Title: 2010 CoC Boundaries

Geospatial_Data_Presentation_Form: vector digital data

Description:

Abstract:

The dataset contains the geographic boundaries for The U.S. Department of Housing and Urban Development's Continuum of Care (CoC) areas. The dataset is current for 2010 and contains the geographic boundaries for all of the 2010 claimed CoC areas and includes funding status information.

Purpose:

The U.S. Department of Housing and Urban Development is providing these data sets for use by continuum of care grantees, homeless services planners and research institutions. Because HUD provides competitive funding for homeless services through a continuum of care structure that is developed at the local level, outside research based on this structure cannot be accomplished without the provision of the geographic boundaries and related data provided herein. Therefore, this data set was developed to make the Continuum of Care process and funding as transparent as possible to the public.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Non-internal attributes are all HUD provided data and are accurate for the 2010 CoC calender year.

Logical_Consistency_Report:

The data set is composed of an aggregate of State and Territory, County, Municipal and County Subdivision (Township) boundary data. The resulting aggregate polygons have been cleaned and are accurate representations of the CoC geographic areas as decscribed by the HUD geocodes. Polygon accuracy is a function of the original dataset scale and congurency of the different polygon boundary files used to define the CoC boundaries.

Completeness_Report:

The data set is a complete representation of the input HUD geocodes.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The dataset is dervied from original State, County and territory Boundary data at a scale of approximately 1:80,000,000 and County Subdivision data at a scale of approximately 1:13,000,000. The dataset may not be suitable for high-precision measurement applications such as engineering calculations, property boundary analysis, or other uses that might require highly accurate measurements of the earth's surface.

Process_Step:

Process_Description:

In order to create the boundaries for the 2010 Continuums of Care, data was combined through a series of steps based on the HUD geocode definitions. The basis of CoC geographic boundaries are the State (or Territory), County (Municipio in Puerto Rico), County Subdivision (Township) or Municipal (City) boundaries with which each CoC is associated. The boundary for any particular CoC can be a combination of any of the above mentioned geographic boundary categories. CoC boundaries were calculated by the intersection of the above mentioned geographic boundary categories, as defined by the HUD geocodes. The process involved the following steps:
1) Create a list of 2010 CoCs with all the associated type data, geocodes, and CoC ID numbers.
2) Divide the list into its component County, County Subdivision or Municipal associations based on an analysis of the type data and geocode.
3) Join the lists to the corresponding GIS boundary files for County, County Subdivision or Municipalities, and
4) Merge the resulting boundaries and dissolve polygons based on the CoC number to create the appropriate CoC boundaries.
