GEE vs Planetary Computer

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

Tips and Tricks #3 improve Machine Learning with multiple inputs from a single image

  • blog

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’. Using many image processing techniques for input When you are building your machine… Read More »Tips and Tricks #3 improve Machine Learning with multiple inputs from a single image

Reducing Shapefile size

  • blog

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

STAC, COG, Python and QGIS

  • blog

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

Training data and Satellite data

  • blog

I don’t think I have come across a GitHub repo any code while looking for more resources to add for awesome-eo-code that is related to evaluating training data for Satellite imagery. I have often wondered how someone new to the industry could make their mark. In a sector that has focused a great deal of… Read More »Training data and Satellite data
