The <br />range of data formats supported is different for different software packages. For example, the GIS software <br />called Maplnfo can import data from the following formats: AutoCAD DXF/DWG, ESRI Shape file, MIF, <br />and Intergraph/MicroStation Design. <br /> <br />Part 8: How to create your own data: Digitizing and coding <br /> <br />The most common method of converting paper maps and other graphic data to a digital format is to use a <br />digitizing tablet. A digitizing tablet consists of a flat surface on which the map or graphic is placed. The user <br />traces the features of interest with either a pen-like stylus or a flat cursor, The tablet converts the position of <br />the stylus or cursor into a computer compatible signaL Before tracing the map, the user must identify points <br />on the map for which real world coordinates are known, Digitizing can also be performed on-screen. <br />On-screen digitizing is often performed over an aerial photograph or other image, For example, you can <br />digitize streets from an image and create a new Streets layer. <br /> <br />As data are digitized, each new line, point or polygon is usually automatically assigned a unique internal 10 <br />by the digitizing software, This distinguishes each discrete feature from another but provides no information <br />useful for a GIS, Additional information must be added by the user. For example, if you digitized the streets, <br />each street has to be assigned a street name. The procedure of adding information to the features in a data <br />layer is frequently called "coding". <br /> <br />8of9 <br /> <br />3/17/98 10:05 AM <br />
