Overview

Caribbean - Single-beam bathymetry

This dataset is a compilation of several single-beam bathymetry surveys of the Caribbean ocean displaying a wide range of tectonic activity, uneven distribution, and even clear systematic errors in some of the survey lines.

The original data file was compressed with LZMA to save space and make it possible to upload it to this GitHub repository (see raw/) since there is not direct download link we could use.

Changes made

These are the changes made to the original dataset.

Convert from MGD77 to a simpler compressed CSV format.
Retain only the survey ID, coordinates, and depth.
Cut the data to a slightly smaller region.

About this repository

This is a place to format and prepare the original dataset for use in our tutorials and documentation.

We include the source code that prepares the datasets for redistribution by filtering, standardizing, converting coordinates, compressing, etc. The goal is to make loading the data as easy as possible (e.g., a single call to pandas.read_csv or xarray.load_dataset). Whenever possible, the code also downloads the original data (otherwise the original data are included in this repository).

💡 Tip: The easiest way to download this dataset is using Pooch, particularly to download straight from the DOI of a release.

Comments

Add track information to the bathymetry data

This info usually comes into play during processing but we're not capturing it right now. Check if the original data has it and include it in the derived product.

Any help doing this would be more than welcome!

CDIoU and CDIoU loss is like a convenient plug-in that can be used in multiple models. CDIoU and CDIoU loss have different excellent performances in several models such as Faster R-CNN, YOLOv4, RetinaNet and . There is a maximum AP improvement of 1.9% and an average AP of 0.8% improvement on MS COCO dataset, compared to traditional evaluation-feedback modules. Here we just use as an example to illustrate the code.
