Made using GIS data 'ETOPO1', QGis, this QGis tutorial, Inkscape, and the Wikipedia map conventions. Late Spring and Autumn Period, 5th centry BCE, before the breakup of Jin and the Qin move into Sichuan. QGis (full name: Quantum GIS) is a GPL license, cross-platform (Windows, Linux, Mac), and
The Geospatial Data Abstraction Library (GDAL) is a computer software library for reading and writing raster and vector geospatial data formats (e.g. shapefile), and is released under the permissive X/MIT style free software license by the Open Source Geospatial Foundation.
The subset tool can generate profiles for many other reasons as well. Listing the elements and attributes to include in the resultant profile schema and running the tool results in a single profile schema file containing only the user-specified items and all of the element, attribute and type declarations on which the specified items depend.
QGIS functions as geographic information system (GIS) software, allowing users to analyze and edit spatial information, in addition to composing and exporting graphical maps. [2] QGIS supports raster, vector, mesh, and point cloud layers. [4] Vector data is stored as either point, line, or polygon features.

Graphical view of the affine transformation. The registration of an image to a geographic space is essentially the transformation from an input coordinate system (the inherent coordinates of pixels in the images based on row and column number) to an output coordinate system, a spatial reference system of the user's choice, such as the geographic coordinate system or a particular Universal ...
Sample points (e.g., weather stations and sensor networks), Contour lines and triangulated irregular networks (TIN) are used to represent elevation or other values that change continuously over space. TINs record values at point locations, which are connected by lines to form an irregular mesh of triangles.
Besides these, there are other open source GIS tools: Generic Mapping Tools – A collection of command-line tools for manipulating geographic and Cartesian data sets and producing PostScript illustrations. FalconView – A mapping system created by the Georgia Tech Research Institute for Windows. A free, open source version is available.
