SIGÉOM is a unique spatial reference geomining information system. It contains the entire Québec geoscientific database collected over the past 150 years. Every year, it grows richer with additional data coming from geological mapping surveys, prospection and exploration activities undertaken by the Ministry, mining companies and universities.

You will find :
An interactive map which gives a global overview of the SIGÉOM database.
Web map services that allow you to access the SIGÉOM database over the internet, and load import data directly into your GIS software.
The SIGÉOM à la carte gives access to the entire geoscientific database. This site allows searches to be performed by precise criteria and to get maps in different file formats.
EXAMINE constitutes the gateway to Géologie Québec record holdings with more than 80,000 documents (bibliographic data, reports, maps).

With SIGÉOM, you can visualise, consult and download the product of your choice.

The SIGÉOM database is a compilation of geologic information from governmental surveys, exploration works from the mining industry and university research literature. Geoscientific data essentially come from the fields of geology, geochemistry and geophysics.

Today's replacement value of SIGÉOM data is estimated at approximately four billion dollars. For works completed before 2004, cost evaluation is based on the estimation of investment costs for different types of surveys. For instance, the cost value of diamond drillings, which equals to more than 50% of the estimated database cost, has been set at 25$ per foot. Since 2004, the replacement value of SIGÉOM data represents actual expenses made by mineral exploration companies and the Québec government. These financial data are provided by mining credit management systems and government accounting services. The aforementioned replacement value represents a minimal estimation, since the analysis is not in constant dollars and some costs represent very conservative estimates.

Designing and implementation of SIGÉOM required a total investment of over $40 million since 1993. This number includes budgets allocated to data entry by the Ministry's personnel as well as maintenance and upgrading technologies.

SIGÉOM is a very important asset for Quebec's sustainable development. It makes mineral exploration more efficient by avoiding duplication of work and reducing the ecological footprint thereof. The resulting savings thus enable companies to invest their resources more wisely. SIGÉOM will continue to progress over time, as its value and usefulness are a true golden heritage!

The Step-by-step User Guide - Mastering the SIGÉOM Data helps users to choose between the different types of data source access available in order to compare and understand advantages and limits of technologies (formats) available. This guide is for all SIGÉOM users, from casual users searching for data about the general geology of Quebec to geomaticians interested in data access technologies.

The Interactive Map, which is freely available, allows a rapid visualization of numerous geological data in Quebec (geological units, mineral deposits, diamond drillings, etc.) which could be linked to mining data (mining activities, mines and projects, mining titles) and geographical data (satellite imagery, hydrography, topography, etc.).

The Interactive Map is unique and offers many features, including rapid display, zooming, transparency in data layer, as well as data selection and query. This easy-to-use tool makes geological, geographic and mining data available to all. The Interactive Map offers another significant feature: real-time access to the database, enabling users to benefit from continuously updated data. This is particularly important for certain users.

Access to Interactive Map

The so-called « Pseudo-Mercator » projection (also called "Web Mercator" or simply "Mercator"; EPSG code: 3857) is used in the SIGÉOM Interactive Map.

This projection utilizes a projected coordinate system used by many open source data providers (e.g. OpenStreetMap) and Web services (e.g. Google Maps). It is bounded by latitudes 85° N and 85° S so that when the world map is displayed, it appears in a square.

You may share your map as it appears on the screen with other users. Please refer to Section 2.11 of the Step-by-step User Guide - Mastering the SIGÉOM Data.

The Google geocoding API interface is used to acquire geographic coordinates from addresses, names of places or postal codes. In order to do this, the browser sends a request to the Google secured server(s) which returns the information. This works generally well with Google Chrome and Mozilla Firefox browsers, whereas it is problematic with Microsoft Internet Explorer (IE). The latter applies SOP (Same Origin Policy) rules which restrain calls between domains. To enable access to data, follow these simple steps:

1. In Internet Explorer, click Tools -> Internet Options
2. Click Safety, then select the Internet Zone
3. Set the Security Level to medium-high
4. Click Custom Level... to open the Security Settings section
5. Locate the Miscellaneous Section/Data Source Access on multiple domains
6. Click Activate

«A Web service is a rapid means to enable communication over the internet among various clients, providers and partners, regardless of languages and platforms used, a capacity known as interoperability. Web services comply with the specifications of the Open Geospatial Consortium (OGC) to make data accessible to all over the Internet.»

In digital cartography, Web services enable users to display maps and to process and save certain data as required. A Web map service (WMS) is therefore not an application in itself, but rather a data source used by different applications. It is integrated into a project through a «URL» address, which contains parameters related to the requested data, the coordinate system, the area of interest, etc. This method of dissemination is used to display maps from a Web site or from a geographic information system (GIS). A WMS server delivers the image requested from the GIS or the Web site through the Internet. The various data sets are then superimposed by the GIS or the Web site in order to produce the desired map. This approach provides the user with regularly updated data by official providers, with return periods dictated by respective mandates thereof. Today, several freely available and commercial softwares allow online connection to a data source using Web map services.

Web map services therefore facilitate a more effective dissemination of geospatial data from anywhere in the world, whether these are vector or descriptive data, metadata, raster images, map layouts, etc.

EXAMINE allows you to order and download digital data (FGDB, ShapeFile, Geotiff, Grid, Geosoft, XYZ, .BIN, .DAT, and .XLSX coordinate files, etc.) from geological reports produced by the Ministry. These data can be found under the Other digital data section.
Access to all documents

* Please note that only the perimeters covering assessment works are available in the Atlas géoscientifique vector data and SIGÉOM à la carte. The content of assessment work reports is only available through EXAMINE holdings.

The glossary containing the SIGÉOM database elements gives a description for each field in alphabetical order.

Documents are available here.

The Quebec Geomining Information System (SIGÉOM) uses numerous symbols and abbreviations to illustrate and describe the various geometric elements presented on:

• - the Interactive Map;
• - Web Mapping Services;
• - geological maps published in the Geological Bulletin and the Quaternary Bulletin.

Symboles and abbreviations used in SIGÉOM databases are grouped under different themes. Each theme provides users with an overview of the characteristics and rules used by Géologie Québec for the cartographic representation of the various geometric elements.

The information on this site is updated regularly as changes are made to the database and new feature layers are added to SIGÉOM. It replaces information previously published in the PRO 2000-08 and DV 2014-06 documents. This site also includes several elements of the General Geological Map Legend (Légende générale de la carte géologique; MB 96-28).

The document Geoscience Map Symbols and Abbreviations (Symboles et abréviations de la carte géoscientifique; DV 2014-06) provides an overview of the symbology used in SIGÉOM. It includes the geological map's colour grid legend, the list of lithologies, geological ages, minerals, structures and textures. It also provides simple explanations for applying the SIGÉOM symbology in the ArcGIS environment.

There are two layers of geological coverage in SIGÉOM: Regional Geology et General Geology.

The Regional Geology layer is the geological coverage resulting from the data collected during geological surveys carried out annually by Géologie Québec at a regional scale. At this scale, geological knowledge is not homogeneous throughout Quebec as many elements are still unknown to produce a unique and complete legend for the province. In this case, it is necessary to refer to the different legends of the geological maps that are based on geological surveys.

The General Geology layer is a homogeneous geological coverage of the entire province resulting from the synthesis and simplification of the regional geology layer. For this layer, there is a unique and complete lithological legend for Quebec. It accompanies the Geological Map of Quebec at scale 1:2 000 000 (Carte géologique du Québec; (DV 2012-06), which is available free of charge.
