Home Screen - implement at a much later phase?

2. Configuration
    1. Set slope measurement methods
        - Educated guess.  No scales used, only looking and standing at a ramp.
          Select "too steep" when in doubt.
        - (default) Low Tech Measure. Use a low-cost scale that may be accurate to .5 degree.
        - Engineering.  Use an electronic level.

Overview Screen

* Zoom/pan/locate
* Base layer- OpenStreetmap streets
* North Arrow (maybe, some indicate this is useless)
* Help Button (phase 3  only)
* Login status (phase 3 only)

* Intersection Layer- Cartodb layer of points.  
Selecting a point navigates to Intersection Screen  

Intersection Screen

* Baselayer, bing maps 
* Corners cartodb points from nodes in walkway network
* Crossings –vectors, generated on the fly in javascript/openlayers
* Named streets ( a cartodb /openlayers layer) (maybe.. would help with orienting)
* North Arrow (Open Layer decoration?)  
* Prompt for crossing Crossing STREETNAME” (open layer text)

* Corner Observation Buttons
    - Perfect Ramp (slope =< 5%, truncated domes, contrast, not black, no obstruction)
    - No ramp
    - Other Ramps
        * good (slope <= 5%, any surface treatment, no barriers, no drainage problem)
        * so-so ( slope between 5% and 8.3%, any surface treatment, no barriers, no drainage problem
        * bad (slope > 8.4%, OR barriers and any slope, drainage problem and any slope, ruined surface)
    - Comments- and these will apply to the entire intersection
        * Too complicated to review
        * Construction Site
    - Skip this button moves to the next curb ramp
    - All like last Sets all curb ramps at this intersection 
     to match the observation of the just completed observation
     DOES THIS SAVE the SLOPE FOR THIS CORNER?
    - Clear This button clears all curb ramp observations

- UI Navigation Buttons. Both selections return to Overview screen
    * Save Observations for this Intersection.
    * Do Nothing- do not review or change this intersection
