MAPOLOGY : GIS,Remote Sensing and Image Processing Tutorials

Any paper maps can be converted into the digitized data-driven interactive geospatial application by following the five steps as given below : 1) Scan the map into TIF 2) Import into DIVA-GIS 3) Create shapefiles for Placemarks, Pipelines or Roads or River and Some Area like Ponds, lakes, stadiums, etc. 4) Create Attribute Tables linked to the shapefiles 5) Export the tables and the shapefiles into an AppConverter to produce interactive Geospatial Application The entire procedure or the steps of digitization of maps by DIVA-GIS is explained in the presentation that can be accessed by clicking in the link . or view the video about the same presentation. If any terms like shapefile or attribute table are not clear or known to you then see this presentation .

Cover Feature: Shapefile is constructed to link a point in a digital map to a database storing related retrievable informations about the point. A vector data (points, lines, or polygons) storage format for storing the location, shape, and attributes of geographic features(ESRI Def). Shapefiles can be of three types : 1. Point Shape : A shapefile consisting of points which is used to represent datasets about a location(city,town etc.) 2. Polyline Shape : A shapefile of more than one point shape is known as Polyline shapefile and is used to represent information regarding line features like river,road,pipeline etc. 3. Polygon Shape : The polygon shapes are developed with the help of more than two points representing the vertices of a polygon.This type of shapes are used to exemplify a region like watershed,pond etc. Any shapefile can be zoomed in or out without any deformation in the spatial representation and thus such files are grouped under Vector images.
