Arcgis10.1: Digitization of Spatial Entities

Aim:
To create Point, Line and Polygon entity features for the given topographic sheet, using ArcGis Editing tools

Procedure:

Step 1: Map Input
Identify the Point, Line and Polygon Entities and the location datasets. For this session, Cities were located for Point, Rivers were located for rivers and Perennial water bodies were located as polygon  entities on the given topographic sheet. 


Step 2: Map Processing
·         Create a New polygon Shapefile in ArcCatalog (target Folder) and Add Field for ‘Name” in the Attribute Table of polygon Shapefile layer.
·         Start “Editor” and symbolize the line entities using “Create Features” Point, Line and polygon Construction tools.
·         Save and Stop “Editor”
·         Label the Point, Line and Polygon  entities with the “Name” of the Cities, Rivers and water bodies. In this case, Names were not accurately identified; hence Dam Capacity was selected for labeling.
·         Layout map with elements of Title, Sub-Title, Scale, Arrow,  Legend and credits

Step 3: Map Display
Export map to Jpeg format

Conclusion:

The Spatial entity features for the given topographic sheet are processed and displayed using ArcGis.
