In a lay man's language, digitizing is the process of converting information to digital format, in this case maps. Digitizing converts raster data to vector data which can then be used for analysis this give various results. I am going to outline the process of georefrencing and digitizing using three common softwares which are ArcGis, QGIS, Grass and AutoCAD. In my future posts ibwiok also share Python scripts for these functions but it's not possible... By the time of writing this post... To digitize by just writing a Python script. Digitizing is a lengthy process is is very crucial for GIS and is better done manually. HOW TO GEOREFERENCE IN ARCGIS 1. Start by creating a folder on the desktop or your preferred storage place and place your map that needs to be georegerenced. 2. Start ArcMap and add the map by going to the plus sign at the toolbar, connect to folder and access the map. The map will load in Arcmap. 3. Go to the georeferencing tools at the tool bar and se

GIS (Geographic Information System) is a system that is designed and used to manage, capture, store, manipulate and present spatial data. GIS applications can be used to create interactive queries analyse geographic data and present it. GIS is dynamic, it can refer to different technologies, processes and methods. GIS has been used in engineering fields, planning, management, transport/logistics, insurance telecommunications among others. Any location based services can be done using GIS. Programming languages are always talking about variables. The main variable in GIS is location. Locations are extents on the earth's surface can be represented through latitudes and longitudes or through x,y,z coordinates. This can be referred to as raster and vector respectively. Every earth based location should be relatable to each other either relative or absolute relationship. With GIS you are able to analyse different geographic info at different levels. Various audiences require diff
