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

File Naming Rules

❌ Incorrect:

Giorgi Kapanadze.Group/1$ work1

❌ Do not use:

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

✅ Correct:

Giorgi_Kapanadze_Group_4_work_1

Tip

Use only Latin letters, numbers, and underscores (_) for:
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 digitizing task as part of this exercise.

  • Inside it, create the following subfolders:

  • Geodatabase
  • Style 
graph LR
  A[FirstName_LastName_GroupNumber_Assignment_Number] --> B{Project};
  A[FirstName_LastName_GroupNumber_Assignment_Number] --> C{lyr};
  A[FirstName_LastName_GroupNumber_Assignment_Number] --> D{shp};
  A[FirstName_LastName_GroupNumber_Assignment_Number] --> E{Geodatabase};
  A[FirstName_LastName_GroupNumber_Assignment_Number] --> F{Style};

Connect ArcGIS (from ArcCatalog) to this main folder.

  • Open "Digitalization_project.mxd" project from folder and save copy of it "Geodatabase_project". Also save another mxd file for old versions "Geodatabase_project10.0v".

  • Create a new File Geodatabase (.gdb extension) in the designated folder, also Style folder.

  • Create a feature dataset, import spatial data from the shapefiles located in the shp folder, and group them accordingly.

  • Correct layer Sources from shapefile to geodatabase feature class.

  • Open your existing project and replace the shapefiles with feature classes stored in the geodatabase.

  • Fill in additional information in the attribute table:

For roads:
- Create a column named "name" in which you will enter values like "E117" or "S3" for highways, or "300 Aragveli Street" for street names.
- Create a column named "length_m" where you will calculate the length of each feature in meters using the UTM zone.
- Create a column named "length_km" where you will calculate the length in kilometers using the UTM zone.

For rivers:
- Create a column named "name" where you will enter names such as "Mtiuletis Aragvi" or "Gudamakris Aragvi". If the river has no name, write "without name".
- Create a column named "length_m" to calculate the length in meters using the UTM zone.
- Create a column named "length_km" to calculate the length in kilometers using the UTM zone.

For bridges:
- Create a new column "type" where you will enter the category of the bridge: "Pedestrian", "Vehicle", or "Combined".

For parcels:
- Create owner columns named "name", "surname", "identity", and "personal_id" where you will enter the appropriate values.
- Create a column named "area_sqm" to calculate the length in meters using the UTM zone.
- Create a column named "area_sqkm" to calculate the length in kilometers using the UTM zone.
- Create a column named "periemter_m" to calculate the length in meters using the UTM zone.
- Create a column named "perimeter_km" to calculate the length in kilometers using the UTM zone.

For restaurants, hotels, and stadiums:
- Create a column named "name" where you will enter their respective names.

Additional info

Note: Not all feature types can be listed individually in these instructions.
Please process each layer according to its geometry type:

  • Point features:
    Add fields to store X and Y coordinates (in your projected coordinate system).

  • Line features:
    Add fields to calculate length:

  • "Length_m" — length in meters using the UTM zone.

  • "Length_km" — length in kilometers using the UTM zone.

  • Polygon features:
    Add fields to calculate area and perimeter:

  • "Area_sqm" — area in square meters using the UTM zone.
  • "Area_ha" — area in hectares.

  • "Perimeter_m" — perimeter in meters.

  • If any information is unavailable for a feature, leave the cell empty.*

  • Break down each dataset into categories based on names and attributes.

  • Assign appropriate labels to each object.

  • Save the style files for each dataset in the designated folder.

  • Compact Geodatabase

  • Click save project button again and close project

  • 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
