Abstract: 

The map shows the amount of area equipped for irrigation around the turn of the 20th century as a percentage of the total area on a raster with a resolution of 5 minutes. The area actually irrigated was smaller, but is unknown for most countries. A special note has to be made for Australia and India where the map shows the total area actually irrigated. This is due to the fact that statistics collected in Australia and India refer to actually irrigated area as opposed to statistics with area equipped for irrigation which are collected in most other countries. An explanation of the different terminology to indicate areas under irrigation is given in this glossary http://www.fao.org/nr/water/aquastat/irrigationmap/index20.stm.

The digital global map of irrigated areas is a raster map with a resolution of 0.5º by 0.5º (raster call area approx. 3000km2 at the equator, and 2100 km2 around 45º latitude). For the whole land area of the globe (except Antaractica), the data set provides the irrigation density in 1995. For many countries, no data on the total irrigated area exactly in the year 1995 are available, but for years between 1990 and 1995, and no correction was applied to these data The definition of controlled irrigation as used by FAO is followed (FAO, 1995). Flood recession cropping areas and cultivated wetlands are not included in the map.

A digital interactive map, a static global map, downloadable spatial data, and full metadata for each region are available on the website.

Includes various PDF files with maps, documentation and reports.

Since 1999 the methodology to produce the map has been improved which made it possible to increase the spatial resolution of the map to 5 minutes (about 10 km at the equator). The objective of the cooperation between the Universities and FAO is to develop global GIS coverage of areas equipped for irrigation and to make it available to users in the international community. The data collected through the AQUASTAT surveys will be used to improve the overall quality and resolution of the information.

A digital interactive map, a static global map, downloadable spatial data, and full metadata for each region are available on the website.

Format: 
Web-browser based interactive map
Who can use this data: 
Public
Abstract: 

Agro-Maps is volume #32 in the FAO Land and Water Digital Media Series.

This CD-ROM product contains statistics on crop production, area harvested and crop yields, aggregated by subnational administrative districts, for more than 130 countries, in seven geographic regions (Africa, Asia, Near East in Asia, Latin America and the Caribbean, North America and Oceania).

The statistics are linked to unique identifier codes of the administrative districts in each country. This allows users to view readily, and subsequently analyse, the statistics for a single country or for an entire region as maps.

The data can be viewed through a web-browser based information portal that is accessed via the startup application on the CD. Supplementary data in the form of coverages are included in a .zip file to allow for export to other GIS software. Metadata for this product is not readily available.

There are also downloable adata tables available from the URL above.

The LIO Make-a-Map application allows you to make your own topographic map of any part of Ontario. The data used to make these maps is largely from the Ministry of Natural Resources and Natural Resources Canada, and is suitable for display at scales from 1:10,000 to 1:250:000.

  The application will allow you to create PDF-format maps, print them on a local printer or send them via email, and create "bookmarks" which will allow you to store map locations and return to them later.

 

A variety of vector layers and topographic imagery is available for display under the following categories:

  • Administrative boundaries
  • Natural features
  • Constructed features
  • Grids

Air Quality: Pollutant and Smog Day Data

Author: 

Ontario Ministry of the Environment

Year: 
Various, from 2000
Format: 
.csv, .xls
Who can use this data: 
Public
Abstract: 

The Ontario Ministry of the Environment (MOE) has created the user-friendly website Air Quality Ontario in order to provide Ontarians with current Air Quality Index (AQI) readings, historical ambient air pollution data air quality forecasts and current pollutant concentrations, as well as information on actions that can be taken when a smog alert is issued. 

Reports and forecasts of air quality (based on the AQI) can be browsed by city on the website, but downloadable datasets are also available.  Users can download historical data in the form of hourly readings of various pollutants (Ground-level Ozone, Nitrous Oxides etc.).  The datasets are provided by monitoring station location (e.g. "Hamilton West") in .csv format, which can be imported into Excel or ArcMap.  Also available from the website are "Smog Advisory Statistics", which give gives the dates on which "Smog Days" were declared and the areas in which they applied.  These datasets are provided in .xls format, which can be converted to .csv format in Excel to be imported to ArcMap.

Please note that therer is no geospatial data directly included in these datasets.  If users are interested in performing geospatial analysis in ArcMap, the locations of the monitoring stations or affected areas must be manually added by the user.  The website does provide the Lat-Long coordinates of each monitoring station when you download the hourly pollutant data for that station.

Hydrometric Database

Year:

Who can use this data: 
Public
Abstract: 

The Water Survey of Canada is a branch of Environment Canada which provides comprehensive flow or surface water level data for rivers across Canada.  For each hydrometric station, one can query daily or monthly flow or water level rates for the years that the station was active.  Some stations only have records for a few years, while others have records for over 80 consecutive years.  Some stations also have records for sediment loads and concentrations.

The data are not provided in any geospatial format, but there is an interactive Google Map interface which shows the location of currently active stations.  The metadata document also contains the latitude-longitude coordinates for each station.  The data can be viewed in an graphical format, which can calculate basic statistics about the data range (e.g. calculate the mean flow rate of a river over the course of a whole year).  The data can be viewed tabular format in the web browser, and can also be exported in .csv format, which can be exported into Microsoft Excel.

Abstract: 

The National Hydro Network (NHN), for which the standard was officially adopted by the Canadian Council on Geomatics (CCOG) in August 2004, focuses on providing a quality geometric description and a set of basic attributes describing Canada's inland surface waters. It provides geospatial vector data describing hydrographic features such as lakes, reservoirs, rivers, streams, canals, islands, obstacles (e.g. waterfalls, rapids, rocks in water) and constructions (e.g. dams, wharves, dikes), as well as a linear drainage network and the toponymic information (geographical names) associated to hydrography.

The NHN forms the hydrographic layer of the GeoBase. The best available federal and provincial/territorial data are used for its production, which is done jointly by the federal government and interested provincial and territorial partners.

The modeling work of the NHN is based in part on Linear referencing System (LRS) concepts. This approach allows the management of geometric representations separately from attribute information (referred to as events in LRS). Unique identifiers (called National Identifiers - NID), associated to each NHN feature, allow for efficient management of updates. The NHN is a vector, topographic data product primarily designed to allow hydrographic network analysis. It is intented for water flow analysis, water and watershed management, environmental and hydrographical applications, as well as for a multitude of cartographic applications.
