Using ResMap with Global Mapper 5.08 and above

Global Mapper has added links to over 9000 Landsat TM & ETM+ images in the release 5.08. Directly access this data in Global Mapper for free through the "Open ECW File from the Web" File menu option.

Global Mapper is more than just a viewer capable of displaying the most popular raster, elevation, and vector datasets. It converts, edits, prints, and allows you to utilize GIS functionality on your datasets in one low cost and easy to use software package.

Your data files can be loaded as layers, for example a Digital Elevation Model (DEM) can be loaded with a scanned topographical map to create a 3D sun shaded view of the map. A digital aerial image can be draped on the surface together with vector contour mapping to create a stunning and informative graphic. The results can be printed, or the workspace can be exported to a high resolution raster image for use in a presentation or report.

Have you ever received a dataset that does not match the projection of your current project? Simply load the dataset into Global Mapper, change the projection, and save the file to match your coordinate system. If the dataset is larger than the area you are interested in, export the data using the crop feature and change the projection and format of the data at the same time.

Global Mapper is more than just a utility; it has built in functionality for distance and area calculations, raster blending and contrast adjustment, elevation querying and line of sight calculations as well as advanced capabilities like image rectification, contour generation from surface data, view shed analysis from surface data, and triangulation and gridding of 3D point data. Repetitive tasks can be accomplished using the built in scripting language or the numerous batch conversion options.
