What do you think you will learn when reading this title? Real-estate? Gold? A number of years ago I came across this study about the "million dollar blocks" and found it fascinating. This is a really nice example of how geography and spatial analysis are so useful for bringing to life data and really gaining insights … Continue reading “Million dollar blocks”
Mapping genomic data
Screenshot of nextstrain By reconstructing a phylogeny we can learn about important epidemiological phenomena. By adding geography to where the sample was taken we can map the spatial spread of a pathogen as well as how it may be changing in a certain location. By looking at this in context by adding in different geographies … Continue reading Mapping genomic data
Where are the rainforests located?
Earlier we posted a short article about using annual rainfall to identify deserts. Now we will use rainfall to identify rain forests. In this case a rain forest is defined as locations where rainfall is greater than 2000mm a year. Temperatures are also important but for now we are just interested in defining rainforests based … Continue reading Where are the rainforests located?
The return of the hummingbird
One of the highlights of the year after a long cold winter is..... the return of the hummingbird. The arrival of the hummingbirds signifies the end of winter and the start of the hot steamy summer! Thanks to a number of different websites where citizens, who like to keep tabs on the world outside of … Continue reading The return of the hummingbird
Temperatures and how they relate to plants in the garden
As summer slowly approaches and one starts to think about the garden and the plants to select for the garden, an important consideration is temperature. Depending on where you live, you will want to select a proportion of plants that will survive from one year to the next, otherwise you will constantly be replacing plants, … Continue reading Temperatures and how they relate to plants in the garden
Suitability Analysis
Recently I was putting together a short tutorial where the participants were going to use a suitability analysis approach to create a map. During the process I realised that I had not explained this process clearly so here is my short post about suitability analysis. Suitability mapping methods (also known as overlay or multi-criteria decision … Continue reading Suitability Analysis
Interpolation Methods for spatial data
Spatial Interpolation Methods For those of you new to interpolation methods. Interpolation is a procedure used to predict the values at locations that lack sampled points. It is based on the principle of spatial autocorrelation or spatial dependence (e.g. Tobler’s First Law of Geography), which measures degree of relationship or dependence between near and distant … Continue reading Interpolation Methods for spatial data
Spatial data analysis: overview of the 6 function classes
In an earlier post I provided an overview of the different types of methods that might be used to conduct different types of spatial data analyses. These included using statistical methods, spatial analysis methods, data science methods and depending on your needs and use of imagery, image analysis methods. In this post I will go … Continue reading Spatial data analysis: overview of the 6 function classes
the geospatial ecosystem: Software, Libraries and Data Platforms
With more than 30 software packages to choose from to perform a range of analyses, where does one start? What software or data platforms, programming languages and libraries? To get you started see the image below where I have provided an overview of GIS and EO (Earth Observation) software tools, libraries in R and Python and … Continue reading the geospatial ecosystem: Software, Libraries and Data Platforms
Spatial Data Science vs GIS vs Geospatial?
Heard about GIS (Geographic Information System), GIScience, Spatial Data Science, Geospatial information and technologies? Wondering what it is all about? Let's start with some background info. GIS - Geographic Information System is a system that enables you to create, edit, organise, work with and analyse spatial information. It is a very powerful tool that not … Continue reading Spatial Data Science vs GIS vs Geospatial?
