Open satellite maps via deeplinks. Capture at multiple zoom levels. Analyze land/structures.

🚀 CRITICAL: Address-First Approach (FASTEST METHOD)

ALWAYS try the address directly in the URL first. Both Google Maps and Apple Maps auto-geocode addresses - no parsing needed!

Apple Maps (Preferred - Native macOS, Fastest)

# Satellite view with address (Apple Maps auto-geocodes)
open "maps://?q=110+Clover+St+Cedar+Creek+Texas&t=h"

# Satellite view with coordinates and zoom
open "maps://?t=h&ll=30.0872,-97.5014&z=18"

Google Maps (Alternative - Browser-based)

# Satellite view with address (Google Maps auto-geocodes)
open "https://www.google.com/maps/search/110+Clover+St+Cedar+Creek+Texas/@?layer=satellite"

# Satellite view with coordinates and zoom
open "https://www.google.com/maps/@30.0872,-97.5014,18z/data=!3m1!1e3"

Force Satellite View with AppleScript

# Activate Maps and set to satellite view (Cmd+3)
osascript -e 'tell app "Maps" to activate' \
  -e 'delay 1' \
  -e 'tell app "System Events" to keystroke "3" using command down'

Only Geocode If:

• ❌ You need exact lat/lon for calculations
• ❌ The address format is unusual or international
• ❌ You're doing multi-location analysis with coordinates

NEVER waste tool calls geocoding when the address works directly in the URL!

Obtaining Coordinates

From Address (Geocoding - No API Key)

# Nominatim/OpenStreetMap - replace spaces with +
ADDRESS="123+Main+St,+Des+Moines,+Iowa"
curl -s "https://nominatim.openstreetmap.org/search?q=${ADDRESS}&format=json" | jq -r '.[0] | "\(.lat),\(.lon)"'

From Device Location (macOS)

# Requires Location Services enabled in System Settings > Privacy
osascript -e 'tell application "System Events" to get the value of location'

# Alternative: Use CoreLocation via swift (more reliable)
swift -e 'import CoreLocation; let m=CLLocationManager(); if let l=m.location { print("\(l.coordinate.latitude),\(l.coordinate.longitude)") }'

From IP (Approximate - Fallback)

curl -s "https://ipapi.co/json" | jq -r '"\(.latitude),\(.longitude)"'

Manual Lookup

• Google Maps: Right-click location → "What's here?" → coordinates appear at bottom
• Apple Maps: Long-press to drop pin → tap pin → coordinates in info panel
• What3Words: Convert 3-word address at what3words.com

From Property Address (Google Geocoding)

# If you have Google API key
curl -s "https://maps.googleapis.com/maps/api/geocode/json?address=123+Farm+Rd,+Iowa&key=YOUR_KEY" | jq -r '.results[0].geometry.location | "\(.lat),\(.lng)"'

URL Patterns (Use with bash open command)

Google Maps Satellite

https://www.google.com/maps/@{LAT},{LON},{ZOOM}z/data=!3m1!1e3

• ZOOM: 1-21 (21=max detail, 18=buildings clear, 15=property, 12=region)

Google Earth Web

https://earth.google.com/web/@{LAT},{LON},{ALT}a,35y,0h,0t,0r

• ALT: altitude in meters (500=high detail, 2000=overview)

Bing Maps Aerial

https://www.bing.com/maps?cp={LAT}~{LON}&lvl={ZOOM}&style=a

Sentinel Hub (Agricultural/NDVI)

https://apps.sentinel-hub.com/eo-browser/?zoom={ZOOM}&lat={LAT}&lng={LON}

ESRI World Imagery

https://www.arcgis.com/home/webmap/viewer.html?center={LON},{LAT}&level={ZOOM}

Execution Examples

Method 1: Direct Address (FASTEST)

# Apple Maps - Single command for address + satellite + screenshot
open "maps://?q=110+Clover+St+Cedar+Creek+Texas&t=h"
sleep 4
screencapture -x ~/Desktop/satellite_capture.png

Method 2: Address with Multi-Zoom (Apple Maps)

ADDRESS="110+Clover+St+Cedar+Creek+Texas"

# Regional view (zoom 12)
open "maps://?q=${ADDRESS}&t=h&z=12"
sleep 4
screencapture -x ~/Desktop/overview_z12.png

# Property level (zoom 16)
open "maps://?q=${ADDRESS}&t=h&z=16"
sleep 4
screencapture -x ~/Desktop/property_z16.png

# Structure detail (zoom 19)
open "maps://?q=${ADDRESS}&t=h&z=19"
sleep 4
screencapture -x ~/Desktop/structures_z19.png

Method 3: Coordinates with Multi-Zoom (Google Maps)

LAT=37.7749; LON=-122.4194

# Regional context
open "https://www.google.com/maps/@${LAT},${LON},12z/data=!3m1!1e3"
sleep 4
screencapture -x ~/Desktop/z12.png

# Property level
open "https://www.google.com/maps/@${LAT},${LON},16z/data=!3m1!1e3"
sleep 4
screencapture -x ~/Desktop/z16.png

# Structure detail
open "https://www.google.com/maps/@${LAT},${LON},19z/data=!3m1!1e3"
sleep 4
screencapture -x ~/Desktop/z19.png

Method 4: With AppleScript for Reliable Satellite View

# Uses AppleScript to force satellite mode and fullscreen for better quality
osascript <<'EOF'
property theAddress : "110 Clover St, Cedar Creek, Texas"

-- Open Apple Maps with satellite view
do shell script "open 'maps://?q=" & theAddress & "&t=h'"

tell application "Maps"
    activate
end tell

delay 2

-- Force satellite view (Cmd+3)
tell application "System Events"
    tell process "Maps"
        keystroke "3" using command down
    end tell
end tell

delay 4

-- Fullscreen for better screenshot
tell application "System Events"
    tell process "Maps"
        keystroke "f" using {command down, control down}
    end tell
end tell

delay 1

-- Capture
do shell script "screencapture -x ~/Desktop/satellite_" & (do shell script "date +%Y%m%d_%H%M%S") & ".png"
EOF

Screenshot commands

screencapture -x ~/Desktop/capture.png          # Silent full screen
screencapture -i ~/Desktop/selection.png        # Interactive select
screencapture -T 5 -x ~/Desktop/delayed.png     # 5 second delay

Visual Verification (CRITICAL STEP)

After opening the map, ALWAYS verify you're looking at the correct location!

# After capture, analyze the screenshot to confirm the address
# Use image analysis to check that the location markers and labels are correct
# If location is wrong:
#   1. Check the address spelling
#   2. Try full address with ZIP code
#   3. Use explicit coordinates instead
#   4. Re-open map and re-capture

Why This Matters:

• Last session used approximate town coordinates (Cedar Creek center) instead of actual property
• Result: 4 wrong screenshots wasted before discovery
• Prevention: Analyze first screenshot to confirm correct location before multi-zoom sequence

Complete Workflow (Agent Must Follow)

Step 1: Detect Input Type

- User provides ADDRESS → Use directly in URL (Method 1 or 2)
- User provides COORDINATES → Use in URL (Method 3)
- User says "my location" → Get device location first

Step 2: Open Map with Address/Coordinates

# Preferred: Apple Maps (faster, native)
open "maps://?q=ADDRESS&t=h"

# Alternative: Google Maps (browser-based)
open "https://www.google.com/maps/search/ADDRESS/@?layer=satellite"

Step 3: Wait for Tiles

sleep 4  # Allow satellite imagery to load fully

Step 4: Capture Screenshot

screencapture -x ~/Desktop/satellite_$(date +%Y%m%d_%H%M%S).png

Step 5: Visual Verification

# Analyze the screenshot:
# - Does it show the correct address?
# - Are the location labels visible?
# - Is the satellite view active (not road view)?
# If NO → Adjust and re-open map

Step 6: Multi-Zoom Analysis (Optional)

# If more detail needed, repeat steps 2-5 at different zoom levels:
# - zoom 12 (regional)
# - zoom 16 (property)
# - zoom 19 (structures)

Zoom Level Reference

Provider Selection

Farm Analysis Workflow

1. Overview (zoom 12): Regional context, access roads
2. Property (zoom 16): Boundaries, field divisions
3. Structures (zoom 19): Building inventory
4. Crop Analysis: Use Sentinel for vegetation indices

Coordinate Format

Use Decimal Degrees (DD):

• Latitude: -90 to 90 (negative = South)
• Longitude: -180 to 180 (negative = West)
• Example: 37.7749, -122.4194

Output Organization

Save captures to organized folders:

~/Desktop/farm_analysis/
├── overview/    (zoom 10-14)
├── property/    (zoom 15-17)
├── structures/  (zoom 18-21)

Integration

Use bash tool to execute open commands. Use sleep 3-5 between URL and screenshot to allow tiles to load. Maximize browser window for best capture quality.
