PROJECT 1 : DIGITIZATION OF RAW MAP

Digitization is the process of converting geographic data into digital form. During this process, spatial data on maps or images are traced as points, polylines or polygons. It has many uses in GIS, including recording and displaying geographic information, generating map layers, and storing data.

 

• For my digitization project, map layer from Google satellite was added and my faculty which is the  Faculty of Environment was identified in the map.

• The faculty area was then mapped and shaded by using polygon function then the faculty area was mapped by plotting lines that resembles road and points that resembles stops.

• The mapped faculty area was saved and was prepared to transformed into proper map projection

• The map was created by adding legends, scale, north arrow, coordinates and tittle. The grids and coordinates for this map was set to follow KERTAU RSO MALAYA (METERS) according to proper projected coordinate system.

Digitizing is important because it lets use do inquiries on the geometry of the produced vector data. For example, we can query the area of a polygon or length of a polyline. We can also do statistical operations on these queries, like determining the mean area of all the polygons belonging to one ground type class.
