UP UPDATIN ATING G TO O A NE A NEW PROJ OJECTION ECTION

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

The Projection

• NAD 83(2011) State Plane Colorado Central FIPS 0502 FT US
• National Adjustment of 2011
• Aligned NGS passive control physical marks and active control system

(CORS)

• CORS coordinates were re-processed using CORS data collected from

Jan ‘94 to Apr ‘11

• Created new realization NAD83(2011) Epoch 2010.00
• CONUS adjusted with 79,546 stations and 1,113 CORS
• New network accuracy: 0.9 cm horizontal, 1.5 cm vertical at 95%

confidence level

• Median change : about 2 cm horizontally and vertically

The Plan

• Project all enterprise ArcGIS data
• Transform the data twice
• Issues:
• Arcpy 10.1 didn’t recognize new projection
• Shuffling of data
• Project all enterprise PostgreSQL data
• Issues:
• Projection not in spatial_ref_sys table in PostgreSQL

9.3/PostGIS

• GeoServer bug?
• Switch out data on the Regional Data Catalog

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

spatialreference.org

• Online repository for spatial reference systems
• SRID = 6428 (SR-ORG 8670)
• OGC WKT confirmed valid
• GeoServer confirmed valid with some tweaking
• PostGIS confirmed valid with some tweaking
• http://spatialreference.org/
• Also some information here:

What This Means For You

• Data from DRCOG will be delivered in this projection
• DRAPP, Planimetrics, Data Catalog, Infogroup, QCEW, etc.
• We encourage your organization to consider moving to the

new realization

• Check with your county surveyor
• Tool to show shifts:
• http://www.ngs.noaa.gov/GEOCON11/
• We are here to help with technical implementation
• We will not be asking for data specifically in this realization

Traffic Operations

• The Traffic Operations Program
• coordination between DRCOG, CDOT, and local jurisdictions
• The Traffic Signal System Improvement Program
• Implement cost-effective traffic signal timing and capital

improvements

• Benefits include:
• Reduce travel time
• Reduce auto emissions
• For more information on our Traffic Operations Program,

visit: https://drcog.org/programs/transportation-planning/traffic-operations-program

The Signal Timing Briefs Map

• DRCOG has developed a new web map that shows the

signal timing projects in our region

• Every year, this map will have the last 10 years of project

data

• Select features to get attribution for the project and view

the signal briefs

• Filter features by project year and view annual reports

Background

• In June 2016, DRCOG

and 21 partners completed a project to develop planimetric features from the 2014 DRAPP imagery.

• Contributions from

DRCOG and a CDOT grant filled in gaps between the 21 partners AOIs – so even if your

• rganization was not a

partner, we may have captured data for you!

Planimetric Update Project – Progress!

• What: updating the 2014 planimetric datasets using the

2016 imagery

• When: Q1 & Q2 of 2017, select vendor by November
• Who: 25 potential partners, looking for more!
• Why: To leverage the data we’ve already captured, keep

data current and useful (remember: updates are MUCH cheaper than new collections from scratch)

• If your organization is interested, please reach out to me at

asummers@drcog.org or 303-480-6746.
