Load WMS Map

Requires database (c:\mapdata\wms_servers_v*.dbf)  with parameters of WMS servers which comes with MICRODEM.   If you want additional WMS servers,  edit this database.  The USE field has Y/N to indicate if you see the entries, which will be in alphabetical order.

USGS WMS map not be working.  You can instead try:

Imagery with the map scale approximately 2 m per pixel or larger.  This is leaf on.
Same request, but zoomed in.
Imagery with the map scale approximately 1 m per pixel or smaller.  This is leaf off.

Open any map, and select the region of interest.  You should not try this option on a map covering a huge area.  The map must have either a UTM or geographic projection.

Right clicking on the mapLoad, WMS maps, deliberate and pick layer you want.

WMS button on the Map toolbar--does the same as quick, and loads your favorite WMS source.  By default this is from USGS and provides about 1 m imagery.

7/7/2014: USGS changed their WMS parameters, and many of these options not completely working (use USGS ortho imagery).  If you want to use others, you will have to check the documentation, and change the settings in the database so that MICRODEM will create correct URLs to pass the WMS server.

  • USGS High Resolution Ortho (1 m) and USGS NAIP should have near seamless coverage of the entire US.
  • USGS High Resolution Ortho (1 ft) generally covers only urban areas.
  • USGS DRG can be problematic at times; use with care.
  • NASA Global Mosaic is likely not working.
