ISO Core 19115 Elements
Elements belonging to the ISO 19115 standard core.
- Dataset title: Name by which the afore-mentioned resource is known. This is created taking into account the topic of the data and its geographic location.
- Dataset reference date: Reference date for the afore-mentioned resource. This is considered to be the resource’s creation date (date of last day, when creation finished, in the event that this task has taken place during a period of time or that there have been successive updates), except for specific exceptions (such as aerial photographs, for which the flight date is used).
- Dataset responsible party:
Name, position information and contact data for the
person or organisation responsible for the resource. Two aspects are determined:
- Editor: the person or organisation that publishes the information.
- Producer: the person or organisation that creates the data or the last person to modify it.
- Geographic location of the dataset:
Two alternative options:
- Geographic position of the data set: This refers to 4 information fields, corresponding to the 4 boundary coordinates (north, south, east and west).
- Key words for the place (based on a thesaurus) to represent a geographic area
- Dataset language: Language or languages used in the dataset.
- Dataset character set: Complete name of the coding standard for characters used in the dataset.
- Dataset topic category: Main topics of the dataset.
- Spatial resolution of the dataset:
There are two possibilities:
- Dataset scale.
- Distance: length of one side of a pixel.
- Abstract describing the dataset: Brief summary of resource's contents.
- Distribution format: Two elements are requested: the name of the data transfer format and the version of this format (date, number, etc.).
- Additional extent information for the dataset
(vertical and temporal): Information is provided relating to one of these two questions:
- Date of the dataset content (period of time covered by the data contents: start date and end date).
- Vertical domain of the dataset.
- Spatial representation type:
Method used to represent the geographic information spatially. According to the chosen
option, one type of information or another is provided
(depending on whether it is a vector or a raster).
- Vector.
- Raster.
- Reference system: Information on the reference system, the datum, the ellipsoid and the projection.
- Lineage: This contains information on the
events or data or origin used in the data construction. It encompasses information on:
- Statement: General explanation concerning data producer's knowledge on the lineage of a dataset.
- Process steps: Information on the events or transformations in the dataset life including the processes used for maintenance. It provides descriptive information on the process, information on the date and time (ending date) when different processes take place, identification of the person or organisation associated with the process and the sources used.
- Sources used: Information on the data of origin used. Descriptive information is provided on the sources, the scale denominator, etc.
- On-line resource: Information on the on-line sources through which the dataset can be obtained. It mentions the URL where the data is located and a detailed description of what the on-line resource does.
- Metadata file identifier: Single identifier for each metadata file.
- Metadata standard name: Name of the metadata standard used (“ISO 19115 Geographic information – Metadata”).
- Metadata standard version: Metadata standard version used (for example "2003" if using the latest version of ISO 19115).
- Metadata language: Language used for metadata documenting.
- Metadata character set: Complete name of the coding standard for characters used for the metadata set.
- Metadata point of contact: Person or organisation that is the contact point for the metadata (they will be the metadata creators).
- Metadata date stamp: Date of creation of metadata. In the event that the metadata was produced over a period of time, the date will be the last day or the end day. Whenever the metadata is updated, this date is also brought up to date.
