Astro-grid is a simple display of the data contained in the minor planet center orbit files.

You can select which dimension to use on each axis using the select boxes at the top of the page.

The graph shows each dimension with the colour indicating the number of asteroids in that cell.

You will need a working go installation. You should be able to get this from your package manager or the golang website. Make sure your GOPATH is set.

You will also need a copy of the minor planet center orbit file

git clone https://github.com/wselwood/astro-grid.git
cd astro-grid
mkdir ./data
go build
./astro-grid -in $path_to_mpcorb.dat.gz -out ./data

Now open index.html in your browser.

main.go contains the main loop.

dimensions.go defines the dimensions. Each Dimension has an extractor which defines how to get the data from a minor planet record.

extractors.go defines the extractors. This must define two things, how to find the cell for a given value and how to find the base value for that cell. Tests are in extractors_test.go

grid.go contains the data structures that back the result grids while processing.

index.html contains the rendering code for the visualization. This uses D3.
