ArcGIS Digitizing Tutorial

Introduction

  • Overview of tutorial on digitizing various map components using ArcGIS.
  • Focus on S3 based map.
  • Structure:
    • Adding a base map
    • Digitizing map components
    • Adding labels to digitized components

Part 1: Adding a Base Map

  • Open ArcMap.
  • Steps to add a base map:
    1. Go to File > Add Data > Add Base Map.
    2. Choose Imagery with Labels option and press Enter.
  • Use zoom functionality to view the area of interest.

Part 2: Digitizing

  • Preparation:

    • Create a folder to save generated shapefiles.
    • Connect to the folder via Catalog in ArcMap.
  • Steps to create a shapefile for lakes:

    1. Right-click on connected folder > New > Shapefile.
    2. Name shapefile "lakes".
    3. Select Polygon as feature type.
    4. Set spatial reference to WGS 1984.
    5. Confirm shapefile creation.
  • Digitizing the lakes:

    1. Ensure Editor Panel is active.
    2. Go to Editor > Start Editing.
    3. Choose Create Features > select lakes shapefile.
    4. Use Polygons construction tool to digitize lakes by clicking around the boundaries.
    5. Double-click to complete polygons.
    6. Change polygon color for representation (e.g., to blue).
  • Creating a shapefile for roads:

    1. Stop editing for lakes and save edits.
    2. Create a new shapefile named "roads".
    3. Select Polyline as feature type.
    4. Set spatial reference to WGS 1984.
    5. Start editing and select roads shapefile.
    6. Use Lines construction tool to digitize roads.
    7. Stop editing and save edits.
    8. Adjust symbology for roads (e.g., change color, increase width).

Part 3: Adding Labels

  • Open attributes table for roads.

  • Create a new column for road names:

    1. Exit editor mode.
    2. Select Add Field.
    3. Name the field "Road names" and set type to Text.
    4. Enter unique road names in the new column (e.g., "East-West Highway", "North-South Highway").
  • Add labels to roads:

    1. Stop editing and save edits.
    2. Go to Properties for roads layer > Labels tab.
    3. Enable label features and select the name column.
    4. Customize font options and apply.
  • Repeat the labeling process for lakes:

    1. Open attributes table for lakes.
    2. Add a new column called "Lake names" with type Text.
    3. Name the lakes (e.g., "Lake 1", "Lake 2").
    4. Stop editing and save edits.
    5. Enable labeling for lakes and customize font settings.
