In GIS, the data is divided into two types, one is the raster data , such as some satellite remote sensing images, scanned images topographic map and aerial drones and the like; another data type is vector data , the use of point, line and surface abstract representation of the real world. Raster data is readily available and direct analysis, and vector data generally require processing, in particular, is a subsidiary of attribute information, today we have to share with you how to be vectorized map data, the end of the text attached video tutorials .
First open ArcMAP, in the toolbar, select the + icon to add a base map.
And then select a folder in the directory, right-click the new → shapefile, were established point, line, surface document coordinate system selection WGS1984 Transverse Mercator coordinates, other coordinate systems may be selected according to their needs.
Click Editor → to start editing, for example, we want to build a number of POI points of interest, click on the Edit window editor → → Create elements, then we can see the Create Features window.
In the Create Features window click on the point, which you can use the mouse POI points plotted on the base map.
If you want to draw a line about the vector, such as railways, roads, etc., to create a feature selection panel line, then draw, double-click to complete.
If you want to lakes and other surface vector drawing, just create a feature selection panel surface, then draw.
We can also use the time to share visualization to the point of creation, line, surface layers for visual editing.
