Photos Database API

Introduction

The photos database contains information about astronaut photography of Earth that is available on this website. This API provides for submitting queries to that database and getting the results of those queries.

The Photos database API is a web script that accepts HTML form inputs using either GET or POST methods to get the database query parameters and fields to return and returns the results in JSON format.

Database Tables and Fields

In order to use the API, you need to use database table and field names and understand what sort of data are available for each table. The database tables and fields that this API uses are listed below along with explanations of each.

Some of the field descriptions refer to a "nadir point". That is the point on the Earth directly below the spacecraft when the photo was taken.

The mission, roll and frame fields in each table are the key fields used to relationally link the tables by the API. So the format and descriptions for those are the same for each table.

frames Table

The frames table holds records for photos that have been cataloged by humans. The fields in the table contain the metadata results from cataloging. Most of the photos in the database are not cataloged and so will not have records in this table.

Field	Description
mission	This is the spaceflight mission the photo was taken on. It is part of the photo identifier, which consists of mission-roll-frame.
roll	This is the designator for the roll of film the photo is on for film cameras or for electronic cameras it is "E". This is part of the photo identifier.
frame	This identifies the photo within the roll. It is usually a number but sometimes has letters. It is part of the photo identifier.
tilt	This describes the tilt of the camera with respect to the Earth. Possible values are "NV" for near vertical, "LO" for low oblique, "HO" for high oblique or a number that is the positive angle in degrees between a line pointing down to the Earth and line from the lens to where the lens is pointing on the Earth.
pdate	This is the UTC date the photo was taken in YYYYMMDD (YYYY = year, MM = month 01-12, DD = day of month) format.
ptime	This is the UTC time the photo was taken in HHMMSS (HH = hour 00-23, MM = minute, SS = second) format.
cldp	This is the percentage of cloud cover. Some of these represent ranges, namely 10 represents 0-10, 25 11-25, 50 26-50, 75 51-75,100 76-100, although there are values in-between as well.
azi	This is the azimuth angle in degrees clockwise from north to where the sun is.
elev	This is the elevation angle in degrees from a plane tangent to the nadir point to where the sun is. Positive values are above the plane and negative values are below it. So this is useful for filtering based on how much sunlight was in the photo.
fclt	This is the focal length of the lens in millimeters.
lat	This is the degrees of latitude (-90 to 90) of the center point of the photograph. Values are stored to the tenth of a degree.
lon	This is the degrees of longitude (-180 to 180) of the center point of the photograph. Values are stored to the tenth of a degree.
nlat	This is the degrees of latitude (-90 to 90) of the nadir point. Values are stored to the tenth of a degree.
nlon	This is the degrees of longitude (-180 to 180) of the nadir point. Values are stored to the tenth of a degree.
camera	This is a two-characters code used to identify the camera. See Values for camera Found in the frames Table for a list of these.
film	This is a code used to identify the media used by the camera. See Values for film Found in the frames Table for a list of these.
geon	This is the geographic name for what the photo is taken of. A standardized list is used although the list is changed when country names change and past photos cataloged prior to the name change are not changed to the new name since it doesn't apply to the time when the photo was taken.
feat	This contains features identified in the photo.

images Table

The images table hold records for each image file we have in the database for the photos, one record per image. Each photo can have any number of images. Records for thumbnails are not included.

Field	Description
mission	This is the spaceflight mission the photo was taken on. It is part of the photo identifier, which consists of mission-roll-frame.
roll	This is the designator for the roll of film the photo is on for film cameras or for electronic cameras it is "E". This is part of the photo identifier.
frame	This identifies the photo within the roll. It is usually a number but sometimes has letters. It is part of the photo identifier.
directory	This contains part of the directory path to where the image file is located.
filename	This is the name of the image file. No path information is included.
width	This is the width of the image in pixels.
height	This is the height of the image in pixels.
annotated	This flags whether or not the image has been annotated. "Y" means yes it has and "N" means no it has not.
cropped	This flags whether or not the image has been cropped. "Y" means yes it has and "N" means no it has not.
filesize	This is the size of the image file in bytes.

nadir Table

The nadir table hold spacecraft position and sun position information at the time the photos were taken for photos that have not yet been cataloged. When photos are cataloged, record for the photo is removed from this table and merged into the frames table.

Field	Description
mission	This is the spaceflight mission the photo was taken on. It is part of the photo identifier, which consists of mission-roll-frame.
roll	This is the designator for the roll of film the photo is on for film cameras or for electronic cameras it is "E". This is part of the photo identifier.
frame	This identifies the photo within the roll. It is usually a number but sometimes has letters. It is part of the photo identifier.
pdate	This is the UTC date the photo was taken in YYYYMMDD (YYYY = year, MM = month 01-12, DD = day of month) format.
ptime	This is the UTC time the photo was taken in HHMMSS (HH = hour 00-23, MM = minute, SS = second) format.
lat	This is the degrees of latitude (-90 to 90) of the nadir point. Values are stored to the tenth of a degree.
lon	This is the degrees of longitude (-180 to 180) of the nadir point. Values are stored to the tenth of a degree.
azi	This is the azimuth angle in degrees clockwise from north to where the sun is.
elev	This is the elevation angle in degrees from a plane tangent to the nadir point to where the sun is. Positive values are above the plane and negative values are below it. So this is useful for filtering based on how much sunlight was in the photo.
cldp	This is the percentage of cloud cover. Since this cannot be programmatically determined based on time as the other fields, it is determined using machine learning. Unlike cloud percentages determine by humans, which can be tied to ranges as described above in the frames table, these are not tied to ranges.

camera Table

The camera table holds camera information for photos that are not yet cataloged. Records are removed from this table when the corresponding photos are cataloged.

Field	Description
mission	This is the spaceflight mission the photo was taken on. It is part of the photo identifier, which consists of mission-roll-frame.
roll	This is the designator for the roll of film the photo is on for film cameras or for electronic cameras it is "E". This is part of the photo identifier.
frame	This identifies the photo within the roll. It is usually a number but sometimes has letters. It is part of the photo identifier.
fclt	This is the focal length of the lens in millimeters.
camera	This is holds make, model and serial number if available for the camera. Unlike the the camera field in the frames table, this is not linked to a code that indexes the camera description.

captions Table

The captions table contains the captions people have written for the photos. Most photos do not have captions. This table also holds short one-line captions for photos cataloged by schools that identify which school cataloged the photo.

Field	Description
mission	This is the spaceflight mission the photo was taken on. It is part of the photo identifier, which consists of mission-roll-frame.
roll	This is the designator for the roll of film the photo is on for film cameras or for electronic cameras it is "E". This is part of the photo identifier.
frame	This identifies the photo within the roll. It is usually a number but sometimes has letters. It is part of the photo identifier.
caption	This is the caption. These use HTML tags for formatting with line breaks rather than containing line break characters. So the text for each caption is stored in a string without line breaks.

mlfeat Table

The mlfeat table holds features determined using machine learning. This website labels photos as "Cataloged By Machine Learning" if any of the features here are not "PAN-". The "PAN-" feature means that the photo contains the horizon.

Field	Description
mission	This is the spaceflight mission the photo was taken on. It is part of the photo identifier, which consists of mission-roll-frame.
roll	This is the designator for the roll of film the photo is on for film cameras or for electronic cameras it is "E". This is part of the photo identifier.
frame	This identifies the photo within the roll. It is usually a number but sometimes has letters. It is part of the photo identifier.
feat	This is a list of features found by machine learning. Items in the list are separated from each other by a comma followed by a space.

mlcoord Table

The mlcoord table holds center points of photos determined using machine learning for those photos that have had their center points determined this way.

Field	Description
mission	This is the spaceflight mission the photo was taken on. It is part of the photo identifier, which consists of mission-roll-frame.
roll	This is the roll of film the photo is on for film cameras or for electronic cameras it is "E". This is part of the photo identifier.
frame	This identifies the photo within the roll. It is usually a number but sometimes has letters. It is part of the photo identifier.
lat	This is the degrees of latitude (-90 to 90) of the center point.
lon	This is the degrees of longitude (-180 to 180) of the center point.
orientation	This is the clockwise angle in degrees from photo upwards direction (vector from lower left to upper left corner of image) to geographic north. This was determined using the image for the photo that is under the ESC\large folder.
resolution_long, resolution_short	This is the average spatial resolution of the large (full size) ESC (found under the ESC folder) image along the short/long side in meters per pixel. Pixels throughout an image are not uniform in resolution, so the reported value is averaged over the entire image in the defined direction.
ul_lat, ul_lon, ur_lat, ur_lon, ll_lat, ll_lon, lr_lat, lr_lon	These are the upper left (ul), upper-right (ur), lower-left (ll) and lower-right(lr) latitudes (lat) and longitudes (lon) of the image (can be used to build an image footprint/extent). These were determined using the image for the photo that is under the ESC\large folder.

publicfeatures Table

The publicfeatures table holds features identified by image detectives. Image detectives are members of the public that use our website to help us identify photos.

Field	Description
mission	This is the spaceflight mission the photo was taken on. It is part of the photo identifier, which consists of mission-roll-frame.
roll	This is the designator for the roll of film the photo is on for film cameras or for electronic cameras it is "E". This is part of the photo identifier.
frame	This identifies the photo within the roll. It is usually a number but sometimes has letters. It is part of the photo identifier.
features	Features found in the photos that are identified by image detectives are here. The convention is to separate them with commas.

How to Use the API

Using the API is done by sending an HTTPS request to eol.jsc.nasa.gov/PhotosDatabaseAPI/PhotosDatabaseAPI.pl. Three arguments are supported and all are required:

query Argument

The "query" argument consists of items separated with pipes (|). The items are treated as groups of four subitems, one group for each query parameter. The subitems are these:

table - This is the database table this query parameter pertains to as shown in the Database Tables and Fields section.
field - This is the field in the database table this query parameter pertains to as shown in the Database Tables and Fields section.
operator - This is the operator used for this query parameter. Here's the possible values of operator:
- gt - The left operand (the field) is greater than the right operand (the value)
- ge - greater than or equal to
- lt - less than
- le - less than or equal to
- eq - equal to
- ne - not equal to
- like - This is used to find strings within fields. The wildcard character supported in the value field is the asterisk (*). As an example, this operator used with a value of "*foo*" will find records in which the field contains "foo" anywhere in its value.
- not like - Like "like" but the negation of it. e.g. "not like" with a value of "*foo*" will find records that do not have "foo" in its value.
value - This is the right-side operand for the query parameter, or in other words the item used to compare the "field" to using the "operator". The characters that are allowed in this field are these:
- letters (a-zA-Z)
- number digits (0-9)
- the space character ( )
- asterisk (*) (This is the wildcard character when using the "like" or "not like" operators.)
- dash (-)
- period (.)
- comma (,)

return Argument

The "return" argument consists of items separated with pipes (|). The items are treated as groups of two subitems, one group for each item to be returned by the query. The subitems are these:

table - This is the database table the field to be returned resides in as shown in the Database Tables and Fields section.
field - This is the field in the table to be returned as shown in the Database Tables and Fields section.

key Argument

We use the key to track and control API usage. API keys are free. You can email us to request one.

Items are returned as JSON.

HTTPS requests can be sent using web browsers, scripts, or other software capable of getting web pages, such as curl or wget. This API supports both GET and POST types of requests.

GET requests occur when the arguments are specified in the URL. They start after a question mark (?) at the end of the address, are separated by an ampersand (&) and consist of a variable name followed by an equal sign (=) followed by a value. For example, https://some.web.path?vara=foo&varb=bar would be a GET request to https://some.web.path with two arguments: 1) "vara" with a value of "foo" and 2) "varb" with a value of "bar".

POST requests do not have their arguments in the URL but rather they are in the body of the HTTP request. The data are formatted the same as in the GET requests in that it consists of variable=value pairs separated with ampersands (&).

Some considerations:

All the specified query parameters must be satisfied for each photo record in order for it to be returned. In other words, the query parameters are joined with "AND" logic.
If multiple tables are specified in the "return" list then records must exist for the photo in each of those tables regardless of whether or not the tables in the "query" list use those tables. This is because an inner join is used to combine tables.
Lower case letters are required for argument variable names, table names, field names and operators passed in the arguments.
The case of the letters in the "value" parts of the "query" argument does not matter since the queries are not case-sensitive.
The order in which fields are listed in "return" argument has no bearing on the order they are listed in the returned JSON nor is there any guaranteed order from query to query.

Examples

These examples are shown using the URLs and so use the GET method. The method for using the POST method depends on which software you are using to send the request. For software like curl and wget it involves passing the text after the question mark as the POST data argument in the software you are using.

This API returns JSON that is not pretty-formatted. In other words, there are no added line breaks nor whitespace to make it look pretty; it is returned all on one line. In order to show the results in the examples below, the output has been formatted by a JSON formatter in order to get the prettier/human friendly version.

This example gets the directory and file name of images for uncataloged photos taken on May 1 2022 UTC.

Getting Images

Images can be downloaded by forming URLs to the images using the "directory" and "filename" fields of the "images" table from the API query results and then using software that is capable of downloading images given the image URLs.

URLs to database images have this form: https://eol.jsc.nasa.gov/DatabaseImages/images.directory/images.filename where images.directory and images.filename are the values returned by the API as shown in the examples above.

For example, if the JSON for a photo record is this:

	{
		"images.directory": "ESC/large/ISS067",
		"images.filename": "ISS067-E-34710.JPG"
	}

Then the URL to the image would be this:

https://eol.jsc.nasa.gov/DatabaseImages/ESC/large/ISS067/ISS067-E-34710.JPG
