This post introduces simple BRDF modelling (i.e. how can we account for the variation in surface reflectance due to acquisition geometry?) using some MODIS data. You can find the whole post in wakari. If you accept to not escape the HTML & JS, you will find a link to the ...

So a quick post on how to get access the web-based data on rider timings for the RideLondon event. The idea is that you can access the cyclist timings, and then maybe do some statistics (or boost/depress your morale by looking at how your time compares to the wider ...

MODIS products are usually provided as data granules, representing the magnitude of interest (plus a number of different extra layers of metadata, quality assurance flags, etc) over a given temporal period for an area typically extending 1200 by 1200 km in the MODIS sinusoidal projection, around 10x10 degrees. Typically, your ...

Let's say one wants to find out a box around a given latitude/longitude point. How to do this without GIS software using an artisan UNIX approach? Hell, if it works for coffee! The steps are as follows:

1. Convert the centre point into UTM so we have meters rather ...

Recently, the USGS has closed their FTP download service for MODIS products, such as LAI, surface reflectance, etc. This is quite annoying, because I had a nice wget script that no longer works... So I decided to code a simple downloader in python that woud supersede my previous hacked together ...
