USER GUIDE

Nancy Guthrie — Catalina Foothills Resource Map

Getting Started

The map loads with the sidebar open on the left. Use the ☰ button to collapse or expand it. Everything runs in your browser — no account or login needed.

Basemap

Pick a basemap style at the top of the sidebar:

• Streets — Default road map (OpenStreetMap)
• Topographic — Terrain contour lines
• Satellite — Aerial imagery (ESRI)
• ESRI Topo — ESRI topographic with labels
• Dark — Low-contrast dark theme

Data Layers

Toggle layers on/off with the checkboxes. Each layer shows a count badge once loaded. Click any marker on the map to see its popup with details.

WiFi Jammer Disruption Zone

This analytical overlay shows the estimated area where consumer WiFi cameras (Ring, Nest, Arlo, Blink, etc.) could be knocked offline by a signal jammer centered on the property. WiFi cameras typically operate on 2.4 GHz and 5 GHz bands, which are vulnerable to broadband RF jammers.

Three zones are shown:

• 30 m — Handheld / low-power. Cheap consumer jammers ($30–$100). Would disrupt cameras on the immediate property and nearest adjacent homes.
• 100 m — Medium-power. Vehicle-mounted or briefcase-style unit. Covers roughly 1–2 surrounding properties in every direction.
• 300 m — High-power / directional antenna. Could blank an entire block. Would reach cameras on surrounding streets and cul-de-sacs.

Criminal Territories & Corridors

This overlay shows known cartel and gang-controlled areas across southern Arizona. Each zone is a semi-transparent polygon that lets the underlying map show through. Hover over a zone to highlight it; click for a detailed intelligence popup with source agencies.

Six zones are included:

• Tohono O’odham Nation — 2.8M-acre reservation with 62-mile Mexico border. Sinaloa Cartel dominant.
• I-19 Corridor — Primary drug/human trafficking pipeline from Nogales to Tucson.
• Barrio Hollywood / AZ New Mexican Mafia — Largest Tucson street gang alliance operating in south/central Tucson.
• Phoenix Distribution Hub — National-level narcotics redistribution center in Maricopa County.
• Cochise Corridor — Secondary smuggling route through Douglas/Agua Prieta to Sierra Vista.
• ◆ Scout Arrest Locations — Diamond markers at known cartel scout/spotter arrest sites (Maricopa, Silverbell Mountains).

Corridor Analysis Tab

Use the MAP / CORRIDOR ANALYSIS toggle buttons at the top of the sidebar to switch between the interactive map and a full traffic estimate document.

The Corridor Analysis tab includes:

• Methodology — How ADOT 2021 AADT data and FHWA hourly factors replace earlier national-average estimates
• Metro baseline — Tucson registered vehicles, road network size, and daily VMT
• Sunday 1-3 AM snapshot — Estimated instantaneous vehicle count (5,000-6,000) with sourced FHWA/DOT ratios
• Breakdown by road type — Vehicles on interstates (now ADOT-derived: 500-2,400/segment), arterials, and local streets
• Who is on the road — Bar close-out, rideshare, shift workers, truckers, etc.
• Egress corridors — Five routes from 5820 N Camino Escalante with distances, drive times, camera density, and ADOT-anchored I-10 vehicle counts at each corridor's interstate entry point
• I-10 camera coverage — ADOT camera spacing from urban core to open desert
• I-10 segment-by-segment AADT — Full 17-segment table (Cortaro to Houghton) with ADOT AADT, K%, T%, and Sunday 1 AM low/mid/high vehicle counts. Peak segment highlighted (Congress-22nd: 1,600-2,400/hr). Source: ADOT 2021 Interstate AADT Publication.
• Case-relevant corridors (ADOT-anchored) — Swan, Campbell, Kolb, and Oracle routes linked to their I-10 segment AADT with derived Sunday 1 AM ranges
• Data confidence summary — Before/after comparison showing which data points upgraded from ESTIMATED to SOURCED or DERIVED
• Cross-reference sources — Where to find harder numbers (Pima County count stations, TPD logs, PAG model, ALPR data)
• Data request list — Five actionable data sources for hourly-level verification: ADOT TDMS ATR data, PAG regional counts, PAG time-of-day model, TPD/PCSD calls for service (FOIA), and ALPR scan counts (FOIA)

Tools

Search

Type an address, intersection, or place name into the search box. Results appear below — click one to fly to that location and drop a marker.

Measure Distance

Click Measure Distance, then click points on the map to draw a path. The total distance shows at the top. Click the button again to stop.

Distance Rings

Drops concentric circles at 1, 2, 3, 5, 10, and 15 mile radii from the map center point. Useful for estimating drive-time ranges.

Drive-Time Isochrones

Shows how far you can drive from the center point in 10, 20, and 30 minutes. Uses the OSRM routing engine. Adjust the center marker to recalculate.

Route Generator

Enter start and end coordinates to calculate a driving route. The route displays on the map with distance, duration, and any cameras along the way highlighted.

Drop Note Marker / Export

Click Drop Note Marker to place a pin on the map with a custom note. Use Clear All Annotations to remove them. When you're done, click Export Notes as GeoJSON to download all your markers as a standard GeoJSON file. This file can be opened in QGIS, Google Earth, kepler.gl, or any GIS tool for further analysis or to share with others.

Crime Intel

The Crime Intel panel queries the Tucson PD Reported Crimes database (ArcGIS Feature Service) in real time. To use it:

1. Pick a division — East (default, covers Catalina Foothills), Midtown, South, West, or All.
2. Pick a time period — last 90 days, 6 months, last year, or all time.
3. Click Load Crime Data.

Results load in the sidebar with a summary count and two sections:

• Priority Offenses — Violent and person-crimes are automatically flagged and shown first (kidnapping, homicide, assault, robbery, sexual offenses, weapons, stalking, threats, etc.).
• Other Top Offenses — The top 20 remaining crime types by count (theft, burglary, fraud, etc.).

Status Panel

The bottom of the sidebar shows a loading status for each data layer:

• Green — Loaded successfully
• Yellow (pulsing) — Loading
• Red — Error (check console for details)

Quick Links

The sidebar includes direct links to external resources: Tucson PD crime dashboards, AZ 511 live camera feeds, police scanners, NamUs missing persons database, Pima County GIS/property records, court records, and more.

Tips

• Zoom with scroll wheel or pinch gestures. The coordinate display (bottom-right) updates as you move your mouse.
• Right-click or long-press a marker to copy its coordinates.
• Layer data comes from OpenStreetMap (Overpass API), AZ 511, and OpenSky Network. Counts may vary depending on API availability.
• The Aircraft layer only loads when you first check it (to save API credits). It shows a snapshot of current airborne traffic — refresh the page for updated positions.
• The Escape Corridor layer is specialized analysis — toggle it on to see surveillance gaps along westbound I-10.
• The Criminal Territories layer automatically zooms out to show the full regional picture when toggled on.
• All data layers start unchecked — toggle on only what you need to keep the map clean.
