📖 What's Inside: Quick Guide to All 17 Tools (Click to expand)
🔗 Common Workflows - Tabs That Work Together:
Red Cross Code Lookup
Built-in database of all Red Cross chapters, regions, divisions, and counties. Search by name to find ECODE, RCODE, DCODE, and FIPS codes instantly.
Why Use Codes Instead of Names?
Codes are standardized, unique identifiers that eliminate ambiguity and spelling errors.
ZIP Codes (5-digit)
What: United States Postal Service ZIP Code Tabulation Areas (ZCTA5)
Format: 5
digits (e.g., 33019, 02134)
Why better:
Every ZIP code is unique. "Miami" could refer to the city, county, or
multiple ZIP codes. 33101 is unambiguous.
FIPS Codes (5-digit)
What: Federal Information Processing Standards codes for counties
Format: 5
digits = State FIPS (2) + County FIPS (3), e.g., 12011 =
Florida (12) + Broward County (011)
Why better:
"Dallas" could be Dallas County, TX (48113) or Dallas County,
AL (01047). FIPS codes are unique nationwide and never change.
ECODE (Chapter Code)
What: Unique identifier for Red Cross chapters
Format:
Numeric code (e.g., 1019, 38300)
Why better:
"Red Cross of Kentucky" vs "American Red Cross Kentucky Region" vs "ARC
Kentucky" - all refer to the same chapter, but 1019 is always
correct.
RCODE (Region Code)
What: Unique identifier for Red Cross regions
Format:
Alphanumeric (e.g., 01R04, 38R28)
Why better: Region names change over time, but codes remain stable. "Southeast Region" might become "Southeast and Caribbean Division" - the code stays the same.
DCODE (Division Code)
What: Unique identifier for Red Cross divisions
Format:
Alphanumeric (e.g., D25, D27)
Why better:
Division names are long and can be abbreviated differently. D25
is always "Southeast and Caribbean Division" regardless of how it's written.
Key Benefits:
- No spelling variations (Jefferson vs Jeffersons vs Jefferson County)
- No ambiguity (Dallas city vs Dallas County vs Dallas Parish)
- Standardized format (always 5 digits for FIPS, always consistent)
- Never change (names change, codes stay the same)
- Perfect for joins (codes match exactly, names require fuzzy matching)
- International standards (FIPS is federal standard, ZIP is USPS standard)

- Run the script: Open an ArcGIS Online Notebook, paste the script, and run it. The notebook is already authenticated — no tokens needed. It creates all dashboards and prints the results
- Get your results: Paste the notebook output back here, then download the final 3-column CSV: PowerBI URL | Orgler URL | Dashboard URL
Extract field names from an ArcGIS Online feature layer and generate inline CSS + HTML pop-up templates ready to paste into ArcGIS Experience Builder, Map Viewer, or Dashboards.
🤖 Pro Workflow: Use AI to Create Beautiful Pop-ups! (Click to expand)
🚀 The Smart Way to Create ArcGIS Pop-ups
ArcGIS pop-ups require INLINE CSS—all styles must be embedded
directly in the HTML using
style="..."
attributes.
External stylesheets and <style>
tags don't work!
ChatGPT, Claude, and other AI assistants excel at creating inline CSS. Provide your field names and design requirements, and they'll generate production-ready pop-up HTML.
📋 Recommended Workflow:
Use this tab to parse field definitions from your FeatureServer → Get clean field list
Example prompt to ChatGPT/Claude:
Copy the AI-generated HTML → Paste into ArcGIS pop-up configuration → Instant professional pop-up!
- Always specify "inline CSS" or "all styles in style attributes"
- Mention your color scheme (Red Cross: #DC143C, #c62828)
- Request specific layouts: table, card, header+sections, etc.
- Ask for formatting: commas in numbers, date formatting, currency symbols
- Include emojis or icons for visual appeal (📍 🏘️ 💰 📊 ✅)
- Test in one pop-up, then apply to all features!
How to Use:
- Open your ArcGIS FeatureServer REST page (e.g.,
.../FeatureServer/0) - Scroll down to the Fields: section
- Copy all the field definitions (the entire list showing field names, types, and aliases)
- Paste them into the box below
Quick Reference:
After parsing fields:
- Select which fields to include in your pop-up
- Optionally add a pop-up title
- Optionally group related fields together (e.g., all 2022-2025 fields in one group)
- Click "Generate Pop-up HTML"
- Copy the generated HTML and paste it into ArcGIS Experience Builder or Map Viewer pop-up editor
Note: Generated HTML uses inline CSS matching American Red Cross color standards (#c8102e) and compact Economist-style typography.

📋 What This Does
Could be a daily export, manual upload, or automated report
Get the SharePoint sharing link or OneDrive sync path
Using ArcGIS Notebooks (cloud) or Python scripts (local Mac)
Every day, hour, or whenever you schedule it
Ask the data owner to:
- Upload their CSV file to SharePoint or OneDrive
- Right-click the file → Share → Copy Link
- Send you the link (looks like:
https://redcross.sharepoint.com/...)
- Go to ArcGIS Online → Content
- Find your feature layer (or create a new one from the CSV first)
- Open the item page
- Look at the URL:
https://redcross.maps.arcgis.com/home/item.html?id=abc123def456 - Copy the ID (the part after
id=)
0ac831210d79488481ebe52b4beba35d
- In ArcGIS Online, go to Content → New Item → Notebook
- Choose Python 3 runtime
- Name it something like "Daily CSV Update - [Your Layer Name]"
- Click Create
Copy and paste this code into a notebook cell:
from arcgis.gis import GIS
from arcgis.features import FeatureLayerCollection
import pandas as pd
# Connect to ArcGIS Online (you're already logged in!)
gis = GIS("home")
# Configuration
SHAREPOINT_CSV_URL = "YOUR_SHAREPOINT_LINK_HERE"
FEATURE_LAYER_ID = "YOUR_LAYER_ID_HERE"
# Download CSV from SharePoint
print("📥 Downloading CSV from SharePoint...")
df = pd.read_csv(SHAREPOINT_CSV_URL)
print(f"✅ Loaded {len(df)} rows")
# Get the feature layer
print("🔍 Finding feature layer...")
item = gis.content.get(FEATURE_LAYER_ID)
flc = FeatureLayerCollection.fromitem(item)
layer = flc.layers[0]
# Delete all existing features
print("🗑️ Deleting old features...")
layer.delete_features(where="1=1")
# Add new features from CSV
print("📤 Uploading new features...")
features = df.to_dict('records')
layer.edit_features(adds=features)
print("✅ Update complete!")YOUR_SHAREPOINT_LINK_HERE and YOUR_LAYER_ID_HERE with
your actual values!
- Click Run on the cell
- Watch the output - you should see "✅ Update complete!"
