Free topographic software for windows

UglyBass Utilities 1.0 offers users a Windows Mapping Software that allows sportsman to view topographic or other User maps and geocode them to specific Latitude and Longitude.

Major Features:

1. Allows Marking Landmarks and locations with Symbols and storing information on each point.
2. Full drawing over the map, as well as distance Measuring, and even a handy Fish Weight calculator are included.

With Wissenbach Map3D you will be able to create, view and edit GPX (GPs eXchange) files. A GPX file contains trails, routes, and waypoints.
All of the objects produced by a non-mapping GPS unit such as the Garmin eTrex summit. A GPX file can be created by reading data from your GPS receiver with this program, or by drawing on this program over a background topographic map. This program will also write GPX tracks, waypoints, or routes to your Garmin receiver, to allow you to follow trails which others have previously logged with their GPS receivers.
The background maps for the program are the familiar USGS 7 1/2 minute topographic maps, converted by the United States Government with your tax money to Digital Raster Graphics (DRG) files. This program does not directly open DRG files but instead uses the DRG files as a background resource.
When you define a region of interest by opening a GPX file, by downloading data from the GPS receiver, or by using View->Enter Coordinates to manually specify a location, the program attempts to draw a background topographic map by looking on your computer for USGS DRG files. Any GPS data, either read from a GPX file or from your GPS receiver, is then overlayed on top of the background maps.
WM3D auto-downloads and displays topographic maps and aerial photos from TerraServer USA. Another program which operates in this manner is Expert GPS. (Expert GPS was the first program to automatically download Terraserver tiles in this manner, as far as I know.)
Wissenbach Map3D initially opens with a blank screen, because the geographic extent desired is unknown. To start, either connect a Garmin Receiver to the serial port and use GPS, Read From GPS, or View, Enter Coordinates. A good way to find starting coordinates for planning a hike or bike or ski trip is to use the USGS Geographic Names Information System search form United States and Territories.
If you are interested in terrain visualization but this program doesnt meet your expectations, see Terrain Visualization for programs with similar capabilities.
If you have an older (than eTrex) model Garmin or use a Magellan or Brunton or Lowrance GPSR and need topographic mapping capability, or you have trouble with this program or just want to try something different I can recommend the moderately priced Expert GPS from Topografix. which can read and write the GPX files produced by this program. (I received a free copy of ExpertGPS from Topografix for collaborating with the design of the GPX file format).

WW2D 0.99.87 allows you to explore Earth using satellite imagery, topographic maps and images from other data sources also providing large placenames and boundaries database and allowing you to install community-made add-ons for even more information about this planet. Moon and Mars support World Heritage add-on Rapid Fire MODIS add-on Demis WorldMap and VectorOverlay add-on WW2D is cross-platform, free and open-source application similar to NASA World Wind or Google Earth software.
