Accessing Data

Geographic Information System [GIS] Format (requires GIS software):

GoogleEarth format (KML files)

Paper Maps

WARNING – MDIFW’s wildlife/habitat data is updated periodically. We recommend using WMS/WFS to link “live” to the most current versions. Alternatively, those using downloaded shapefiles, local copies of data, KML files, CDs, and paper maps can receive automatic notification of data updates by sending an email address to Donald.Katnik@maine.gov.

MDIFW’s Wildlife/Habitat Data Webservices

Webservices allow users outside the state network to connect to MDIFW’s GIS data layers in the Maine Office of GIS data catalog. This is the preferred method for accessing MDIFW’s data because it ensures that data is the most current. Users can connect via either WMS or WFS. You must have GIS software that supports WMS/WFS (ESRI’s ArcGIS does).

The Web Mapping Service [WMS] is best for simple viewing of data. It is easier and faster than WFS and comes pre-symbolized using DEP’s Environmental Vulnerability Index symbology), but supports only limited querying of data features (using the Identify “i” tool). You cannot do advanced spatial or attribute queries or selections. The WMS was designed to support DEP oil spill responders needing to check for new data since the last set of EVI maps were printed. Click here for instructions on connecting to and using the WMS (PDF).

The Web Feature Service [WFS] is better for working with individual features and supports advanced spatial/attribute queries. For ArcGIS, this requires the Data Interoperability connection! A copy of the data can be saved locally so that geometries can be analyzed and manipulated. Warning – users assume all responsibility for manually refreshing local copies of data downloaded from the WFS and any changes made to local copies of the data. Users also are prohibited from redistributing MDIFW’s data (maps generated using the data are allowed if the map includes the date the data was obtained from the WFS). Click here for instructions on connecting to and using the WFS (PDF).

CD Request

To request a digital copy of MDIFW’s wildlife/habitat data, send an email to Donald.Katnik@maine.gov.

Please write “Data Request – Your Name” in the email subject line to help us track and save the request.

In the body of the email message, please indicate:

  1. Data sets of interest (list individual data sets or just indicate “all”):
  2. Geographical area of interest. Include either a list of townships or attach a GIS shapefile.
  3. Your contact information including address, phone number, and email.

Data will be shipped as ESRI GIS shapefiles, UTM NAD83 Zone 19N. Each data set will have attached metadata. You must have GIS software to use this data!

If the requested data is small enough to email, it will be emailed to you. Otherwise a CD will be sent via regular mail.

We will make every attempt to process data requests as quickly as possible, but due to state budget shortfalls and other priorities may require several weeks. If you need data faster, please consider using our automated data webservice, the MEGIS data catalog, or GoogleEarth.

GoogleEarth

MDIFW recognizes that many potential data users do not have access to GIS software and that GoogleEarth is a popular alternative. MDIFW therefore provides copies of its wildlife/habitat data sets in GoogleEarth (KML) format, but users assume all responsibility for using GoogleEarth in accordance with its license restrictions. Please go to GoogleEarth’s website to learn about their software and licensing rules.

Note that MDIFW has limited control over how these KML files will display in GoogleEarth and cannot insert appropriate language concerning the meaning of the data into any maps printed using GoogleEarth.
