Quantum GIS

claimed by OSGeo - The Open Source Geospatial Foundation

Quantum GIS (QGIS) is a user friendly Open Source Geographic Information System (GIS) that runs on Linux, Unix, Mac OSX, and Windows. QGIS supports vector, raster, and database formats. QGIS is licensed under the GNU General Public License. QGIS lets you browse and create map data on your computer. ... [More] It supports many common spatial data formats (e.g. ESRI ShapeFile, geotiff). [Less]

GRASS GIS

claimed by OSGeo - The Open Source Geospatial Foundation

GRASS GIS, commonly referred to as GRASS (Geographic Resources Analysis Support System), is a free Geographic Information System (GIS) software used for geospatial data management and analysis, image processing, graphics/maps production, spatial modeling, and visualization. GRASS GIS is currently ... [More] used in academic and commercial settings around the world, as well as by many governmental agencies and environmental consulting companies. GRASS GIS is an official project of the Open Source Geospatial Foundation (OSGeo). [Less]

GAL Framework

Support library for development of GRASS GIS modules with aim on distributed computing and dynamic languages.

heightmap-dynamic-grass

The goal is to create effective algorithms of realtime visualization of dense-distributed vegetation, primary to be used in computer games with moderate system requirements. The existing version of algorithm was shown in action in a YouTube video (http://www.youtube.com/watch?v=VFhOI-SB18s).

序言前略，天国的河蟹们，草泥马现在是超越阿姆骡的存在 发展中的草泥马语在我们随机调查的100个网友中，有87.35%的网友认为草泥马语非常好！ 草泥马语第一个社区请求（Grass Community Request）：GCR001_W3C_DOM_Support_Draft ... [More] 于即日起开始草稿范本的起草工作，欢迎广大戈壁公民对该范本提出宝贵意见。 我们很高兴的接受了《中国人如何做爱》项目组提交的草泥马语的第一个issue: issue 1 关于草泥马语的CHTML支持问题。对此，草泥马语项目组作出了积极响应并得到了戈壁中央的大力支持，我们一定能够与CHTML项目组一起，为了建设现代化的马勒戈壁而奋斗。 热烈欢迎草泥马语的兄弟语言八卦语，虽然我们目前没有找到这个语言的官方网站，但是根据民法宪法刑法等有关法律，我们相信有官部门一定会解决这个困难，为了我朝网络的二胖化的进程奋斗！ 经过戈壁政府的不懈努力，值此2010年新春佳节之际，戈壁政府推出草泥马虚拟机贺岁版，草泥马语发展进程迈向新的台阶！ 再次非常高兴的接到dexter.yy童鞋提交的本项目的第二个issue，这为草泥马走向网络提供了技术支持，首先感谢dexter.yy同学对项目的支持和厚爱，再次感谢所有关心本项目的所有网友。 BriefThis is a programing language based on stack & heap. The only tokens used are '草','泥','马' and "河蟹", other chars are ignored as comments. 简介 《草泥马语》是一个基于堆和栈的编程语言，该语言的最大特点在于：所有操作全部由“草”“泥”“马”“河蟹”这4个命令完成，文件内的其他字符都作为注释而不参与程序执行。 有人抱怨说不会用，这不是就凑合了一个简易草泥马语学习指南（好像差不多完了） 另外，由于草泥马语言形式过于震撼，所以为了调试，编写了草泥马语逆编译器：gmhd（但是没有正向编译，囧，谁贡献一个？）可以吧草泥马语言代码反编译成比较好懂的伪代码。 第二个工具是whitespace程序转换器：ws2gmh,简单的replace而已。 ExampleThe code of grass-mud-horse language looks like following, this program loops from 1 to 10: 示例写出来大概就是这个样子，下面是一个从1到10的循环： 感谢(卡库尔 / Kakur)同学提供 草-草 草泥马数字1压栈Put a 1 on the stack 马-草草 草泥草草草草泥泥马在这里设置一个循环开始的标识Set a Label at this point 草-马草复制栈顶元素Duplicate the top stack item 泥马-草泥输出当前值Output the current value 草草 草泥草泥草马换行(10)压栈Put 10 (newline) on the stack... 泥马-草草输出...and output the newline 草草 草泥马1压栈Put a 1 on the stack 泥草-草草相加栈内两个元素Addition. This increments our current value. 草-马草复制栈顶以便比较Duplicate that value so we can test it 草-草 草泥草泥泥马11压栈Push 11 onto the stack 泥草-草泥相减，如果我们已经循环到11了应该会得到一个0到栈顶Subtraction. So if we've reached the end, we have a zero on the stack. 马-泥草 草泥草草草泥草泥马如果是0，跳到最后If we have a zero, jump to the end 马-草马 草泥草草草草泥泥马跳到开始Jump to the start 马-草草 草泥草草草泥草泥马设置一个标签标识循环结束Set the end label 草-马马清空堆栈，打扫卫生，整理整顿Discard our accumulator, to be tidy 河蟹正如其言Just as it says.

vtk-grass-bridge

vtkGRASSBrige provides a VTK/C++ interface to most of the grass gis raster and vector C library functions. Its using an intuitive class structure to hide the complexity of the grass libraries. Additionally, the vtkGRASSBridge provides access to grass C library functions for Python and Java, using ... [More] the VTK wrapper. Reader to convert grass datasets (raster, vector) into VTK datasets are provided for raster and vector data. All vtkImage- and vtkPolyDataAlgorithms can be used to process grass raster and vector data. vtkImages can be directly written as grass raster maps into a grass location. This library can be used to build comprehensive 3d visualisation of grass gis data with Java, Python and C++, as well as base for complex multithreaded image and vector filter to process grass gis datasets i.e: as backend for wps server.
