This project began as I wanted to have easy access to data that I find useful in a modern cloud native format.
Most of the data covers Northern Ireland, is sourced from Open Data NI, and is predominently LiDAR or bathymetry data.
The data is provided as Cloud Optimized GeoTIFF; this format is a relatively new OGC standard adopted in October 2023.
There is more information on Cloud Optimised GeoTIFF? on the data formatspage. For further information on the format and why you should store and serve your raster data in Cloud Optimized GeoTIFF format then the https://cogeo.org will provide you with all the information you need.
The python code to convert data can be found on github. This code is provided as-is. If you just want to get started with Cloud Optimized GeoTIFFs, the following is an example of how to convert a file (e.g. a TIFF, VRT etc) into a COG with GDAL.
import os
from osgeo import gdal
input = r'input.vrt'
output = r'output_file.tif'
translate_options = gdal.TranslateOptions(format='COG', creationOptions=["COMPRESS=DEFLATE", "NUM_THREADS=ALL_CPUS"],
outputSRS='EPSG:29902')
gdal.Translate(output, input, options=translate_options)
This site is provided as-is. It can be viewer at https://better-open-data.com and at https://geoawd.github.io/better-open-data/. It may not have 100% uptime; I might temporarily break things while trying to improve the map viewers or the data. If you have any suggestions please get in touch.
