MPOJC\u2019s field technicians used an iPad Mini equipped with a cellular data plan to allow online editing of a cloud-based map while out in the field. To collect data accurately and efficiently, technicians used a comprehensive set of definitions for attributes as outlined below. <\/SPAN><\/SPAN><\/P>

Curb Ramps <\/SPAN><\/SPAN><\/P>

The data dictionary employed for the curb ramp inventory was: <\/SPAN><\/SPAN><\/P>

1. Ramp type: Left or Right (perpendicular); Center (diagonal); Under Construction <\/SPAN><\/SPAN><\/P>

2. Detectable warnings (i.e. truncated domes): <\/SPAN><\/SPAN><\/P>

a. None installed <\/SPAN><\/SPAN><\/P>

b. 25 percent damaged <\/SPAN><\/SPAN><\/P>

c. 50 percent damaged <\/SPAN><\/SPAN><\/P>

d. 75 percent damaged <\/SPAN><\/SPAN><\/P>

e. None damaged <\/SPAN><\/SPAN><\/P>

3. Truncated domes aligned with crosswalk: yes/no/unknown <\/SPAN><\/SPAN><\/P>

4. Common panel slope: cross slope over 2%, cross slope less than 2%, no common panel <\/SPAN><\/SPAN><\/P>

5. Ramp running slope: 0-5%, 5-8.3%, 8.3-11%, 11%+ <\/SPAN><\/SPAN><\/P>

6. Receiving ramp on opposite side of street: yes/no <\/SPAN><\/SPAN><\/P>

7. Pavement condition: Good \u2013 no major cracks or uneven areas; Fair \u2013 some major cracks or uneven areas; Poor - major cracks or missing and uneven concrete <\/SPAN><\/SPAN><\/P>

The field technicians relied on ortho-photography to correctly identify the precise point of each curb ramp. After recording the location of each ramp, field technicians used a digital level and tape measure to determine slopes and widths, entered these values in the appropriate data fields, and captured a digital image of the site.<\/SPAN><\/SPAN><\/P>
