Overview

GeoRepository is a powerful web application and tool for searching and displaying geodetic parameters contained within the IOGP EPSG geodetic parameter registry.

All parameters available in the database can be used in geodetic calculations with a high precision Geodetic Calculator.

Parameters can be accessed via the web site or through the Geodetic API.

EPSG Database

The GeoRepository database is based on the EPSG database recently modified to comply with many of the new features of the ISO 19111:2019 data model. This replaces the previous ISO 1911:2007 data model and extends the EPSG dataset.

The EPSG dataset is maintained by the IOGP Geomatics Committtee Geodesy Subcommittee. It provides and maintains the only definitive collection of geodetic parameters in existence.

The IOGP enforces strict policies on the inclusion and deprecation of records and maintains full metadata for each record, including a revision date, data source, description, versioning and deprecation.

Powerful Search Functions

Map search with satellite imagery

Coordinate reference systems and other geodetic objects are designed to be used within a specified area of the earth's surface. Map Search allows you to pan and zoom around a map of the world and select a specific location on which to base your filtered search. The search results will display only the coordinate reference systems, map projections and coordinate transformations which can be used at the specified location.

GeoLocation API

Map search also supports the GeoLocation API allowing searches for geodetic records that are relevant to your current location with a single click of a button. This feature works on most browsers and mobile devices equipped with GPS.

Name, code, alias and wildcard search

Various data sources often refer to geodetic parameters by abbreviation and alternate notation. GeoRepository includes a smart search algorithm that considers aliases, object names, abbreviations, EPSG codes and wildcards.

Tabbed Search Results

The geodetic parameter database contains a plethora of parameters, parameter values and metadata about various classification of geodetic objects that include Coordinate Reference Systems, Conversions, Transformations, Datums, Units of Measure, Extents and Coordinate Operation Methods to name a few. Results returned from the user defined queries are displayed in a series of tabbed pages that enable users to quickly and seamlessly navigate to an object whose details are required. Data mining functions provide users with additional methods of obtaining data about an object to level of their own choosing.

Exporting

GeoRepository offers a number of different export functions that enables the entire contents of the database or sub-sections of it to be exported to a variety of formats including, MS Access Database, Oracle SQL Scripts, MySQL Scripts, PostgresSQL scripts, GML and WKT.
