About the Georepository - Geodetic Parameter Repository
GeoRepository Web Application |
||
|
GeoRepository is a powerful web application and API for searching, displaying and retrieving geodetic metadata such as Coordinate Reference Systems and Coordinate Transformations with their EPSG codes, Conversion parameters, Extents and Remarks, as well as a complete audit trail on its history. It comprises the website GUI, the EPSG geodetic database, and application server as shown in the figure below. |
 |
|
 |
Access to all parameters in the GeoRepository is available through RESTful geodetic API application server, which provides access to all parameters within the registry and includes advanced search methods, textual and graphical. It can be consumed by any programming language supporting the RESTful protocol. For more information about the web service please contact our team here. |

Wildcard search
Wildcards and filters in text searches
Text searches search the Name and Alias fields, and also the Extent Description field.
Strings which are entirely numeric will additionally search the object Code field.
Users who are logged in may extend the search to also include the Remarks field.
Text searches are case-insensitive.
Wildcards
| Wildcard | Example |
| % or *
|
Any wildcard characters |
| ? or _ | One wildcard character |
| [ - ] | [ - ] Range e.g. N[a-c] will return all geodetic objects that contains a string starting with the letter 'N' or 'n' followed by any of the letters contained within the range specified within the square bracket, e.g. letters a, b and c. |
| | | Or e.g. E[a|e]M will return all geodetic objects that contains a string starting with the letter E(e), ends with the letter M(m) and also contain either the letter a or letter e. |
The text string is automatically prefixed and suffixed by the % wildcard. These prefixes and suffixes are not applied to searches for object code.
Filters
[name] =xxx There is no limit to the length of the text string that can be submitted to the search
[code] =yyy [code]< yyy [code] > yyy, where yyy is an integer and does not accept wildcards
[type] =xxx applies a filter by subtype. It may be used to filter subtypes of CRS, CS, or datum.
Wildcards and filters may be combined together.
