geoblaze -- a command line interface for blazing fast raster analysis

SYNOPSIS

  • geoblaze identify <georaster> <point>
  • geoblaze id <georaster> <point>
  • geoblaze max <georaster> [geovector]
  • geoblaze min <georaster> [geovector]
  • geoblaze mean <georaster> [geovector]
  • geoblaze median <georaster> [geovector]
  • geoblaze mode <georaster> [geovector]
  • geoblaze sum <georaster> [geovector]
  • geoblaze version

DESCRIPTION

GeoBlaze CLI is an open-source command line interface to the GeoBlaze JavaScript Raster Processing Engine (geoblaze.io). It allows you to do simple basic aggregate statistics like, mean, median and mode while only typing one line. You can also use it to simply run band arithmetic like NDVI and save the result to a file.

OPTIONS

  • identify, id: Get the value of the pixel at the specified point. The Point should be specified as a longitude and latitude pair "-40,20"
  • max: Get the highest value in the raster, ignoring no data values.
  • min: Get the lowest value in the raster, ignoring no data values.
  • mean: Get the mean average of pixel values in a raster. You can optionally specify a geovector file, like a geojson or a shapefile, so the calculation is only run on the pixels of the raster inside of the vectors.
  • median: Get the median average of pixel values in a raster. You can optionally specify a geovector file, like a geojson or a shapefile, so the calculation is only run on the pixels of the raster inside of the vectors.
  • mode: Get the most common pixel value in a raster. You can optionally specify a geovector file, like a geojson or a shapefile, so the calculation is only run on the pixels of the raster inside of the vectors.
  • sum: Get the sum of pixel values in a raster file. You can optionally specify a geovector file, like a geojson or a shapefile, so the calculation is only run on the pixels of the raster inside of the vectors.
  • version: Show version, which is found in the package.json
