An overview of topology in ArcGIS

If you have features that are coincident and share the same location of coordinates, boundaries, or nodes, chances are that geodatabase topology can help you better manage your geographic data. Check link

Also you must see Topology rules poster

Assignment Instructions

⚠️ Work Environment

On university computers, work inside the folder:
C:\Users\Public\ or C:\Users\Public\Documents
(This is recommended even on personal computers, as the program may encounter issues when files are located elsewhere.)

📦 Required Software

  • ArcGIS – Required ✅
  • Google Earth – Optional (depending on the task) ✅

Warning

Do not delete completed work until the end of the semester.

Danger

❌ Do not use:

  • Georgian characters (ა, ბ, გ, დ, etc.)
  • Special symbols (other than an underscore _)

Archive names, folder and file names, and table column names.

📘 Step-by-Step Guide

Note

You must be authorized (logged in) on elearning.gtu.ge to download the data.

  • We are using a Geodatabase task as part of this exercise.
  • Rename main folder from geodatabase to topology. Example "Giorgi_Kapanadze_Group_4_work_5_topology"
  • Correct sources if it needed.
  • Also download shapefiles from here
  • Add inside project additional necessary folders:
    • Topology_rules
    • Archive
graph LR
  A[FirstName_LastName_GroupNumber_Assignment_Number] --> B{Archive};
  A[FirstName_LastName_GroupNumber_Assignment_Number] --> C{Project};
  A[FirstName_LastName_GroupNumber_Assignment_Number] --> D{lyr};
  A[FirstName_LastName_GroupNumber_Assignment_Number] --> E{shp};
  A[FirstName_LastName_GroupNumber_Assignment_Number] --> F{Geodatabase};
  A[FirstName_LastName_GroupNumber_Assignment_Number] --> G{Style};
  A[FirstName_LastName_GroupNumber_Assignment_Number] --> H{Topology_rules};
  • Create inside existing geodatabase new dataset, name it "topology".

  • Create Topology and some base rules as you need:

    • For polygon
    • Must not have gaps
    • Must not overlap
    • For line
    • line Must not self-overlap
    • Must not self-intersect
    • For point
    • point Must be properly inside
    • Must be covered by boundary of

  • In new dataset import spatial data(shp that downloaded before) for validation and correction.

  • Define topology rules and save them in a predefined folder.
  • Validate topology, add in project.
  • Correct errors and make exceptions as needed.
  • Properly saving the project file. Name it "Topology_project". Save another mxd file for old versions "Topology_project10.0v".
  • Compress (zip) your folder (named after your first and last name). 💾
  • Use formats like .rar or .zip.

  • Name the archive as:
    FirstName_LastName_GroupNumber_Assignment_Number

  • Send it to: giorgi.kapanadze@gtu.ge
