Bathymetry around Kosrae (derived from AutoGrid)

Type  Raster Dataset

Tags

Summary

To show the bathymetry (depth to seafloor) around Kosrae.

Description

This dataset shows the bathymetry (depth to seafloor) around Kosrae. It was generated by AutoGrid(2019), a web application that creates grids and map images from multibeam bathymetry data. AutoGrid is a program by the National Oceanic and Atmospheric Administration (NOAA), National Centers for Environmental Information (NCEI, formerly NGDC).Island Research & Education Initiative (iREi) (2019) extracted a subset of the original dataset and formatted it for use in this atlas.

Lineage 

Lineage statement
There are three major steps in the AutoGrid application - build grid, create map images, and generate ASCII output files. AutoGrid uses MB-System and the Generic Mapping Tools (GMT) to perform these actions. The generated grid is a COARDS-compliant GMT netCDF format containing integer data. AutoGrid builds the grid in Geographic coordinates using the WGS84 horizontal datum and utilizes a Gaussian Weighted Mean as the gridding algorithm.

Process step

Description
1. Projected ASCII to WGS84 UTM Zone 58N and saved as TIFF file; 
2. Added metadata.
