Click to edit Master title style Click to edit Master title style Capture specifications

No change to “basic package” feature specs EXCEPT sidewalks got more Type attributes and will now be collected at a 3ft minimum.

  • A "sidewalk" is a paved path for pedestrians; most often on the side of the road.
  • A “crosswalk" is a marked (painted) part of the paved road where pedestrians have right of way to cross.

Crosswalks within parking lots are not included.

  • A “possible missing sidewalk” is an area on the side of a road where a sidewalk appears to be missing.

An indication of a missing sidewalk would be existing sidewalks in the surrounding blocks. This feature should not be paved and should not cross the road. Segments with this attribution can be delineated up to 650 feet to maintain connectivity in the layer.

  • A “possible missing crosswalk” is a crossing of a major street that doesn’t currently have crosswalk paint
  • markings. Major streets are indicated by road surface markings. Segments with this attribution can be

delineated up to the width of the street to maintain connectivity in the layer.

  • An “other path” is a line segment that doesn’t meet criteria for the other types but needs to be included in

the data set to maintain connectivity. An example would be a sidewalk or possible missing sidewalk that breaks at a parking apron. The section that covers the parking apron would be an “other path.” Segments with this attribution can be delineated up to 650 feet to maintain connectivity in the layer.

  • A “best-fit line” is a straight feature drawn through a decorative sidewalk pattern (e.g. on a school

campus). It indicates that a sidewalk is there but does not trace all pedestrian possibilities.

Click to edit Master title style Click to edit Master title style Capture specifications – new features

  • Impervious surface
  • Contains all polygon impervious surface layers that are itemized above (e.g. building

roofprints, parking lots, driveways etc) and all other impervious features that we have not yet collected (e.g. paved areas, pools etc). Minimum capture size is 100 sq ft. When including itemized layers, some attributed features are dropped (e.g. pervious from parking). Private property is included.

  • Poles and signs
  • Collect all visible poles/signs from the imagery within ROW and public lands.
  • Pavement markings
  • Collect pavement markings within right of way, including road lanes and crossings.

Areas with pavement markings of different types will have a LineType attribute of what the predominant line type is. Lines will be broken for LineType attribute purposes only if greater than 100 feet in length. Faded paint lines will be captured as whatever the predominant LineType is. Dashed line markings will be captured as one line with a LineType of “Broken”. Pedestrian crossings to be captured as a center line of each corner to corner crossing. Parking lines and hashed lines will not be collected. Temporary pavement markers (such as those present in construction zones) will not be captured.

Click to edit Master title style Click to edit Master title style Extents

New grid layout

  • Faster to build the project area
  • More efficient for the vendor
  • Easier to communicate extents (most

match now)

  • Corresponds to DRAPP imagery tiles
  • Increased cost  but DRCOG and the

vendor absorbed the cost Extent for basic package: building roofprints, edge of pavement, parking, ramps, trails, sidewalks

2016 – poly and line sidewalk extents do not match 2018 – poly and line sidewalk extents match Why did DRCOG fund this expansion? To enable the calculation of sidewalk widths.

Click to edit Master title style Click to edit Master title style Value-adds for funding partners

  • Extra attribution
  • Sidewalk widths – provided by Felsburg,

Holt, & Ullevig (FHU)

  • Building addresses – provided by

BuildingFootprintsUSA

  • Deliveries in Q1 2019 (using 2016 data)

and in Q1 2020 (using 2018 data)

  • Not public domain data – only for funding

partners!

Click to edit Master title style Click to edit Master title style Sustainable funding model (?)

Two product-types

  • 1. Foundational, regional data

sets with detailed geometries and limited attribution (open to all)

  • 2. Value-added data sets with

additional attribution (restricted to funding partners)

Partners fund open data Open data is consumed by everyone Some users add more value Added value is shared back only to funding partners

Click to edit Master title style Click to edit Master title style Maximizing ROI

  • Distribute data to all potential

users – tell your colleagues!

  • Share the use cases so the

community can build on each

  • ther’s innovations
  • Publicize the project to managers

and budget-approvers

  • How can quantify the value?

Click to edit Master title style Click to edit Master title style Upcoming data trial

  • Ecopia Tech creates planimetric data through an automated feature extraction

process.

  • They created the building footprints currently being sold by Digital Globe:

https://www.digitalglobe.com/products/building-footprints

  • They are currently in talks with Nearmap about a partnership to create

planimetrics from their imagery (I think).

  • They believe they can capture most of the features we require and are willing

to provide us with sample data to evaluate – More info on this soon.

  • If we have interest in their product, we could consider pursuing it for the 2020

Regional Planimetric Data Project.
