CIETmap is written in Python and uses PyGTK for its graphical interface. The raster and vector mapping is handled by a custom library built on top of the GTK+, GDAL and GtkGLExt libraries. NumPy provides analytical and calculation support and RPy is the Python access to R. The CIET group is currently testing CIETmap to make it available to ...
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.
Whitebox GAT running on MacOS displaying raster and vector data. Whitebox GAT map layout management. A complete map in Whitebox GAT. Whitebox Geospatial Analysis Tools (GAT) is an open-source and cross-platform Geographic information system (GIS) and remote sensing software package that is distributed under the GNU General Public License.
The result may be written to a fourth bitmap, though often it replaces the destination. The pixels of each are combined using a program-selectable raster operation, a bit-wise boolean formula. The most obvious raster operation overwrites the destination with the source. Others may involve AND, OR, XOR, and NOT operations. [1]
ArcCatalog is the data management application, used to browse datasets and files on one's computer, database, or other sources. In addition to showing what data is available, ArcCatalog also allows users to preview the data on a map. ArcCatalog also provides the ability to view and manage metadata for spatial datasets. [82]
Bresenham's line algorithm is a line drawing algorithm that determines the points of an n-dimensional raster that should be selected in order to form a close approximation to a straight line between two points.
Union-find essentially stores labels which correspond to the same blob in a disjoint-set data structure, making it easy to remember the equivalence of two labels by the use of an interface method E.g.: findSet(l). findSet(l) returns the minimum label value that is equivalent to the function argument 'l'.
CARTO (formerly CartoDB) is a software as a service (SaaS) spatial analysis platform that provides GIS, web mapping, data visualization, spatial analytics, and spatial data science features. The company is positioned as a Location Intelligence platform due to its tools for geospatial data analysis and visualization that do not require advanced ...
