| # Digitised maps in Trove | ||
|
|
||
| [](https://repository.frictionlessdata.io/pages/dashboard.html?user=frictionlessdata&repo=repository-demo&flow=frictionless) | ||
|
|
||
| This repository contains metadata describing digitised maps in Trove. The methods used in creating the datasets are described in the [Trove Maps](https://glam-workbench.net/trove-maps/) section of the GLAM Workbench. | ||
|
|
||
| Files include: | ||
|
|
||
| * `single_maps_20230131.csv` – metadata harvested from Trove | ||
| * `single_maps_20230131_coordinates.csv` – coordinate strings in the metadata (points and bounding boxes) parsed and converted to decimal values | ||
|
|
||
| ## `single_maps_20230131.csv` | ||
|
|
||
| Contains the following columns: | ||
|
|
||
| * `title` – title of the map | ||
| * `url` – url to the map in the digitised file viewer | ||
| * `work_url` – url to the work in the Trove map category | ||
| * `identifier` – NLA identifier | ||
| * `date` – date published or created | ||
| * `creators` – creators of the map | ||
| * `publication` – publication place, publisher, and publication date (if available) | ||
| * `extent` – physical description of map | ||
| * `copyright_status` – copyright status based on available metadata (scraped from web page) | ||
| * `scale` – map scale | ||
| * `coordinates` – map coordinates, either a point or a bounding box (format is 'W--E/N--S', eg: 'E 130⁰50'--E 131⁰00'/S 12⁰30'--S 12⁰40') | ||
| * `filesize_string` – filesize string in MB | ||
| * `filesize` – size of TIFF file in bytes | ||
| * `width` – width of TIFF in pixels | ||
| * `height` – height of TIFF in pixels | ||
|
|
||
| ## `single_maps_20230131_coordinates.csv` | ||
|
|
||
| Contains the following metadata: | ||
|
|
||
| * `title` – title of the map | ||
| * `url` – url to the map in the digitised file viewer | ||
| * `coordinates` – map coordinates, either a point or a bounding box (format is 'W--E/N--S', eg: 'E 130⁰50'--E 131⁰00'/S 12⁰30'--S 12⁰40') | ||
|
|
||
| Points or centres derived from bounding box: | ||
|
|
||
| * `latitude` | ||
| * `longitude` | ||
|
|
||
| Bounds of box: | ||
|
|
||
| * `north` | ||
| * `south` | ||
| * `east` | ||
| * `west` | ||

| # trove-maps-data | ||
|
|
||
| This dataset contains metadata describing digitised maps in Trove, harvested from the Trove API and other sources. | ||
|
|
||
| These datasets were generated using notebooks in the [trove-maps](https://github.com/GLAM-Workbench/trove-maps/) repository. | ||
|
|
||
| For more information and documentation see the [Trove digitised maps metadata](https://glam-workbench.net/trove-maps/single-maps-data/) section of the [GLAM Workbench](https://glam-workbench.net). | ||
