Example GIS Data Submission for City Administrators
Santiago, Chile - Reference Implementation
This document explains the example submission created from Santiago, Chile's GIS data, demonstrating the standardized format all cities should follow, including boundary, neighborhood, and Point of Interest (POI) data.
Files Created
1. Example Directory: Example_City_Submission/
Contains the properly formatted files that demonstrate the standard structure.
2. Example ZIP File: Santiago_Chile_Boundaries_EXAMPLE.zip
Ready-to-submit ZIP file showing the exact format expected by the system.
3. Documentation: README_FOR_CITY_ADMINISTRATORS.txt
Comprehensive guide included in the example folder for city administrators.
Why Santiago, Chile Was Chosen
Santiago was selected as the example because it demonstrates best practices:
- ✅ Clean Organization: Files directly in GIS SHP folder (no confusing nested directories)
- ✅ Complete Data: Boundary, neighborhood, and POI files provided
- ✅ Proper Components: All required shapefile components (.shp, .shx, .dbf, .prj, .cpg)
- ✅ Reasonable Size: Manageable file sizes (boundary: 42KB, neighborhoods: 18KB, POI: 85KB)
- ✅ Mixed Geometry: Polygon boundaries + Point POI locations
- ✅ Good Naming: Clear, descriptive file names with category suffixes

How to Use This Example
For City Administrators:
- Download the
Santiago_Chile_Boundaries_EXAMPLE.zip
file
- Extract and examine the file structure
- Read the
README_FOR_CITY_ADMINISTRATORS.txt
carefully
- Follow the same naming pattern for your city:
- Replace "Santiago_Chile" with "[YourCity]_[YourCountry]"
- Keep the same file extensions and structure
- Create your own ZIP file following this exact format
For Project Managers:
- Share the ZIP file with all participating cities
- Reference this structure in training materials
- Use as validation template for incoming submissions
- Point cities to this example when they have questions
Required Data Categories for Submission
Complete Data Package Requirements
Cities should provide data for these 5 essential categories to ensure comprehensive spatial analysis:

Description: Official city administrative boundaries that define the city limits and jurisdictional areas.
Geometry: Polygon | Priority: REQUIRED
2. Subdivision Boundaries
File: [CityName]_[Country]_Subdivisions.shp
Description: Zones, districts, neighborhoods (if available) for detailed spatial analysis.
Geometry: Polygon | Priority: RECOMMENDED
3. Public Open Spaces
File: [CityName]_[Country]_Public_Spaces.shp
Description: Parks, green spaces, and recreational areas accessible to the public.
Geometry: Polygon or Point | Priority: RECOMMENDED
4. Cultural Sites
File: [CityName]_[Country]_Cultural_Sites.shp
Description: Museums, heritage sites, and cultural landmarks within the city.
Geometry: Point (preferred) or Polygon | Priority: OPTIONAL
5. Recreational Facilities
