GRASS GIS

GRASS GIS is generally called GRASS (Geographical Information Analysis Support System) and is a free open source for geospatial data management and analysis, image processing, graphic and map creation, spatial modeling, and geographic information system It is a geographic information system (GIS) software suite. Visualization GRASS GIS is currently used in academic and business environments around the world, as well as many government agencies and environmental consulting firms. This is a founding member of the Open Source Geospatial Foundation (OSGeo).

By the late 1970's, two public domain GIS systems (MOSS and GRASS GIS) were developed, and in the early 1980's M & S computer (later Intergraph) was used for research on CAD platform and environmental system. ESRI (CARI), CARIS (Computer Assisted Resource Information System), MapInfo and ERDAS (Global Resources Data Analysis System) became commercial suppliers of GIS software and successfully combine many CGIS functions to create space and attributes as the first generation It joined by the method of. Information for organizing attribute data into database structure and second generation generation method

In 1968, Roger Tomlinson first used the term GIS in his paper "Geographic Information System for Regional Planning." Tomlinson is widely recognized as "father of GIS". GIS has opened up a new chapter of map creation. It allows us to link the database to the map, which enables many services to support location. In addition to adding pins, we display data on the map and generate maps using that data. Indeed, there are many public city data that anyone can use to create a map. Lance Martin shared about how he used the Open City data to map SF and NYC. He uses data such as homelessness, theft, mouse check, noise complaints. This is a very interesting way for me to know my city. In addition, his rat activity map is a very useful material and I can reduce the opportunity to see the mouse.
