Open Source GIS: A GRASS GIS Approach is designed to meet the needs of a professional audience composed of researchers and practitioners in industry and graduate level students in Computer Science and Geoscience.

The power of computing within Open Source environment is illustrated by examples of the GRASS usage with other Open Source software tools, such as GSTAT, R statistical language, and linking GRASS to MapServer. This book also contains a brief introduction to programming within GRASS encouraging the new GRASS development. Open Source GIS: A GRASS GIS Approach, provides basic information about the use of GRASS from setting up the spatial database, through working with raster, vector and site data, to image processing and hands-on applications. The project's website can be reached at and a number of mirror sites worldwide.
Using flag -o v.out.ascii output will be in old (version 4). Input coordinates may be given directly from standard input (stdin). The default mapset name is your login name, but any valid directory name can. The contents of an ASCII text file can be redirected to r.what as follows. We will start with a brief and focused introduction into GRASS GIS.

Following the Open Source model of GRASS, the book includes links to sites where the GRASS system and on-line reference manuals can be downloaded and additional applications can be viewed. v.out.ascii converts a GRASS vector map in binary format to a GRASS vector map in ASCII format. The primary GIS applications that GRASS has been developed for are resource. The standard least-squares method tries to minimize i r i 2, but when outliers. A single LAS file can only contain data for one well, but it can contain any number datasets (called 'curves') from that well. Well logging is used to investigate and characterize the subsurface stratigraphy in a well. Open Source GIS: A GRASS GIS Approach was written for experienced GIS users, who want to learn GRASS, as well as for the Open Source software users who are GIS newcomers. A vector map in GRASS native vector format may contain a mix of primitives including points, lines, boundaries, centroids, areas, faces, and kernels. Log ASCII standard (LAS) is a standard file format common in the oil-and-gas and water well industries to store well log information.
