1. The Ever-Evolving world of Aerial Imagery - Oblique Style
2. Oblique Aerial Imagery and GIS Georeferenced oblique imagery is changing how GIS professionals distribute data. By sharing this vital information with other agencies, GIS departments become an even more vital resource to all entities in their organization.
3. Agenda • What is Oblique Imagery? • The Value and Benefits of Oblique Imagery • Using Oblique Imagery within your GIS • How to Shop • Discussion
4. Nadir (vertical) vs. Oblique
5. 2.5” 4” 5.5” Oblique Image Resolution varies from Front to Back Oblique Image Resolution (Ground Sample Distance)
6. Major Differences: Ortho vs. Oblique • Oblique Imagery has a “Non Traditional” image footprint • Oblique Imagery does not have a uniform pixel resolution (GSD) • Oblique Imagery offers the ability to measure Height and other unique aspects • Oblique Imagery provides a 360 degree view of any location
7. Major Differences: Ortho vs. Oblique (cont.) • Oblique imagery is not based on Rectilinear grid system like typical GIS or Orthoimagery (this is why there is a need for custom software solutions)
8. Traditional Ortho Image Oblique Image
9. So In Addition To This… You Get This…
10. General Benefits of Oblique Imagery • Requires “less trained interpretation” of an image • Reduces or even eliminates field visits - users can “simulate” field visits from the office • When in the field, oblique imagery allows field crews an “over the fence” view of a property • Increase accuracy (data verification & collection) • Easier and more advanced Information gathering through analysis and measurements • Makes GIS more familiar to the masses. The more folks you have using your GIS, the more recognition, funding, and kudos you receive.
11. Assessment Benefits of Oblique Imagery • Increase productivity and reduce the cost of field visits by pre-reviewing properties from the desktop, tailor visits and trips to be more effective and productive from your desktop (do half of the work with the mouse) • Check high resolution oblique and orthogonal imagery (up to 3” GSD) providing multiple views of difficult to access properties and help improve communication during an appeals process (access locked gates, avoid dangerous properties, see the middle of the woods) • Accurately calculate areas, distances and heights, and a choice of deployment and integration options helps meet your workflow requirements (again, do half of the work with the mouse)
12. Law Enforcement Benefits of Oblique Imagery · Identify staging and surveillance areas · Search, raid, and seizure planning · Photo documentation for search warrant applications · Traffic control analysis, evacuation planning, and routing · Land/air coordination in search and rescue efforts · Turn night into day-winter into summer · Identify ingress / egress points
13. 911 Benefits of Oblique Imagery · Instantly view multiple images of caller location at time of call · View address from multiple angles for entry and escape points · Measure height, length and width of buildings · Provide remote guidance on location of electrical wires and other obstacles that might impair equipment or helicopter access · Integrate third-party information such as dispatch software and records management systems · Monitor foot chases through visual clues and provide assistance to officers on the scene · Using visual clues, help identify true location of incidents that are called in that may not be the actual incident areas
14. Fire Department Benefits of Oblique Imagery · Preplan responses for major structures and facilities · Locate and establish field command centers · Zoom in and inspect structural compositions, roof layout, and access points
15. How Can You Use Oblique Imagery within your existing GIS? • Proprietary Desktop Software • Web-based Solutions • Full Browser Apps • iPad Apps • Smartphone Apps (Android and iOS) • Esri – integration options with ArcGIS Desktop/ArcMap and ArcGIS Server via custom applications or ArcGIS Viewer applications • Autodesk – direct integration with Autocad • SDKs are available for customers and business partners to build custom integrations within a variety of environments, utilizing both desktop and web technologies • Various GIS, CAMA and 911 mapping vendors already offer existing, proven integrations with their software packages
16. • Unlimited Seat License • GIS Support – ArcSDE & Shapefile support – On-the-fly reprojection from any coordinate system – No conversion or additional tools needed to overlay GIS layers – Query Information from GIS attributes with Query Tool – Custom Searching based on any GIS attribute Proprietary Desktop Software
