Web Mapping Services (WMS)

The Maine Office of GIS and the Maine GeoLibrary Board provide web mapping services to distribute aerial photos and other digital data. A WMS is not a web application which you can see in a web browser; rather, it requires you to add the service to a GIS software application.


All of these services have KML or LYR shortcuts available in the MEGIS data catalog.

These services have been successfully tested in ArcGIS, MapInfo, Google Earth, QGIS, gvSIG, Gaia and uDig.

Tips for Using WMS

  • ArcGIS users - if the ortho service(s) display with incorrect coloring (i.e. all yellow or all red or all blue, etc.) this is due to the default ordering of raster bands in ArcGIS. The default order for both 3-band and 4-band rasters needs to be set to 1 - 2 - 3 for Red-Green-Blue. http://webhelp.esri.com/arcgisdesktop/9.3/index.cfm?TopicName=Setting_the_default_bands_to_display_multiband_rasters
  • WMS was not supported in ArcGIS until version 9.1. Users of 9.0 and 8.3 can access WMS with free add-ons from ESRI: 9.0 users can install service pack 3 to get WMS support; 8.3 users have to use the OGC Interoperability Add-On for ArcGIS, which is a free download
  • ALL SERVICES ARE WMS 1.1.1. There is a bug with using WMS in ArcGIS v 9.3.1 - you must explicitly set the version to 1.1.1 in the version drop-down box when making the connection.
  • CAD users - some CAD clients will attempt to connect at WMS v1.3, you can explicitly set the version for CAD clients by adding VERSION=1.1.1& to the end of the URL when making your connection.
  • MapInfo users - WMS help starts on page 454.
  • QGIS users - WMS help starts on page 63; specify image type PNG or the service will not look good.
  • uDig users - get the Add Data Wizard by clicking "Layers"; "Add".
  • Gaia users - WMS help starts on page 17.
  • Each service by default is provided in lat/long, but will also work in UTM and State Plane (and probably any other projection system).
  • Printing these and any other WMS using ArcGIS - if you are printing very large maps (E-size and larger), you may find the WMS is not printing properly. You can fix this by lowering the "image quality" in your printer settings to "normal" (1:3) or even lower. Even printing at the lowest setting ("fast" or 1:5), it will look fine on a big map.
