# Gravity-Visualization

This work seeks to visualize the work done by Hirt et al. (2019).

The Readme for their research is [here.](https://ddfe.curtin.edu.au/models/SRTM2gravity2018/SRTM2gravity_Readme.dat)

This project initially started by perusing the [GRACE Tellus Gravity Recovery & Climate Experiment](https://grace.jpl.nasa.gov/data/get-data/)

I also looked at data from:

* [Gravity Predictor Service](https://geodesy.noaa.gov/web_services/grav-d.shtml)

* [CSR Low-Degree Gravity Harmonics GRACE Satellite](https://filedrop.csr.utexas.edu/pub/slr/degree_5/CSR_Monthly_5x5_Gravity_Harmonics.txt)

* [National Centers for Environmental Information (NCEI)](https://www.ngdc.noaa.gov/mgg/gravity/)

# Output

## After

![Earth Mercator of Gravity](/images/earthGravity.png)

![3D Model of Gravity](/images/3dGravity.png)

![2D Model of Gravity](/images/2dGravity.png)

## Before

![Old 2D Model of Gravity](https://ddfe.curtin.edu.au/models/SRTM2gravity2018/data/FullScaleGravity/N00E060/N11E077_full.png)

# How To Use

Please type in the specific location you want and it will show a 3d Histogram and 2d Histogram with your results.

The 2D visualization of all possible locations is here.

# TODO

* Type in a latitude and longitude and it outputs automatically (if available) without searching for the link. In lieu of this, you may type the link by modifying the code. [All possible links are here.](/filenames.txt)

* The ability to input a square and it will concatenate the multiple location data files together and output the concatenated data

* Create Interactive Globe Model of this to try to imitate the [gravity potato](https://user-images.githubusercontent.com/22484328/223882296-e0e7e285-f51d-4bbb-9c21-b056ce6c29e6.png) Google Earth style

# Thanks

I want to thank (in no particular order):

* Cornelia Freund, Technical University Munich

* Dr. Christian Hirt, Technical University Munich

* Dr. Michael Kuhn, Curtin University

* Dr. John Ries, UT Austin

* Brian Meyer, NOAA

Without you, this project would have gone far more frustratingly
