The map features get sent to your computer as a GIS map.ĭigitizing using a digitizing tablet can be carried out in the following modes: After the setup phase, you trace the map features using a magnetic pen (puck).Then you digitize the bounding coordinates of the map.In your digitizing software, you then specify a coordinate system.You place your map on the digitize and then secure it with removable sticking tape.Digitizing tabletĪ digitizer is a special table with a grid of fine wiring behind the face. Which technique you choose will depend on the application, your budget, and the type and complexity of the data involved. There are five common GIS data input techniques. Follow this link to my 2+ hour FREE HD video QGIS tutorial series. Let me show you how to digitize in QGIS, how to shade a GIS map, how to geocode, & how to think like a GIS analyst. Here’s an overview five GIS data input techniques (ie. This involves converting CAD data to GIS data. It is mostly used for producing detailed cadastre maps. Entry of coordinates via coordinate geometryĬoordinate geometry involves manually entering X & Y coordinate information, and distances.This is where a scanner and its software captures the spatial data automatically. Its where you scan a map, georeferenced it to be in a coordinate system, and then trace the features using a mouse. Heads-up digitizing is mostly used for smaller GIS data collection projects. Then you trace over the map features with a puck. That’s a special table with a grid of fine wiring behind the face.
