A toy prototype to test the logic flow of the indicatively mapped proposal.

A toy script to replicate (somewhat) the functionality of the
[GMT Blockmedian](https://docs.generic-mapping-tools.org/latest/blockmedian.html) utility.

The main difference is that a grid is pre-determined, which avoided the grid edge "buffering" GMT does.

Documenting a potential issue when attempting to do TileDB versioning from GDAL and PDAL.

gdal_translate to an existng TileDB array but opening with a specific timestamp results in fail.

PDAL with a writers.gdal to an existing TileDB array, again with a specific timestamp results in a fail.

The general idea is to continually update the density grid as additional pointcloud datasets get
added to the centralised pointcloud.

The desired output can be generated by outputting independent grids, and pulling them

Sample code for tiledb data ingestion to be used as input into cellular density calcs.

This toy script was put together to assist in trawling some imagery and building a small catalog.

In the attached data table, you have a set of 12 differential InSAR observations ("obs" in units of millimetres) 
for a single pixel observed over a patch of ground undergoing a periodic surface movement signal.

The InSAR observations are formed from 11 SAR images collected by the Sentinel-1A satellite at regular 12 day intervals.
First and second epochs for each InSAR observation are given in the attached table ("epoch1" and "epoch2").

Write and submit some code (in the language of your choice) to re-construct the periodic ground surface movement signal
from the InSAR observations.

Toy script for looking at average geometric accuracy of USGS Landsat Collection-1.

The geometric accuracy, whilst subjective, is retrieved from the metadata.

This example is only retrieving the CEP90 (Circular Error Probable) calculated by eugl, which itself is harvesting information
calculated by gverify (Tool developed by Pinkmatter).
