What is Envision?
Envision is intended to assist anyone with an interest in environmental data to
access geographical data produced by the EPA. Much of the data you can view and
query on Envision is also available to download either directly from Envision or
from the Data Download
option of the EPA GeoPortal.
Envision was developed for the EPA. Queries about Envision (or EPA GIS data in general)
should be submitted using
the Contact Us link to make sure they are dealt with promptly.
Envision Technical Details
Envision was developed using mainly JavaScript and HTML, however, some of the server components are .NET WCF. We have used
- ESRI JavaScript API,
- JQuery,
- Dojo,
- OpenLayers
JavaScript Libraries on the client side; and following products on the server side
- RESTFul web services with WCF
- ESRI ArcGIS Server,
- MS SQL Server 2008 and Reporting Services,
- GeoServer as WFS (OGC Web Feature Service) Server for Downloads,
- GeoNetwork as CS/W (OGC Cataloue Service For the Web) Metadata Catalogue Server for ISO 19115 and INSPIRE Metadata.
We have tested the Envision and believe that it is fully compatible with the following browsers:
- Internet Explorer 7+,
- Firefox 3.5+,
- Chrome,
- Opera,
- Safari 3+.
Envision can be used with older versions of Internet Explorer (IE 7 and IE 8) but there are some small limitations in the display when these versions are used.

Data sources
The EPA ENVision mapping viewer has been provided to enable visitors visualise environmental
data and is intended as a tool for the personal investigation of environmental issues.
Data portrayed on the viewer has been provided by a number of sources
- Environmental Protection Agency
- Geological Survey of Ireland
- Teagasc
- National Parks and Wildlife Service
The EPA does not guarantee the accuracy of data presented on this viewer and is
not responsible for incorrect interpretation. If accuracy is important, it is recommended
that you obtain a copy of the original maps on which the information is based and
verify its accuracy.
National Soils Database
The soils classification data associated with spatial points on the map cannot be
used at a local scale, as this information is derived form a scale of 1:575,000
generalised soil map of Ireland and therefore should be used with caution when describing
point or small scale data.
When using the NSDB datasets & maps you are required to cite the original source
of these resources. This citation must include the names of the original authors
of the project or resources. To see a proposed citation from the EPA ERC Safer website
