Spokane Washington coordinates revealed
The precise geographic coordinates for Spokane, Washington are approximately 47.6588° N, 117.4260° W. This location places Spokane in the eastern part of the state along the Spokane River, near the Idaho border and within the Pacific Northwest's high-desert-to-forested transition zone. This article provides a structured, data-rich overview of Spokane's coordinates, historical context, and practical implications for mapping, navigation, and regional planning.
Core coordinates at a glance
For quick reference, Spokane's central coordinates in decimal degrees are about 47.6588, -117.4260. These figures align with multiple reputable mapping and geospatial sources that describe Spokane's location within the Spokane River Valley. The values are commonly used in GIS workflows, GPS devices, and mapping APIs. Geospatial accuracy at street level may vary by a few hundred meters depending on the datum and vertical reference used.
- Latitude: 47.6588° North
- Longitude: -117.4260° West
- Elevation: approximately 570-600 meters (about 1,870-1,970 feet) above sea level
Historical and contextual coordinates
Spokane's coordinate system has evolved alongside cartographic practices since the 19th century. Early surveys used local datums that differed from today's WGS84 standard, leading to minor discrepancies when comparing historical maps with modern GPS readings. By the mid-20th century, Spokane's central coordinates aligned closely with contemporary decimal-degree representations used by global navigation systems. This alignment supports consistent navigation and regional planning, cementing Spokane's place as a defined geographic node in the Inland Northwest. Historical datum transitions are important for researchers cross-referencing older maps with current GIS layers.
- 19th-century surveys established the initial city center; coordinate approximations round to a few minutes of arc.
- Mid-20th-century geodetic refinements adopted standard datums, reducing regional offsets.
- Today, most digital maps use decimal degrees around 47.6588, -117.4260 for city-scale queries.
Why coordinates matter for Spokane
Knowing Spokane's coordinates is essential for multiple practical purposes, including emergency response routing, infrastructure planning, and tourism logistics. Coordinated data enable precise mapping of healthcare facilities, schools, and critical utilities across the city. In the broader region, accurate coordinates support cross-border collaborations with Idaho and British Columbia through shared GIS datasets. Coordinate accuracy underpins reliable navigation and public safety operations.
Geospatial nuances and data standards
Geospatial data for Spokane are typically published in multiple formats-decimal degrees, degrees-minutes-seconds (DMS), and more specialized formats like UTM. In practice, decimal degrees (47.6588, -117.4260) are preferred for most software, while DMS (47° 39' 31.7" N, 117° 25' 33.6" W) is common in traditional cartography. This article uses decimal degrees for clarity and interoperability. Interoperability standards enable Spokane to be integrated into federal, state, and local GIS projects seamlessly.
| Coordinate Type | Value | Notes |
|---|---|---|
| Latitude (decimal degrees) | 47.6588° N | Central city reference point |
| Longitude (decimal degrees) | -117.4260° W | Central city reference point |
| Latitude (DMS) | 47° 39' 31.7" N | Alternative notation |
| Longitude (DMS) | 117° 25' 33.6" W | Alternative notation |
| Elevation | ~570-600 m (1,870-1,970 ft) | City valley floor |
Practical use cases
1) Mapping and navigation: Deliver precise routes for delivery fleets, public transit planning, and ride-hailing services that operate in Spokane and its environs. 2) Emergency services: Establish tight geofences and optimized dispatch zones to improve response times. 3) Urban planning: Integrate coordinates with zoning, utilities, and climate resilience datasets to model future growth. 4) Tourism and events: Pinpoint venues, hotels, and emergency assembly points during large gatherings. In these contexts, reliable coordinates underpin operational efficiency and public safety. Operational efficiency hinges on stable coordinate references across platforms.
Common coordinate formats and conversions
For audiences who work with multiple systems, Spokane coordinates may be requested in several formats. Decimal degrees are standard for most programming languages and web APIs. DMS is often preferred by human readers and printed maps. UTM zone 11S is another format used in engineering contexts, aligning with the region's roughly 6-degree east-west span. Conversion between formats is routine but should be performed with validated tools to avoid rounding errors. Format compatibility ensures data flows smoothly between desktop GIS, mobile apps, and backend services.
Data provenance and reliability
Coordinate values cited for Spokane can be cross-validated across multiple reputable sources, including major mapping services, government GIS datasets, and educational resources. Typical figures-47.6588, -117.4260-are reproduced consistently across these outlets, reinforcing their reliability for day-to-day use and professional planning. When precision matters for critical operations, practitioners often reference primary geodetic datasets and confirm with field surveys. Cross-source verification minimizes risk of mislocation in high-stakes applications.
Frequently requested questions
Local context and regional footprint
Spokane's coordinates anchor a city that functions as a regional hub for health care, education, and technology in the Inland Northwest. The coordinate system supports neighboring communities in Washington and Idaho through shared infrastructure datasets, aiding regional emergency planning and transport networks. In practice, Spokane serves as a testbed for multi-jurisdictional GIS projects, leveraging precise coordinates to coordinate cross-border initiatives. Regional integration is enhanced by consistent geospatial references across agencies.
Illustrative scenarios and data sample
To illustrate how Spokane coordinates feed real-world decision-making, consider:
- Scenario A: Emergency response routes are computed using the central coordinates to generate nearest-vehicle dispatch plans within a 10-kilometer radius.
- Scenario B: A city planning study uses coordinates to align new housing developments with existing transit corridors at precise street intersections.
- Scenario C: A tourism app maps hotels within a 5-mile buffer of the Spokane River, leveraging decimal-degree coordinates for fast queries.
While the central point 47.6588, -117.4260 is a practical default, many applications also store alternative reference points within the city center to accommodate street-level routing and pedestrian navigation. In sum, Spokane's coordinates are not just numbers; they are operational keys for a city that blends river valley geography with a growing knowledge economy. Operational keys unlock efficient services and resilient planning across the region.
