Wonder if it is possible to have an earth-api using Earth Observatory - Anyone want to investigate how possible this might be?

Hi, I am interested with this.
I will take time to investigate on weekend.

[vn7n24fzkq]

I found a way to get picture like apod-api.

• step1 : Get images.
  Use this url with GET method and timestamp parameters

    https://earthobservatory.nasa.gov/images/getRecords?filters=null&dateStart={timestamp}&dateEnd={timestamp}

The response will looks like this

{
    "current_page": 1,
    "data": [
        {
            "id": 146225,
            "title": "Flood Waters Overwhelm Northern Madagascar",
            "caption_short": "Parts of the island nation saw double the usual amount of monthly rainfall.",
            "thumbnail_file": "madagascar_oli_2020027_th.jpg",
            "guid": null,
            "post_date": "2020-01-30 13:43:07",
            "type": "image",
            "image_path": "https://eoimages.gsfc.nasa.gov/images/imagerecords/146000/146225/",
            "slug": "/images/146225/flood-waters-overwhelm-northern-madagascar",
            "date_raw": "2020-01-30 13:43:07",
            "date_formatted": "Published Jan 30, 2020",
            "type_display": "Image",
            "topics": {
                "imageofday": "Image of the Day",
                "land": "Land",
                "water": "Water",
                "floods": "Floods",
                "human": "Human Presence",
                "landslides": "Landslides"
            }
        }
    ],
    "first_page_url": "https://earthobservatory.nasa.gov/images/getRecords?page=1",
    "from": 1,
    "last_page": 1,
    "last_page_url": "https://earthobservatory.nasa.gov/images/getRecords?page=1",
    "next_page_url": null,
    "path": "https://earthobservatory.nasa.gov/images/getRecords",
    "per_page": 5,
    "prev_page_url": null,
    "to": 1,
    "total": 1
}

• step2 : Get page data

Get first data in data array, maybe the topics contains "Image of the Day" ?

Now, you can get thumbnail image by use image_path append with thumbnail_file.

The page url is the api host append slug
Should looks like this.

https://earthobservatory.nasa.gov/images/146225/flood-waters-overwhelm-northern-madagascar

Get the page

• step3 : Find the image we want

Parse the html and find the element contains class="download-btn download-btn-first no-underline pull-right hvr-rectangle-out" and the href value is the image url.

Excellent work @vn7n24fzkq -

Anyone attempted to check if this pattern holds across many dates ?

[JustinGOSSES]

@vn7n24fzkq can you provide the format of the timestamp you got to work? I put in a variety of timestamp formats but none of them seemed to be the right one.

[vn7n24fzkq]

@JustinGOSSES I use uinx timestamp like this site provide. https://www.unixtimestamp.com/index.php
If I use timestamp start at 01/01/2012 @ 12:00am (UTC) to 02/01/2012 @ 12:00am (UTC), it would be https://earthobservatory.nasa.gov/images/getRecords?dateStart=1325376000&dateEnd=1328054400

FYI for everyone, the earth-imagery API on api.nasa.gov has been open-sourced here: https://github.com/nasa/earth-imagery-api
