are queried and found online. Why should we care about this? Well, for a… Read More »STAC, COG, Python and QGIS
